|
|
When glucose levels are abnormally high, the blood becomes saturated with glucose and it is excreted by the kidney.
|
|
|
The kidneys actively add glucose to the urine when its levels are high to replace the insulin that is normally excreted.
|
|
|
The lack of insulin prevents its targets in the kidneys from being stimulated to absorb glucose
|
|
|
The abnormally high levels of glucose in the blood results in are counterbalanced by a high release of insulin from the pancreas and then released in the blood.

Detailed explanation-1: -Diabetes causes glycosuria because there either isn’t enough insulin, or your body can’t use what’s available. WIthout insulin, blood glucose levels become too high, and your kidneys can’t filter and reabsorb it. Your body gets rid of the excess through your urine.
Detailed explanation-2: -If you have a normal level of blood glucose with a high level of glucose in your urine, it may be a sign of an uncommon kidney condition, such as renal glycosuria or Fanconi syndrome. An increase in urine glucose doesn’t always mean you have a medical condition that needs treatment.
Detailed explanation-3: -In conditions when blood sugar is extremely high, the kidneys, in their effort to lower blood sugar levels, prevent the reabsorption of glucose back into the blood. This results in the presence of glucose in urine.
Detailed explanation-4: -Renal glucosuria is the excretion of glucose in the urine in detectable amounts at normal blood glucose concentrations in the absence of any signs of generalized proximal renal tubular dysfunction due to a reduction in the renal tubular reabsorption of glucose.
