How Orlistat Works for Weight Loss
Orlistat operates through targeted pancreatic lipase enzyme inhibition, reducing dietary fat absorption by approximately 25%. This mechanism:
- Blocks ~25% of consumed fat from digestion
- Promotes negative energy balance
- Encourages healthier dietary choices
Clinical studies demonstrate patients using Orlistat with lifestyle changes lose significantly more weight than diet/exercise alone (NICE, 2023).
Using Orlistat 120mg Capsules Correctly
Optimal results require strict adherence to dosing guidelines:
| Dosing Schedule | Dietary Requirements | Special Considerations |
|---|---|---|
| 1 capsule with each main meal (max 3/day) | Meals containing fat (≥15g total fat) | Skip dose if meal skipped/contains no fat |
Combine with our medically-approved Orlistat Diet Plan for enhanced results.
Orlistat Treatment Benefits and Considerations
When used appropriately under medical supervision, Orlistat offers:
- Clinically-proven weight reduction
- Improved metabolic parameters
- Reduced obesity-related health risks
Important considerations include potential gastrointestinal effects and necessary long-term lifestyle changes. Always consult your GP before starting any weight loss medication.
Potential Side Effects of Orlistat
Common gastrointestinal effects relate to undigested fat excretion:
- Oily/fatty stools (steatorrhoea) - 20-30% patients
- Increased defecation urgency - 10-15%
- Flatulence with discharge - 5-10%
These typically reduce with continued use and proper dietary management. Review the complete Orlistat Patient Information Leaflet for full safety details.
Important Safety Information
Orlistat contraindications include:
- Chronic malabsorption syndromes
- Cholestasis
- Pregnancy/breastfeeding
Drug interactions may occur with anticoagulants, antiepileptics, and thyroid medications.
