• Certain physical conditions - such as orthostatic hypotension. Orthostatic hypotension is often a result of a disease state, or dehydration may also cause dizziness symptoms.
• As you get older, or as a result of certain conditions, the central nervous system has a more difficult time regulating blood pressure levels. When you change from a lying to a standing position rapidly, you may feel "faint" or lightheaded, as your blood pressure drops to a level below normal.
• Orthostatic hypotension may also occur if you are anemic, or dehydrated, as the fluid volume levels in your body are low.
• Medications - If you are taking certain medications to control your high blood pressure or heart rate, for example, these may cause your blood pressure to become low.

How Is Dizziness Diagnosed?

• Usually, your healthcare provider will first take a complete health history from you. They will then examine your neurological system through conducting a physical exam in their office. This may include looking in your eyes, watching you stand or walk, and testing your strength. He or she will also look inside your inner ear, to see if there is an infection.
• To distinguish vertigo from dizziness, your healthcare provider may turn your head in different positions, usually from a sitting position, to a lying position, and back again, as they try to elicit the same dizziness symptoms that you are describing.
• Your healthcare provider may suggest that you have x-rays, an MRI, or a CAT scan of your head. You may also be referred to a neurologist, who specializes in dizziness disorders.

Symptom Management:

• It is important to notify your healthcare provider if you notice any dizziness, or any change in the pattern of dizziness symptoms you are experiencing. Also, notify your healthcare provider if you have any loss of vision, hearing, or if your symptoms become more severe, and do not improve.
• If low blood pressure is a symptom contributing to your dizziness and you are taking medications to control high blood pressure, talk with your doctor about whether your medication may need to be adjusted.
• Drink 2-3 liters of fluid per day to prevent dehydration. This may include fruit juices, water, non-caffeinated sodas and coffee, and non-alcoholic beverages. Alcohol and caffeine may cause dehydration, so these should be avoided. Always carry a "sipper" cup filled with your favorite drinks.
• Change positions slowly to avoid vertigo and/or dizziness. Allow your body a chance to adapt to the position change. For some people, lying down until the dizzy episode passes may be the best solution.
• With moderate dizziness, walk slowly and often. Walk with assistance if the dizziness is severe.
• If you have vertigo, your doctor or a trained therapist may teach you exercises, called "vestibular exercises," to try to get rid of your dizziness. Vertigo improvement exercises involve you sitting down, and changing into different positions. This may increase your dizziness at first, while you are performing these movements, but should help to correct the vertigo. You may expect improvement in 2-6 months.
• If you have Meniere's disease (a disease of the inner ear), treatment of this condition may include:
  • Limiting the amount of salt you eat in a day
  • Prescription of anti-nausea
  • Anti-vertigo medications
  • And/or medication to help your body rid itself of salt and fluids (a diuretic). The goal is to decrease the pressure of your inner ear, in an effort to control the vertigo.
• Depending on the cause of dizziness, vertigo and/or other symptoms it may last a few days to a few months. It is important to follow all the instructions from your healthcare provider.
