Thanks for the info - I think you are correct about the stress/hormone(insulin) being the cause. Alec's nurse got back to me - here is what she said.
Complaint of hair loss isn’t
uncommon soon after diagnosis. There are three things we look at and most
often it is the last of the three. First is thyroid function, because
hair loss can be one of the many symptoms that you would see if the function is
off. Luckily we have already screened his thyroid function and antibodies
and both were fine. The next is Zinc deficiency, which can occur if diet
isn’t up to snuff. We can test a Zinc level if the hair loss
continues for a long period of time. The third and most common is the
post stress effect of diagnosis and initial treatment of diabetes. A colleague
described it as similar to post pregnancy hair loss and the cellular regrowth
rate that occurs after the huge change in the bodies hormone levels (Insulin is
a hormone). This does resolve after a while but it can take several
months. We get more concerned if there are huge clumps of hair, which
would be more indicative of thyroid or Zinc (or alopecia-general hair loss).
I am truly happy it seems to be not such a big deal. I hope you and yours are doing good.
