Why Orlistat's Fat-Blocking Action Causes Diarrhea
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by inhibiting lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed into your bloodstream. This unabsorbed fat must exit your body naturally, which explains the gastrointestinal effects including loose stools and oily discharge. Rather than being a side effect to worry about, these symptoms actually prove orlistat is working effectively to block fat absorption.
Why Fat Blocking Leads to Digestive Changes
When orlistat blocks approximately one third of the fat you eat, this undigested fat passes through your intestines unchanged. Your body cannot store what it cannot absorb, so the blocked fat is eliminated through bowel movements. This is why many patients experience oily stools, increased frequency, or urgent bowel movements - it's the blocked fat leaving your system. The more fat in your meal, the more pronounced these effects become.
Generic Orlistat vs Xenical - Same Fat-Blocking Power
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and block approximately one third of dietary fat equally effectively. Generic orlistat costs £29.69 for a 4-week supply (with EDM10), while Xenical costs £38.69 - a saving of £9 monthly. Longer supplies offer better value: 12-week generic orlistat costs £86.39 compared to Xenical at £116.09. Both work through the same proven fat-blocking mechanism.
Managing Digestive Effects While Maintaining Fat Blocking
The key to successful orlistat treatment is keeping each meal below 15g fat content. This maximises the fat-blocking benefits while minimising digestive disruption. When you eat high-fat meals, orlistat still blocks approximately one third of fat, but the larger amount of unabsorbed fat causes more noticeable bowel changes. Planning lower-fat meals helps you maintain the weight loss benefits while reducing toilet urgency and oily discharge.
