Understanding Orlistat Side Effects and Getting Treatment
Why Does Xenical Make You Poop Differently?
Xenical (orlistat 120mg) works by blocking lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed. This unabsorbed fat must leave your body naturally through bowel movements, which explains why many people experience gastrointestinal side effects including oily stools, increased frequency, or urgent bowel movements. These effects are actually a sign the medication is working as intended.
Managing Bowel Changes While Taking Orlistat
The key to minimising digestive side effects is following a lower-fat diet with no more than 15g of fat per meal. When you eat high-fat meals while taking orlistat, you're more likely to experience oily spotting, urgent bowel movements, or fatty stools. Most patients find these effects reduce significantly once they adapt their diet and establish a routine with the medication.

What to Expect During Treatment
Most patients experience some gastrointestinal effects during their first few weeks of treatment, including changes to stool consistency, frequency, or urgency. These side effects typically improve as your body adjusts and you follow a lower-fat diet consistently. Your prescriber will provide comprehensive guidance on managing these effects while maximising the benefits of treatment.
