How Does Orlistat Work vs Traditional Appetite Suppressants?
Understanding How Orlistat Works
Unlike traditional appetite suppressants that work on the brain, orlistat works locally in your digestive system. It inhibits lipase enzymes that break down dietary fat, preventing approximately one third of fat from being absorbed. This unabsorbed fat passes naturally through your body. Orlistat doesn't affect hunger signals or brain chemistry - it's a fat absorption blocker, not an appetite suppressant.
Private Prescription Benefits vs NHS Route
The NHS provides orlistat but with eligibility criteria and potential waiting times for GP appointments. Our private prescription service offers faster access through online clinical assessment. UK-licensed prescribers review your health questionnaire and can issue prescriptions where clinically appropriate, without face-to-face GP visits.

Clinical Assessment Process
Complete our online health questionnaire covering medical history, current medications, and BMI information. UK-licensed prescribers review your submission and issue prescriptions where appropriate. Our GPhC-registered Leicester pharmacy dispenses and dispatches with next-day tracked delivery. The entire process typically takes 24-48 hours from assessment to delivery.
Managing Treatment Expectations
Orlistat works best alongside a reduced-calorie, lower-fat diet with no more than 15g fat per meal. Higher fat intake increases gastrointestinal side effects like oily stools and urgent bowel movements. These effects indicate the medication is working - blocking fat absorption. Most side effects reduce as you adapt to lower-fat eating patterns.
Who May Be Suitable
Adults with BMI 30kg/m² or above, or BMI 28kg/m² with weight-related health conditions like type 2 diabetes or high blood pressure may be suitable. Final eligibility depends on individual clinical assessment. Not suitable during pregnancy, breastfeeding, under-18s, or those with certain medical conditions. Your prescriber will determine appropriate treatment based on your health circumstances.
