A while back, I wrote an article on cerebral small vessel disease, a very common condition in which the small blood vessels of the brain develop signs of damage.
If you’re an older adult and you’ve had an MRI done of your brain, chances are pretty good that your scan showed signs of at least mild signs of this condition; one study of older adults aged 60-90 found that 95% of them showed signs of these white matter changes.
These are basically like teensy strokes in the brain. Most are un-noticeable to people, but if you have enough of them, you can certainly develop symptoms, such as cognitive impairment, balance problems, or even vascular dementia.
To date, the cerebral small vessel disease article has generated over 100 comments and questions from readers. A common theme was this: “My MRI shows signs of this condition. What can I do?”
As I explain in the article and the comments, the first thing to do is to work closely with your doctors to understand what is the likely cause of the damage to the brain’s small blood vessels.
Now, when you do this, you may well find that your doctor just shrugs, or waves off the question.
That’s because in most people, cerebral small vessel disease is thought to be in large part a result of atherosclerosis (more on this term below) affecting the smaller arteries of the brain. And atherosclerosis affects just about everyone as they age, because it’s related to many basic cardiovascular risk factors that become very common in late-life.
So in many cases, asking the doctor why you have signs of cerebral small vessel disease may be like asking why you might have high blood pressure, or arthritis. These are common conditions and they are usually due to medically mundane causes and risk factors, including sub-optimal “lifestyle” behaviors and the general “wear and tear” on the body that is associated with aging.
(However, in some people, damage to the small vessels in the brain may be related to one or more particular medical conditions. Younger people, in particular, seem more likely to have a particular condition or risk factor that may be causing most of the damage.)
Whether you are younger (i.e under age 60) or older, always start by asking your doctors what they think are the most likely causes for any cerebral small vessel disease, and what they recommend you do to slow the progression.
And for most people, the main advice will be this: evaluate and address your cardiovascular risk factors.
“Vascular,” as you probably already know, means “blood vessels.” And blood vessels are critical to the function of every part of the body, because blood vessels are what brings oxygen and nutrients to every cell in the body. They also carry away waste products and toxins. So, blood vessel health is key to brain health.
This article will help you better understand how to address blood vessel health. Specifically, I’ll cover:
- Understanding cardiovascular risk factors
- 3 key ways blood vessels become damaged
- What is atherosclerosis
- Why some chronic conditions are considered risk factors
- The number one risk factor for future cardiovascular events
- 12 key cardiovascular risk factors
- How to manage cardiovascular risk factors for better brain health
- 5 key approaches most older adults should implement
Note: Experts who study cerebral small vessel disease believe the story of what might be causing it is more complicated. That said, identifying and managing one’s cardiovascular risk factors is currently the mainstay of treatment and is likely to remain so. If you want to learn more about causes and contributors to cerebral small vessel disease, see here: Cardiovascular risk factors and small vessel disease of the brain: Blood pressure, white matter lesions, and functional decline in older persons.
Understanding Cardiovascular Risk Factors Known to Affect Brain Health
Lots of factors affect the health and function of your blood vessels. Before we dive into specific factors, let me share some practical ways to think about these risk factors.
3 key ways blood vessels become damaged
Generally, what is bad for blood vessels will fall into one of the following three categories:
- A form of inflammation: “Inflammation” basically means that aspects of the body’s immune system are revved up. In the short-term, this helps fight infections, but in the longer-term, this actually creates a fair amount of wear and tear on cells in the body. Inflammation can also cause the blood vessels to build up plaque.
- Inflammation is manifested in the body in many different ways. These include having higher levels of certain proteins, such as C-reactive protein, and/or by the increased presence of certain types of white blood cells.
- Many health conditions, including obesity, are associated with chronic inflammation in the body. Aging is also associated with chronic inflammation, a phenomenon sometimes called “inflammaging.”
- For more, see What is Inflammation?
- A form of mechanical stress: This means physical forces — such as higher blood pressure — that create wear and tear on blood vessels.
- A form of mechanical obstruction: This means build-up on blood vessel walls (sometimes called “plaques”) or blockages of blood vessels. A narrower blood vessel cannot transport oxygen, nutrients, or waste products as effectively as before. Plaques can also break off and then block a downstream part of the blood vessel; this can cause strokes or heart attacks.
Some risk factors will fall into more than one category.
