Xenical is used with reduced calorie diet and intended to treat obesity in people having BMI above 26. BMI is your Body Mass Index, a statistical measure which compares a person's weight and height to estimate body weight.


How Xenical Works?



Xenical’s primary function is preventing the absorption of fats in your body taken from your meal. If you eat an excessive amount of fat or calories in your meal, the excess is stored as fat by the body, which results in weight gain. When you eat fat, your body breaks it down into its simplest components so that it can be digested. Xenical works in your digestive system and blocks about one-third of the fat being digested, you have eaten in your meal. Xenical is not absorbed into the bloodstream although it works in the stomach and small intestine. The undigested fat cannot be absorbed and is eliminated in your bowel movements.



There are Enzymes in your digestive system, which are called lipases and help digest or break down fat. When taken with meals, Xenical attaches itself to the lipases and blocks them from breaking down some of the fat you have eaten. Xenical’s active ingredient Orlistat inhibits the action of the naturally occurring lipases and blocks absorption of dietary fat.

Like other diet and weight loss pills, Xenical is designed for obese people who are under medical supervision. In such cases, Xenical may be an effective short-term treatment. However dieter has to change eating habits or adopt exercise habits - two things that are essential for long-term weight management. No diet or weight loss pill can help your getting good results without diet and exercise.



Following one year of treatment in adult obese patients, Xenical in combination with diet was shown to be more effective in weight loss than diet alone. In most cases, weight loss was gradual. Patients treated with Xenical and a reduced-calorie diet for one year lost an average of 13.4 pounds while those on a reduced-calorie diet alone lost 5.8 pounds.



Following one year of treatment in adolescent obese patients, Xenical in combination with diet was shown to be more effective in reducing Body Mass Index (BMI) than diet alone. A reduction in Body Mass Index is a better indicator of weight loss in children because it takes into account changes in weight related to growing children.



Xenical is not for everyone. Since it's made for prescription, it's given to those who are seriously obese and in need of prescription weight loss treatment.
