Xenical

Xenical (sometimes known as Orlistat) is an oral drug prescribed to help obese people lose weight. It is generally prescribed only where there is a body mass index (BMI) of 30kg/m² or more, and where other methods of weight loss have proved ineffective.

It’s unlike other diet pills, which tend to work by suppressing the appetite. Xenical works by stopping absorption of fat in your digestive system. Fat molecules are large – too large to be absorbed into the bloodstream straight from the gut. Instead, they are broken down during the digestion process. They are broken down by enzymes, known as “gastric and pancreatic lipases”. 

Xenical works by stopping these enzymes from functioning. Instead, fat eaten in meals is not broken down, so not absorbed by the body at all. The body is then unable to use the fat, either as energy, or to convert it into fat tissue. Instead, the fat simply passes through as a waste product. This aids weight loss. 

Xenical is the only ‘fat blocker’ diet pill that is available on prescription. For the pill to have effect, it should not be used alone, but taken in conjunction with changes in lifestyle, such as healthy eating, reduced calorie intake, and more exercise. This is vital due to the nature of the medication. As fats are not absorbed, and go straight through, continuing to eat a diet high in fat alongside Xenical can lead to unpleasant side effects, such as diarrhoea or incontinence. As with any diet pill, it should be used for a limited time only.  The recommended period is three months.

Xenical is a prescription only drug but once you have the prescription, you can buy Xenical online from authentic online chemists like UK Medix.
