Electrogastrogram

Electrogastrogram (EGG) is a non-invasive procedure used to measure the electrical activity of the stomach. The procedure is similar to an ECG, which measures the electrical activity of the heart. The EGG is used to diagnose several different conditions, including gastroparesis, GERD, and functional dyspepsia.

Procedure[edit | edit source]

The EGG procedure involves placing electrodes on the skin over the stomach. These electrodes detect the electrical signals that control the muscles of the stomach. These signals are then amplified and recorded for analysis. The patient may be asked to fast before the procedure, and to avoid certain medications that can affect the results.

Uses[edit | edit source]

The EGG is used to diagnose several different conditions. These include:

Gastroparesis, a condition in which the muscles of the stomach do not function properly, causing food to be digested slowly or not at all.
GERD, a condition in which stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus).
Functional dyspepsia, a chronic disorder of sensation and movement (peristalsis) in the upper digestive tract.

Risks[edit | edit source]

The EGG is a safe procedure with few risks. However, some people may experience minor discomfort from the electrodes. There is also a small risk of skin irritation from the adhesive used to attach the electrodes.

Interpretation[edit | edit source]

The results of the EGG are interpreted by a gastroenterologist, who will look for abnormal patterns of electrical activity. These patterns can indicate a problem with the muscles of the stomach, or with the nerves that control these muscles.
