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.
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.
The meaning of other colors abnormal urine
Bright Yellow Urine
Sometimes the urine is bright, almost yellow “Neon”. In general, this is a result of taking vitamins nutritional supplements. The body can not store large amounts of vitamin B2, so it pours into the urine where it has a very noticeable color. As an isolated chemical compound, Vitamin B2 is more yellow orange, but because it also absorbs blue light, it has a bright and yellow appearance in the urine. Vitamin B2 is slightly soluble in water, so the color is generally sensitive first micturition after taking the supplement, in excess tends to be excreted at the same time.
If you have blue urine, the most likely explanation is that you have consumed foods made with blue dyes, such as icing or candy? The liver processes the staining and sends more or less directly to the kidneys excrete. Blue urine is also caused by the use of methylene blue, which is injected in the event of accidental cyanide poisoning or is used to treat urinary tract infections.
Urine of Green color
Green urine is most commonly a by-product of a type of bacteria called Pseudomonas aeruginosa. This bacteria lives in the gut, but can be transferred into the urinary tract when applied with a toilet paper moving forward instead of with a backward movement. Some people who have liver cancer may also have green urine, such as some people who drink large amounts of green tea. Green urine is sometimes observed after exposure to toxic substances.
Propofol anesthetic can make green urine as well as certain medicines for Parkinson’s disease.
Urine of Purple Color
Purple urine tends to be the result of a disease called porphyria, this affects about 30,000 people, mainly in the UK and South Africa. Porphyria was the cause of the “madness of the infamous King George III” of Great Britain, while now it can be treated.
Urine Red or Pink
Most people are alarmed by the urine of red in the basin. Sometimes discoloration is caused by plant pigments, particularly beet, but is most often due to bleeding in any part of the urinary tract. You need only 1 ml of blood to give the pink urine. Bleeding from the urinary tract can be caused by kidney stones, bladder or kidney blast, the in rare cases, bladder cancer.
Brown or Black Urine
Equally worrisome is the presence of brown or black urine in the vessel. Fortunately, it usually has a benign cause. Consumption of certain types of beans, especially beans or velvet beans, causes darkening of the urine due to its dopamine content. Certain medicines for Parkinson’s disease also, they have this effect, based on sena laxatives (in the United States and the United Kingdom, Sennecot) you can also darken the urine.
Blurred or White Urine
Turbid urine usually indicates a bacterial infection. When the urinary tract is infected, the immune system sends white blood cells to attack the germs. Some of them appear in the urine after awakening.
Men sometimes have dark or foamy urine after intercourse, or when they do not ejaculate for long periods of time. Semen can be in the urinary tract, and in the prostate, and may appear whitish or opaque in the urine.
It may be the result of the same white or cloudy urine causes, or may indicate excess protein from severely diseased kidneys. If kidney disease is the problem, there will be other symptoms besides foamy urine.
