How to Measure Orthostatic Hypertension

Orthostatic hypotension refers to a sudden drop in blood pressure that occurs when a person stands up from a lying position. This can lead to symptoms such as dizziness, unsteadiness, and even falls due to reduced blood flow to the brain. To properly assess this condition, a patient should first lie down for at least five minutes before their blood pressure is measured.

The Measurement Process

After the initial reading while lying down, the patient should stand up, and their blood pressure should be measured again at one minute and five minutes after standing. This method allows healthcare providers to observe how the body responds to changes in posture.

Diagnostic Criteria

A diagnosis of orthostatic hypotension is typically made if the systolic blood pressure drops by at least 20 mmHg or the diastolic pressure decreases by 10 mmHg when standing compared to the lying position. This condition is commonly seen in both children and older adults, although it can occur at any age.

Medications That May Contribute to Orthostatic Hypotension

Certain medications, particularly alpha-blockers, can increase the risk of experiencing orthostatic hypotension. These drugs are often prescribed for conditions such as high blood pressure or prostate issues. To minimize the risk of symptoms, it is generally recommended that these medications be taken at night before bedtime.
