Cortisol
Cortisol is the body's primary stress hormone, and chronically elevated levels can promote belly fat storage and increased appetite.
Plain English
Patient-Friendly Explanation
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.

Clinical Definition
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.
Key Insight
Why It Matters
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.
