Normally, urine that contains a lot of water has little to no odor. If your urine becomes highly concentrated â a high level of waste products with little water â urine odor may have a strong ammonia smell. Many foods and medications, such as asparagus or certain vitamins, can affect the odor of urine. Sometimes, unusual urine odor may indicate a medical condition or disease, such as: Bladder infection.
Urine doesn't typically have a strong smell, but if yours smells pungent (like ammonia), you could have an infection or urinary stones, or you may simply be dehydrated. Dehydration causes your urine to be more concentrated and may have a stronger smell than normal, as do high-protein foods like meat and eggs.
