Death rate from obesity, 2019. Obesity is a risk factor for many chronic physical and mental illnesses.. The health effects of being overweight but not obese are controversial, with some studies showing that the mortality rate for individuals who are classified as overweight (BMI 25.0 to 29.9) may actually be lower than for those with an ideal weight (BMI 18.5 to 24.9).

The obesity paradox is also relevant in discussion of weight loss as a preventative health measure – weight-cycling (a repeated pattern of losing and then regaining weight) is more common in obese people, and has health effects commonly assumed to be caused by obesity, such as hypertension, insulin resistance, and cardiovascular diseases. [26]
These diseases include coronary heart disease, stroke, cardiomyopathy, arrhythmia, and heart valve or heart chamber problems. Cardiovascular disease is the leading cause of death in the United States and worldwide. [3] [4] In the United States, cardiovascular diseases account for one out of four deaths. [5]
According to the Centers for Disease Control and Prevention, nearly 80 percent of adults and about one-third of children now meet the clinical definition of overweight or obese. More Americans live with “extreme obesity“ than with breast cancer, Parkinson’s, Alzheimer’s and HIV put together.
Metabolic syndrome can lead to several serious and chronic complications, including type-2 diabetes, cardiovascular diseases, stroke, kidney disease and nonalcoholic fatty liver disease. [ 11 ] Furthermore, metabolic syndrome is associated with a significantly increased risk of surgical complications across most types of surgery in a 2023 ...
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
Obesity hypoventilation syndrome is defined as the combination of obesity and an increased blood carbon dioxide level during the day that is not attributable to another cause of excessively slow or shallow breathing. [2] The most effective treatment is weight loss, but this may require bariatric surgery to achieve. [3]
Similar findings have been made in other types of heart disease. People with class I obesity and heart disease do not have greater rates of further heart problems than people of normal weight who also have heart disease. In people with greater degrees of obesity, however, the risk of further cardiovascular events is increased.
