The usual, normal color of urine is light straw, less often - transparent, "watery". There may be fluctuations within this norm. For example, a straw color with a hint of brown or orange is also a normal color. However, for example, if your urine has taken an unnatural, pathological color - for example, green, pink or dark - this is already abnormal. Pink urine can have both completely harmless reasons and may be the result of a pathological process. Now more about this.
Usually red urine is a cause for concern. True, they are not always justified, since urine may be red, not only because of the blood content, but also for other reasons. For example, if you took a drug such as phenolphthalein, then do not be surprised at the radical change in the color of the secretions. The same result can be obtained if you ate foods containing beets, especially in large quantities. Rhubarb or blackberry also gives coloring. It often happens that “blood in the urine” appears some time after consuming these products. The color depends on the composition of the drinks you drink, the food you eat and the drugs you take. However, how to determine whether the color of urine is caused by your diet, drink, taken medications, or does this phenomenon have another, more serious reason?
If your urine is pink, anamnesis and research data under a microscope help to make a diagnosis. If blood was detected in it, then you may be suffering from hematuria or hemoglobinuria, or another disease that causes such a symptom. Also the cause may be kidney disease and some others.
Clinical analysis of urine compares odor, weight, color, density, acidity, composition, search for the presence of various organic substances and other data. Additionally, biochemical analysis methods can be used. Sometimes it happens so, in the urine of an unusual color, no causes of a color change have been identified. For example, the urine is pink in color, and it contains neither red blood cells, nor substances that could become dyes - the reason was not found by conventional analysis methods. In this case, the submitted sample should be sent to Nechiporenko for analysis.
Red is the result of a blood admixture in most cases. If urine of red color looks like bloody, "meat" slops, then this is a sign of glomerulonephritis, or rather, exacerbation of its chronic form. Glomerulonephritis is a kidney disease that cannot be started, otherwise otherwise a chain of complications can ultimately lead to a uremic coma.
Red urine is often the cause of blood cells and red blood cells (hematuria). The causes of hematuria are infections that affect the urinary tract, a wide variety of diseases of the kidneys or bladder. If your urine is pink in color and you experience severe pain during urination, or burning in intimate places, this is a sign of an infectious disease that affects the genitourinary system. In this case, it's time to contact the urologist. Another possible reason that your urine is red is intoxication. For example, ingestion of porphyrins gives it a red (or pink) color.
Dark urine in a child is, in any case, a cause for serious concern on the part of parents. After all, this is a sign that his body has undergone toxic damage. It is much less common that dark urine in a child has completely harmless reasons. Some of the substances that can darken are certain types of salts and bilirubins. Dark urine in a child can be an external consequence of the defeat of his body by toxins or the development of another, no less serious pathology. The analysis should identify the toxic substance that affects the child, or another cause. Based on the causes of intoxication (or another ailment), appropriate treatment should be prescribed. In addition to being hit by toxic substances, another possible reason that a child’s dark urine is melanoma or hemolytic anemia.
