Obesity: Understanding

Obesity: Overview

Obesity is a chronic, relapsing, adiposity-based disease characterized by excessive or abnormal body fat that can impair physical health and increase morbidity and mortality. Traditionally, obesity in adults is defined using BMI >=30 kg/m2, although newer frameworks emphasize that BMI alone does not capture fat distribution or obesity-related organ dysfunction. Central adiposity, excess body fat and associated complications are increasingly incorporated into diagnosis.

Common signs and symptoms include excess body weight, increased waist circumference, breathlessness, fatigue, reduced physical mobility, joint discomfort and sleep disturbances. Obesity is multifactorial and results from interactions among genetic susceptibility, energy imbalance, dietary patterns, physical inactivity, environmental factors, medications, socioeconomic conditions and neuroendocrine regulation.

Pathophysiologically, obesity develops when energy intake chronically exceeds energy expenditure, resulting in adipocyte enlargement and expansion of adipose tissue. Excess adiposity can promote chronic low-grade inflammation, insulin resistance, altered adipokine signaling and metabolic dysfunction, contributing to type 2 diabetes, cardiovascular disease, fatty liver disease, sleep apnoea and musculoskeletal disorders.

Diagnosis of obesity begins with assessment of body mass index (BMI), with a BMI >=30 kg/m2 generally classified as obesity in adults; however, BMI alone does not accurately reflect body-fat distribution or health risk. Waist circumference is therefore often measured to identify central or visceral adiposity, while body-composition techniques such as DXA or bioelectrical impedance may be used when additional assessment is required.

Clinical evaluation includes medical and family history, weight trajectory, diet, physical activity, medications, sleep, and potential secondary causes such as endocrine disorders. Clinicians also assess obesity-related complications through blood pressure measurement and laboratory tests such as glucose/HbA1c, lipid profile and liver-function tests. Increasingly, diagnosis emphasizes the amount and distribution of excess adiposity together with its impact on organ function and overall health, rather than relying on BMI alone.

Treatment is individualized and aims not only to reduce weight but also to improve obesity-related complications and overall health. Lifestyle management, including nutritional intervention, physical activity and behavioral support, remains foundational; however, long-term physiological adaptations can make sustained weight loss difficult. Pharmacotherapy may be added when clinically appropriate, with current options including GLP-1 receptor agonists and GLP-1/GIP-based therapies such as semaglutide and tirzepatide, alongside other approved anti-obesity medicines. For selected patients with severe or complicated obesity, metabolic/bariatric surgery provides the most durable weight-loss option.

Report Highlights:

• In August 2026, Neurocrine Biosciences, Inc. announced the initiation of a Phase I first-in-human clinical study evaluating the safety and tolerability of NBIP-'1968, an investigational GLP-1/GIP/glucagon receptor triple agonist being developed as a therapy for obesity.

• In March 2026, Viking Therapeutics, Inc. announced the completion of patient enrollment in its Phase III VANQUISH-2 clinical trial of subcutaneous VK2735, the company's dual agonist of the glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors. VK2735 is being developed in both oral and subcutaneous formulations for the potential treatment of metabolic disorders such as obesity.
• In January 2026, Alveus Therapeutics Inc. announced its launch with a USD 159.8 million Series A financing. Proceeds from the financing will support Phase II clinical development of ALV-100, the company's lead program.
• In January 2026, Roche announced positive topline results from CT388-103, a Phase II clinical trial of CT-388, an investigational dual GLP-1/GIP receptor agonist being developed for the treatment of obesity.
• In January 2026, Alveus Therapeutics, Inc. announced that the US Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for ALV-100, the company's lead investigational therapy for chronic weight management, enabling initiation of a Phase Ib clinical study.
• In December 2025, Wave Life Sciences Ltd. announced positive interim data from the lowest therapeutic cohort of the ongoing first-in-human INLIGHT trial evaluating WVE-007 for the treatment of obesity. In this interim assessment, a single 240 mg dose of WVE-007 led to an improvement in body composition characterized by reductions in total and visceral fat mass at three months and an increase in lean mass. There was also a favorable safety profile as well as durable reductions in serum Activin E that support potential once or twice-yearly dosing.