What is atherosclerosis?
Atherosclerosis (and its related term, arteriosclerosis) means the process of artery walls becoming inflamed, thickened (by plaques), and then hardened. Calcium is often deposited into the blood vessel wall, which contributes to stiffening and “calcification.” This process of accumulating damage happens over years and years, and is influenced by lifestyle factors, medical conditions, and other health factors.
In short, atherosclerosis is the most common way that blood vessels become slowly damaged and obstructed over time, and this process happens in large part due to chronic exposure to inflammation and mechanical stress.
Hardened arteries will contribute to higher blood pressure. Having a lot of atherosclerosis is also understandably a strong risk factor for developing problems related to blood vessels, such as heart attacks and strokes.
Damaged blood vessels also tend to become less resilient, and so they are also more prone to break or burst. Such breakages can be the underlying cause of ruptured aneurysms and certain forms of stroke.
Why some chronic health conditions are considered cardiovascular risk factors
Certain health conditions are considered cardiovascular risk factors, because research has shown that they are associated with a higher chance of having or developing cardiovascular disease. They can be categorized into two types:
- Health conditions that cause inflammation or other stress on blood vessels:
- Lots of diseases fall into this category, including diabetes and most auto-immune diseases.
- Mental health conditions such as depression or anxiety may also qualify, as these are associated with increased stress levels in the body.
- Health conditions that are often caused by damage to blood vessels.
- This includes chronic kidney disease, which often — but not always — is related to blood vessel health, as well as peripheral artery disease.
The Number One Risk Factor for Future Cardiovascular Events
Probably the top risk factor having a cardiovascular event is having had one in the past.
This is called having “established cardiovascular disease,” or “clinical atherosclerotic cardiovascular disease.” It means a person has already experienced a health event or significant condition related to atherosclerosis. These include:
- Heart attacks (“myocardial infarctions”), especially those related to a blockage in the coronary arteries, which supply blood to the heart
- Strokes, which happen when blood flow to the brain is blocked
- Peripheral artery disease, which happens when large arteries bringing blood to limbs (or sometimes organs) develop significant blockages
Since people with established cardiovascular disease have a higher risk of future cardiovascular events, clinicians are usually more proactive about treating their risk factors, to prevent future events. This is called “secondary prevention.” (“Primary prevention” means treating risk factors in people who have not yet had an event.)
The Rotterdam Study, among others, has found that a history of stroke or heart attack is associated with more signs of cerebral small vessel disease on MRI.
12 Key Cardiovascular Risk Factors that Affect Brain Health
Now that we’ve covered the broader categories of what affects blood vessel health, below is a list of the most common and important specific risk factors. If you’ve been worried about cerebral small vessel disease, these are probably the risk factors you’ll want to be discussing with your doctors.
This list is based in large part on the Uptodate.com chapter on established cardiovascular risk factors.
12 key cardiovascular disease risk factors
- High blood pressure
- High cholesterol, especially high low-density lipoprotein cholesterol (LDL-C) and high triglycerides
- Problems managing blood sugar, including diabetes, insulin resistance, and impaired glucose tolerance
- Chronic kidney disease (defined as an estimated glomerular filtration rate (eGFR) < 60 ml/minute)
- Obesity
- Cigarette smoking
- High levels of inflammation (as measured by C-reactive protein or other tests)
- Obstructive sleep apnea
- Psychological stressors (including depression, anger, anxiety, and stress)
- Insufficient exercise
- Dietary factors, including
- Diets with a high glycemic index or load
- Insufficient fruit and vegetable intake
- Insufficient dietary fiber
- Higher intake of red meat and high-fat dairy products
- Age and gender
Understanding the 12 cardiovascular risk factors in more detail
Now, you may be wondering: how are each of these risk factors defined? What blood pressure is high, or “too high”? What constitutes “insufficient exercise”?
This is where things get tricky. Basically, almost all of these risk factors can be thought of as a risk spectrum, with one side indicating increased cardiovascular risk and the other side associated with less risk. (Although for some factors, extremes on either side are associated with risk).
Where exactly to place a numerical cut-off, for the purpose of defining a disease — e.g. defining “hypertension” — tends to be hotly debated by experts. Similarly, there is often debate as to what constitutes an “optimal range,” or “optimal intake” (for diet and exercise factors), in terms of minimizing cardiovascular risk.
