Mine came about after some emotional trauma and a high stress situation. I'm convinced it had a lot to do with 'adrenal fatigue' a subject that's getting more air time now but not when i was diagnosed, it leads to all types of hormonal issues, damage to the endocrine system, too much cortisol in the body, lack of seretonin. We live in a society that is plagued by chronic stress. I heard on bbc radio 4 recently that advertisers used to use sex to sell products, this has now changed dramatically, and now they use 'terror' as their new marketing strategy, 'terror' sells. So we are all placed into an environment where we are subjected to high level of chronic stress. I see an increase in people globally becoming diabetic and the news getting more dramatic and charged with wall to wall war journalism, violence and other pretty nasty business. Now i tend to turn the news off and look for things that will lower my stress levels, so i use self hypnosis cds, and positive affirmation techniques, i could go on. So what causes diabetes? ... imo... just being human, toxins in the environment, the flaws in our genetic make up, globalization, the food we eat, a predisposition to high anxiety influenced by an Orwellian dystopia, the immorality of pharmo companies, oh... and global warming and hairdressers
