My mum is type 1 and regularly gets a number of high blood-sugar tests often followed by a number of low blood-sugar tests even though her diet, insulin injections and exercise program is remain the same. We’re trying to find the cause of this so that she can better manage her diabetes. We found out that cortisol is the body’s stress hormone and that it raises the glucose level in the blood. Mum does get very stressed so maybe this provides a partial explanation of what’s happening. Is there anything that can explain her unusually high tests, or is there anything that can be done to moderate her stress levels or the levels of cortisol? Any suggestions would be most welcome.
