Why Oily Stools Prove Orlistat Is Working For You
The Science Behind Orlistat's Fat-Blocking Action
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 approximately one third of these enzymes, that proportion of fat cannot be digested or absorbed. This unabsorbed fat must exit your body naturally, resulting in the oily stools that patients experience. Rather than being a concerning side effect, oily stools are actually proof that orlistat is successfully preventing fat absorption and working as intended.
Why You See Fat in Your Stools
The oily discharge and fatty stools occur because orlistat acts locally in your gut, not systemically throughout your body. When you eat a meal containing fat, orlistat prevents approximately one third of that fat from being broken down by lipase enzymes. This undigested fat passes through your intestines unchanged and exits as oily stools, oily spotting, or urgent bowel movements. The more fat in your meal, the more pronounced these effects become - which is why following a lower-fat diet minimises these experiences while maximising weight loss benefits.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg work through identical mechanisms to block approximately one third of dietary fat absorption. The active ingredient and clinical effect are the same - the key difference is cost. At EverydayMeds, orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10). Whether you choose generic orlistat or branded Xenical, you'll experience the same fat-blocking action and the same oily stool effects that confirm the medication is working.
Managing Oily Stools While Orlistat Works
Understanding that oily stools indicate orlistat is successfully blocking fat absorption helps patients manage these effects confidently. Keep your fat intake to approximately 15g per meal to minimise oily discharge while maintaining the medication's effectiveness. Many patients find wearing dark underwear or panty liners helpful during initial treatment. These effects typically become less noticeable as you adapt to a lower-fat diet, but their presence confirms orlistat continues blocking approximately one third of dietary fat as intended.
