Wow, you must have a good memory, @Shaz51, if you can think back to all the members in a thread. I lose track and mostly have to go back and check each page when doing multiple tags. I usually only tag those that have recently been in the discussion but trust that members will jump in and join the discussions if they want to. I thought you must make lists of names or something like that! 
Hi @Shaz51, and others here who have responded to this question about diabetes.
When under high levels of stress or anxiety we release Cortisol. Cortisol is known as the stress hormone, and is released during fight or flight responses to danger, stress, etc. If these levels are maintained over a long period, it can lead to a number of serious health issues.
Cortisol is an important and helpful part of our body’s natural response to stress, however it’s important that the body’s functions are returned to normal as quickly as possible following a stressful event. If our body’s stress response is activated so often that the body doesn’t have a chance to return to normal, it results in chronic stress.
High and prolonged levels of cortisol in our bloodstream have a number of negative effects. This includes: insulin resistance, blood sugar imbalances, cholesterol issues, impaired cognitive performance, suppressed thyroid function, decreased bone density and muscle tissue, blood pressure issues, lowered immunity, increased body inflammation, increased risk of heart and cardio vascular diseases, etc. So its important to continually monitor your blood sugar, cholesterol, thyroid, BP, etc.
And from all this you need to remember that its better for your husband to have his anxiety treated, than to not. Left untreated he has an increased propensity to develop insulin resistence which is a precurser to type 2 diabetes.
I was diagnosed with pre-diabetes, with insulin resistence, a little over a year ago. I do not have any of the typical danger signs - I'm actually under my ideal weight, there is no family history of diabetes, I consume very little sugar in my diet, etc. My GP said it is highly likely that extended periods of high anxiety is what has caused the insulin resistance and pre-diabetes. Normally people who are pre-diabetic are told to lose weight and exercise more. For me that isnt possible, so I need to concentrate harder on reducing stress.
Hope his helps.
