my friend is 50 years old, male, had gall bladder removed in 1998...he is suffering from headaches, pain in the stomach, shortness of breath, increased heart rate, reduced urine output, has puffy hands and face. has a bit of a fever...he doesn t drink much at all, he only takes vitamins daily and sometimes a Tylenol. he does not smoke and has no allergies. he has been told thru a urine test that his urine contains protein and glucose, and his maternal grandmother had diabetes....is it possible he is diabetic??? please let me know what you think. thank you
