Life cannot do without eating, drinking, defecating, and urinating. Urine is not only a way for the body to excrete waste, but also a ‘barometer’ of health conditions. Gynecologists introduce that urine is composed of various substances such as uric acid, urobilinogen, and uroerythrin. These components are all products of metabolism within the body, existing in a certain proportion. Therefore, under normal circumstances, urine will maintain a certain concentration, which is why the color of urine is relatively fixed. When the color of urine appears abnormal, people can observe certain diseases from their own urine. Therefore, to a certain extent, the color of urine is not only a ‘barometer’ of physical health, but also a ‘signal flare’ of diseases.

The ‘rainbow’ world in the urine

The color of urine is not constant, and it can change with water intake, diet, or diseases. If you drink enough water, your urine will be light yellow; if you are slightly dehydrated, the urine color will deepen. The yellow color in the urine comes from aged red blood cells, which are decomposed after a series of body metabolism and finally excreted as pigment precipitants through the urethra. The less water in the bladder, the darker the urine color, so the color of morning urine is generally deeper.

Let’s see what problems the color of urine shows

Gynecological experts introduce that the color of normal urine can vary in depth due to different water intake, sweating, and activity levels, generally from light yellow to deep amber. When the body’s metabolism is abnormal or a certain disease is present, the color of the urine will change abnormally.

I. Yellowish-brown urine:It is common in obstructive jaundice, liver cirrhosis, type A hepatitis, and poisoning by arsenic, chloroform, etc.

II. Red urine:

Urine that can be seen with the naked eye as red is called gross hematuria. The urine contains a large number of red blood cells. There are many causes of hematuria, common in inflammatory diseases of the urinary and reproductive systems, stones, and tumors, such as various types of nephritis, renal tuberculosis, acute cystitis, urethritis, and stones and malignant tumors in the aforementioned areas. Systemic diseases such as leukemia, scarlet fever, and congestive heart failure can also cause hematuria.

III. Hemoglobinuria:

It refers to the presence of free hemoglobin in the urine. Since there are no red blood cells or only a small amount of red blood cells in the urine, the urine is clear and wine-red in appearance. It is common in malaria, favism, incompatible blood transfusions, hemolytic anemia, paroxysmal hemoglobinuria, and abdominal bleeding.

IV. Dark red hematuria:

It is common in bilirubinuria, often associated with type A hepatitis.

V. Milky urine:

Also known as chyluria, this is caused by the inability to absorb chyle from the intestines, resulting in chyle reflux into the urine. The causes of chyluria include congenital factors, such as congenital abnormalities in the function of the lymphatic valve; and secondary factors, such as common filariasis and purulent infections of the urinary system.

Is yellowish urine a sign of gynecological disease?

The normal color of urine is generally light yellow, but many friends may have found that they often have urine that is yellow or amber in color, which is what we call yellowish urine. Gynecological experts explain that the cause of yellowish urine in women, in addition to the common situations caused by drinking less water or taking medication, may also be related to diseases.

For example, some women may experience a yellowish urine after sexual intercourse, and the urine has an unpleasant smell. This condition may sometimes be caused by the condom, but in most cases, this yellowish urine is generally caused by diseases of the reproductive system, with vaginitis and other inflammatory diseases being the most common. Therefore, if a woman finds that her urine is yellow, she had better be vigilant and check whether she has gynecological diseases or other problems.
