What does WebMD say about dizziness when standing?

WebMD-style guidance on dizziness when standing is usually about orthostatic hypotension, also called postural hypotension — a brief drop in blood pressure when you stand up from sitting or lying down. That can make you feel lightheaded, woozy, or like you might faint.

Common causes can include:

• Dehydration or not drinking enough fluids
• Medications, especially some blood pressure medicines, antidepressants, and other drugs that can lower blood pressure
• Heart problems that affect how well blood is pumped
• Nervous system or autonomic disorders such as Parkinson’s disease
• Other contributors like older age, pregnancy, prolonged bed rest, alcohol use, or standing up too quickly

What often helps:

• Stand up slowly, especially after lying down
• Drink enough fluids
• Avoid overheating, such as very hot baths or showers
• Review medications with a clinician if this happens often

Get medical help promptly if dizziness comes with fainting, chest pain, shortness of breath, sudden weakness, numbness, confusion, or a severe headache.
