Why Understanding How Orlistat Works Matters
The Science Behind Orlistat's Fat-Blocking Action
Orlistat works through a precise mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption. When orlistat inhibits approximately one third of these enzymes, that proportion of fat passes through your body unabsorbed. This isn't guesswork - it's a scientifically proven mechanism that makes orlistat effective for weight management. Understanding this helps you make an informed choice about treatment.
Orlistat and Crohn's Disease: Individual Assessment Required
For patients with Crohn's disease, understanding orlistat's mechanism is particularly important. Since it affects fat absorption and may influence gastrointestinal symptoms, our UK-licensed prescribers carefully assess each case. The fact that orlistat works locally in the gut - not systemically throughout your body - is relevant to your individual assessment. Generic orlistat 120mg costs £32.99 for 84 capsules (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10) - same mechanism, different price.
How the Mechanism Translates to Weight Management
When you understand that orlistat blocks approximately one third of dietary fat absorption, you can see why it supports weight loss alongside a reduced-calorie, lower-fat diet. Each gram of fat contains 9 calories, so blocking fat absorption directly reduces caloric intake. This mechanism works meal by meal - take one 120mg capsule with each main meal containing fat, up to three times daily. The 168-capsule pack provides 8 weeks of treatment at £63.99 (£57.59 with code EDM10).
Comparing Your Options: Same Mechanism, Different Costs
Whether you choose generic orlistat 120mg or branded Xenical 120mg, the fat-blocking mechanism is identical. Both contain orlistat 120mg and block approximately one third of dietary fat absorption. The clinical effect is the same - the difference is price. Our 252-capsule packs offer 12 weeks of treatment: orlistat at £95.99 (£86.39 with EDM10) versus Xenical at £128.99 (£116.09 with EDM10). Understanding this helps you choose based on value while getting the same proven mechanism.
