Postural hypotension

Postural Hypotension (also known as 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.

Causes[edit | edit source]

Postural 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 postural hypotension, particularly drugs used to treat high blood pressure — diuretics, beta blockers, calcium channel blockers and angiotensin-converting enzyme (ACE) inhibitors — as well as antidepressants and drugs used to treat Parkinson's disease and erectile dysfunction.

Symptoms[edit | edit source]

Symptoms of postural hypotension include dizziness or lightheadedness, fainting (syncope), blurred vision, weakness, fatigue, nausea, cold, clammy, pale skin, rapid, shallow breathing, and confusion.

Diagnosis[edit | edit source]

Diagnosis of postural hypotension is made by a simple test that checks the blood pressure while the patient is lying down, sitting, and standing. The doctor may also check the patient's blood pressure after the patient has been standing for 2 to 5 minutes.

Treatment[edit | edit source]

Treatment of postural hypotension depends on the cause. If it's caused by medication, your doctor may change the dose or switch you to another medication. If it's due to a non-drug-related cause, treatment may involve lifestyle modifications, such as drinking plenty of fluids and avoiding alcohol.
