[이데일리 이순용 기자] Urine is the result of metabolizing various substances in the body and then excreting them. Urine is produced as waste products are filtered out by the kidneys, stored in the bladder, and excreted through the urethra. A healthy adult’s daily urine volume is 1-1.5 L. Usually 350mL of urine is excreted at a time. The number of urination varies depending on the season and temperature, but it is usually 5 to 6 times a day for adults.
More than 90% of urine is water. In addition, it is composed of components such as amino acids, uric acid, urea, and inorganic salts. It is similar in composition to sweat, which is made in a similar process. The only difference is that sweat contains 99% of water and urine contains urea.
Shin Seok-joon, professor of nephrology at Incheon St. Mary’s Hospital, Catholic University of Korea, said, “We think of urine as simply a part of waste, but in fact, urine is an important health indicator that indirectly shows the condition of our body.” If you observe deeply, you can get information regarding various diseases that occur in our body.”
◇ Decreased urine volume and strong odor are signs of health problems
If your urine volume is reduced and it smells bad, it might be a sign that something is wrong with your body. First of all, the decrease in urine volume is an important problem that is directly harmful to the kidneys. Drinking enough fluids to prevent dehydration is important for kidney health. About one-fourth of the cardiac output goes to the kidneys, and if the amount of water going to the kidneys decreases for any reason, the amount of urine decreases. If you sweat a lot in the heat, if your heart function drops, or if you can’t send enough blood to the kidneys due to low blood pressure caused by shock, such as bleeding or infection, the amount of urine will decrease. Acute or chronic kidney failure may result in reduced urine output.
If the amount of urine per day is less than 500mL (polyuria), severe dehydration, obstruction of the urinary tract, and advanced chronic kidney disease can be suspected. discharged and accompanied by thirst) can be suspected.
Normal urine is odorless and slightly acidic. If your urine smells like ammonia, it might be due to dehydration or a urinary tract infection. The musty smell may be due to liver disease or metabolic disorders, and the sweet smell may be due to metabolic disorders such as diabetes. After eating parsley or asparagus, there may be a pungent odor.
Normal urine is foamy, but not in large amounts. A small amount of foam is not a big deal, but if the foam is large and does not dissipate, it is a sign that protein is leaking into the urine. Proteinuria means there is a problem with the kidneys and you should get a urine test right away. However, even healthy people may have foamy urine temporarily if they have eaten a lot of meat, exercised heavily, or have a high fever.
Professor Shin Seok-joon said, “Usually, less than 150 mg of protein is excreted in the urine a day, and if protein in the urine increases abnormally, abnormal kidney function can be suspected.” As much as there is, an inspection is absolutely necessary.”
The color of urine should also be observed carefully.
Normal urine is a clear tan color with a light beer color. Urine color is determined by the concentration and components of urine, and it is normal for it to be slightly yellow because bilirubin, a metabolite of red blood cells, is excreted in urine through the liver. If jaundice is severe due to abnormal liver function, the urine becomes dark yellow. Taking vitamins or nutritional supplements can also make your urine yellow. After running a marathon, marching, or climbing for a long time, you can see dark brown urine along with muscle pain. Sometimes, it can appear when myoglobin from the destruction of muscle cells is excreted.
Dark, cola-colored urine can occur when you have acute kidney disease, which results in too much red blood cells leaking out of your blood vessels. Macroscopically, red hematuria can come from urinary tract infections such as acute cystitis, and hematuria caused by bladder cancer or kidney cancer should be suspected in older men who smoke. Rarely, the color of urine may be blue or green. It may be caused by some genetic diseases, but usually it is caused by food coloring or medication, so it is good to consult a specialist. If you have red hematuria accompanied by intense pain in your side or lower abdomen, it might be a urinary stone. In addition, if it is difficult or frequent to urinate, if blood is mixed with urine and semen, or if you feel pain when urinating, you should check for prostate cancer.
Professor Seok-jun Shin said, “Once hematuria is diagnosed, it is necessary to check for traumatic urinary tract injury, kidney or ureteral stones, cystitis, bladder cancer, or kidney cancer.” It’s good to get it regarding once, and if you have a family history, you should get regular checkups from the age of 40,” he emphasized.
