Final answer:
Normal urine is clear and transparent, but it can become milky due to red due to blood, or greenish-yellow with bile pigments. The presence of ketone bodies can give a fruity odor to urine in diabetic patients.
Step-by-step explanation:
Normal urine is typically clear and transparent. However, certain conditions can alter its appearance. For instance, milky urine might indicate the presence, which can signify an infection. Urine with a red hue usually suggests the presence of blood, which could indicate a urinary tract infection, kidney stone, or a more serious condition like cancer. If the urine has a greenish-yellow color, it might contain bile pigments or be affected by certain foods, medications, or conditions. Urine that appears cloudy instead of clear could be due to the presence of white blood cells, another indicator of a possible urinary tract infection.
The odor of urine also provides clues about health. Normal urine has an aromatic odor but can emit a fruity odor in diabetic patients, due to the excretion of excess ketone bodies like acetone in the urine.