Within this article, it’s not possible to present each factor in depth. Still, here’s a more detailed version of the list with some practical information for each, along with some relevant resources.
Then in the next section, I’ll cover five key approaches, which can address many cardiovascular risk factors simultaneously.
12 Cardiovascular (CV) Risk Factors (more detailed)
- Blood pressure:
- Higher is generally riskier, lower generally corresponds to lower CV risk.
- Treatment of high blood pressure has been associated with a reduction in CV risk.
- For more information: What the New Blood Pressure Guidelines — & Research — Mean For Older Adults
- Cholesterol (also known as “lipids”)
- In general, higher levels of total cholesterol, LDL cholesterol, and/or triglycerides have been associated with higher CV risk.
- Recent guidelines on lipid-lowering recommend basing treatment on a person’s 10-year risk of cardiovascular disease, rather than solely focusing on aiming to get cholesterol below a specific number.
- The recent guidelines also recommend indefinite treatment with a statin drug for all people with proven clinical “atherosclerotic cardiovascular disease.”
- Randomized trials find that treatment of elevated cholesterol (with statins) does reduce CV risk in many people.
- Research also finds that cholesterol levels can be lowered through lifestyle modifications (e.g. changes to diet, weight, and physical activity).
- Blood glucose (blood sugar) and insulin levels
- Higher levels of blood sugar — which usually indicates pre-diabetes or diabetes — are associated with higher CV risk.
- Elevated blood sugar after meals has been associated with increased CV risk, and may be an important risk factor in of itself.
- Controlling blood sugar in people with diabetes has been shown to reduce CV risk.
- That said, studies find that reducing blood sugar too much via medication is also associated with increased cardiovascular risk (see here and here).
- Research suggests that a hemoglobin A1C of 7-7.5% may be safer than using glucose-lowering medications to get the hemoglobin A1C below 7.
- People with diabetes should avoid frequent hypoglycemia.
- Insulin is a hormone that enables the body’s cell to absorb and use glucose. Higher insulin levels are associated with insulin resistance and pre-diabetes. For more information:Â Prediabetes & Insulin Resistance.
- Kidney function
- Chronic kidney disease (usually defined as having an estimated glomerular filtration rate that is chronically less than 60mL/minute) has been associated with increased risk of CV disease.
- A glomerular filtration rate of 90-120 mL/minute is normal, and a rate of 60-90 mL/minute is usually considered mild loss of kidney function.
- For more on chronic kidney disease, including how to diagnose and manage it:Â What Is Chronic Kidney Disease?
- For more on addressing CV risk factors:Â Cardiovascular Disease in CKD
- Obesity
- A higher body-mass index (BMI) has generally been correlated with a higher risk CV disease, as in this study.
- Obesity increases the likelihood of developing other conditions that increase CV risk, including high blood pressure, high cholesterol, insulin resistance, and diabetes.
- Being overweight does seem to become less risky as one ages; learn more about the “obesity paradox” here and here. Some experts also believe that waist circumference is a more useful measurement than BMI in older people.
- Tobacco smoking (and other forms of inhaling toxins)
- Smoking cigarettes is a well-established and strong risk factor for CV disease. The CDC estimates that smoking causes one in three deaths from cardiovascular disease.
- Second-hand smoke exposure is also associated with CV risk.
- Smoking is also known to particularly cause damage and inflammation to blood vessels.
- Research finds that quitting at any age helps people live longer.
- Note: Some smokers switch instead to vaping. This is better than smoking cigarettes, however the long-term effects and risks of vaping have yet to be established.
- Inflammation (as measured by C-reactive protein or other tests)
- C-reactive protein C-reactive protein is synthesized by the liver and is considered a good marker of inflammation in the body.
- Higher levels of C-reactive protein can be caused by a variety of specific health conditions. They may also reflect more generalized chronic inflammation in the body.
- Research has found that C-reactive protein levels often correlate with the degree of existing atherosclerosis in a person’s blood vessels, and also with the risk of future CV events.
- Statins have been shown to lower C-reactive protein levels, independent of their effect on LDL cholesterol levels. This may be part of the way that statins reduce the risk of CV events.
- Using C-reactive protein to screen people without symptoms of CV disease is controversial, mainly because it’s unclear that this improves outcomes (compared to using the risk factors included in a “traditional” cardiovascular risk calculator.)
