How do obesity medications work?

Obesity medications work by targeting the brain and/or digestive system to suppress appetite, increase feelings of fullness, and reduce the absorption of calories from food. Some medications, such as phentermine, stimulate the release of norepinephrine, a neurotransmitter that can reduce appetite. Others, such as liraglutide, mimic the effects of a hormone called GLP-1 to reduce appetite and improve blood sugar control. Still, others, such as orlistat, block the absorption of fat in the digestive tract, thereby reducing calorie intake. Combined with lifestyle changes, obesity medications can be an effective tool for weight loss in those who are severely obese.
