I had a colonoscopy a week ago today and still feeling bloated?

Prabanely normal: As long you do not have blood in the stools, distended and painful abdomen, and no vomiting you should be alright if it persist than call the gastroenterologist.

Need to be checked: Bloating following a colonoscopy should be gone within a few hours to a day unless there was significant difficulty with the procedure or pathological findings that flared with the procedure. If your symptom does not start resolving by tomorrow, you should contact your endoscopist to make sure you do not have a complication such as a small perforation(probably "walled off" or you would be sicker).