- Obstructive sleep apnea
- Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder
- People with OSA have a higher risk of experiencing CV events.
- Treatment of OSA has been associated with improvement in high blood pressure and some other cardiovascular factors. However, a recent meta-analysis found that OSA treatment with positive airway pressure did not result in fewer CV events.
- Psychological stressors
- Research has linked psychological conditions, including depression, anxiety, and chronic stress, to CV risk.
- A randomized study found that stress-management training was associated with improved markers of CV risk, in people with pre-existing heart disease. Another study found that depression treatment reduce the risk of a first CV event.
- Exercise and physical activity levels
- Generally, greater amounts of exercise and regular physical activity correlate with decreased CV risk, as noted in this study.
- A recently published analysis of data from the LIFE randomized trial found that in a previously sedentary group aged 70-89, increased physical activity (as measured by a wearable device) did correspond to a lower risk of experiencing cardiovascular events.
- Guidelines generally recommend that people aim for 150 min/week of moderate aerobic physical activity, or 75 min/week of vigorous aerobic activity. However, research suggests that lesser amount of exercise also can provide benefit, so some exercise is always better than none. For a review of the effect of exercise on cardiovascular outcomes, see here.
- My top recommendations on exercise and aging are here: 4 Types of Exercise in Later Life: How to maintain strength, balance, & independence in aging.
- Dietary factors
- Research generally suggests that higher intakes of dietary fiber, fruits, and vegetables are associated with a lower risk of CV disease. Newer research suggests that the benefits of these foods is at least in part due to their impact on the gut microbiota (the “good bacteria” in every person’s gut).
- Research also suggests that a plant-based diet (one with no or minimal animal products, and minimal processed foods) can lead to significant reductions in CV risk.
- Red meat consumption has been associated with a higher risk of CV disease in some research, including this study.
- The risks and benefits of eating different types of fat or other animal products remain debated.
- Although many observational studies suggest that diets with a lower glycemic load are associated with lower CV risk, randomized trials have not always confirmed that such diets improve CV risk markers such as cholesterol or inflammation markers.
- A very interesting study published in 2015 found that individuals have very different blood sugar responses to the same meal. This suggests that low glycemic diets may be more effective for some people than for others.
- Age and gender
- CV risk generally goes up as people get older.
- CV risk factors affect both genders but may do so differently, depending on the factor.
How to manage cardiovascular risk factors for better brain health
Again, if you’ve become concerned because brain scans have shown signs of cerebral small vessel disease, your very first step should be to talk to your healthcare providers. Ask them what they think are the most likely causes of the brain changes that are visible on the scans.
No matter what they say, you’ll probably still want to review and address cardiovascular risk factors.
(A possible exception: it might not be worthwhile for a person who has become quite debilitated and whose goals of medical care are mostly prioritizing comfort, such as someone with advanced Alzheimer’s or another advanced illness. For more on goals of care, see this article.)
Now how should you do this? You might think that the answer is to work away to evaluate and treat each one of those factors.
That’s not necessarily a bad idea, but it can be quite labor-intensive. It also carries the risk of “falling down the rabbit hole,” since exactly how to treat some of these risk factors — such as cholesterol — is hotly debated by medical experts.
So instead of delving into the nitty-gritty and attempting to optimize each risk factor, I recommend starting by considering a handful of high-yield “better health” approaches. Studies generally find that these do correspond with lower cardiovascular risk.
5 better health approaches to help reduce cardiovascular risk
Below are my top recommendations. These are beneficial to most older adults. Check with your doctors to confirm that this approach is likely to benefit you or your older relative, or to troubleshoot any concerns or questions you might have.
- Avoid tobacco smoke.
- If you’re a smoker, stopping is one of the most powerful ways to reduce inflammation in your blood vessels, so get help quitting smoking.
- If you live with a smoker, see if you can persuade that person to stop, for their own health and for yours.
- Bonus benefits:
- Quitting smoking will improve lung function within days, and will reduce cancer risk. It will also save you money.
- For resources on helping older adults quit:Â Quitting Smoking for Older Adults.
- Get more exercise.
- Most older adults don’t currently get the recommended amount of exercise (150 min/wk of moderate exercise or 75 min/wk of vigorous exercise).
