An electrogastrogram is like a test that helps to check the movement of the muscles in your stomach. Doctors attach small sticky sensors to your tummy which measures the electrical activity. Just like how we can see the movement of our cars on a map, doctors can see the movement of our stomach on a screen. This helps the doctor to understand if there are any problems with the muscles in your stomach or if it is working properly. By understanding the results, a doctor can recommend different kinds of treatments to help you feel better.
