At the BNH Hospital, Bangkok, there is advanced gastroenterology infrastructure to provide UGI Endoscopy for diagnosing and evaluating all conditions affecting the upper digestive tract. The JCI accredited hospital was established in 1898 and is located in Bangkok, Thailand, with 150 beds.

In the procedure of UGI Endoscopy, a thin, flexible tube with a tiny camera is passed through the mouth to examine esophagus, stomach and duodenum. Detection of abdominal pain, reflux, swallowing problems, ulcers and bleeding in the gastrointestinal tract becomes possible with its help. When the need arises, the doctors can take tissue samples for laboratory testing.