- It’s generally best to start by assessing one’s current level of exercise, and then making an effort to modestly increase one’s weekly exercise. A step-tracker is often very helpful.
- Trying to walk more is a good goal for many older adults.
- Sedentary older adults may benefit from enrolling in programs to help them exercise.
- If pain, shortness of breath, falls, or other problems are limiting one’s ability to walk or do other exercise, be sure to ask your health providers for help.
- Bonus benefits:
- Increased exercise has been associated with countless benefits, including maintenance of mobility, improved mood, better sleep, better brain function, and more.
- For more on exercise in later life, including my top recommendations, see 4 Types of Exercise in Later Life: How to maintain strength, balance, & independence in aging.
- Eat a “healthier diet.”
- The exact components of a healthy diet can be debated, but the general principles as articulated by Michael Pollan are pretty sound: “Eat real food. Not too much. Mostly plants.” The components that I believe are most important include:
- Eat lots of vegetables, greens, fruits, whole grains, beans, and lentils.
- Such plant foods provide crucial fiber, vitamins, and minerals.
- Eating them has also been associated with a healthier microbiome (the good bacteria in the gut, which we are realizing play a key role in managing the immune system and inflammation).
- For vegetables, emphasize non-starchy ones (potatoes don’t count!) and try to include several different types, such as leafy greens, cruciferous vegetables (broccoli, cauliflower, etc), orange/red vegetables (carrots, beets).
- Minimize added sugars, fast food, and processed foods, including processed meats.
- Minimize simple starches (e.g. refined flour, most sweets), especially if your bloodwork suggests problems managing blood sugar.
- Eat lots of vegetables, greens, fruits, whole grains, beans, and lentils.
- Research has also suggested that intake of several specific types of foods may be beneficial to older adults. Some to consider include:
- Nuts and seeds (especially flaxseed)
- Foods containing polyphenols, which include olive oil and berries
- Cocoa and tea
- Fish, especially oily fish, which contains omega-3 fatty acids. (Randomized control trial data of fish oil supplements often does not find much effect, so supplements may not be as effective.)
- People with high blood pressure often benefit from a diet lower in sodium.
- Research suggests that a person’s response to diet is highly individual.
- Before persisting with a certain dietary plan, it may be good to ask your clinicians for help determining whether your body is responding well to a certain diet.
- Bonus benefits:
- A healthier diet often is associated with benefits beyond cardiovascular health. These may include improved mood, increased energy, easier weight loss, decreased constipation, and more.
- Diets proven to improve cardiovascular risk factors include the Mediterranean diet and the DASH (Dietary Approach to Stop Hypertension) diet. There is also a newer diet called the MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay), which is basically a combo of the Mediterranean & DASH diets. Learn more here:
- The exact components of a healthy diet can be debated, but the general principles as articulated by Michael Pollan are pretty sound: “Eat real food. Not too much. Mostly plants.” The components that I believe are most important include:
- Seek out and maintain social connections and purpose.
- Relationships, purpose, and feeling that one is contributing help older adults feel their best, and are also associated with better health outcomes.
- For those older adults who feel lonely, have few social connections, and/or feel they may not have enough purpose, options include:
- Making an effort to reconnect or improve connections with family and friends.
- Seeking work or volunteering opportunities.
- Signing up for an exercise class, educational activity, or other activity, whether designed for older adults or for the general public.
- Participating in activities at one’s local center for older adults.
- Considering relocation to a more supportive community or environment, if one is often physically isolated due to transportation issues or the location of one’s home.
- Joining a support group.
- Identifying a cause or project to work on.
- Participating in a local church or spiritual community.
- Be sure to talk to a doctor or other clinician, if physical or mental health symptoms are interfering with the ability to participate in activities.
- Mental health symptoms such as frequent sadness or lack of interest in things may be a sign of depression, and should be evaluated.
- Difficulties with memory or thinking should also be medically evaluated.
- Bonus benefits:
- Social connections and maintaining purpose are key factors in maintaining a sense of well-being in late-life.
- For more on addressing loneliness or social isolation, see the resources listed here: Addressing Loneliness in Aging.
- Use non-drug methods to manage stress, anxiety, and insomnia.
- Several different methods can be used to manage the mind and one’s mental state.
- It is often a good idea to use them in combination.
- Clinicians and other experts can help you determine which combination is best for whatever mind problem is most troublesome to you.
