J.S.
Bless your heart; I'm stunned the doc wouldn't test his blood sugar. I'm Type 1, diagnosed 40 years ago, and I've been on an insulin pump for the past 16 years (and doing well, knock on wood). I still remember my symptoms: I had what felt like a dry spot in the middle of my tongue, no matter how much water I drank (with frequent urination, which was classic ketoacidosis from high b.s.), and I wanted to sleep all the time. When my mom let me stay home from school, I'd awaken briefly when she left, then go back to sleep until 2 or 3pm, at age 11. I was weak and couldn't carry my books at school, and I'd have to rest on the stair landing to catch my breath. After a couple of weeks, mom took me to the doctor, and he diagnosed me right there during the office visit. Do you know anyone with a glucose meter? Have them use a new lancet, and test his sugar. If you don't know anyone, call the local drug store and see if they'll do it. On another topic, someone suggested checking the levels on his CBC, but that won't be reliable, because CBCs are taken from the vein, whereas blood sugar levels are taken from the finger (capillary). I've asked about that during my last dr. visit, and that's what the phlebotomist told me. Good luck!
