Introduction
This information will help you understand your choices, whether you share in the decision-making process or rely on your doctor's recommendation.
Key points
Many people seek medical help in dealing with obesity. While medicines often promote weight loss, they may have side effects, and the weight loss may be temporary. Consider the following when making your decision:
- If you are losing weight, even as little as
per week, you may not get enough additional benefit from medicine to outweigh the cost and side effects. - You will likely gain weight back after you stop using medicine.
- Weight-loss medicines generally are used only if you have tried a weight management program, including diet and exercise, for at least 6 months, and your body mass index (BMI) is 30 or more. If you are Asian, your health may be at risk with a BMI of 27.5 or more.1 Talk to your doctor if your BMI is 27 to 30 and you have a condition that is made worse by being overweight. These conditions include high blood pressure, type 2 diabetes, high cholesterol, coronary artery disease, joint problems, and sleep apnea.
- If you are under severe stress, have an emotional illness such as anxiety or depression, or have an alcohol or drug problem, you need treatment for this condition before using medicine. If you don't treat it, it will make losing weight more difficult.
- It is not known whether it is safe for you to take medicines for obesity for longer than 2 years.
This Decision Point concerns obesity in adults. If you have a child that you think needs medicine to lose weight, consult your health professional.
