Orlistat is a prescription medication that helps you lose weight by preventing your body from absorbing about a third of the fat you consume. It works by blocking the action of lipases, enzymes that break down fats in your digestive system. This means fewer fat calories are absorbed into your bloodstream, contributing to weight loss.
How Orlistat Works in the Body
After you eat a meal containing fats, Orlistat acts in your intestines. It binds to lipases, making them unable to digest fats. These undigested fats are then passed out of your body in your stool. This process can lead to changes in bowel habits, including oily stools, gas, and frequent bowel movements. These side effects are common and usually temporary, lessening as your body adjusts.
Who Should Consider Orlistat?
Orlistat is typically prescribed to individuals with a Body Mass Index (BMI) of 30 or higher (obese) or a BMI of 27 or higher (overweight) who also have weight-related health problems like high blood pressure or type 2 diabetes. It’s most effective when combined with a reduced-calorie diet and increased physical activity. Your doctor will determine if Orlistat is right for you based on your individual health circumstances.
Important Note: Orlistat is not a magic bullet. It requires a commitment to lifestyle changes for optimal results. Consult your doctor before starting any weight-loss program, including using Orlistat.
Potential Side Effects to be Aware Of
Gastrointestinal side effects are the most common, including oily stools, gas, and urgent bowel movements. Less frequent side effects can include stomach pain, headache, and upper respiratory tract infections. Discuss any concerns you have with your physician.
