Dizziness
Alternate Names : Dizzy, Lightheadedness
How is the symptom diagnosed?
Diagnosing the cause of dizziness starts with a medical history and physical exam. This
may be all that is needed to figure out the cause. In other cases, further
tests may be needed.
For example, a blood glucose test may be done to look for low blood
sugar. Measuring the blood
pressure can detect low
blood pressure. A special X-ray test, called a cranial CT
scan, may be done if a
stroke or brain
tumor is suspected. A test to measure brain waves, called an
electroencephalogram or EEG, may be done if seizures are suspected. Many
other tests are possible depending on the suspected cause.
