Why Understanding Orlistat's Mechanism Matters Before You Buy
How Orlistat Actually Works in Your Body
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed. When orlistat blocks approximately one third of these enzymes, roughly one third of the fat you consume cannot be digested and passes naturally through your body. This mechanism occurs locally in your gut - orlistat is not absorbed into your bloodstream in significant amounts, making it different from brain-acting appetite suppressants.
Why This Mechanism Makes Orlistat Effective
By blocking approximately one third of dietary fat absorption, orlistat can reduce the calories you absorb from meals containing fat. This creates a calorie deficit when combined with a reduced-calorie, lower-fat diet and increased physical activity. The unabsorbed fat is eliminated naturally, which is why maintaining a lower-fat diet (approximately 15g fat per meal) is essential to minimise gastrointestinal side effects.
Choose Your Orlistat Treatment Option
Generic orlistat 120mg offers the most cost-effective option at £32.99 for a 4-week supply (£29.69 with EDM10). Branded Xenical 120mg contains the identical active ingredient at £42.99 for 4 weeks (£38.69 with EDM10). For those preferring a lower-strength option, Alli 60mg is available at £28.99 for 4 weeks (£26.09 with EDM10). All three work through the same lipase inhibition mechanism.
What to Expect When Orlistat Works
The gastrointestinal effects you may experience are actually evidence that orlistat is working - they occur when unabsorbed fat passes through your system. These effects can be managed by keeping meals low in fat. Most patients find that understanding this mechanism helps them maintain the lower-fat diet essential for successful treatment. A daily multivitamin taken at bedtime is recommended as orlistat may reduce absorption of fat-soluble vitamins.
