Orthostatic Hypotension manifests as which event?

• A. No Change In Blood Pressure On Standing
• B. Drop In Blood Pressure Upon Standing
• C. Rise In Blood Pressure Upon Standing
• D. Drop In Blood Pressure Only During Sleep

Answer: (B)

Orthostatic hypotension centers on how blood pressure changes when you move to an upright position. When you stand, gravity pulls blood toward the legs, reducing venous return to the heart. If the body's reflexes (baroreceptors and autonomic responses) don’t compensate quickly enough, blood pressure falls. This is what the condition captures: a drop in blood pressure upon standing. In practical terms, a decrease of about 20 mmHg in systolic pressure or 10 mmHg in diastolic pressure within a few minutes of standing is typical, often with dizziness or lightheadedness. It’s not about no change, nor about a rise, and it isn’t limited to sleep—the key feature is the posture-related drop when standing.
