Your child’s doctor will first determine whether he or she is suffering from lightheadedness or vertigo, and then figure which underlying condition is causing these episodes. There are many possible factors, ranging from colds and allergies to anxiety, medications, inner ear disorders and migraine headaches. Treatment varies depending on the condition responsible. Often a cold or flu will run its course and symptoms will dissipate after a few days. A change in medication can reduce or eliminate side effects. Other treatment options include physical and occupational therapy, vestibular rehabilitation, lifestyle changes, medications and surgery.
