Orlistat reduces the incidence of type 2 diabetes and improves cardiovascular risk factors (lipids, blood pressure, glycaemic control) in patients with diabetes, despite increasing gastrointestinal side effects.
If you have diabetes or high cardiovascular risk, orlistat can help lower your risk of developing more diabetes and improve your cholesterol and blood pressure. Be prepared for potential gastrointestinal side effects, which are common but often manageable.
GoodSupportsHIGH confidence
Orlistat reduced diabetes incidence, improved total cholesterol, LDL-cholesterol, blood pressure, and glycaemic control in patients with diabetes but increased rates of gastrointestinal side effects and slightly lowered HDL levels.
Why this rating
Based on subgroup analyses of RCTs included in the Cochrane review.

- Long-term pharmacotherapy with orlistat, sibutramine, or rimonabant produces modest but statistically significant weight loss (approx. 3-5 kg) compared to placebo in adults with obesity or overweight.Good
- Sibutramine improves lipid profiles (HDL, triglycerides) but increases blood pressure and heart rate, while rimonabant improves lipid profiles and glycaemic control but increases the risk of mood disorders.Good

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
