Gets dizzy every time I raise my arm.
Hello, I am a 34-year-old male that gets dizzy spells when I raise my arm above my head or change body positioning while sleeping or standing up!! All of it makes me have dizzy spells!! What could it be? Can anyone tell me what might be causing it?
@nnie Hello, the cause of dizziness while raising your arm or changing positions is orthostatic hypotension. Orthostatic hypotension occurs when a person rises to a standing position from a lying or sitting position and is a result of falling blood pressure of 20 mm Hg systolic or 10 mm Hg diastolic with or without an increase in pulse rate. The symptoms typically include dizziness, light-headedness, temporary blindness, body dissociation, extremity tingling, or even fainting. These symptoms are a result of insufficient blood flow to the brain. Common causes of orthostatic hypotension include volume depletion, neurologic abnormalities, and medication. If raising your arms causes you dizziness, you should be evaluated by a doctor for a physical exam – especially if you can consistently replicate the symptoms. Commonly, compression of the large blood vessels in the neck/upper thorax can produce a dizzy sensation. However, rarely, tumors of the upper thorax can produce numbness/weakness of a limb as well as dizziness upon raising the arms.
