Xenical (Orlistat) is used to help with weight loss in obese people who wish to reduce their weight, so as to reduce the risk of high blood pressure, diabetes, breathing difficulties and other
complications that can occur as a result of obesity. Patients whose diet contains too much fat may gain weight due to the body storing any excess fat. However, this medicine acts in the digestive
system and attaches itself enzymes (called lipases), and prevents the body from absorbing the fat. Instead, the fat is removed in the patient`s feces, leading to a reduction of one third in the
amount of fat that the body absorbs.
