Before I was diagnosed with diabetes, I actually had a bald patch appear on my head. I was mortified, even though my long hair covered it up. I was just told I was going through an early menopause.At that time, I was also told I had type 2 diabetes. I didn't and I wasn't going through the menopause either.I now know alopecia areata is an auto-immune disease, as is my Type 1 diabetes.
Hair loss can be very distressing but often it is just a temporary blip, as I hope yours will turn out to be. Although the bald patch never grew again,the rest of my hair is normal thickness and it's probably only me who is aware of my small smooth patch.
