Treatment:

Hypotension in a healthy person that does not cause any problems usually doesn't require treatment.

If you have signs or symptoms of low blood pressure, you may need treatment. Treatment depends on the cause of your low blood pressure. Severe hypotension caused by shock is a medical emergency. You may be given blood through a needle (IV), medicines to increase blood pressure and improve heart strength, and other medicines, such as antibiotics. For more details, see the article on shock.

If you have orthostatic hypotension caused by medicines, your doctor may change the dose or switch you to a different drug. DO NOT stop taking any medicine before talking to your doctor. Other treatments for orthostatic hypotension include increasing fluids to treat dehydration or wearing elastic hose to boost blood pressure in the lower part of the body.

Those with NMH should avoid triggers, such as standing for a long period of time. Other treatments involve drinking plenty of fluids and increasing the amount of salt in your diet. (Ask your doctor about specific recommendations.) In severe cases, medicines such as fludrocortisone may be prescribed.

Expectations (prognosis):

Low blood pressure can usually be treated with success.

Complications:

• Shock
• Injury from falls due to fainting

Falls are particularly dangerous for older adults. Fall-related injuries, such as a broken hip, can dramatically impact a person's quality of life.

Severe hypotension starves your body of oxygen, which can damage the heart, brain, and other organs. This type of hypotension can be life threatening if not immediately treated.

Calling your health care provider:

When you have symptoms from a drop in blood pressure, you should immediately sit or lie down and raise your feet above heart level.

If low blood pressure causes a person to pass out (become unconscious), seek immediate medical treatment or call the local emergency number (such as 911). If the person is not breathing or has no pulse, begin CPR.

Call your doctor immediately if you have any of the following symptoms:

• Black or maroon stools
• Chest pain
• Dizziness, lightheadedness
• Fainting
• Fever higher than 101 degrees Fahrenheit
• Irregular heartbeat
• Shortness of breath

Also call your doctor if you have:

• Burning with urination or other urinary symptoms
• Cough with phlegm
• Inability to eat or drink
• Prolonged diarrhea or vomiting
