EGG full form in medical is Electrogastrogram. Electrogastrogram is a certain type of medical test which is performed to detect the electrical signals generated by the smooth muscles in the abdominal region. This test is quite common to diagnose many gastrointestinal diseases without the need for advanced imaging tests. However many doctors also prefer to refer their patients for advanced imaging tests like Ultrasound or MRI to get to know about the root cause in a better way.
EGG or Electrogastrogram was a breakthrough in the medical field since it was discovered or invented way before the invention of ultrasound and other advanced imaging methods. The main thing that an electrogastrogram does is to identify, record, and detect the myoelectrical signal in the abdominal region. These myoelectrical signals represent the contraction in the GI tract and the smooth muscles in the GI tract are responsible for generating these signals. By analyzing these signals, a medical professional can easily come to an understanding where a patient has any sort of contraction issues in the GI tract, so he/she can treat the patient accordingly.
