Orthostatic Hypotension

Orthostatic hypotension (also called postural hypotension) is a sudden drop in blood pressure that happens when a person stands up from sitting or lying down. It causes brief dizziness, lightheadedness, blurred vision, or unsteadiness — and in seniors it is a common, often overlooked cause of falls.

Why it happens

With age, the body's blood-pressure reflexes slow down. Dehydration, certain medications (especially blood-pressure drugs and diuretics), prolonged bed rest, and some medical conditions can all trigger or worsen it.

Managing it to prevent falls

Practical steps include standing up slowly — sit on the edge of the bed for a moment, then rise gradually — staying well hydrated, and having a stable handhold like a grab bar, bed rail, or cane nearby when getting up. Because it is often medication-related, anyone with frequent dizziness on standing should have their medications reviewed by a doctor. Addressing it is an important part of fall prevention.
