However, sometimes red and yellow urine is not only a small problem, it also indicates physical diseases. If you don't pay attention to it for a long time, it may endanger your health. Today, Xiaobian takes you to understand red and yellow urine. What is an exception?

What is the reason why urine turns yellow?

Mainly divided into physiological and pathological reasons

Physiological reasons:

(1) In normal urine, the color is light yellow. Because urine contains urochrome. If the color of urine turns yellow, it is related to the amount of water and eating habits. Generally, people who drink less water will have less urine and more urine pigment, and the color of urine will turn yellow. On the contrary, the color of urine will be colorless. Similarly, if you like to eat acidic and pigmented substances, your urine will become darker, and if you like to eat alkaline substances, your urine will become lighter.

(2) In terms of smell, the urine that has just been untied normally has the smell of grass. After a long time of storage, the urea decomposes to produce ammonia odor. After eating garlic, onions and medicine, the urine produces a special smell, which can usually disappear by itself. The above urination phenomenon is very short and physiological. Don't worry too much.

Pathological reasons

(1) Chronic prostatitis also turns yellow in urine and lasts for a long time. This may lead to chronic prostatitis

(2) Urinary yellow caused by urinary tract infection, accompanied by symptoms such as urethral pain, is easy to cause urethral infection.

(3) Urine is dark yellow, similar to brown, which may cause hepatobiliary lesions, and hepatitis patients are also dark yellow.

(4) Urine yellow and urethritis caused by urethritis can change the color of urine. Yellowing urine may also be caused by urethritis.

The color of urethra should also be noted:

1. The urethra turns red: the urine has blood red or fresh flesh color, and the urine may be mixed with blood, so it turns red, commonly known as hematuria. The inducement of hematuria may be problems in the urinary system, such as urinary system stones, serious and glomerular symptoms.

2. The urine is milky white: the urine is milky white. Why do you have milky white symptoms? The milky urine contains lymph and a large number of fat particles. Commonly known as chyluria. It often occurs in obese people.

3. The urine is brown. If the urine is dark yellow or black tea, it can promote acute hepatitis, cholecystitis and other liver and biliary system problems.
