Why does urine smell so bad?

Everyone excretes a certain amount of urine every day, and whether there is any disease problem in the body can also be judged by the color and smell of people's urine. If you observe carefully, you will find that many people have a strong odor in their urine. The reasons for this situation are quite complicated and may be related to people’s diet in daily life. In addition, we should also be careful about the role of disease. So why does urine have a strong odor?

1. Colorless urine

It may be a sign of diabetes, chronic interstitial nephritis, or diabetes insipidus. If it is not caused by drinking too much water, you should be careful to identify it.

2. White urine

White urine is common in purulent urine, chyluria and salt urine. Purulent urine is caused by severe purulent urinary tract infection, and the urine is milky white. Purulent urine is common in pyelonephritis, cystitis, renal abscess, urethritis, or severe renal tuberculosis. Chylous urine is one of the main symptoms of filariasis, and the urine is white like milk. Because the chyle (liquid after fat saponification) absorbed by the intestine cannot be drained into the blood circulation from the normal lymphatic vessels, it can only flow back into the lymphatic vessels of the urinary system, causing increased pressure in the lymphatic vessels in the urinary system, varicose veins and rupture, allowing the chyle to overflow into the urine, resulting in chyluria. Chylous urine is usually paroxysmal. When there are red blood cells in chyluria, it is called chylous hematuria. Microfilaria (i.e. young filaria) can sometimes be found in the blood and urine of patients with chylous hematuria.

3. Salt urine

It mostly occurs in children and is common in winter. If the urine is rice soup-like, it is usually because the original urine contains a large amount of phosphate or urinary hydrochloric acid, which is easy to precipitate after being left. If the urine is placed in a bottle and heated, it will immediately become clear. Salt urine is a normal physiological phenomenon. It can be cured without medication, the key is to drink more boiled water.
