3 AnswersLow blood pressure, or hypotension (blood pressure less than 90/60), can be caused by the following: pregnancy; hormonal problems such as underactive/hyperactive thyroid, diabetes, or low blood sugar; over-the-counter medications; overdose of high blood pressure medications; heart failures; abnormal heart rhythm; widening of blood vessels; heat exhaustion; or liver disease.

1 AnswerThe best treatment for low blood pressure depends on the cause. If blood pressure is low due to blood loss then the best treatment would be replacement of fluids either via transfusion or infusion of fluids. Low blood pressure can also be treated with the following: increasing salt intake; increasing fluid intake; taking medications to raise blood pressure; or wearing compression stockings to increase blood return from the lower extremities, decreasing swelling and pooling of blood in the legs.

Another name for low blood pressure is hypotension. Some people have hypotension all the time. These people have no problems with the low blood pressure and it is considered to be normal for them.
Low blood pressure may be a concern to your doctor if you begin to have symptoms such as feeling dizzy, anemia, dehydration, abnormal heartbeats or fainting. Sometimes very low blood pressure can cause shock, a serious condition that needs immediate medical attention. Your doctor will test for further problems to see what might be causing the low blood pressure readings and other symptoms.

A primary care doctor or specialist may diagnose and treat hypotension. The type of specialist most commonly involved is a cardiologist (heart specialist).
Other specialists also may be involved, such as surgeons, nephrologists (kidney specialists), neurologists (brain and nerve specialists), or others.

1 AnswerPiedmont Heart Institute answeredHypotension can affect people of all ages. However, people in certain age groups are more likely to have certain types of low blood pressure.
Older adults are more likely to have orthostatic and postprandial hypotension. Children and young adults are more likely to have neurally mediated hypotension.
People who become dehydrated or volume depleted due to many reasons are at risk for hypotension.
People who take certain medicines, such as high blood pressure medicines, are at higher risk for low blood pressure. People who have central nervous system disorders (such as Parkinson's disease) or some heart conditions also are at higher risk for low blood pressure.
Other risk factors for hypotension include being immobile (not being able to move around very much) for long periods and pregnancy. Hypotension during pregnancy is normal and goes away after birth.

Doctors often can successfully treat hypotension. Many people who have the disorder live normal, healthy lives.
If you have low blood pressure, you can take steps to prevent or limit symptoms, such as dizzy spells and fainting.
If you have orthostatic hypotension, get up slowly after sitting or lying down. Eat small, low-carbohydrate meals if you have postprandial hypotension (a form of orthostatic hypotension).
If you have neurally mediated hypotension, don't stand for long periods. Also, drink plenty of fluids and try to avoid unpleasant or scary situations. Learn to recognize symptoms and take action to raise your blood pressure. Children who have NMH often outgrow it.
Other lifestyle changes also can help you control low blood pressure.
Ask your doctor about learning how to measure your own blood pressure. This will help you find out what a normal blood pressure reading is for you. Keeping a record of blood pressure readings done by health professionals also can help you learn more about your blood pressure.

1 AnswerPiedmont Heart Institute answeredHypotension is low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood.
Blood pressure is measured as systolic and diastolic pressures. Systolic blood pressure is the pressure when the heart beats while pumping blood. Diastolic blood pressure is the pressure when the heart is at rest between beats.
You will most often see blood pressure numbers written with the systolic number above or before the diastolic, such as 120/80 mmHg. (The mmHg is millimeters of mercury-the units used to measure blood pressure.)
mal blood pressure in adults is lower than 120/80 mmHg. Hypotension is blood pressure lower than 90/60 mmHg.

1 AnswerPiedmont Heart Institute answered
There are several types of hypotension. People who always have low blood pressure have chronic asymptomatic hypotension. They have no signs or symptoms and need no treatment. Their low blood pressure is normal for them.
The three main types of this kind of hypotension are orthostatic hypotension, neurally mediated hypotension (NMH), and severe hypotension linked to shock.
Orthostatic hypotension
This type of low blood pressure occurs when standing up from a sitting or lying down position. It can make you feel dizzy or lightheaded, or even make you faint.
Orthostatic hypotension occurs if your body isn't able to adjust blood pressure and blood flow fast enough for the change in position. This type of low blood pressure usually lasts for only a few seconds or minutes after you stand up. You may need to sit or lie down for a short time while your blood pressure returns to normal.
Orthostatic hypotension can occur in all age groups. However, it's more common in older adults, especially those who are frail or in poor health. It can be a symptom of other medical conditions, and treatment often focuses on treating the underlying condition(s).
Neurally mediated hypotension
With NMH, blood pressure drops after you've been standing for a long time. You may feel dizzy, faint, or sick to the stomach as a result. This type of low blood pressure also can occur if you have an unpleasant, upsetting, or scary experience.
Severe Hypotension Linked to Shock
People may say a person has "gone into shock" as a result of an upsetting event. But to doctors, the word "shock" has a different meaning. This implies collapse of the cardiovascular system from a variety of reasons.

1 AnswerPiedmont Heart Institute answeredWhen orthostatic hypotension is caused by hypovolemia due to medication, the disorder may be reversed by adjusting the dosage or discontinuing the medication. When the condition is caused by prolonged bed rest, improvement may occur by sitting up with increasing frequency each day. In some cases, physical counter-pressure such as an elastic hose or a whole-body inflatable suit may be required. Dehydration is treated with salt and fluids.

1 AnswerPiedmont Heart Institute answered
Treatment depends on the type of hypotension you have and how severe your signs and symptoms are. The goals of treatment are to relieve signs and symptoms and manage any underlying condition(s) causing the hypotension. Your response to treatment depends on your age, overall health, and strength. It also depends on how easily you can stop, start, or change medicines. In a healthy person, low blood pressure without signs or symptoms usually needs no treatment. If you have signs or symptoms of low blood pressure, you should sit or lie down right away. Put your feet above the level of your heart. If your symptoms don't go away quickly, you should seek medical care right away.
Orthostatic Hypotension
There are a number of treatments for orthostatic hypotension. If you have this type of low blood pressure, your doctor may advise making lifestyle changes such as:- Drinking plenty of fluids, like water
- Drinking little or no alcohol
- Standing up slowly
- Not crossing your legs while sitting
- Gradually sitting up for longer periods if you've been immobile (not able to move around much) for a long time due to a medical condition
- Eating small, low-carbohydrate meals if you have postprandial hypotension (a form of orthostatic hypotension)
