Normal urine is generally pale yellow or colorless, but when there is a problem with human urinary organs or other systems, human urine can appear in different colors.
After standing for a period of time, bacteria decompose urea and produce the smell of ammonia. If the urine has a strong odor just after discharge, it may be caused by urinary tract infection.
Under normal circumstances, urine color changes will have related symptoms. Although the color of urine can tell us some diseases, we should not be alarmed when we see the change of color, because the color of urine is also related to diet and medication. The most common thing is that when eating a lot of carrots, the urine is yellow and bright; Taking rhubarb, a traditional Chinese medicine, can make urine dark yellow like strong tea.
