GI series

GI series is a medical testing procedure used to examine the gastrointestinal tract including the esophagus, stomach, and small intestine. The procedure involves the use of a substance called barium and X-rays.

Procedure

The patient is asked to drink a liquid that contains barium. The barium coats the inside of the esophagus, stomach, and small intestines so that they can be seen on an X-ray. For the lower GI series, a barium enema is given. The barium fills and then coats the lining of the lower intestine before X-rays are taken.

Uses

The GI series is used to diagnose problems in the gastrointestinal tract. These problems may include ulcers, tumors, inflammation of the stomach lining, hernias, or blockages. The test may also be used to monitor the progress of treatment for these conditions.

Risks

While the GI series is generally safe, there are some risks associated with the procedure. These include allergic reactions to the barium, constipation caused by the barium, and exposure to radiation from the X-rays.

Preparation

Before the procedure, the patient may be asked to follow a special diet and take laxatives to clean out the intestines. The patient should also inform the doctor of any medications they are taking, as some may interfere with the test results.

Results

The results of the GI series can help the doctor determine the cause of symptoms such as abdominal pain, nausea, vomiting, or difficulty swallowing. The test can also help the doctor monitor the progress of treatment for conditions such as ulcers or tumors.
