This is usually not a good thing to have as it could tell you that your kidneys do not function as good as they should. This is something that is not dangerous to your life, but does need to be looked at because it tells you that your kidneys are weaker than they should be and might lead to other complications later in life.
Glycosuria happens when you pass blood sugar (blood glucose) into your urine. Normally, your kidneys absorb blood sugar back into your blood vessels from any liquid that passes through them. With glycosuria, your kidneys may not take enough blood sugar out of your urine before it passes out of your body.
