Normal urine color: Normal people's urine color is light yellow, and its pigment mainly comes from uroflavin and a small amount of urobilin and urorubin, which are products of the body's metabolism. The color of urine is not always the same. It can change depending on the amount of water consumed, diet, or disease.
If you drink enough water, your urine will turn pale yellow; If you are a bit dehydrated, the urine color will deepen. The yellow color in urine mostly comes from aging blood cells. After undergoing a series of body metabolism, they will be decomposed, eventually arriving in the urethra as a pigmentation agent, and eventually being expelled from the body. The less water in the bladder, the darker the color of urine, so the color of morning urine is generally darker. If your urine appears red, orange, or even green, don't panic, as it's often due to the food you eat.
Bubbles in urine: a man's "anterior gland" crisis.
If you find a layer of tiny foam floating on the surface of urine for a long time, it may be an early symptom of nephritis or a hint that men have prostatitis. This "small bubble" is caused by a high level of protein in the urine. The earliest change in nephritis is the presence of protein in the urine. If not actively treated, it is extremely prone to kidney dysfunction and other problems.
In addition, if a man suffers from prostatitis, he may carry prostate fluid in his urine, which may result in oil droplets on the surface of his urine, presenting a "bubble urine" state with many "small bubbles". Normal condition: If the foam is large or different in size, and the duration is short, it belongs to the normal foam, so there is no need to be nervous.
Red urine yellow band: urinary tract infection.
A red color in urine is likely a symptom of urinary tract infection, such as urethritis, urinary system stones, and so on. Generally, there are problems with frequent urination, urgency, and pain in urination along with hematuria. It is recommended to go to the urology department of the hospital for an examination to avoid missing the best opportunity for treatment. Normal condition: Eating vegetables and fruits with natural pigments such as carrots can also make your urine appear red. However, this phenomenon is only temporary. Drinking a few more cups of boiling water will slowly restore it.
Yellow urine is like strong tea: pay more attention to liver problems.
If urine turns yellow like strong tea for a long time, it often indicates liver problems. If the urine is yellow for a long time, it is important to be careful if there are other symptoms in the body, such as jaundice, fatigue, upper abdominal discomfort, and pain. You should go to the hospital for relevant examinations in a timely manner. Normal condition: If you only have yellow urine once or twice, the time is short, and there are no other discomfort, there is no need to worry. Changes in urine color are related to human sweating, water consumption, and diet. If you sweat more and drink less, the color of urine will also deepen;
Milk white urine: Diseases of the urinary tract.
Also known as chyluria, the most common form of chyluria is caused by filariasis, especially after drinking milk or a high fat diet. However, if milky white urine is accompanied by abnormal urination, fever, and low back pain, it should be suspected of being a serious urinary tract infection, such as pyelonephritis, cystitis, urethritis, or renal tuberculosis, causing the urine to appear milky white.
Too little urine: renal failure.
Due to differences in individual dietary habits, the amount and frequency of urination vary, but in general, people's average urine volume per day is around 6 cups (1500 milliliters), and the number of urinations per day is between 4-8. Of course, if you're a big drinker of water or beverages, there's more to your urine output than that; Or for those who suffer from thirst, it may be difficult for their bodies to produce 6 cups of excretion. If you drink a lot of water and still have very little urine, you can develop oliguria, which is related to renal failure.
