Dizziness When Standing Up: Causes, Quick Tips and When to See a Doctor

Why that head rush happens, and how to get up safely.

Quick answer

Feeling dizzy or lightheaded when you stand up is often caused by orthostatic hypotension, a temporary drop in blood pressure as blood pools in the legs. It becomes more common after 50 and can be triggered by dehydration, heat, standing up too quickly, alcohol, certain medications (especially for blood pressure, the prostate or mood) and prolonged bed rest. Inner-ear problems can also cause dizziness with position changes. Rise slowly, sit on the edge of the bed first, drink enough water and review medications with your doctor. Fainting, falls or dizziness with chest pain or neurological symptoms need prompt medical care.

Key takeaways

That brief head rush when you stand up is very common, but it can increase the risk of falls, especially in older adults.

How to stand up safely

Take it in stages

Sit up, wait 30 seconds, sit on the edge of the bed, then stand while holding something sturdy.

Pump your legs

Flex your ankles and squeeze your calves a few times before standing.

Hydrate

Drink water through the day unless your doctor has advised fluid limits.

Review medicines

Ask your doctor or pharmacist whether any of your medications could be causing dizziness.

Supporting your overall balance system also matters. VertiAid is a daily chewable for adults over 50 with vitamin D3, Aquamin® minerals, collagen and active vitamin B6 to support the inner ear and steady balance.

Get medical help if you faint, fall, or have dizziness with chest pain, a racing or irregular heartbeat, severe headache, weakness, numbness or trouble speaking.
