Final answer:
Glucosuria, also known as glycosuria, is the condition indicating the presence of glucose in the urine and is associated with diabetes mellitus, where insulin dysfunction causes hyperglycemia.
Step-by-step explanation:
The condition that indicates the presence of glucose in the urine, a common symptom of diabetes mellitus, is known as glucosuria or glycosuria. This occurs when high blood glucose levels overwhelm the kidneys' ability to reabsorb glucose, leading to its excretion in the urine. In individuals with diabetes, impaired insulin function prevents glucose from being adequately absorbed by cells, causing hyperglycemia and triggering the excretion of glucose into the urine. Glucosuria is an important diagnostic marker for diabetes and is often accompanied by symptoms such as excessive thirst and frequent urination.
