Obesity is a complex disease characterized by an excess of body fat. Obesity is more than just a cosmetic issue. It is a medical condition that raises the risk of developing other diseases and health issues, such as heart disease, diabetes, high blood pressure, and certain cancers.
Some people struggle to lose weight for a variety of reasons. Obesity is typically caused by a combination of inherited, physiological, and environmental factors, as well as dietary, physical activity, and exercise choices.
The good news is that even minor weight loss can improve or prevent obesity-related health problems. Weight loss can be aided by a healthier diet, increased physical activity, and behavioral changes. Prescription medications and weight-loss procedures are also treatment options for obesity.
Obesity is frequently diagnosed using the body mass index (BMI). To calculate BMI, multiply your weight in pounds by 703, then divide it by your height in inches. Alternatively, multiply your weight in kilograms by your height in meters squared.
BMI | Weight status |
---|---|
Below 18.5 | Underweight |
18.5-24.9 | Normal |
25.0-29.9 | Overweight |
30.0 and higher | Obesity |
Asians with a BMI of 23 or higher are at a higher risk of health problems.
BMI provides a reasonable estimate of body fat for the majority of people. However, because BMI does not directly measure body fat, some people, such as muscular athletes, may have a BMI in the obesity category despite having no excess body fat.
Many doctors use waist circumference measurements to help guide treatment decisions. Weight-related health issues are more common in men with waist circumferences greater than 40 inches (102 centimeters) and in women with waist circumferences greater than 35 inches (89 centimeters).
Your doctor will usually perform a physical exam and recommend some tests to diagnose obesity.
These exams and tests typically include the following:
Gathering this information will help you and your doctor choose the type of treatment that will work best for you.
If you suffer from obesity, treatment can help you recover from conditions such as:
Obesity treatment can also lower your risk of developing certain cancers, such as breast and colon cancer. Although weight loss does not happen overnight, most people notice more energy, fewer food cravings, improved mood, and other benefits after beginning an obesity treatment program.
