Question from Illinois, USA:
My 17 year old son has developed gynecomastia (requiring surgery to correct) since the onset of his type 1 diabetes. I have seen insulin use listed as a possible cause, but cannot get much information. Can this be related to insulin use?
Not to my experience, and I have seen literally thousands of boys with diabetes.
[Editor’s comment: Gynecomastia (breast enlargement in a male) is relatively common in teenaged males. Fortunately, it’s usually relatively mild, and although sometimes an emotional issue for teenagers (and their parents!), it’s rarely a medical problem severe enough to require surgery.
