What causes yellow urine?

Everyone must think that yellow urine is a very normal thing, but not everyone knows why urine is yellow. Don’t underestimate yellow urine. It may be a dangerous signal of many diseases and must be taken seriously. Yellow urine in women is closely related to many chronic diseases. Therefore, everyone must first understand the causes of yellow urine before effective symptomatic treatment.

Yellow urine mainly means that the color of urine excreted from the body is light yellow or yellowish brown. The main reason for yellow urine is physiological factors. For example, many people's morning urine is somewhat yellow, or some drugs cause the urine to turn yellow. In addition, there are several other factors that may cause yellow urine:

1. Yellow urine due to physiological factors

Yellow morning urine

If your first urine after getting up in the morning is yellow, don't worry. Because after a whole night of rest, the urine in the body will be concentrated, the waste content will be higher, and the color will be yellower. Especially when you drink less water, the color of your morning urine will be darker. This is normal and there is no need to worry.

Food causes

Eating vegetables and fruits with natural pigments, such as carrots, can also change the color of your urine. However, this phenomenon is only temporary. If you drink a few more cups of water, it will gradually return to normal.

2. Pathological yellow urine

Liver and kidney diseases

In clinical examinations, yellow urine is divided into two categories: one is bilirubinuria and the other is urobiligenuria.

Bilirubinuria refers to the condition in which bilirubin in the gallbladder enters the blood circulation. The cause is usually inflammation of the bile duct, which causes the bile duct to rupture, resulting in bile entering the blood.

Urobilinogenuria is caused by liver damage. Liver damage increases the intestinal absorption of urobilinogen, and when urobilinogen dissolves into urine, yellow urine appears. In addition, people with hemolytic anemia will have massive destruction of red blood cells, and urobilinogen will also be absorbed through the intestines, causing the liver to be unable to convert a large amount of urobilinogen into bilirubin, which will also cause urobilinogenuria.

Yellow urine after sex

Many women will have yellow urine after having sex, and the urine has an unpleasant odor. Sometimes it is caused by condoms, but most of the time this yellow urine is generally caused by reproductive system diseases, with inflammation being the most common.

3. Taking certain medications can also cause yellow urine

This type of drugs includes riboflavin, which can cause yellow urine, as well as furazolidone and mefenamic acid, which can also cause yellow urine. Other drugs that can cause yellow urine include rhubarb. The yellow urine will disappear after stopping the medication, so there is no need to worry about this type of yellow urine.

Through the above introduction, have you understood what yellow urine is? Yellow urine is not a normal phenomenon in many cases, so female friends should not take it lightly. If the urine is yellow for a long time, you should go to a regular hospital for a detailed examination to avoid delaying the development of the disease and missing the best time for treatment.
