Orlistat improves cardiovascular risk factors, including reducing the incidence of type 2 diabetes and improving lipid profiles, despite causing gastrointestinal side effects.
Orlistat not only aids weight loss but also significantly reduces the risk of developing type 2 diabetes in obese individuals with impaired glucose tolerance. It also improves cholesterol and blood pressure. However, users must manage gastrointestinal side effects, which are common but not necessarily dangerous.
GoodSupportsHIGH confidence
Orlistat reduced the incidence of diabetes and improved concentrations of total cholesterol and low density lipoprotein cholesterol, blood pressure, and glycaemic control in patients with diabetes but increased rates of gastrointestinal side effects and slightly lowered concentrations of high density lipoprotein.
Why this rating
Based on subgroup analyses within the meta-analysis, including a large 4-year trial (XENDOS).

More from this paper
- Long-term pharmacotherapy with orlistat, sibutramine, or rimonabant produces modest but statistically significant weight loss (2.9–4.7 kg) compared to placebo in adults with obesity, while improving specific cardiovascular risk factors.Good
- Sibutramine and rimonabant produce greater weight loss than orlistat but carry distinct adverse effect profiles: sibutramine increases blood pressure and heart rate, while rimonabant increases the risk of mood disorders.Good
