Why Does Orlistat Cause Stomach Pain?
Orlistat works by blocking approximately one third of dietary fat absorption in your digestive system. When unabsorbed fat passes through your gut, it can cause abdominal pain, cramping, and discomfort. This is particularly common when eating meals containing more than 15g of fat. The pain occurs because your digestive system is processing and eliminating the blocked fat, which is actually a sign the medication is working as intended.
How Common Is Stomach Pain with Orlistat?
Abdominal pain is classified as a very common side effect, potentially affecting more than 1 in 10 people taking orlistat. At EverydayMeds, our UK-licensed prescribers explain that stomach discomfort typically reduces over the first few weeks as your diet adapts. Generic orlistat 120mg (£32.99 for 84 capsules, £29.69 with EDM10) and branded Xenical (£42.99 for 84 capsules, £38.69 with EDM10) both carry the same side effect profile, as they contain identical active ingredients.
Managing Stomach Pain While Taking Orlistat
The most effective way to minimise stomach pain is keeping each meal to approximately 15g of fat or less. This significantly reduces gastrointestinal side effects while maintaining orlistat's fat-blocking benefits. Our regulated online consultation includes dietary guidance to help manage symptoms effectively. If you're considering Alli 60mg (£54.99 for 84 capsules, £49.49 with EDM10), this lower dose may cause milder stomach discomfort for some patients.
When to Seek Medical Advice
While mild stomach pain is expected, severe abdominal pain requires immediate medical attention. Contact a healthcare professional if you experience persistent, severe cramping, signs of dehydration, or pain that interferes with daily activities. EverydayMeds' UK-licensed prescribers are available for ongoing support throughout your treatment.
