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.
The reasons your urine has a strong odor include: -Foods, medications and vitamins can all potentially cause your urine to smell. For example, eating asparagus or pineapple can both change your urine's odor in different ways. -Dehydration can leave the urine more concentrated, so it takes on more of an ammonia-like smell. -Bacteria in the urine can give it a foul odor. This can be caused by a bladder infection or fistula (when an opening forms between the bladder and bowel). -What causes urine to smell sweet? This may be due to high blood sugar, and can be a sign of poorly controlled diabetes.
