It can be alarming to see red blood color of urine in the bowl, or green, blue, cloudy, or frothy liquid coming out of your body. Most of the time, however, there is a non-threatening explanation for the urine that comes in all the colors of the rainbow.

Experts tell us that a healthy body of urine is straw colored. It’s just a little yellow and transparent. From time to time, however, urine comes in different colors. In general, strange-colored urine is benign in origin, but occasionally it is a sign that it is time to go to the doctor.

Yellow Urine Straw

Healthy urine is 96 percent water, with just a few other waste products. The body excretes an acidic compound called urea when excess amino acids have to be converted to sugar. The sugar remains in the body, and urea, otherwise it causes the blood’s pH to drop.

Urea itself is colorless. The small amount of yellow pigment in the healthy urine is a compound called urochrome, it is made from recycled bile salts. Bile is a liquid produced by the liver to dissolve the fats in the digestive tract. Excess bile salts are eliminated in urine and feces.

If you put urine in a bottle, you should be able to see its true color if you return a white paper or a newspaper. If your urine is dark, it is possible that you are not drinking enough water.

Completely Clear Urine (Clear)

If the urine is completely clear, it is usually the result of excess water being drinking. Athletes who drink lots of water during sports competitions, for example, and people in the ten-cup water tables daily tend to have clear urine. Clear urine usually only means that the urochrome is so diluted that it is not visible. If you stop drinking so much water, and it returns to normal color.

Clear urine is also common in people who take diuretics, in general, for high blood pressure or edema. When the medication is stopped, it returns the color. The doctor will probably carry a urine sample as part of regular health surveillance.

In rare cases, clear urine can result from diabetes insipidus, the pituitary gland’s failure in the brain to make a substance called antidiuretic hormone. This is caused by an injury to the brain or certain metabolic conditions. The kidneys do not get the message to keep it in the middle of the night, so sleep becomes difficult, and dehydration, despite the clear urine, is a constant concern. This condition increases thirst as it increases urination, but it is very difficult to keep up with the hyperactivity of the kidneys for the day. Diabetes insipidus is diagnosed by depriving the patient of water, which should not decrease urine production, as much as expected the opposite.

Urine orange

Orange urine can be dyed by beta carotene, the most generous antioxidant compound in carrots. People who consume large amounts of carrots may have orange urine. Orange urine can also be a sign of hepatitis, as inflammation in the liver makes bile to travel directly to the kidneys. However, dehydration is the most common cause of orange urine. The kidneys work all night long, when they do not lift me to drinking water, and keep urochrome elimination (mentioned above) without removing the water to dilute.
