Xenical is a medicine used to help obese patients lose weight. It contains 120mg of the active ingredient orlistat and may be prescribed to patients with a BMI above 30.

Xenical works by binding to enzymes in the digestive system called lipases. Lipases break down fats from your food so that it can be absorbed in the intestines. When this effect is hindered, the fat from your food will pass through the intestines instead of being absorbed.

Xenical capsules are indicated for use in patients with a BMI above 30. They may also be prescribed to patients with a BMI above 28 if there are associated risk factors present, such as type 2 diabetes.

What Does BMI Mean And How Do I Measure My BMI?

BMI is short for Body Mass Index. It is a chart used to help yourself and health professionals understand your healthy weight range based on your height. WHO, the World Health Organisation, considers a BMI of between 18.5 and 25 represent a healthy weight. A BMI of 30 or above is considered obese.
