ABSTRACT
The digestive system, which includes the esophagus, duodenum, small intestine, large intestine, and rectum, is responsible for the body's main chemical reactions, with the stomach playing a crucial role. Unfortunately, many people experience gastric dysrhythmia, which is characterized by abnormal myoelectrical rhythms in the stomach and can result in symptoms such as nausea, vomiting, early satiety, abdominal bloating, and abdominal pain. To better understand this condition, Electrogastrography (EGG) is recommended. EGG is a non-invasive method that records gastric myoelectrical contractions. Although EGG has been the dominant method used to date and has consistently demonstrated associations between arrhythmias and gastroparesis, it has limitations such as low signal quality and incomplete sensitivity and specificity. This article provides a comprehensive review of the methods used to analyze gastric abnormalities using EGG, the correlation between wearable electrogastrogram (EGG) and electromyogram (EMG), the anatomy and physiology of EGG, and its clinical significance. It also covers current practices in India and other Asian countries and the importance of EGG in long-term monitoring.
