Ketones form in the body when blood sugar levels are too high. The body releases these ketones in the urine, which may change its smell. People are likely to experience a sulfur smell in their urine along with other symptoms such as excessive thirst, tiredness, and mood swings.
Urinary Tract Infections (UTIs)
If your urine smells like sulfur, urinary tract infection can be the culprit. The urinary tract consists of bladder, kidneys, and urethra, and any bacterial, fungal, or parasitic infection in these areas can cause several complications, including a change in your urine smell.
Urine concentration: It's normal for urine to have a stronger odor first thing in the morning. After a night's sleep, urine is more concentrated and odorous as well as brighter yellow in color. Dehydration also increases urine concentration, causing stronger smelling urine.
See a GP if: You have smelly pee and: you need to pee suddenly, more often than usual, or during the night. you have pain or a burning sensation when peeing.
Liver disease and certain metabolic disorders may cause musty-smelling urine.
Diabetes does not generally cause strong-smelling urine. Uncontrolled diabetes can lead to urine that smells sweet or fruity.
Kidney disease causes chemicals in urine to become concentrated and to cause a smell resembling ammonia. Kidney dysfunction can also cause high bacteria and protein levels in the urine, which will contribute to a foul ammonia smell.
When you're dehydrated and your pee gets very concentrated, it can smell strongly of ammonia. If you catch a whiff of something really strong before you flush, it might also be a sign of a UTI, diabetes, a bladder infection, or metabolic diseases.
Eating a lot of protein
As a result, the ketone level in the blood will rise. When these ketones leave the body in the urine, the urine may smell sweet or similar to popcorn.
Drinking more water may help to dilute the sulfur compounds in the body and reduce the smell.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotten or decaying fish.
Foetor hepaticus is a feature of severe liver disease; a sweet and musty smell both on the breath and in urine. It is caused by the excretion of dimethyl disulphide and methyl mercaptan (CH3SH)2, arising from an excess of methionine.
Foods that convert to sulfur compounds in your body can make your urine smell rotten. This smell is commonly compared to rotten cabbage or rotten eggs and can come from eating asparagus, garlic, and onions. There are rare conditions that create a rotten smell, too. Trimethylaminuria.
Pee that smells like ammonia
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 that contains a lot of water and few waste products has little to no odor. If urine becomes highly concentrated — a high level of waste products with little water — your urine may have a strong ammonia odor.
Several vitamins, including vitamin B-6, can cause urine smell to change. Although a strong smell to your urine probably doesn't mean vitamin D toxicity, it may indicate that you are dehydrated, which can in turn be a sign of excess vitamin D. Strong-smelling urine could also indicate a urinary tract infection.
Make a solution of baking soda, peroxide and any dish detergent. The combination of the three is often powerful enough to drive away strong urine smells. The solutions is eight fluid ounces of peroxide, three tablespoons of baking soda, and a few drops of dish detergent.
Light-brown or tea-colored urine can be a sign of kidney disease/failure or muscle breakdown.
When the excess urea in your body reacts with saliva, it forms ammonia–which you then exhale through your breath. If you have CKD, this is what gives your breath that ammonia scent. The medical name for this is “uremic fetor”.
Transparent and lacking in color
Transparent, colorless urine could also be a sign of some other health disorders, including diabetes and kidney disease, or from taking diuretic medication.
Smelling of the breath is common after having certain food or in the morning, but with people suffering from fatty liver conditions, it remains throughout the day. The breath may have a distinct sulfur and musty smell throughout the day. It is an obvious sign of fatty liver disease and should not be ignored.
Urine that is dark orange, amber, cola-coloured or brown can be a sign of liver disease. The colour is due to too much bilirubin building up because the liver isn't breaking it down normally. Swollen abdomen (ascites).
One reason why your urine smells like eggs is that you have developed urinary tract infection. The odor is due to the parasites, fungi, or bacteria in your urine. The urinary tract includes your kidneys, bladder and urethra, and any of these organs can become infected and make your urine to smell like eggs.
