When you're dizzy, you may feel lightheaded, woozy, or disoriented. If you feel like you or the room are spinning, you have vertigo. These feelings may make you lose your balance.

Dizziness can have many different causes. A sudden drop in blood pressure or being dehydrated can make you dizzy. Many people feel lightheaded if they get up too quickly from sitting or lying down. Certain medicines and problems with your inner ear may cause dizziness. So can motion sickness. Sometimes dizziness can be a symptom of other disorders.

As people get older, they may have more health problems and take more medicines. This makes them more likely to have problems with dizziness and balance.

Dizziness usually gets better by itself or is easily treated. If you are dizzy often, you should see your health care provider to find the cause.

A fistula is an abnormal connection between two parts inside of the body. Fistulas may develop between different organs, such as between the esophagus and the windpipe or the bowel and the vagina. They can also develop between two blood vessels, such as between an artery and a vein or between two arteries.

Some people are born with a fistula. Other common causes of fistulas include:

• Complications from surgery
• Injury
• Infection
• Diseases, such as Crohn's disease or ulcerative colitis

Treatment depends on the cause of the fistula, where it is, and how bad it is. Some fistulas will close on their own. In some cases, you may need antibiotics and/or surgery.
