Obesity is a complex disease involving an excessive amount of body fat. Obesity isn’t just a cosmetic concern. It is a medical problem that increases your risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure, and certain cancers.

There are many reasons why some people have difficulty avoiding obesity. Usually, obesity results from a combination of inherited factors, combined with the environment and personal diet and exercise choices. The good news is that even modest weight loss can improve or prevent the health problems associated with obesity. Dietary changes, increased physical activity, and behavior changes can help you lose weight. Prescription medications and weight-loss procedures are additional options for treating obesity.


Eating more calories than you burn in daily activity and exercise — on a long-term basis — can lead to obesity. Over time, these extra calories add up and cause weight gain. But it’s not always just about calories in and calories out, or having a sedentary lifestyle. While those are indeed causes of obesity, some causes you can’t control. Common specific causes of obesity include genetics, aging, not sleeping enough, and pregnancy. Certain health conditions can also lead to weight gain, which may lead to obesity. These include polycystic ovary syndrome, Prader-Willi syndrome, Cushing syndrome, hypothyroidism, and osteoarthritis (OA).


The goal of obesity treatment is to reach and stay at a healthy weight. This improves your overall health and lowers your risk of developing complications related to obesity. You may need to work with a team of health professionals — including a dietitian, behavioral counselor, or an obesity specialist — to help you understand and make changes in your eating and activity habits. All weight-loss programs require changes in your eating habits and increased physical activity. The treatment methods that are right for you depend on your obesity severity, your overall health, and your willingness to participate in your weight-loss plan.
