Why does urine have an odor? Different odors have different causes.

Many people have the problem of urine with peculiar smell, but they don’t know that there are many types of urine with peculiar smell. If urine has different smells, then its inducing factors are also different.

1. Urine with ammonia smell . The volatile acid in normal urine will decompose urea due to bacteria or produce an ammonia smell after being left. If the urine has an ammonia smell as soon as it is discharged, it often indicates chronic cystitis and chronic urinary retention.

2. There is a 90% chance that foul-smelling urine is a sign of bacterial infection. It could be E-COLI bacteria, which can cause your urine to smell bad. It should be treated immediately and you should see a doctor as soon as possible.

3. Urine burning sulfur smell

The optimistic estimate is that you probably ate too much asparagus. The sulfur-containing amino acids in asparagus can give your urine this smell. This smell will fade away as the asparagus is fully digested. If the sulfur smell persists for more than two days, it is necessary to go to the hospital for a urine test.

4. Sweet fruity urine

If your urine smells like sweet fruit, it's not because you ate too much fruit salad. This odor in your urine is most likely due to a bacterial infection. The smell is released by acids called ketones in the blood as the body tries to get rid of glucose. If this situation is not taken seriously, it may pose a threat to your life. The urine of some diabetic patients contains a lot of sugar, which attracts some sweet-loving insects. Therefore, the urine of diabetic patients often smells like sweet fruit.

5. Caramel flavor

If your urine has a strong caramel smell, then there is reason to suspect that you may have maple syrup urine disease. Maple syrup urine disease is a rare genetic disease that occurs in only one in 225,000 people. People with maple syrup urine disease often cannot metabolize protein properly, which is why their urine smells like caramel.
