• Proper diet and exercise are important in order to lose weight and keep it off. Follow the diet and exercise program given to you by your health care provider.
• Orlistat may cause changes in your bowel or stool (e.g., gas with oily spotting, loose stools, more frequent stools). Eating a low-fat diet may help lessen these side effects.
