What is the life span after being diagnosed with obesity?

Obesity is a major risk factor for a number of chronic diseases, including heart disease, stroke, type 2 diabetes, and some types of cancer. These diseases can all lead to premature death.

The exact life expectancy of a person with obesity depends on a number of factors, including their age, sex, overall health, and the severity of their obesity. In general, however, people with obesity can expect to live about 10 years less than people who are not obese.

For example, a study published in the journal JAMA Internal Medicine found that the average life expectancy of a 40-year-old white man with obesity was about 67 years, compared to about 77 years for a 40-year-old white man of normal weight.

Another study, published in the journal The Lancet, found that the average life expectancy of a 50-year-old woman with obesity was about 71 years, compared to about 82 years for a 50-year-old woman of normal weight.

The good news is that losing weight can help to reduce the risk of developing these chronic diseases and improve life expectancy. Even losing a small amount of weight can make a big difference. For example, a study published in the journal Obesity found that losing just 5% of body weight can reduce the risk of developing heart disease by 25%.

If you are obese, talk to your doctor about ways to lose weight and improve your health. There are a number of effective weight loss treatments available, including diet, exercise, and medication.
