Gastroenterology
A gastroenterologist treats gastritis, peptic ulcer, cholecystitis, pancreatitis and other gastrointestinal diseases. A gastroenterologist can be consulted for pain in the epigastric region, the right hypochondrium, as well as for symptoms such as heartburn, nausea, bloating, belching, etc. Keep in mind that some of the gastrointestinal pathologies might be seasonal in nature, as well as have symptoms that may not bring much discomfort at the very beginning of the disease.
