Medical experts define obesity as a complex, multifactorial disease

Medical experts emphasize that obesity is a chronic, multifactorial disease rather than a simple lack of willpower or excessive eating. The condition is driven by a complex interplay of genetic, biological, environmental, social, emotional, and economic factors, as well as sleep patterns and physical activity levels.

In the context of childhood obesity, specialists highlight that the family environment is a central component of treatment. It is difficult for children to adopt healthy habits if their surroundings—such as the availability of nutritious food or the presence of sedentary family behaviors—do not support change. Experts warn against stigmatizing children, noting that simplistic views can cause shame and guilt.

Clinical assessments often utilize the Body Mass Index (BMI) to categorize weight, though doctors note this must be interpreted alongside muscle mass and abdominal circumference. Obesity increases the risk of serious complications, including cardiovascular disease, type 2 diabetes, respiratory issues, sleep apnea, and certain cancers. Effective management requires personalized medical evaluation, balanced nutrition, and regular physical activity.
