The ear is home to a mazelike structure called the vestibular system, which works with your vision and the muscles throughout the body to keep you upright. That’s why an ear infection or a more serious problem, like a tumor in the ear, can upset this system and give you dizzy spells, says Anh Nguyen-Huynh, M.D., Ph.D., a balance-disorder specialist at Oregon Health & Science University, in Portland.

When this is acute, the brain becomes deprived of oxygen-rich blood, which can make you feel light-headed and, in turn, compromise your spatial awareness, says sports-medicine physician Jordan Metzl.
While any vision loss can affect balance, cataracts (a condition that involves a loss of depth perception in addition to blurriness) can particularly challenge stability, says Nguyen-Huynh.
A loss of sensation on the bottoms of the feet is a common symptom of this chronic disease. When you can’t sense the ground properly, it's easy to get thrown off-balance.
These debilitating headaches can make you overly sensitive to motion, sound, light, and other visual information that your brain and body rely on to maintain balance.
