Why Understanding Orlistat's Mechanism Matters
How Orlistat Actually Works in Your Body
Orlistat works through a specific mechanism called lipase inhibition. When you eat fat, your body uses enzymes called lipases to break it down for absorption. Orlistat blocks these enzymes, preventing approximately one third of dietary fat from being digested and absorbed. This unabsorbed fat passes through your digestive system naturally, reducing the calories your body takes in from fatty foods.
Unlike appetite suppressants that affect your brain, orlistat works locally in your gut. This targeted approach means it acts directly where fat digestion occurs, making it a reliable weight management tool when used alongside a reduced-calorie, lower-fat diet.
Why This Mechanism Proves Orlistat's Effectiveness
The lipase inhibition mechanism is precisely why orlistat works for weight management. By blocking approximately one third of fat absorption, you're reducing calorie intake from dietary fat without changing your eating behaviour dramatically. This proven mechanism has made orlistat a trusted prescription weight loss medication across the UK.
At EverydayMeds, we supply genuine orlistat 120mg from £16.89 for 42 capsules, with savings available using code EDM10. Our 4-week supply (84 capsules) costs just £29.69 after discount, providing excellent value for proven fat-blocking technology.
Stomach Pain and Orlistat - Understanding the Connection
Some patients experience stomach pain or abdominal discomfort when taking orlistat, particularly when eating high-fat meals. This occurs because unabsorbed fat creates changes in your digestive system. The mechanism that blocks fat absorption can cause gastrointestinal effects, but these typically reduce when you maintain a lower-fat diet as recommended.
Understanding that stomach discomfort relates directly to orlistat's fat-blocking action helps you manage your treatment effectively. By keeping meals to approximately 15g fat each, you minimise digestive side effects while maximising weight management benefits.
Generic Orlistat vs Xenical - Same Proven Mechanism
Both generic orlistat 120mg and branded Xenical 120mg use identical lipase inhibition mechanisms. They contain the same active ingredient at the same dose, blocking approximately one third of dietary fat absorption equally effectively. The key difference is cost - generic orlistat offers the same proven mechanism at lower prices.
Our generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while Xenical costs £42.99 for the same supply (£38.69 with EDM10). Both provide identical fat-blocking mechanisms, so choosing generic orlistat gives you proven effectiveness with better value.
Alli 60mg - Half-Strength Mechanism
Alli contains 60mg orlistat, providing the same lipase inhibition mechanism at half the prescription strength. This lower dose blocks a smaller proportion of dietary fat compared to 120mg versions, making it suitable for those preferring a gentler starting approach. Our Alli 60mg costs £28.99 for 4 weeks (£26.09 with EDM10).
