Orlistat is prescribed to aid weight loss in obese people who have a body mass index (BMI) of 30kg/m² or more. It can also be prescribed to overweight people who have a BMI of 28kg/m² or more, if they have other risk factors for obesity-related diseases, such as type 2 diabetes, high blood pressure or raised cholesterol. Orlistat is not licensed for use in children under 18 years of age. However, it may sometimes be prescribed by specialists for children over 12 years of age who are obese. Orlistat is a type of medicine called a lipase inhibitor. It works by reducing the absorption of fat that you eat. Orlistat is not absorbed into the bloodstream, but works locally in the stomach and small intestine. Here it prevents the action of two enzymes called gastric and pancreatic lipases that are found in the digestive juices. Objective To examine the risk of colorectal cancer after orlistat initiation in the UK population. Setting Data from the UK Clinical Practice Research Datalink from September 1998 to December 2008. Participants 33 625 adults aged 18 years or over who started treatment with orlistat; each orlistat initiator was matched to up to five non-initiators (n=160 347) on age, sex, body mass index, and calendar time. Main outcome measures Associations between orlistat initiation and the risk of colorectal cancer, assessed by calculating hazard ratios with propensity score adjusted Cox proportional hazard models. Results Of 193 972 patients with a median age of 47 (interquartile range 37-57) years, 77% were women and approximately 90% were obese (body mass index ≥30). Orlistat initiators were more likely to have a previous history of diabetes or hypertension and to receive prescriptions for anti-diabetes drugs, statins, and aspirin compared with non-initiators. In the intention to treat analysis, 57 colorectal cancer events were identified among orlistat initiators and 246 among non-initiators, with median follow-up times of 2.96 and 2.86 years, respectively. The calculated incidence rate of colorectal cancer per 100 000 person years was 53 (95% confidence interval 41 to 69) for orlistat initiators and 50 (44 to 57) for non-initiators.

Its primary function is preventing the absorption of fats from the human diet by acting as a lipase inhibitor, thereby reducing caloric intake. It is intended for use in conjunction with a healthcare provider-supervised reduced-calorie diet. The effectiveness of orlistat in promoting weight loss is definite but modest. Pooled data from clinical trials suggest that people given orlistat in addition to lifestyle modifications, such as diet and exercise, lose about 2–3 kilograms (4.4–6.6 lb) more than those not taking the drug over the course of a year. Orlistat also modestly reduces blood pressure and appears to prevent the onset of type 2 diabetes, whether from the weight loss itself or other effects. It reduces the incidence of diabetes type II in people who are obese around the same amount that lifestyle changes do. Benefits aside, however, orlistat is notorious for its gastrointestinal side effects (sometimes referred to as treatment effects), which can include steatorrhea (oily, loose stools).
