Preventative measures for dizziness vary depending on the underlying condition causing the dizziness, but options include abstaining from alcohol, salt, tobacco and caffeine; speaking to a doctor about discontinuing or lowering the dose of a medication; drinking plenty of fluids; and following a healthy diet. Getting enough sleep and keeping stress at bay may also prevent dizziness, as stated by Mayo Clinic.
A doctor may be able to prevent or treat dizziness caused by some types of vertigo by performing head-positioning maneuvers, notes Mayo Clinic. If the dizziness is caused by an inner ear condition such as vestibular neuritis, a doctor may teach exercises that decrease sensitivity to motion. Psychotherapy can be an effective preventative measure if the dizziness is caused by an anxiety disorder.
A doctor may prescribe a medication to prevent dizziness, according to Mayo Clinic. Options include water pills, anti-nausea medications, anti-anxiety medications and migraine medications. Anticholinergics may reduce dizziness, and some types of antihistamines may reduce the symptoms of vertigo for a short period of time.
If the dizziness is caused by overheating or dehydration, it can be alleviated by drinking a sports drink and resting in a cool area, recommends Mayo Clinic. Dizziness usually goes away naturally, but severe episodes of vertigo may be relieved by sitting in a dark room with closed eyes. Sitting or lying down as soon as a dizzy spell occurs may provide relief.
