Stress and blood sugar levels
People with type 2 diabetes are very sensitive to stress. It causes the body to produce especially high levels of stress hormones, which drive blood sugar levels up.
The effect of long stress on blood glucose levels is important. Repeated episodes of stress can cause serious changes in blood sugar levels, making it harder for diabetics to manage their condition and increasing the risk of hypoglycemia (too high blood sugar). Constant stress will also cause adrenal fatigue leading to adrenal failure, which is why it is vital to remove stress from your life, especially if you have diabetes.
