Obesity Patient Education
Obesity means a person has too much body fat. It is sometimes described as when a person has a body weight that is greater than what is healthy for their height, but that does not take into account the added weight of muscle mass. Obesity is a condition of excess weight due to too much body fat, not too much muscle.
Obesity is not a disease itself. It is a condition that can increase a person’s risk for certain health problems such as heart attack, stroke, type 2 diabetes, breathing problems, and some types of cancer.
According to statistics from the US Centers for Disease Control and Prevention, 36 percent of adults and 17 percent of children and teens in America are obese.
Doctors Who Treat Obesity

Internist or Family Physician - Doctors who provide general medical care for adults. An internist or family physician typically diagnoses adults who are obese and can manage their weight loss program.
Pediatrician - Doctor who specializes in the medical care of children. A pediatrician typically diagnoses children who are obese and can manage their weight loss program.

Exercise physiologists and certified trainers can help obese people lose weight by teaching them exercise programs that are appropriate for their fitness level.
How to Prepare for Your Obesity Doctor Visit

Common Tests or Labs to Diagnose Obesity
Obesity is diagnosed based on a physical examination. In many cases, a doctor can determine if you are obese by looking at your body. They can also take body measurements to calculate your body mass index (BMI) and waist circumference. These tests are described in the table below.
|Test||Why Test?||What Happens?||Results|
|Body mass index (BMI)||To determine if a person’s weight is too much for their height||Height and weight are measured. BMI is calculated by dividing weight in kilograms by height in meters squared (kg/m2).||BMI 18.5 – 24.9 = normal
BMI 25 – 29.9 = overweight
BMI 30 or higher = obese
|Waist circumference||To determine if a person has excess fat around the waist||A tape measure is used to measure around the waist.||The following waist measurements indicate increased health risks related to excess body fat around the waist.
Women: more than 35 inches
Men: more than 40 inches
BMI indicates whether your weight is too much for your height. Measuring waist circumference helps determine whether you are at increased risk for certain health problems related to obesity. Excess fat around the waist increases your risk of developing type 2 diabetes and heart disease.
In most cases, a high BMI indicates that a person has excess body fat. However, some people have a high BMI because they have excess muscle. These people tend to be high-performing athletes or people who lift weights extensively (such as body builders). When a person’s BMI is high but he or she does not appear to have excess body fat, skin fold measurements and other tests can be performed to calculate body fat percentage. This is a way to distinguish between excess body fat and excess muscle tissue. These tests are not commonly performed, however, because excess body fat is usually evident during a physical exam.
Common Medications and Treatments for Obesity
The main treatment for obesity is weight loss achieved through changes in diet and increasing physical activity. While the optimal diet and the amount and type of exercise for each person will vary, weight loss programs are focused on eating fewer calories and burning more calories through exercise. Your doctor can recommend the type of diet and exercise program that is right for you and refer you to a registered dietitian and exercise trainer to help guide you.
Weight-loss medications are also available. These work best when combined with healthy eating habits and increased physical activity. The table below describes the common prescription weight-loss medications used to treat obesity.
|Drug Category||How it works|
Weight loss surgery (also called bariatric surgery) may be an option for people with severe obesity (BMI more than 40) or a BMI more than 35 with a serious health problem related to obesity. The table below describes the four common weight loss surgeries in the United States.
|Type of surgery||How it works|
