Understanding how orlistat works helps explain why it's effective for weight management. Orlistat blocks approximately one third of dietary fat absorption by inhibiting lipase enzymes in your gut. This proven mechanism means unabsorbed fat passes naturally through your body, supporting weight loss alongside a reduced-calorie diet. When trying to conceive, achieving a healthy weight is important. Generic orlistat starts from £29.69 for 4 weeks with code EDM10. Our UK-licensed prescribers assess suitability following online consultation. Get prescription orlistat delivered discreetly across the UK.

Proven Fat-Blocking Mechanism - Ready to Start Today

How Orlistat's Fat-Blocking Action Works

Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption. When orlistat inhibits these lipases, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is excreted.

This local action in the gut means orlistat isn't significantly absorbed into your bloodstream, making it different from appetite suppressants that act on the brain. The mechanism is immediate - orlistat starts blocking fat absorption from your very first dose when taken with meals containing fat.

Why This Mechanism Supports Weight Management

By blocking approximately one third of dietary fat absorption, orlistat reduces the calories your body absorbs from fatty foods. Since fat contains 9 calories per gram (compared to 4 calories per gram from carbohydrates or protein), blocking fat absorption can significantly reduce your total calorie intake when combined with a lower-fat diet.

Generic orlistat 120mg costs just £29.69 for a 4-week supply (84 capsules) with code EDM10, while branded Xenical containing the same active ingredient costs £38.69 for 4 weeks. Both work through identical fat-blocking mechanisms.

Orlistat When Trying to Conceive - Weight Management Benefits

When trying to conceive, achieving a healthy BMI can support fertility. Orlistat may help some women reach a healthier weight through its proven fat-blocking action. However, orlistat should not be used during pregnancy or while actively trying to conceive, as weight loss during pregnancy isn't recommended.

If you're planning to conceive, speak with your healthcare provider about timing your weight management programme. Many women use orlistat to achieve their target weight before trying to conceive, then stop treatment when actively trying for pregnancy.

Three Options - Same Fat-Blocking Mechanism

We offer three orlistat options, all working through the same lipase-inhibiting mechanism:

Generic Orlistat 120mg: Most cost-effective option. 12-week supply (252 capsules) costs £86.39 with EDM10 - saving over £40 compared to branded Xenical.

Xenical 120mg: Branded version by Roche. Contains identical active ingredient. 12-week supply costs £116.09 with EDM10.

Alli 60mg: Lower-strength option blocking a smaller proportion of dietary fat. 12-week supply costs £116.99 with EDM10.
