Is it normal for urine to be like clear water?

Generally speaking, the color of urine is light yellow and the odor is relatively small. This is normal urine. If the urine appears to be like clear water, don't worry too much. It is probably caused by drinking too much water. In addition, the weather is relatively cold. If you catch a cold, it may cause frequent urination. At this time, the urine may be like clear water. At this time, you should pay attention to keeping warm, drink water in moderation, and not drink too much.

How much urine does a person produce every day?

Medical research results show that the normal daily urine output of a normal person is 1000 to 2000 ml, with an average of about 1500 ml. Because a normal person has 35 to 50 grams of metabolic products and salt substances that need to be excreted from the body through the kidneys in the form of urine every day, and the minimum amount of water required to dissolve these solid substances is about 500 ml, so everyone must excrete at least 500 ml of urine every day.

Therefore, according to medical regulations, when a person's urine volume exceeds 2500 ml throughout the day (24 hours), it is considered polyuria; if the urine volume throughout the day is less than 500 ml, it is considered oliguria; even more, if the urine volume is less than 100 ml, it is considered anuria.

Can urine color indicate medical problems?

1. Yellowish-brown urine: It may be caused by 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.

2. Brown urine: Patients with severe burns, hemolytic anemia, wrong blood transfusion, acute nephritis, acute icteric hepatitis, squeezed kidney, etc. may excrete urine 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.

3. Milky urine: The most common type of urine 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.

4. White mucus urine: Since the male urethra is the common exit channel for semen and urine, it is normal for adult males to occasionally discharge white mucus urine from the urethra. 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.

5. Black urine: seen in people who accidentally take 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.
