Orlistat is a medication that can help with weight loss by reducing the amount of fat absorbed from food. It's available over-the-counter and by prescription.

Orlistat prevents the enzyme lipase from breaking down fat in the intestines. This means that some of the fat you eat passes through your system undigested and is eliminated in your stool. This can help you lose weight by reducing your caloric intake.

Orlistat is used to treat obesity and overweight people. It can also be used after weight loss to prevent regaining weight.

Orlistat is a prescription-only weight loss medication that contains the active ingredient of the same name. It works by blocking the enzymes responsible for absorbing the fat you eat and instead removes it from your body as stool waste. Orlistat is available in the form of an oral pill. When taken alongside a healthy calorie-controlled diet, it is an effective weight loss medication. Research has found that orlistat can help 37% of people lose 5% of their body weight after 12 weeks of treatment.
