which might indicate to a doctor that there is an issue with someones body chemistry?\n sugar in the blood\n…

Brief Explanations:

Normally, the kidneys re - absorb glucose from the filtrate back into the bloodstream. Sugar in the urine (glycosuria) can indicate that the body's normal regulatory mechanisms for blood sugar are not working properly, such as in diabetes where the body either doesn't produce enough insulin or is insulin - resistant, leading to high blood sugar levels that overwhelm the kidney's re - absorption capacity. Blood normally contains sugar (glucose) as a source of energy, and water is a normal component of both blood and urine.

Answer:

sugar in the urine
