Introduction to dizziness (feeling dizzy)
Dizziness is one of the most common symptoms that will prompt a person to seek medical care. The term dizziness is sometimes difficult to understand since it means different things to different people. It is either the sensation of feeling lightheaded as if the individual is weak and will pass out, or it describes vertigo or the sensation of spinning, as if the affected person just got off a merry-go-round.
Lightheadedness is often caused by a decrease in blood supply to the brain, while vertigo may be caused by disturbances of the inner ear and the balance centers of the brain. It is important that the health care provider understand the complaint the person is experiencing. That is the first important step so that the proper direction can be taken to find a diagnosis and begin treatment.
