Freshly voided urine has very little smell, but shortly after voiding it can give off a very strong smell. Why?
What will be an ideal response?
Freshly voided urine is relatively sterile but if it is allowed to stand, bacteria begin to metabolize the urea solutes to release ammonia and other smells depending on the person's diet. A fruity smell generally means there is a diabetes problem.
