Other terms for dizziness: vertigo, woozy, faint, light headed
What is dizziness?
Dizziness is a term used to describe when you are feeling woozy, or faint. Vertigo,
a symptom of dizziness, is the feeling that the room is spinning around you.
When people experience dizziness, it may be a symptom showing the balance mechanism
in your inner ear is not working properly.
- Many medications, treatments, and diseases can cause dizziness. It may also be a
result of injury to your ear.
- Dehydration may lead to feeling of lightheadedness especially when changing positions.
This dizziness symptom is due to low blood pressure.
- 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
Your healthcare provider may order some blood work to be drawn. The blood work will
show many things that could be causing your dizziness symptoms. These include anemia,
checking your blood electrolytes (sodium, potassium, and kidney function) as well
as to evaluate for dehydration.
Things you can do:
- 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.

movements, but should help to correct the vertigo. You may expect improvement in
