Gastroenterology

Gastroenterology is the medical specialty which deals with study of digestive system and management of its disorders. Sometimes Hepatology i.e. study of liver and bile system is also discussed under the same topic.

Diseases primarily affecting mouth and oro-pharynges are deemed more appropriate for School of Dentistry. Similarly most conditions presenting as Acute abdomen and those related to developmental anomalies will be discussed under Surgery and Pediatrics respectively.
