Red urine : Red urine is very common. Hematuria is one of the most common causes. The depth of the color is related to the amount of red blood cells in the urine. When the amount of red blood cells is high, it will be the color of meat washing water. Injury and bleeding in any part of the urinary tract can cause hematuria, such as acute nephritis, urinary tract stones, tuberculosis, tumors, congenital malformations of the urinary system or exercise-induced hematuria. In addition, systemic diseases such as blood diseases and certain infectious diseases can also often cause hematuria. When muscles are severely squeezed, myoglobin enters the blood and is excreted through the kidneys, and the urine may also be dark red. Brown urine (hemoglobinuria) : A large number of red blood cells are destroyed in the blood vessels, and the urine is dark brown or soy sauce-like. For example, favism, hemolytic transfusion reaction due to blood type incompatibility, etc. Brown urine (bilirubinuria) : The urine is dark yellow or brown, and the foam is also yellow after shaking the urine. It is mostly seen in patients with jaundice, such as acute icteric hepatitis or biliary obstruction. Milky urine : Chylous urine contains lymph and is milky white, which is often seen in filariasis. Purulent urine caused by severe urinary tract purulent infection contains pus in the urine, which is white and turbid and contains pus filaments. Blue-green urine : When taking large amounts of anti-inflammatory drugs or when Pseudomonas aeruginosa grows in the urine, green urine will be discharged. If blue urine appears, it is mostly related to taking related drugs. Although urine color can tell us about some diseases, we should not panic when we see color changes, because pigments and other compounds in certain foods and medicines can change urine color. The most common is bright yellow urine when eating a lot of carrots; taking the Chinese medicine rhubarb can make urine dark yellow like strong tea; and eating a lot of dragon fruit will turn urine red. Careful people may observe their own urine. Sometimes it is clear, sometimes it is yellow, and sometimes it is white and turbid. I hope that through today's popular science, I can help you to uncover the little secrets in urine. |
