Drug treatment

​

Anti-obesity medications work by

• Reducing appetite, by replicating the hormone that makes you feel full after a meal, or

​

• Reducing fat absorption from the gastrointestinal tract. 

​

Drug treatments can help reduce obesity-related health risks such as high blood pressure and diabetes.

They should not be used, however, as a substitute for lifestyle changes such as eating a more healthy diet or increasing the amount of physical exercise.

​

​

Drug treatments can be considered if your BMI is:

≥30 kg/m2 or

 ≥25 kg/m2 (with obesity-related complications, including breathing problems during sleep (OSA).
