Orthostatic

Orthostatic hypotension is a form of low blood pressure that happens when you stand up from sitting or lying down. It can make you feel dizzy or lightheaded, and maybe even faint. Orthostatic hypotension may be mild and last for less than a few minutes. However, long-lasting orthostatic hypotension can signal more-serious problems, so it's important to see a doctor if you frequently feel lightheaded when standing up.

Causes

Orthostatic hypotension can occur for various reasons, including dehydration, prolonged bed rest, pregnancy, diabetes, heart problems, burns, excessive heat, large varicose veins and certain neurological disorders.

A number of medications can also cause orthostatic hypotension, particularly drugs used to treat high blood pressure or Parkinson's disease.

Symptoms

The most common symptom is lightheadedness or dizziness when you stand up after sitting or lying down. Symptoms usually last less than a few minutes.

Orthostatic hypotension signs and symptoms include:

• Feeling lightheaded or dizzy after standing up
• Fainting (syncope)
• Blurred vision
• Weakness
• Nausea
• Confusion
• Feeling as if you might pass out

Treatment

Treatment of orthostatic hypotension is guided by the cause. If it's caused by medication, your doctor might change the dose or switch you to another drug. If it's due to a condition such as dehydration or bleeding, addressing that issue might improve orthostatic hypotension.
