People lose their balance due to ear infections, trauma, tumors, conditions such as low blood pressure or problems with the visual or skeletal systems, according to MedicineNet. Medications can also affect a person's balance.
One type of ear infection that can affect a person's balance is called labyrinthitis, states MedicineNet. Specifically, the inner ear is infected or inflamed. People sometimes get labyrinthitis when they have the flu or some other malady of the upper respiratory system.
Orthostatic or postural hypotension can also affect a person's balance, explains Mayo Clinic. It causes a person to feel dizzy after he stands up from a sitting or lying position too suddenly. This happens to many people, and mild cases of postural hypotension are not causes for concern. However, a person should see his doctor if it happens frequently. It can be a sign of a heart condition or problems with the thyroid, adrenal glands or the nervous system.
Brain tumors can also cause a person to lose his balance, notes WebMD. This is true whether the tumor is benign or malignant. A stroke can also interfere with a person's balance, according to MedlinePlus. It is important to seek emergency medical care if a person experiences difficulties in balance or other symptoms, as therapies exist to stop a stroke even when it is happening.
