Could stress cause the appearance of diabetes?

Stress does not cause diabetes. You've probably had a chance to hear that in someone diabetes is detected after he was in stressful situations (such as infections, burns, surgery, etc., as well as mental stress). How to explain that? Immune reaction that leads to gradual destruction of pancreatic beta-cells that secrete insulin takes months, often years. Because of that in people who will get diabetes gradually is secreted less and less insulin and over time there is so much to maintain a satisfactory level of blood glucose only in normal conditions.

It was precisely because of that, in the stressful situation, when because of intensified secretion of hormones (adrenaline, cortisol), insulin requirements are increased, and its production becomes insufficient, first symptoms appear. On the other hand, although stress does not cause diabetes, it can significantly influence a disease control later. In stressful situations, because of intensified secretion of hormones, it leads to short-term increase in blood sugar levels, and often in changes of behavior (change of appetite or intensity of physical activity), which requires a change in dose of insulin (usually increase).
