Which condition is associated with a drop in blood pressure when a person stands or sits up?

• A. Hypotension
• B. Orthostatic Hypotension
• C. Postural Hypertension
• D. Chronic Hypotension

Answer: (B)

Orthostatic hypotension is a condition characterized by a significant drop in blood pressure that occurs when a person moves from a sitting or lying position to an upright position. This drop can lead to symptoms such as dizziness or fainting due to reduced blood flow to the brain. The physiological mechanism behind this condition involves a failure of the body’s normal compensatory responses, which typically constrict blood vessels and increase heart rate to maintain blood pressure when changing positions. In individuals with orthostatic hypotension, this compensatory response is impaired, leading to a rapid decline in blood pressure upon standing or sitting up. This condition is often particularly notable when someone has been lying down for an extended period and then suddenly stands up. Recognizing orthostatic hypotension is crucial, as it can indicate underlying health issues or medication effects, and it requires appropriate management to ensure patient safety and prevent falls.
