Why Orlistat's Mechanism Causes Stomach Effects
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When orlistat blocks these lipases, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes through your gut and is eliminated naturally from your body.
This mechanism explains why orlistat can cause stomach pain and other gastrointestinal effects. The undigested fat moving through your digestive system can cause abdominal discomfort, bloating, and changes to your bowel movements. Understanding this helps you manage the effects better.
Managing Stomach Pain While Taking Orlistat
Stomach pain from orlistat is directly related to how much fat you eat. High-fat meals significantly increase gastrointestinal side effects because there's more unabsorbed fat passing through your system. Keep meals to approximately 15g of fat each to minimise discomfort.
At EverydayMeds, we supply all three orlistat options. Generic orlistat 120mg offers excellent value at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg costs £42.99 for 4 weeks (£38.69 with EDM10). Lower-strength Alli 60mg is £28.99 for 4 weeks (£26.09 with EDM10).
Why the Mechanism Proves Orlistat Works
The fact that orlistat can cause stomach effects actually demonstrates it's working effectively. When you experience gastrointestinal symptoms, it shows the medication is successfully blocking fat absorption in your digestive system. This unabsorbed fat represents calories that won't contribute to weight gain.
However, not everyone experiences significant stomach pain. Following a reduced-calorie, lower-fat diet as recommended significantly reduces these effects while maximising weight management benefits. Our UK-licensed prescribers provide guidance on managing your treatment effectively.
Choosing Your Orlistat Treatment
All orlistat products work through the same fat-blocking mechanism. Generic orlistat 120mg and Xenical 120mg contain identical active ingredients at the same dose - the key difference is cost. Generic orlistat saves approximately £9 per month compared to Xenical.
For longer treatment courses, our 12-week supplies offer better value. Orlistat 120mg costs £95.99 for 252 capsules (£86.39 with EDM10), while Xenical costs £128.99 (£116.09 with EDM10). Alli 60mg 12-week supply costs £129.99 (£116.99 with EDM10).
