Obesity

Chronic disease characterized by excess body fat sufficient to impair health, defined in adults by BMI >=30 kg/m².

Classes I (30 to 34.9), II (35 to 39.9), and III (>=40, morbid). Drivers are multifactorial: genetic, environmental (obesogens, food environment), behavioral, hormonal (leptin, ghrelin), and medication-related. Treatment combines lifestyle intervention, pharmacotherapy (GLP-1 receptor agonists), and bariatric surgery. Comorbidities include T2DM, CVD, NAFLD, OSA, and several cancers.
