Why Glucose In Urine

Give 2 causes why blood glucose levels still fall in an untreated diabetic?
In an untreated diabetic person (i.e. lacking insulin) the blood glucose concentration after a meal reaches an abnormally high level. Eventually it slowly falls, however. Knowing that insulin is required for glucose uptake into liver, adipose, and muscle tissues, give two causes why blood glucose levels still fall in an untreated diabetic.
If I say, “a considerable amount of glucose gets collected in the urine (a condition known as glycosuria)”, is it good as one of the reasons? If not, please tell me the answers, if you know, to the question. Thanks a lot.
xonicjonas: I guess I should have posted my question in the biology category. It’s a question about my laboratory experiment, so I can’t use the answer you gave me.
Oh thought you did =)
“sugar in the blood”, “honey in the urine” is what happens
“Diabetes, known as diabetes mellitus, is a disorder caused by the body’s inability to break down certain substances, notably sugar. If the body is unable to transform or metabolize food into energy due to a lack of a protein hormone produced in the pancreas, the result is a high concentration of sugar in the blood and urine. ”
‘Banting and Best’ they found it in dogs and recreated diabetes. 1922 ?
It’s a short story…about two boys and their dogs LOL
