My brother, age 66, was diagnosed with Diabetes 2 about 6 weeks ago. His blood sugar at the time was over 600, and he had the usual symptoms. He was hydrated in the hospital and sent home with long and short acting insulins. His glucose levels have been lowering, and the doctors have been decreasing his insulin dosage. My brother was often experiencing low blood glucose at home. For the past 2 days, my brother has stopped taking his insulins, but he is still checking his glucose levels, and he says they are within the ranges the doctor gave to him. He has drastically changed his eating habits to stay under 75 carbs/day. My question is "could he have experienced short-term diabetes 2?" Although his blood glucose is within normal limits the past 2 days, he says he is urinating a lot.
