Urine color and health status

The color of urine is closely related to human health. This can be seen from the fact that urine tests are included in the examination items for many diseases in major hospitals today. Of course, without conducting a urine test, if the color of a person's urine changes, the patient can also judge what problems exist in his or her body based on the color of the urine. Below we will introduce to you what the different colors of urine mean!

Brown urine

It may be bilirubinuria or urobilinuria. Bilirubinuria is often caused by intrahepatic or extrahepatic bile duct inflammation, tumors or stone blockage, which causes sodium bilirubin to enter the blood. When the amount of sodium bilirubin in the blood exceeds a certain amount, bilirubinuria occurs. Urobilinogenuria is often caused by liver damage, which leads to increased intestinal absorption of urobilinogen, which enters the urine, resulting in urobilinogenuria. Sometimes, in patients with hemolytic anemia, after a large number of red blood cells are destroyed, a large amount of urobilinogen is absorbed through the intestinal wall into the portal vein circulation. Because the liver cannot convert the excess urobilinogen into bilirubin, urobilinuria occurs.

Brown urine

Patients with severe burns, hemolytic anemia, wrong blood transfusion, acute nephritis, acute icteric hepatitis, or kidney compression may excrete urine that is the color of soy sauce. Some people excrete brown urine and experience dizziness, nausea, or yellow eyes after eating broad beans. They are medically called favism patients.

Milky urine

The most common is chyluria caused by filariasis, which is significantly aggravated especially after drinking milk or a high-fat diet. However, if milky urine is accompanied by abnormal urination, fever, and lower back pain, it should be suspected that it is a serious urinary tract infection, such as pyelonephritis, cystitis, urethritis or renal tuberculosis, which makes the urine milky white.

White mucous urine

Since the male urethra is the common exit channel for semen and urine, it is normal for adult men to occasionally discharge white mucus urine from the urethra and there is no need to worry too much. However, if white mucous urine is frequently discharged, it may be a symptom of prostatitis, non-gonococcal urethritis or gonorrhea. You should seek medical treatment as soon as possible, otherwise it will be transmitted to your spouse and cause inflammation of the reproductive organs.

Dark urine

Seen in people who accidentally ingest Lysol and suffer phenol poisoning. Because phenol is partially oxidized into hydroquinone and catechins in the human body and excreted through urine, the urine will turn into black urine after being left standing for a while. For example, patients with melanoma have increased melanin production in their bodies, causing the melanin in the blood to be reduced to melanosomes by the liver. The melanosomes excreted from the urine are oxidized to become melanin. After standing for a while, the urine turns black.
