Urine Smells and Burns and Want to Pee Again
Urine's Colors & Smells Prove an Indicator of Health
How's your pee been looking lately?
Information technology's not exactly polite conversation, but it'due south a question worth request yourself from time to fourth dimension. Just as the eyes are windows into the soul, urine is a window into the body.
Information technology tin reveal whether you're dehydrated, for instance, a common wellness issue during these sweaty summer months. Healthy urine consists of yellow waste products that are dissolved in h2o. Similar lemonade mixed from a pulverisation, the less water involved, the darker yellow (and more than pungent) the upshot, so dark yellow urine tells you you're due for a glass of water.
But to a doctor, urine tin provide even more information. One way for doctors to discover out what's going on inside the body is to examine what flows out of it. And so don't be surprised the next time a medico asks for a urine sample for a seemingly not-urinary complaint.
In fact, be a trivial proud. When you hand over that trivial loving cup, you lot're participating in a medical tradition more than half dozen,000 years in the making. [Related: The Fascinating History of Urine Tests]
Urine luck
Today's urinalysis can reveal a great deal about a person'due south heath. But fifty-fifty simple urine colour tin can tell people when to seek medical attention. Urine color may modify due to something as innocuous as medications or foods, or every bit malevolent as an infection or cancer.
Urine that appears pink or red from the presence of claret is one cause for alarm.
"If you see claret in the urine, even in one case, information technology requires you to see a doctor," said Marshall Stoller, a professor of urology at the University of California, San Francisco. "It could be nothing," he said, but "it could exist an early sign of a kidney rock or a cancer of some sort."
Red urine isn't the only indication of danger. "Sometimes the urine has a sort of Coca-Cola color," Stoller said. "It could be due to old blood from a tumor or kidney rock" or a blood clot in the kidney, which is more than mutual in people with sickle cell disease.
"Another reason that people could take that [cola] colored urine is when you accept someone who'due south being crushed," Stoller said. Vanquish injuries, like those sustained during earthquakes, cause muscle to suspension down, and bits of crushed tissue enter the bloodstream and are filtered into urine by the kidneys.
Liver impairment can also lead to brown urine, as can porphyria, an inherited blood disorder. And eating gargantuan quantities of fava beans or rhubarb tin can also turn urine nighttime dark-brown or black.
But not all abnormal urine colors are bad news. In fact, if you've eaten significant quantities of beets or blackberries, don't be surprised to observe yourself producing red or pink urine. Certain laxatives can likewise turn it red.
The same goes for orange urine, if you've been taking a urinary tract painkiller containing phenazopyridine, which can brand pee wait like Tang. Of medicines that touch on urine color, "that's the classic," Stoller said.
Methylene blue, part of some common medications for bladder discomfort, can plough urine blueish or green. And an glut of water-soluble vitamins tin can make urine announced brighter yellowish than normal.
Strange smells
An inherited condition, maple syrup urine illness, so named because it causes urine to odour similar sweet maple syrup, results from the body'south inability to assimilate certain amino acids. It's usually diagnosed in infants and treated with dietary restrictions, which must be started early in life to forbid encephalon damage and other bug. In many states, every newborn is tested for this disease.
Sweet-smelling urine can also signal diabetes mellitus, considering excess blood carbohydrate finds its way into the urine. And as medieval doctors knew, carbohydrate also affects urine's taste, but that's one diagnostic test they probably preferred to practice as piddling equally possible.
But that's not all. Asparagus is infamous for the stench it lends urine, which only some people can perceive.
In the lab
"I run into 100 patients a week. The odds of seeing patients with odd-colored urine is 1 percentage," Stoller said. Rather, most of the clues that doctors look for in urine, he explained, are invisible, detectable but in the urinalysis lab.
"There are dipsticks out that you tin can dip in the urine and identify the likelihood of infection," Stoller said. Urinalysis labs tin can also test for miniscule amounts of saccharide, blood, amino acids and other molecules, he said. They tin can put a number on urine's concentration, and screen for drugs. And by examining urine'south tiny crystals under a microscope, doctors can diagnose certain types of kidney stones.
Dehydration is the urinary consequence people are most likely to come across, Stoller said. And dehydration, though it sounds mundane, can become very serious very quickly, especially for the urinary system. "The trouble is when you concentrate the urine, things can go clogged upward," he said. "When kidneys become plugged upwardly information technology can issue in renal failure."
"The average adult needs about one and a half liters a day" of h2o, Stoller said. "And y'all desire to effort to pee nearly 1 and a half liters a mean solar day," he added, so "if yous sweat a lot you may need to potable substantially more."
