Urinary glucose - Definition

Ask a question


Glucose is a simple sugar used as the primary energy source in the body's cells. Normally there is no glucose in the urine, or in very small quantities. Urinary glucose is detected with a strip: it is called glycosuria. The presence of glucose in urine is caused by hyperglycemia, elevated glucose levels in the blood where, when a glucose threshold is exceeded, the reabsorption capacity of the kidney can no longer prevent the escape of a part of blood glucose. The urinary glucose can be a way of discovering diabetes, or mark the existence of poorly controlled diabetes.
