Most changes in urine odor are temporary and don't mean you have a serious illness, particularly if you have no other symptoms. When an unusual urine odor is caused by an underlying medical condition, other symptoms are also present. If you're concerned about the odor of your urine, talk to your doctor.
Cystitis
It's often caused by a bacterial infection, such as a UTI. The bacteria from the infection can result in a strong fish smell in the urine.
If you detect a hint of ammonia in your urine, it could be a sign of a urinary tract infection (UTI). The odor suggests that bacteria may be swimming around in your urinary system, most likely in your urethra, kidneys or bladder. Urine showing signs of a UTI also may be cloudy or even a bit bloody.
Dr. Kaaki says the number one reason for bad-smelling urine is dehydration. “You always have a certain amount of ammonia in your urine. When you have more water, the ammonia is diluted, and it smells less intense.
Pee smells different when there's less water and/or more waste. Certain foods, medications, and dehydration can cause smelly pee. Less commonly, smelly pee might be due to a health condition, like a urinary tract infection or diabetes. Smelly pee is common and rarely a cause for concern.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
Regular urine color ranges from clear to pale yellow. But certain things can change the color. Foods such as beets, blackberries and fava beans can turn urine pink or red, for example. And some medicines can give urine vivid tones, such as orange or greenish-blue.
The following conditions can sometimes cause smelly urine, but they are uncommon: urinary stones – these may cause an ammonia-like odour (read about bladder stones and kidney stones)
Chronic kidney disease (CKD) is one possible cause of having an ammonia taste in your mouth, sometimes called “ammonia breath.” Some people describe ammonia breath as having a metallic taste, while others have reported that it smells similar to urine.
If you have diabetes insipidus, you'll continue to pee large amounts of watery (dilute), light-colored urine when normally you'd only pee a small amount of concentrated, dark yellow urine.
Diabetes can cause cloudy urine when too much sugar builds up in your urine. Your urine may also smell sweet or fruity. Diabetes can also lead to kidney complications or increase risk of infections of the urinary tract, both of which can also make your urine appear cloudy.
But there are two colors that you must take seriously: red and dark brown. Pink or red urine means red blood cells are present in urine. These colors may be a sign of infection, kidney stones or even cancer.
Light-brown or tea-colored urine can be a sign of kidney disease/failure or muscle breakdown.
The most common symptoms of UTIs include changes in urination such as frequency, pain, or burning; urine looks dark, cloudy, or red and smells bad; back or side pain; nausea/vomiting; and fever. Antibiotics are used to treat UTIs.
Foamy, frothy or bubbly urine.
“Diabetes starts as a silent disease, advancing painlessly, almost imperceptibly,” says Dr. Ferrer, who sees 25 to 30 diabetic patients per week. “It mainly attacks the small blood vessels, damaging the kidneys, eyes, and nerves.” It can also affect larger blood vessels.
This coloring is primarily caused by the pigment urochrome, also known as urobilin. Whether your urine is diluted by water or in a more concentrated form determines the appearance of the pigment. The more water you drink, and the more hydrated you become, the lighter the pigment in your urine.
Bright yellow urine is a sign of excess B-vitamins in the body, including B-2 and B-12, although this condition is harmless. Taking B-vitamin supplements can lead to urine of this color. The yellow color darkens as the concentration of the urine increases. Concentration refers the proportion of waste products to water.
