Various diseases, disorders and conditions can cause a loss of balance, explains Healthline. For example, inner ear infections and inflammations resulting from the flu or an upper respiratory infection can make patients dizzy or unsteady. In addition, head injuries, strenuous physical activity and atmospheric pressure changes can also contribute to a loss of balance.
One common type of balance disorder is benign paroxysmal positional vertigo, states NIHSeniorHealth. Benign paroxysmal positional vertigo causes a short, but intense instance of vertigo after changing the position of the head. This disorder causes small calcium deposits in the inner ear to become displaced and throw off balance. The exact cause for this disorder is unknown as of 2015.
Ménière's disease is another condition that can cause loss of balance, states NIHSeniorHealth. Symptoms of Ménière's disease include vertigo, hearing loss, tinnitus and a full feeling in the ear.
Although ear conditions are often responsible for balance issues, poor blood circulation, chemical imbalances in the brain, high and low blood pressure and arthritis can also trigger loss of balance, states Heathline. In addition, certain medications can affect balance. Because balance issues can have multiple causes, a doctor can conduct blood tests, hearing exams, eye movement tests and brain imaging to find the root cause of the loss of balance.
