An infection or inflammation of the inner ear is one of the most common reasons for loss of balance, according to the National Institute on Deafness and Other Communication Disorders. This condition is known as labyrinthitis, and it is often associated with upper respiratory infections.

Conditions such as stroke, arthritis and chemical imbalance in the brain may cause loss of balance and dizziness, according to Healthline. Smoking and diabetes can increase a person's risk of stroke. Low blood pressure also causes loss of balance.

Some medications lower blood pressure and cause loss of balance, explains NIH Senior Health. Ototoxic drugs may damage the inner ear and cause loss of balance. This side effect may last as long as the patient takes the drug, but sometimes it is permanent. Groups of drugs that are likely to be ototoxic include antidepressants, anticonvulsants, sedatives, tranquilizers and diuretics. Other ototoxic drugs include hypertensive medications, aminoglycosides, vasodilators and certain anti-cancer drugs.
