The Health Effects of Overweight and Obesity



The Health Effects of Overweight and Obesity



Research has shown that as weight increases to reach the levels referred to as "overweight" and "obesity,"* the risks for the following conditions also increases:1
  • Coronary heart disease
  • Type 2 diabetes
  • Cancers (endometrial, breast, and colon)
  • Hypertension (high blood pressure)
  • Dyslipidemia (for example, high total cholesterol or high levels of triglycerides)
  • Stroke
  • Liver and Gallbladder disease
  • Sleep apnea and respiratory problems
  • Osteoarthritis (a degeneration of cartilage and its underlying bone within a joint)
  • Gynecological problems (abnormal menses, infertility)
*Overweight is defined as a body mass index (BMI) of 25 or higher; obesity is defined as a BMI of 30 or higher.

The terms "overweight" and "obesity" refer to body weight that’s greater than what is considered healthy for a certain height.
The most useful measure of overweight and obesity is body mass index (BMI). BMI is calculated from your height and weight. For more information about BMI, go to "How Are Overweight and Obesity Diagnosed?"


Overview

Millions of Americans and people worldwide are overweight or obese. Being overweight or obese puts you at risk for many health problems. The more body fat that you have and the more you weigh, the more likely you are to develop:
  • Coronary heart disease
  • High blood pressure
  • Type 2 diabetes
  • Gallstones
  • Breathing problems
  • Certain cancers
Your weight is the result of many factors. These factors include environment, family history and genetics, metabolism (the way your body changes food and oxygen into energy), behavior or habits, and more.
You can't change some factors, such as family history. However, you can change other factors, such as your lifestyle habits.
For example, follow a healthy eating plan and keep your calorie needs in mind. Be physically active and try to limit the amount of time that you're inactive.
Weight-loss medicines and surgery also are options for some people if lifestyle changes aren't enough.

Outlook

Reaching and staying at a healthy weight is a long-term challenge for people who are overweight or obese. But it also is a chance to lower your risk for other serious health problems. With the right treatment and motivation, it's possible to lose weight and lower your long-term disease risk.
