 Hello, I'm Dr. Govind Nandukumar. I'm a gastrointestinal surgeon. I work for Manipal Hospital's Bangalore. Gastrointestinal diseases is an area of passion and interest for me. Specifically, I take care of patients with a lot of gastrointestinal cancers. And today I'd like to tell you a little bit about what you should look for in your overall health and be concerned about as far as gastrointestinal cancers are concerned. If you have unexplained abdominal pain that stays on for a long time, if you have a change in your bowel habits or your motion or your experience bleeding when you use the bathroom, or you have excessive vomiting and indigestion, these are all reasons to see a gastrointestinal specialist. Specifically, I would advise that patients don't ignore the symptoms of bleeding and change in bowel habits. A colonoscopy, which is mandatory for patients over the age of 45 in the West, is something that we do for patients that develop bleeding in the anal area or with their bowel movements. Thank you.