- Methods to consider include:
- Cognitive behavioral therapy, which has been shown to be effective to treat insomnia, stress, and anxiety issues, and also exists in online formats
- Mindfulness-based stress reduction
- Exercise
- Relaxation therapies
- Spiritual practices
- Activities that increase feelings of social connection and purpose
- Various forms of meditation
- Increased time outdoors and in nature
- Musical activities
- Skills and support programs, especially if one’s stress is related to caregiving, chronic illness, or another specific type of life challenge
- Various forms of psychotherapy
- Older adults with sleep problems should be properly evaluated for underlying medical problems, as these are common and may require treatment directed at these problems. For more, see 5 Top Causes of Sleep Problems in Aging, & Proven Ways to Treat Insomnia.
- Bonus benefits:
- Most of the methods above are generally associated with better overall well-being and health.
- Most medications — whether prescription or over-the-counter — used to treat anxiety, stress, or insomnia affect brain function and balance in older adults. Learning to manage these common problems without medication can reduce fall risk and help preserve brain function.
- Several different methods can be used to manage the mind and one’s mental state.
My bottom line on managing cardiovascular risk factors for better brain health
You’ve probably already noticed: my top five recommendations for addressing cardiovascular risk factors are all “healthy lifestyle” basics:
- Don’t smoke
- Get plenty of exercise
- Eat a healthier diet
- Seek out and maintain social connections and purpose
- Use non-drug methods to manage stress, anxiety, and insomnia
Most people are well aware of numbers 1, 2, 3, 4, and some have also heard of the various “lifestyle” approaches to managing stress and insomnia.
But far too few people are trying to put these in action. Which is a shame, because in many cases these approaches work as well as medications do. But they are better, because they bring on lots of bonus benefits. And they are safer, because they can enable older adults to manage cardiovascular risks and other aspects of health with fewer drugs.
See and care for the forest before getting too focused on the trees
As geriatricians, we always try to see and care for “the forest” before getting too focused on “the trees.”
Don’t make the mistake that many people make. Yes, you can try to tinker with each cardiovascular risk factor one at a time. And yes, there are plenty of health providers out there who will offer you lots of testing, and probably some prescription medications.
There is certainly a role for such tests and medications. But before you go too far along that route, remember that it’s always worthwhile to start with healthy, holistic approaches to taking care of one’s physical and mental health.
That is usually what is best and most effective, for the brain, the heart, and the aging body.
This article was first published in 2018, and was last reviewed by Dr. K in May 2024.Â
Prudence Brown says
I really appreciate reading Dr. K’s newsletter and taking advantage of her wise counsel. But one issue that she has yet to address is LOW blood pressure. I am a 76 year old woman diagnosed with mild cognitive impairment due to “mild to moderate small vessel ischemic changes”. I have excellent health otherwise–low cholesterol, lots of exercise, healthy eating, etc. but have had low blood pressure for many years (mostly under 110/75 but not infrequently under 100/75). My doctor hypothesizes that my low bp is contributing to microvascular disease, not enough blood flow to the brain. What does the research say about low bp’s contribution to vascular dementia? Do you ever recommend strategies for increasing, rather than decreasing, bp? Thanks very much.
Nicole Didyk, MD says
That’s an interesting question with a somewhat complicated answer!
I found this article, which is a pretty recent review of the topic, in case you’re comfortable reading scientific articles: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3002634/
What I took away from this is that in general. high blood pressure is associated with an increased risk of dementia, both Alzheimer’s disease (AD) and vascular dementia (VaD).
There is some concern that a lower diastolic blood pressure (the bottom number of a blood pressure reading, so “75” if your BP is 110/75) may increase the risk of dementia, in those who are:
– taking blood pressure medications
– in the “older old” category (aged 85 and up)
This suggests that over treating blood pressure may be the risk factor, rather than someone who naturally runs a lower BP.
If I have a patient with a lower blood pressure, with no symptoms of dizziness, lightheadedness, or falls, I don’t suggest trying to increase the blood pressure. I would simply monitor.
If a person has symptomatic low blood pressure, that’s not due to an infection or other urgency, we suggest:
– maintain a good fluid intake (read more here: https://betterhealthwhileaging.net/qa-how-to-prevent-diagnose-treat-dehydration-aging-adults/)
– use more salt in your diet
– consider support stockings
