How Orlistat's Fat-Blocking Action Drives Results
Why Orlistat Causes Diarrhea - The Science Behind It
Orlistat causes diarrhea because of exactly how it works to support weight loss. The medication inhibits lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being broken down and absorbed. This unabsorbed fat cannot simply disappear - it passes through your body and exits naturally, often causing loose, oily stools and the urgent need for bowel movements that patients experience.
This mechanism proves orlistat is actively working. The gastrointestinal effects you may experience are direct evidence that fat is being blocked from absorption. At EverydayMeds, our orlistat 120mg costs just £29.69 for a 4-week supply with code EDM10, making this proven treatment highly accessible.
The Fat-Blocking Mechanism That Delivers Weight Loss
Understanding orlistat's mechanism helps explain why it's effective for weight management. When you eat a meal containing fat, orlistat blocks approximately one third of that fat from being digested. Since fat contains 9 calories per gram - more than twice that of carbohydrates or protein - this blocked fat represents significant calorie reduction.
Generic orlistat 120mg and branded Xenical 120mg work identically, both containing the same active ingredient at the same dose. The key difference is cost - our generic orlistat saves approximately £9 per month compared to Xenical. Both require prescription following clinical assessment by a UK-licensed prescriber.
Managing Side Effects While Maximising Results
The oily stools and diarrhea associated with orlistat can be minimised by keeping dietary fat intake low - approximately 15g fat per meal. This approach reduces side effects significantly while allowing the medication to work effectively on the fat you do consume.
Alli 60mg offers a lower-strength option at half the prescription dose, potentially causing milder gastrointestinal effects. However, it also blocks a smaller proportion of dietary fat. Our Alli 60mg costs £26.09 for a 4-week supply with EDM10, providing flexibility for different patient preferences.
