Why would glucose show up in urine after large meal?

Glucose can appear in urine after a large meal due to a temporary increase in blood sugar levels that exceeds the kidney's reabsorption capacity. When blood glucose levels rise significantly, especially after consuming a meal high in carbohydrates, the kidneys may not be able to reabsorb all the glucose, leading to its excretion in urine. This phenomenon is often referred to as glucosuria and can occur even in individuals without Diabetes under certain circumstances, such as excessive carbohydrate intake.
