The color of a person’s urine is constantly fluctuating depending on his state of health. Its color depends on the presence of pigments uroerethrin, urochrome, urorosein and other substances contained in it. What can white urine testify to?
With a greatly reduced content of various substances in it, the color of urine becomes very pale (whitish). It becomes almost colorless, which is very characteristic of a disease such as polyuria. Almost the same color is observed in urine in people with diabetes. Despite its relatively high specific gravity, urine has a very pale color. The proportion of it in absolutely healthy people throughout the day usually fluctuates in a rather large range, due to the periodic intake of various foods and the loss of fluid from the body, excreted with exhaled air and sweat. Normally, it equals from 1012 to 1025. It directly depends on the number of substances dissolved in the urine: creatinine, uric acid, urea, various salts. A significant decrease in its specific gravity (hypostenuria) to the level of 1005-1010 is characteristic of polyuria, a decrease in the concentration ability of the kidneys.
An increase in the specific gravity of urine (hyperstenuria) more than 1030 is characteristic of oliguria, glomerulonephritis, and patients with cardiovascular insufficiency. With polyuria, a very high beat is observed. the weight of urine in diabetes mellitus (its weight can reach the level of 1040-1050).
Milk-white urine is observed with pyuria, with the release of a significant amount of phosphates, with lipuria.
Turbid whitish urine is often caused by a disease such as phosphaturia. With this disease, salts most often do not go all the time, but periodically, and therefore they are not determined in all urine tests. If you suspect this disease, several tests are performed throughout the day. This ailment requires the consultation of a urologist, because only he can decide on the timeliness of therapy.
Phosphaturia is diagnosed when phosphates (magnesium phosphate) and calcium phosphate salts are detected in urine. If white urine, when heated and pouring acetic acid into it, becomes cloudy without bubbles, this may indicate phosphaturia. With this disease, white urine has a characteristic color of diluted milk. Phosphaturia is usually associated with an alkaline urine reaction and is most often diagnosed in women. The stones that form during this disease are grayish or white phosphates ; they have a loose structure. Phosphate stones are most often formed during hyperfunction of the parathyroid gland as a result of failure of phosphate reabsorption, the occurrence of urinary infection, and during the deposition of salts in the structure of the kidneys. Often this disease is accompanied by bilateral and coral nephrolithiasis.
The answer to the question of why urine is white can only be given by a specialist after conducting several urine tests and finding out the full clinical picture of the disease. The situation when the color change of urine has a long and regular character is especially noteworthy. White urine may be associated with the occurrence of other diseases and causes, such as chyluria, discharge of salts, secretion of lymph and fat. Very often, a color change in urine is observed when an inflammatory process occurs in the body. In this case, white urine is due to the presence of a significant amount of pus in it. Its color in the inflammatory process can range from white to gray. The appointment of the correct therapeutic treatment is usually done by a urologist after examining not only “morning urine”, but also that urine that has a white tint.
