What is Obesity

Obesity is a chronic, multifactorial disease defined by excessive accumulation of body fat due to an imbalance between caloric intake and energy expenditure. Its development results from complex interactions among genetic predisposition, environmental factors such as high-calorie diets and sedentary lifestyles, and behavioral influences. Key pathophysiological mechanisms include dysregulation of appetite-controlling hormones, neuroendocrine signaling abnormalities in the hypothalamus, insulin resistance, chronic low-grade inflammation, and altered secretion of adipokines. Obesity can be classified into primary (essential) obesity, secondary obesity due to identifiable medical or pharmacological causes, monogenic and syndromic forms linked to genetic mutations, and childhood obesity, which carries additional long-term risks. Clinically, obesity increases the risk of numerous comorbidities, including type 2 diabetes, cardiovascular disease, hypertension, dyslipidemia, certain cancers, obstructive sleep apnea, and osteoarthritis, and may significantly reduce quality of life. Diagnosis is primarily based on body mass index (BMI), with a BMI of 30 kg/m² or higher indicating obesity in adults. Additional assessments such as waist circumference and laboratory tests help evaluate associated metabolic risks and identify secondary causes. Management includes lifestyle modification, pharmacotherapy (e.g., semaglutide, tirzepatide, liraglutide, orlistat, bupropion/naltrexone, phentermine/topiramate, lorcaserin), and, in selected cases, device-based interventions like implantable gastric stimulators, aiming to reduce weight and mitigate health risks.

Targets for Obesity

Targets in Clinical or Later Phases of Development

Target Name Gene Symbol
5-hydroxytryptamine receptor 2C HTR2C
glucagon like peptide 1 receptor GLP1R
glucagon receptor GCGR
fatty acid synthase FASN
epidermal growth factor receptor EGFR
diacylglycerol lipase alpha DAGLA
carbonic anhydrase 2 CA2
Glutamate Receptor Ionotropic AMPA Receptor
gastric inhibitory polypeptide receptor GIPR
Carbonic Anhydrase (nonspecified subtype)

Obesity is driven by a complex interplay of central and peripheral mechanisms regulating appetite, energy metabolism, and nutrient absorption. Key therapeutic targets include central appetite regulators such as the 5-hydroxytryptamine receptor 2C (HTR2C), which modulates serotonin-mediated satiety, and opioid receptors (OPRK1 and OPRM1), which influence reward-driven feeding. Additional central targets like hypocretin receptor 2 (HCRTR2) and trace amine associated receptor 1 (TAAR1) affect arousal, motivation, and energy balance. Peripheral hormone receptors, including glucagon like peptide 1 receptor (GLP1R), gastric inhibitory polypeptide receptor (GIPR), and glucagon receptor (GCGR), control insulin secretion, glucose homeostasis, and satiety. Enzymes involved in lipid metabolism, such as fatty acid synthase (FASN), diacylglycerol lipase alpha (DAGLA), pancreatic lipase (PNLIP), and gastric lipase (LIPF), regulate fat synthesis, breakdown, and absorption, directly impacting energy intake and storage.
