| Hi Gaelicgirl,
Welcome (I also wish it was under better circumstances, but this is a great place for info and support).
My father and my sister are type 1. My father was diagnosed in his early 30s and he was thin (dangerously thin). My sister was diagnosed at age 9. She had gained weight prior to her diagnosis, but was by no means overweight. Then she lost weight dramtically (but also grew about half a foot, so it seemed fairly normal). I am not even remotely a doctor or nurse, but I would say your hunch about your husband being type 1 could be right.
In my family's experience I would say it is good to be pro-active with doctors when it comes to diabetes. Ask questions, challenge them, push them and get as much info as you can. Good luck. Keep us posted. |
