In this condition the filters of the kidneys, the glomeruli, become damaged. Last week I had a doctors appointment. It ended with blood being drawn, urine being collected, and an exam that was one step away from a T&C (turn and cough). The last time I came in to see the doctor was over 6 months ago. I went in a couple of times for moments of sickness but I have not had a diabetes check up style appointment until now.
