Low blood pressure, also known as hypotension, is diagnosed when the blood pressure is so low that it does not deliver enough blood to the body's organs and may cause symptoms and side effects that are potentially dangerous.
Being dizzy, light-headed and even fainting, can all be side effects that show up with low blood pressure. These side effects may be most noticeable when standing up after sitting or lying down.
Low blood pressure can cause heart attacks in some people.
Having low blood pressure can raise the risk of stroke, which can lead to brain and nerve damage.
Low blood pressure can cause kidneys to fail to eliminate bodily wastes, resulting in a buildup of toxins.
Sometimes the lack of blood flow that occurs with low blood pressure can cause a person to go into shock, a condition in which organs quickly begin to fail.
