Understanding Orlistat Side Effects Before You Buy
Can Orlistat Cause Nausea? What You Need to Know
Yes, orlistat can cause nausea as a common side effect, affecting up to 1 in 10 people taking this prescription weight loss medication. At EverydayMeds, our UK-licensed prescribers ensure you understand all potential side effects before starting treatment. Nausea typically occurs alongside other gastrointestinal effects and often reduces as your body adapts to the medication and a lower-fat diet.
The good news is that nausea with orlistat is usually manageable and temporary. Most patients find that keeping dietary fat intake low (approximately 15g per meal) significantly reduces both nausea and other side effects. Our clinical team provides comprehensive guidance on minimising side effects while maximising treatment benefits.

Managing Nausea and Other Side Effects
Beyond nausea, orlistat may cause other gastrointestinal side effects including oily stools, increased bowel movements, and abdominal discomfort. These effects are directly linked to the medication's mechanism - blocking approximately one third of dietary fat absorption. The unabsorbed fat passes naturally through your digestive system.
To minimise nausea and optimise your treatment:
• Keep fat intake to approximately 15g per meal
• Spread daily fat intake evenly across three main meals
• Take orlistat with each main meal containing fat
• Consider a daily multivitamin (taken at bedtime, 2+ hours after your last dose)
Remember that side effects often indicate the medication is working effectively. However, if nausea becomes severe or persistent, contact your prescriber for personalised advice.
