[|AI|]  Hi. Thanks for writing us on Chat Doctor. This could be due to insufficient blood reaching to brain(due to partial obstruction in the carotid artery supplying the brain) or due to problems(related to balance) in inner ear. Can also be due to low blood pressure(orthostatic hypotension) or due to low blood sugars. This might require a through medical evaluation and I suggest taking an appointment and meet a physician. You may need a scan (carotid Doppler). You will get well soon. Hope this helps.
