Dizziness in older adults: BP, sugar or medicines?
Dizziness, lightheadedness, and unsteadiness in seniors are major warning signs that carry a high risk of dangerous falls and hip fractures. Common causes include postural blood pressure drops, multiple conflicting medications (polypharmacy), dehydration, or low blood sugar. Senior Physician Dr. Vishnu Anjan Nareddy provides specialized geriatric reviews in Tirupati.

Common possible causes
Frequently asked questions
Why does my elderly parent feel dizzy when standing up?
As blood vessels age, autonomic reflexes that pump blood upwards upon standing become sluggish (postural hypotension). Blood pressure medications can worsen this if not carefully calibrated.
How can we prevent fall injuries at home?
Have a physician review and simplify medicines, ensure bright lighting at night, remove loose rugs, install bathroom grab bars, and encourage drinking adequate water.
