Dizziness is a very common complaint, especially as one grows older.
There are numerous causes of dizziness. A common cause is getting up too quickly from a sitting position. This is called orthostatic hypotension, where blood pressure drops rapidly as a person stands up. Medications can also cause dizziness. They include such drugs as barbiturates, antihistamines, diuretics, and the antibiotics streptomycin, neomycin, and gentamicin.
