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 as well as disorders affecting Ano-rectal area will be described under Surgery. Diseases related to developmental anomalies will be covered in details under Pediatrics.

ICD 10 Disease classification is not strictly followed for ease of discussion.
