The success of GLP-1 receptor agonists and dual incretin therapies has transformed obesity treatment. Therapies targeting GLP-1, GIP, and glucagon receptors are delivering unprecedented weight reduction outcomes compared to older therapies.
Expanding Awareness of Obesity as a Chronic Disease
Healthcare systems and medical societies increasingly recognize obesity as a chronic metabolic disease associated with major comorbidities including cardiovascular disease, diabetes, hypertension, and sleep apnea, driving greater treatment adoption.
Advancements in Precision and Combination Therapies
Emerging personalized approaches and multi-target metabolic therapies are improving efficacy, metabolic control, and long-term treatment outcomes while expanding therapeutic options for patients.

What is Obesity?
Obesity is a chronic, multifactorial, non-communicable disease characterized by excessive adiposity or body fat accumulation that adversely impacts health. It results primarily from an imbalance between energy intake and energy expenditure, influenced by environmental, psychosocial, metabolic, and genetic factors.
Diagnosis is generally based on Body Mass Index (BMI), calculated as weight in kilograms divided by height squared in meters. Obesity is associated with increased risks of cardiovascular disease, diabetes, hypertension, sleep apnea, metabolic syndrome, and several other chronic disorders.
