Cortisol

Cortisol is your body’s main stress hormone, released when you are under pressure. While it helps you handle short-term challenges, chronically high cortisol levels can increase appetite, promote belly fat storage, and make weight loss much harder.

Cortisol is a glucocorticoid hormone produced by the adrenal cortex, regulated by the hypothalamic-pituitary-adrenal (HPA) axis. It plays a key role in glucose metabolism, immune function, and the stress response. Chronically elevated cortisol promotes lipogenesis in visceral adipose tissue, increases cravings for high-calorie foods, and induces muscle catabolism.

Understanding the role of cortisol helps explain why stress management and sleep quality are just as important as diet and exercise in a weight-loss programme. Dr Wang assesses these factors as part of a comprehensive weight management plan at Accord Medical.
