Why Orlistat's Mechanism Makes It Effective Post-Gallbladder
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting pancreatic lipase enzymes in your small intestine, blocking approximately one third of the fat you eat from being absorbed. This mechanism is completely independent of gallbladder function - orlistat acts directly on the enzymes that break down dietary fat, preventing absorption regardless of bile storage capacity. The unabsorbed fat passes naturally through your digestive system.
Post-Gallbladder Surgery: Why Orlistat Still Works
Following gallbladder removal (cholecystectomy), your liver continues producing bile which flows directly into your small intestine. Orlistat's fat-blocking mechanism occurs after bile has mixed with food, targeting the lipase enzymes specifically. Clinical studies show orlistat remains effective in patients without gallbladders, making it a suitable weight management option when used alongside a reduced-calorie, lower-fat diet.
Choosing Between Orlistat and Xenical
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. Orlistat 4-week supply costs £32.99 (£29.69 with EDM10), whilst Xenical costs £42.99 (£38.69 with EDM10). The clinical effect is identical - generic orlistat simply offers better value whilst delivering the same proven fat-blocking action.
Dosing for Maximum Fat-Blocking Effect
Take one 120mg capsule three times daily with each main meal containing fat. This dosing schedule ensures optimal lipase enzyme inhibition throughout your day. If you skip a meal or eat a fat-free meal, you can omit that dose. Following gallbladder surgery, maintaining this regular dosing pattern helps maximise orlistat's fat-blocking mechanism whilst minimising gastrointestinal side effects.
