Sugars A high level of glucose and other sugars in the urine (glycosuria) is often a symptom of diabetes mellitus.

It leads to excretion of glucose in the urine. Due to a lack of the hormone insulin, plasma glucose levels are above normal.
Ad. Another cause for glucose in the urine is a condition known as renal glycosuria.
