Does Orlistat Cause Constipation? Understanding the Effects
Orlistat 120mg works by blocking approximately one third of dietary fat absorption in your digestive system. Unlike stimulant weight loss medications, orlistat acts locally in the gut and doesn't typically cause constipation. The most common side effects are actually the opposite—oily stools, increased bowel movements, and urgent need to open bowels due to unabsorbed fat passing through your system.
Our UK-licensed prescribers can assess whether orlistat is suitable for you through our online consultation process. Complete your health questionnaire today to get your prescription without visiting a GP.
Orlistat Prescription Process—Simple and Secure
Getting orlistat with prescription included couldn't be easier. Fill in our comprehensive health questionnaire covering your medical history, current medications, and weight management goals. A qualified UK prescriber reviews your information and issues a prescription where clinically appropriate. Your medication is then dispensed by our GPhC-registered pharmacy and delivered discreetly to your address.
Generic orlistat 120mg offers excellent value at £29.69 for 4 weeks (was £32.99) with code EDM10. For those preferring branded medication, Xenical 120mg is available from £38.69 for 4 weeks. Both contain identical active ingredients and work in exactly the same way.
Managing Gastrointestinal Effects While Taking Orlistat
While constipation isn't a typical orlistat side effect, some digestive changes may occur as your body adapts. Most patients experience oily spotting, fatty stools, or increased bowel movements—particularly when eating high-fat meals. These effects can be minimised by keeping fat intake to approximately 15g per meal and spreading your daily fat allowance evenly across three main meals.
Your prescriber will provide detailed guidance on managing any digestive effects. Take one 120mg capsule with each main meal containing fat, up to three times daily. If you skip a meal or eat a fat-free meal, you can omit that dose.
Choose Your Orlistat Treatment Option
We offer three orlistat options to suit different preferences and budgets. Generic orlistat 120mg provides the most cost-effective treatment, with 12 weeks available for £86.39 (was £95.99) using EDM10. Xenical 120mg offers the same clinical effect in branded form for £116.09 (12 weeks, was £128.99). Alli 60mg provides a lower-strength option at £116.99 for 12 weeks.
All treatments require completion of our online health assessment. Our prescribers will determine which strength and formulation is most appropriate for your individual circumstances, including your BMI, medical history, and weight management goals.
