A 35 years old man Ramu has fasting and post prandial blood sugar within normal limit but urine sugar is 3 plus (+++). The diagnosis is.: (A) Renal Glycosuria, (B) Pancreatic insufficiency, (C) Alimentary glycosuria, (D) High carbohydrate diet taken in the morning
Answer is A. Answer is A (Renal Glycosuria): 'Renal glycosuria' is characterized by urinary excretion of glucose at normal concentration of glucose in blood: Patient in question is testing positive for urinary glucose despite normal levels of both fasting and postprandial glucose in blood. This thus leads us to the diagnosis of renal glycosuria.
