What is sugar in urine?
Sugar (glucose) is usually present in the urine at very low levels or not at all. Abnormally high amounts of sugar in the urine, known as glycosuria, are usually the result of high blood sugar levels. High blood sugar usually occurs in diabetes, especially when untreated.
Normally, when blood is filtered in the kidneys, some sugar remains in the fluid that will later become urine. If the level of blood sugar is low, as is normally the case, the body can reabsorb the sugar from this fluid before it leaves the kidney to be excreted as urine. When the blood sugar is high, there is too much sugar in the fluid leaving the kidney to be reabsorbed, so some sugar passes into the urine.
Sugar in the urine can be detected in the laboratory or is easy to detect at home with a urine dipstick test. Because sugar in the urine is associated with high blood sugar and diabetes, it is important to consult a physician if you suspect you have sugar in your urine. Sugar in the urine is often accompanied by other symptoms of diabetes, including fatigue, unexplained weight loss, excessive thirst or hunger, and frequent urination.
