can low blood pressure cause stroke?
308347
A less common cause of ischemic stroke occurs when blood pressure becomes too low (hypotension), reducing blood flow to the brain. This usually occurs with narrowed or diseased arteries. Low blood pressure can result from a heart attack, large loss of blood or severe infection.

High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities. A stroke can also kill you.

There are different types and causes of low blood pressure. Severe hypotension can be caused by sudden loss of blood (shock), severe infection, heart attack, or severe allergic reaction (anaphylaxis). Orthostatic hypotension is caused by a sudden change in body position.

Low blood pressure can affect other organs leading to shortness of breath, fainting, blacking out, chest pain, and cool, clammy skin.

(Hypotension) Low blood pressure is blood pressure low enough to cause symptoms such as dizziness and fainting. Very low blood pressure can cause damage to organs, a process called shock.

Low blood pressure occurs when blood pressure is much lower than normal. This means the heart, brain, and other parts of the body do not get enough blood. Normal blood pressure is mostly between 90/60 mmHg and 120/80 mmHg. The medical name for low blood pressure is hypotension.

Exercise for people with low blood pressure Exercise — especially exercise that involves sudden changes in posture — can trigger symptoms, including dizziness, blurred vision, and nausea. That doesn't mean you shouldn't exercise if you have low blood pressure.

Low blood pressure - or hypotension- occurs when the force at which the heart pumps blood through the arteries falls. Hypotension can present with various symptoms: from nausea, dizziness to heart palpitations.

Many people with low blood pressure don't have any symptoms. Symptoms to watch for include: Feeling dizzy, light-headed, or faint. Feeling sick to your stomach or vomiting.

Most doctors will only consider chronically low blood pressure as dangerous if it causes noticeable signs and symptoms, such as: Dizziness or lightheadedness. Nausea. Fainting (syncope)

Blood vessels damaged by high blood pressure can narrow, rupture or leak. High blood pressure can also cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke.

Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure.

Low blood pressure has many different causes including: Emotional stress, fear, insecurity or pain (the most common causes of fainting) Dehydration, which reduces blood volume. The body's reaction to heat, which is to shunt blood into the vessels of the skin, leading to dehydration.

Low blood pressure is when your blood pressure falls much lower than is normal for you. You may be a person who has naturally low blood pressure which isn't causing any problems. But if your blood pressure becomes lower than usual for you, it can cause symptoms such as dizziness and fainting.

Low blood pressure might seem desirable, and for some people, it causes no problems. However, for many people, abnormally low blood pressure (hypotension) can cause dizziness and fainting.

Some symptoms occur when the body tries to increase blood pressure that is low. For example, when arterioles constrict, blood flow to the skin, feet, and hands decreases. These areas may become cold and turn blue.
