Understanding Orlistat Side Effects Before You Buy

Can Orlistat Cause Stomach Pain and Digestive Issues?

Yes, orlistat can cause stomach pain and various gastrointestinal side effects. Abdominal pain or discomfort affects more than 1 in 10 people taking orlistat, making it a very common side effect. These effects occur because orlistat works by blocking approximately one third of dietary fat absorption, causing unabsorbed fat to pass through your digestive system.

At EverydayMeds, we help you understand these effects before starting treatment. Our generic orlistat 120mg costs just £29.69 for a 4-week supply with code EDM10, while Xenical 120mg costs £38.69. Both contain identical active ingredients and may cause similar side effects.

Common Gastrointestinal Side Effects of Orlistat

Beyond stomach pain, orlistat commonly causes oily or fatty stools, urgent bowel movements, increased frequency of stools, oily spotting, and flatulence with discharge. These effects are directly linked to your fat intake - higher fat meals significantly increase side effect likelihood and severity.

Our lower-strength Alli 60mg option (£26.09 for 4 weeks with EDM10) typically causes milder side effects than prescription-strength orlistat. All three products work through the same mechanism but at different potencies.

Managing Side Effects While Taking Orlistat

You can minimise stomach pain and other side effects by keeping dietary fat low - approximately 15g per meal or 30% of daily calories from fat. Spreading fat intake evenly across three main meals helps prevent concentrated fat loads that trigger severe symptoms.

Most patients find side effects reduce over time as they adapt their diet. However, if you experience severe abdominal pain, dark urine, or yellowing of skin/eyes, seek immediate medical attention as these may indicate serious complications.
