Death rate from obesity, 2019 Obesity is a risk factor for many chronic physical and mental illnesses. Because of the social stigma of obesity, people who are obese may receive poorer healthcare than people within the "normal" BMI weight range, potentially contributing to the relationship between obesity and poor health outcomes. People who experience weight-related discrimination, irrespective of their actual weight status, similarly have poorer health outcomes than those who do not experience weight-related discrimination. People who are obese are also less likely to seek medical care than people who are not obese, even if the weight gain is caused by medical problems. Some have proposed that obesity-associated medical conditions may be caused primarily due to stress from the social stigma of obesity, rather than from obesity per se. 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 to 29.9) may actually be lower than for those with an "ideal" weight (BMI 18.5 to 24.9). Health risks for those who are overweight may be decreasing over time as a result of improvements in medical care.
