Dr Amir Khan has issued a warning about the long-term health effects of stress, particularly its potential to increase the risk of developing type 2 diabetes. The ITV doctor explained in a social media video how chronic stress can create a biological environment conducive to insulin resistance.
The Link Between Stress and Diabetes
According to Dr Amir, stress triggers the release of cortisol, a hormone that historically helped humans survive threats by releasing stored energy. However, in modern life, constant worries about work, finances, or family keep cortisol levels elevated. This persistent elevation tells the liver to release more glucose into the blood, prompting the pancreas to produce extra insulin. Over time, cells become less responsive to insulin, leading to insulin resistance—a precursor to type 2 diabetes.
Dr Amir emphasized that stress does not directly cause diabetes overnight but can create the perfect conditions for it, especially when combined with poor sleep, inactivity, and weight gain.
Cortisol's Role in Cravings and Weight Gain
He further noted that cortisol increases cravings for sugary, fatty foods and encourages fat storage around the abdomen, all of which worsen insulin resistance. Managing stress, therefore, is not just about mental well-being but also metabolic health.
Support from Diabetes UK
Diabetes UK supports this view, stating that stress hormones make it harder for insulin to work, raising blood sugar levels and increasing the risk of complications. The charity advises managing stress to protect both mental and physical health.
