Why would hypo secretion of insulin cause an increase in the amount of sugar in urine?

Hypo secretion of insulin leads to insufficient insulin levels in the body, which impairs glucose uptake by cells. As a result, glucose remains in the bloodstream, causing hyperglycemia. When blood glucose levels exceed the renal threshold, the kidneys cannot reabsorb all the excess glucose, leading to its excretion in urine. This process results in glycosuria, or the presence of sugar in urine.
