Hi, Thanks for writing in. Our brain has an inbuilt balance mechanism by which we adjust our balance with change in posture. This is done by the cerebellum and the inner ear mechanism. The cerebellum is the small brain and controls the balance and gait centers. The inner ear has the vestibular system that gathers the information regarding change in posture and relays it to the brain. The information in the inner ear is transmitted by the hair cells and endolymph in the inner ear. There are conditions when these hair cells do not function properly with change in position and are unable to send the right information to the brain. This leads to a confusion of the brain in processing the change in position and adapting to it. The result is dizziness and vertigo. It might help to get detailed investigation done under guidance of your doctor. Vertin is a medication that helps send the correct information to the brain and prevent dizziness. Please do not worry.
