When wiping, the urine is brown

The urine of a normal person should be light yellow or pale yellow. If the body is healthy enough, the urine will be very clear, almost like water without any changes. However, abnormal urine will be some coffee color or turbid. This symptom may be caused by too much hemoglobin in the urine. It is also possible that it is related to kidney inflammation, bladder disease and urinary tract infection.

Normal fresh urine is light yellow in color because it contains a yellow pigment called urochrome.

However, the color of urine can also be dark or light depending on the amount of water you drink. If you drink more water and urinate more, the proportion of urochrome in the urine will be smaller, and the color will be lighter; if you drink less water, the proportion of urochrome in the urine will be larger, and the color will appear yellow. If urine is left for some time, its color will become darker. This is because some of the urochrome in the urine has been oxidized into urochrome. The waste produced by the human body and the urine pigments excreted every day are generally relatively constant, so the color of urine will not change much. 96%-99% of urine is water, and most of the rest is waste, such as uric acid, creatinine, etc. The normal daily urine volume of a person is 1000-2000 ml, among which men produce 1500-2000 ml per day. 1000-1500 ml for women. The urine is light yellow in color, transparent, and has no precipitation or turbidity. Freshly excreted urine has a special grassy aroma, but after being left for a long time, it develops an ammonia smell due to decomposition.

Most abnormalities in the human body can cause changes in urine .

(1) Abnormal urine color

●Colorless urine may be a sign of diabetes, chronic interstitial nephritis, or diabetes insipidus. If it is not caused by drinking too much water, you should be careful to identify it.

●White urine White urine is common in purulent urine, chyluria and salt urine.

Purulent urine is caused by severe purulent urinary tract infection, and the urine is milky white. Purulent urine is common in pyelonephritis, cystitis, renal abscess, urethritis, or severe renal tuberculosis.

Chylous urine is one of the main symptoms of filariasis, and the urine is white like milk. Because the chyle (liquid after fat saponification) absorbed by the intestine cannot be drained into the blood circulation from the normal lymphatic vessels, it can only flow back into the lymphatic vessels of the urinary system, causing increased pressure in the lymphatic vessels in the urinary system, varicose veins and rupture, allowing the chyle to overflow into the urine, resulting in chyluria. Chylous urine is usually paroxysmal. When there are red blood cells in chyluria, it is called chylous hematuria. Microfilaria (i.e. young filaria) can sometimes be found in the blood and urine of patients with chylous hematuria.

● Salty urine is common in children in winter. The urine is rice-soup-like and usually contains a large amount of phosphate or hydrochloric acid. It is easy to precipitate after being left. If the urine is placed in a bottle and heated, it will immediately become clear. Salt urine is a normal physiological phenomenon. It can be cured without medication, the key is to drink more boiled water. .

●Yellow urine refers to urine that is yellow or dark yellow. The reasons are :

When eating carrots, taking riboflavin, furazolidone, mefenamic acid, rhubarb and other Chinese and Western medicines, the urine may turn yellow. Once you stop taking the medicine, the yellow color will disappear immediately, so there is no need to worry.
