High blood pressure, or hypertension, is a major risk factor for strokes. It can weaken and damage the walls of blood vessels, making it easier for clots to form or arteries to rupture in the brain. However, some individuals with normal blood pressure can also experience strokes. While it is uncommon, low blood pressure has been linked to an increased risk of stroke and a higher risk of dying from a stroke. Scientists are still unsure why this link exists.

High blood pressure weakens blood vessels, making them more prone to ruptures and clots
High blood pressure, or hypertension, is a major risk factor for strokes. It is caused when the force of blood pushing against the walls of blood vessels is too high. This can lead to vessel damage, making them more susceptible to ruptures and clots.
Over time, high blood pressure can weaken and damage blood vessel walls, making it easier for clots to form and arteries to rupture. This damage can cause tiny tears in the blood vessels, which the body will attempt to repair by sending special cells to the site. Substances such as cholesterol and fats may also accumulate at these damaged spots, forming plaque and contributing to a process called atherosclerosis. Atherosclerosis causes a narrowing of the arteries, further increasing blood pressure.
The elevated pressure can increase the risk of stroke in two ways. Firstly, it can cause the blood vessels to become less flexible and more vulnerable to blood clot formation. When a clot lodges in an artery supplying blood to the brain, it can result in an ischemic stroke, the most common type of stroke. Secondly, high blood pressure can weaken blood vessels, making them more prone to ruptures. When this occurs in the brain, it is known as a hemorrhagic stroke.
While high blood pressure is a significant risk factor for strokes, it is important to note that low blood pressure has also been linked to an increased risk of stroke. Studies have found that people with low blood pressure have a higher risk of dying from a stroke. Additionally, low blood pressure can lead to complications such as gastrointestinal bleeding and sepsis.

Chronically low blood pressure also raises the risk of stroke
While high blood pressure is a well-known risk factor for strokes, chronically low blood pressure can also increase the risk of stroke and the risk of dying from stroke. This is known as hypotension, which is when blood pressure is less than 90/60 mm Hg.
Scientists are still learning about the relationship between low blood pressure and stroke, but it is clear that there is a link. For example, a 2021 study found that people with systolic blood pressure below 120 mm Hg and at least one other health risk factor were at the highest risk of dying from stroke. Orthostatic hypotension, which is low blood pressure that occurs when a person stands up, has also been linked with an increased risk of ischemic stroke.
In addition to raising the risk of stroke, low blood pressure may also increase the risk of in-hospital complications after a stroke, such as gastrointestinal bleeding and sepsis. It can also cause falls and, in severe cases, shock.
If you are experiencing any symptoms of low blood pressure, such as dizziness or lightheadedness, it is important to consult a healthcare professional.

High blood pressure is called the silent killer because it seldom presents with symptoms
High blood pressure, also known as hypertension, is a major risk factor for stroke. It is often referred to as the "silent killer" because it seldom presents with any symptoms. It is a dangerous condition that can go undetected for a long time and lead to serious health issues, including death.
The condition develops when the force of blood flowing through the blood vessels is consistently too high, causing damage to the blood vessels and organs over time. High blood pressure can lead to clogged arteries, which can cause an ischemic stroke, the most common type of stroke. It can also weaken blood vessels, making them more prone to rupturing and causing a hemorrhagic stroke.
The risk of high blood pressure increases with age, as blood vessels gradually lose their elasticity. However, due to the obesity epidemic, more and more children are also developing high blood pressure. Additionally, certain racial and ethnic groups, such as Black, Hispanic, and Asian adults, particularly males, have higher rates of high blood pressure due to historical, cultural, and dietary factors.
The only way to know if you have high blood pressure is to get it checked regularly. Early detection is crucial, as high blood pressure can lead to serious health complications, including heart disease, heart failure, kidney failure, and stroke. Treatment often involves lifestyle changes, such as improving diet, losing weight, reducing alcohol consumption, and increasing physical activity, as well as medication in some cases.
While high blood pressure is a significant concern, it is important to note that low blood pressure can also increase the risk of stroke. Studies have shown a link between low blood pressure and an elevated risk of stroke and dying from stroke. However, the relationship between the two is still being studied, and scientists are not yet sure why low blood pressure raises the risk.

A healthy blood pressure range is considered to be below 120/80 mm Hg
While it is uncommon, it is possible to have a stroke with normal blood pressure. Typically, high blood pressure, or hypertension, is a major risk factor for strokes. This is because high blood pressure can weaken and damage the walls of your blood vessels, making it easier for a clot to form or an artery to rupture in your brain. However, low blood pressure has also been linked to an increased risk of stroke.
Blood pressure is the force your blood exerts against the walls of your arteries as your heart beats. It is measured in two numbers: systolic and diastolic. These numbers represent the pressure in your arteries when your heart beats and when it rests between beats, respectively. The systolic number is always listed first, followed by the diastolic number. For example, a blood pressure reading of 120/80 mm Hg would be considered healthy.
Maintaining a healthy blood pressure range is crucial for lowering your risk of stroke. Even if your blood pressure is within a healthy range, it is still important to stick with heart-healthy habits such as following a balanced diet and getting regular exercise. Additionally, it is important to check your blood pressure regularly, as it can change over time.
While having a stroke with normal blood pressure is less common, it is still possible. If you or someone nearby begins to show symptoms of a stroke, seek immediate medical attention.

High blood pressure can be lowered through lifestyle changes and medication
High blood pressure, or hypertension, is a major risk factor for strokes. It is often called a "silent killer" because it usually has no symptoms. Over time, it quietly damages blood vessels, making it easier for blood clots to form or for arteries to rupture. This damage can lead to serious health problems, including heart disease, heart failure, stroke, kidney damage, vision loss, memory loss, and cognitive decline.
The good news is that high blood pressure can be lowered through lifestyle changes and medication. Here are some strategies to lower your blood pressure and reduce your risk of stroke:
Lifestyle Changes
- Eat a well-balanced diet: A heart-healthy diet can help lower blood pressure. This includes eating less sodium (under 1,500 mg per day) and more potassium. The Mediterranean diet and the DASH diet are recommended.
- Lose weight: Losing weight, especially belly fat, can improve artery function and help lower blood pressure.
- Exercise regularly: Physical activity can be as beneficial to your heart as medication. Aim for at least 150 minutes a week of moderate-intensity aerobic activity.
- Manage stress: Prolonged stress can raise and maintain high blood pressure. Practices like yoga can help relax your mind, body, and blood pressure.
- Quit smoking: Smoking is a treatable risk factor for high blood pressure.
- Reduce alcohol consumption: Excessive alcohol intake is a risk factor for both ischemic and hemorrhagic strokes.
- Get enough sleep: Aim for 7-9 hours of sleep regularly to help manage blood pressure.
Medication
If lifestyle changes are not enough to lower your blood pressure, your doctor may prescribe medication as part of your treatment plan. Common types of blood pressure medications include angiotensin II receptor blockers (ARBs) and calcium channel blockers.
It's important to work with your healthcare professional to manage your blood pressure and make healthy changes that matter.
