Final answer:
Glucose may appear in the urine as a result of uncontrolled diabetes, causing a condition called glucosuria. This is one of the early manifestations of diabetes and can be accompanied by symptoms such as frequent urination and excessive thirst.
Step-by-step explanation:
Normally, there is no glucose in urine. However, glucose may appear in the urine as a result of uncontrolled diabetes. In diabetes, the cells are incapable of utilizing glucose, causing the blood glucose level to increase.
As a result, there is an increased excretion of glucose in the urine, leading to a condition called glucosuria. This is one of the early manifestations of diabetes and can be accompanied by symptoms such as frequent urination and excessive thirst.
