Why Understanding Orlistat's Mechanism Matters
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that acts locally in your digestive system. The active ingredient inhibits lipase enzymes responsible for breaking down dietary fat in your gut. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing the calories your body takes in from dietary fat.
Why This Mechanism Makes Orlistat Effective
Unlike appetite suppressants that act on the brain, orlistat works directly where fat digestion occurs. This targeted approach means the medication can support weight management without affecting your central nervous system. The mechanism is dose-dependent - orlistat 120mg and Xenical 120mg provide maximum lipase inhibition, while Alli 60mg offers a lower-strength option. Understanding this helps you choose the right treatment strength following clinical assessment.
Monthly Costs for Each Orlistat Option
Generic orlistat 120mg offers the most cost-effective option at £32.99 monthly (£29.69 with EDM10 code). Xenical 120mg, containing the identical active ingredient from Roche, costs £42.99 monthly (£38.69 with EDM10). Alli 60mg, the lower-strength version, costs £28.99 monthly (£26.09 with EDM10) for a 4-week supply. All prices include prescription costs, with 10% savings available on every order using code EDM10.
What to Expect When Orlistat Works
The mechanism of blocking approximately one third of dietary fat means you may experience gastrointestinal effects, particularly when eating high-fat meals. These effects - including oily stools or increased bowel frequency - are actually signs the medication is working as intended. Keeping meals low in fat (approximately 15g per meal) significantly reduces these effects while maintaining orlistat's weight management benefits.
Proven Results Through Fat Blocking
Clinical studies demonstrate that orlistat's fat-blocking mechanism can support significant weight loss when used alongside a reduced-calorie, lower-fat diet. The medication works best as part of a structured weight management programme including dietary changes and increased physical activity. Individual responses vary, but the consistent mechanism means orlistat may help reduce calorie intake from dietary fat in suitable patients.
