Hormonal

Gut hormone-based pharmacotherapies (GLP-1RAs, amylin analogues, and multi-agonists) produce clinically significant weight loss (≥10-15%) and improve cardiometabolic health, effectively closing the treatment gap between lifestyle interventions and bariatric surgery.

For individuals with obesity who have not achieved sufficient weight loss through lifestyle changes alone, gut hormone-based medications (like semaglutide or tirzepatide) offer a clinically effective treatment option that can produce 10-15% or more weight loss. These treatments work by targeting the body's natural appetite-regulating systems, mimicking the effects of bariatric surgery to a degree, and improving metabolic health. While side effects like nausea are common, they often subside with dose titration, and new oral formulations are emerging to address injection aversion.

GoodSupportsHIGH confidence
Scientific advancements have revealed the potential of therapeutic modification of gut peptides that modulate neural signalling involved in body weight regulation. The translation of the scientific understanding of body weight regulation has resulted in new anti-obesity medications that engender ≥10 % weight loss and are closing the treatment gap.
