The Truth About Urine (cont.)
When you notice that your urine has changed color, or there's a strange odor wafting up from the toilet, the cause might be something as harmless as what you had for dinner (which could have included beets or asparagus). It also might be a sign of a more serious condition, such as an infection or cancer.
Before you flush, here are a few urine changes to look out for, and what they might be saying about your health.
Urine gets its yellow color from a pigment called urochrome. That color normally varies from pale yellow to deep amber, depending on the concentration of the urine. Darker urine is usually a sign that you're not drinking enough fluid. "Your body needs a certain amount of fluid to function, so the body will hold on to fluid and the urine will become very strong and concentrated. When that happens, it will turn a darker color," Griebling says.
The opposite is also true. If your urine is very pale, it means that you're
either drinking a lot of fluid, or you're taking a
Urine can turn a rainbow of colors, and an unusual hue isn't necessarily cause for alarm. Certain medications can turn the urine fluorescent green or blue, carrots can tint it orange, vitamins can give it a yellow hue, and an inherited disease called porphyria can shade it the color of port wine.
Seeing red is typically a sign that there is blood in the urine, but before you panic, know that a little blood can produce a dramatic color change. "What I always tell patients is it takes one drop of blood to turn a toilet bowl red," Smith says.
That said, just a little blood in the urine can be a sign of something serious, like an infection or cancer, and it warrants a visit to your doctor or urologist. If you're seeing blood and your urine is also cloudy, there's a good chance you've picked up an infection, Smith says.
Urine normally doesn't have a very strong smell. If you get a whiff of something particularly pungent, you could have an infection or urinary stones, which can create an ammonia-like odor. Diabetics might notice that their urine smells sweet, because ofexcess sugar. In the past, doctors would actually taste urine for this sweetness to diagnose diabetes.
Some foods can also change urine odor. Asparagus is among the most notorious. What people are smelling when they eat asparagus is the breakdown of a sulfur compound called methyl mercaptan (the same compound found in garlic and skunk secretions). If you catch a whiff of something after eating a plate of asparagus, it means that you've inherited the gene for the enzyme that breaks down mercaptan. Not everyone has this enzyme and, therefore, not everyone can smell it.
How Often Do You Need to Go?
How often you need to go can be as important an indicator of your health as the color or smell of your urine. Most people take bathroom breaks about six to eight times a day, but you might go more or less depending on how much fluid you drink. If you're constantly feeling the urge to go and it's not because you're not drinking extra fluid, causes can include:
