Singapore Gastroenterologist

A gastroscopy is a low-risk, simple and very safe procedure to perform, with most people only reporting very slight discomfort at the back of their throat for a short period of time. Complications can occur, but are very rare.

Results should be out in about 2 weeks from the date which the scope was done.

A colonoscopy, performed by a qualified and experienced gastroenterologist, is a very safe procedure that involves minimal discomfort for the patient. Although there is a risk of perforation and bleeding, it is extremely rare, occurring in 1 in every 1000 cases.

No. The colonoscopy is performed under general anaesthesia. As you will be asleep, you will not experience any pain at all. However, after the procedure, some patients may feel some bloatedness.

It depends on your risk levels for contracting colon cancer, along with any other medical conditions. However, after a polyp-free colonoscopy, most people won’t need another one for the next 5 to 10 years.
