Why Orlistat's Mechanism Makes It Worth Buying

How Orlistat Blocks Fat Absorption

Orlistat works through a scientifically proven mechanism that directly targets dietary fat. The medicine inhibits lipase enzymes in your digestive system, preventing approximately one third of the fat you eat from being broken down and absorbed. This unabsorbed fat passes naturally through your body, reducing calorie intake from dietary sources. Unlike appetite suppressants that act on the brain, orlistat works locally in the gut and is not significantly absorbed into your bloodstream.

Why This Mechanism Proves Effectiveness

The lipase inhibition mechanism demonstrates why orlistat delivers measurable results. When you take orlistat 120mg three times daily with meals containing fat, you consistently block approximately one third of dietary fat absorption. This translates to fewer calories absorbed from fat sources, supporting weight management when combined with a reduced-calorie, lower-fat diet. Generic orlistat 120mg costs just £29.69 for 4 weeks with code EDM10, making this proven mechanism accessible.

Orlistat vs Xenical - Same Fat-Blocking Power

Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose, delivering the same fat-blocking mechanism. Orlistat 4-week supply costs £29.69 with EDM10, while Xenical costs £38.69 - a £9 monthly saving for identical clinical effect. Some patients prefer branded Xenical, while others choose generic orlistat for value. Both require prescription following online clinical assessment.

Managing Side Effects Through Understanding

Knowing how orlistat works helps you minimise side effects effectively. Gastrointestinal effects like oily stools or urgency occur because unabsorbed fat must exit your body. These effects reduce significantly when you limit meals to approximately 15g fat each. The side effects actually confirm the mechanism is working - they're your body's response to blocked fat absorption.
