Orthostatic hypotension is a condition of abnormal blood pressure regulation upon standing. The blood pressure quickly decreases, more than 20/10 mm Hg, when rising from a lying down or sitting position to a standing position.
When standing, blood falls toward the lower body in response to gravity. To help keep blood in the upper body:
Blood pressure is also affected by the amount of blood in the blood vessels. Low levels of blood will decrease the blood pressure and make it harder for the body to compensate when standing. Low blood volume, called hypovolemia, is the most common cause of orthostatic hypotension. It may be due to:
Orthostatic hypotension will occur when 1 or more of these factors do not work as expected. It may be associated with:
Factors that increase your chance of orthostatic hypotension include:
Orthostatic hypotension may cause:
Exercise or having eaten a heavy meal may worsen symptoms.
Orthostatic hypotension is diagnosed when symptoms are present and there is a measured reduction in blood pressure while standing, which is relieved by lying down.
When possible, treatment will focus on resolving the orthostatic hypotension completely. If a complete resolution is not possible, treatment will focus on managing symptoms.
Treatment will depend on the cause. Examples include:
Common approaches include:
The doctor may recommend prescription medications to increase blood pressure.
Dietary changes may also help increase blood pressure or prevent very low blood pressure. A dietitian may help create a diet plan. Steps may include:
Behavioral changes that may help include:
There is no way to prevent orthostatic hypotension if it is a result of other diseases or conditions. However, if orthostatic hypotension relates to medications, dehydration, or bedrest, talk with a healthcare provider about treatment options.
