Explain the amount of Glucose in Urine
Detectable amount of glucose is only found in the urine when the blood level exceeds a certain threshold value i.e., 180 mgI100 ml. In untreated diabetes mellitus, the blood level will exceed this value, especially after a carbohydrate meal. The result is that the glucose appears in the urine. This condition is called plycosuria. If the patient is treated with insulin, then also glucose may appear in the urine because some residual urine is left in the bladder. Higher the blood sugar level, greater the glycosuria.
