Question from Seattle, Washington, USA:
My college aged son has had type 1 diabetes since age 4. He has been on insulin pump therapy for over 10 years. His A1cs usually are 6.5 to 7.5. He is active and has generally good health. This fall, his A1c has gone up to above 8, and he has had a problem that appears unrelated to the diabetes; he has developed several cysts (testicular, earlobes, soft tissue). He sees an endocrinologist for his diabetes care quarterly, but when away at college, goes to the general practitioner (GP) at student health. The GP had a testicular cyst ultrasound done and they determined it was nothing to worry about. Now, with the other cysts popping up, and a higher than usual A1c, I am worried there could be some underlying cause, such as an infection or cancer. He can't get in to see his endocrinologist until March. Is there any urgency to this situation? Is there any known connection between cysts and type 1? My son is very independent. I am asking just to offer him more information so he can decide what additional check up, if any, he needs.
