What should I do if the urine color is yellow?

Check the following information by yourself;

Abnormal urine color can not only reflect the changes of urinary system diseases, but also reflect some lesions of other organs. If you pay attention to the urine of yourself and your family and go to the hospital for routine urine examination in time, you can diagnose some diseases as soon as possible.

Normal urine is light yellow and clear. If the urine shows abnormal changes such as red, brown, tan, milky white, green and black, it should be regarded as abnormal urine color. It is often suggested that people should go to the hospital in time because of certain diseases.

First, red urine

Most urine turns red because there are red blood cells in urine, which is called hematuria in medicine. Hematuria is often a signal of pathological changes in the urinary system and its adjacent organs. Red urine can be divided into hematuria, hemoglobinuria and purpura urine.

Hematuria is mostly caused by direct or indirect stimulation of urinary system (inflammation, ulcer, foreign body, drugs), or by renal congestion, blood vessel rupture and erythrocyte extravasation caused by tumor and congestive heart failure;

Hemoglobinuria often occurs after malaria, hemolytic transfusion reaction or eating fresh broad beans (some people can have bean diseases due to the lack of 6- phosphoglucose dehydrogenase in their bodies), and some people get up every day to have hemoglobinuria, which can be paroxysmal and sleeping hemoglobinuria. The main reason is that after a large number of red blood cells in blood vessels are destroyed, the hemoglobin content in plasma exceeds a certain amount.

Lead poisoning patients often see purple urine, which produces a lot of purple due to the disorder of hemoglobin synthesis. The color of purple urine is as easy to recognize as wine.

Second, white urine

Leuuria is mostly caused by urinary system infection caused by Escherichia coli, such as pyelonephritis, cystitis, renal abscess, urethritis and so on. White urine can also be seen in patients with filariasis.

Third, yellow urine.

The urine is dark yellow, yellowish brown and has a certain consistency. This is a large amount of bilirubin mixed in urine, which is common in patients with hepatobiliary diseases. Yellow brown urine should be distinguished from bilirubin urine or urine bile urine.

Bilirubin urine is often caused by inflammation, tumor or stone blockage in the biliary tract inside and outside the liver, which leads to sodium bilirubin entering the blood. When the sodium bilirubin in the blood exceeds a certain amount, bilirubinuria will occur.

Urinary cholangitis is often caused by liver damage, which leads to an increase in urinary cholangitis absorbed by the intestine. When urine enters, urinary cholangitis will occur. Or patients with hemolytic anemia, because a large number of red blood cells are destroyed, a large number of urinary bile components are absorbed through the intestinal wall and enter the portal vein circulation. Because the liver can't convert excessive urinary bile elements into bilirubin, urinary bile elements appear.

Fourth, black urine

Also known as dark brown urine, it often occurs in patients with acute intravascular hemolysis, such as patients with falciparum malaria. Medically called black urine fever, it is one of the most serious complications of malignant diseases. It can also be seen in people who come to the Soviet Union by mistake. Because phenol is partially oxidized into hydroquinone and catechin in human body, it will be discharged from urine, and urine will become black urine after standing for a period of time. In patients with melanoma, the melanin in the blood is reduced to melanin by the liver because of the increased melanin production in the body, and the melanin discharged from the urine becomes melanin after oxidation, and the urine turns black after standing for a period of time.

Five, blue urine

When methylene blue or triamcinolone acetonide needs to be injected for diagnosis or treatment, cyanosis may appear, but it can return to normal after stopping the drug.

In addition, when distinguishing urine color, we should pay attention to the influence of many factors on urine.

First, weather factors: for example, how long urine is when it is cold, and the yellow color can be deepened when it is hot, which is related to sweating and drinking water. For another example, when it is cold, children tend to urinate like rice soup. Urine will precipitate after a while and become clear after heating. This is physiological salinuria. As long as you drink more boiled water, the urine color will be normal.

Second, dietary factors: urine can also change with diet, such as eating acidic diet, urine color is dark; If the diet is alkaline, the urine color is lighter. Sometimes a few tablets of riboflavin are taken orally, and the urine color will be dark yellow. Changes in urine color like this are extremely short-lived and will soon recover on their own.

Third, drug factors: Some people have red or tan urine after taking drugs (such as furazolidone, enteritis spirit, vitamin B2, etc.). ) or use phenol red reagent and eat some food with pigment. Although the urine color is abnormal, they don't need to see a doctor.
