Just a thought--do your parents like this boy? Maybe there are other reasons for their dislike of this boy, because I guess I find it hard to believe someone would make you break up simply because they have diabetes. In fact someone as knowledgeable as your father would know that diabetes management has progressed as above mentioned.
And are these patients your father sees Type 2 diabetics? Type 1 diabetes is when the pancreas does not produce insulin. Type 2 diabetes is most often diagnosed in people who are overweight, do not exercise and have a history of neglecting the needs of their bodies. Therefore Type 2 diabetics still produce insulin but their bodies do not use the insulin sufficiently or I could say properly.
Anyway, why don't you try talking to your parents, maybe there was some miscommunication.
Hello, Mary. Of course people with diabetes can get married. Having diabetes is not a reason to avoid marriage. People with diabetes these days are doing much better with diabetes management, and the rate of complications in people who are using these management principles are dropping drammatically. 20 years ago, this wasn't the case, so the patients that your dad sees fall into that group, where they didn't have the tools and the knowledge that we have today. I'd have your significant other show that he can and does manage his diabetes well. Your parents need to understand that times have changed with respect to diabetes care, and there is no reason to break up with someone simply because of diabetes.
