Overweight and Obesity

Health Consequences

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. For more, see Defining Obesity.
