Yellow urine does not necessarily mean that you have a fever. It is just a change in the color of urine. There are many reasons for this condition, and they should be treated differently.

Physiological yellowing of urine is often related to the amount of water consumed, the amount of exercise, and the intake of certain foods or medications, but these are temporary and can be changed by adjusting diet or lifestyle habits. If the urine is yellow for a long time and cannot be changed through the above adjustments and it progressively darkens, then you should seek medical attention and receive timely diagnosis and treatment.

Why is urine yellow?

The color of urine mainly comes from urobilin, which comes from conjugated bilirubin in the blood. Bilirubin is produced in the liver and then discharged into the intestine with bile. Under the action of intestinal flora, it becomes urobilinogen . Most of the urobilinogen is excreted through feces, called sterobilin . A small part is reabsorbed back into the blood and filtered through the kidneys, called urobilin and excreted from the urine. Therefore, urine is generally light yellow.

If you drink less water, sweat more, and lose water, your urine will become more concentrated and more yellow.

If the liver, bile duct, or pancreas is diseased or hemolysis occurs, affecting the production and metabolism of bilirubin or urobilinogen, urobilinogen, the body will show symptoms of jaundice and the color of the urine may turn yellow.

What health risks do urine of different colors reflect?

1

Colorless urine

Colorless urine may be caused by drinking too much water, or it may be a sign of diabetes or diabetes insipidus. If it is not caused by drinking too much water, it is recommended to go to the hospital for further examination and identification.

2

White urine

White urine is common in purulent urine, chyluria and salt urine. Purulent urine is often caused by severe urinary tract purulent infection, while chyluria is one of the main symptoms of filariasis. Urine is white like milk. If it is combined with red blood cells, it is called chylous hematuria.

3

Dark yellow urine

If your urine is yellow like strong tea, it may be due to a lesion in the liver or gallbladder, and is often a sign of hepatitis.

In addition, yellow turbid pyuria or urethral pus discharge is a manifestation of suppuration of the urinary organs and requires timely medical treatment.

4

Blue urine

It can be seen in cholera, typhus, primary hypercalcemia, and vitamin D poisoning. However, this color of urine is mostly related to medication, not caused by disease.

Blue urine may occur after taking the diuretic triamterene, injecting methylene blue, or taking methylene blue, indigo carmine, creosote, or salicylic acid. It will disappear after stopping the medication. This blue urine caused by medication is a normal phenomenon and there is no need to worry.

5

Green urine

Dark green urine is common when Pseudomonas aeruginosa grows in the urine, or when bilirubinuria is left for too long and oxidized into biliverdin. Light green urine is common after taking large amounts of anti-inflammatory drugs.

6

Dark urine

Black urine is relatively rare and often occurs in patients with acute intravascular hemolysis, such as patients with malignant malaria. It is medically known as "black urine fever" and is one of the most serious complications of malignant malaria. A small number of patients may also have black urine after taking levodopa, cresol, phenylhydrazine, etc., which will disappear after stopping the medication.

7

Red urine

When urine turns red, it usually means there are red blood cells in the urine, which is medically known as "hematuria".

Hematuria is one of the most common symptoms of urinary system diseases. 98% of hematuria is caused by urinary system diseases, and the rest is caused by systemic diseases or lesions of organs adjacent to the urinary system. Disease causes include inflammation, urinary stones, urinary tumors, abnormal coagulation function, vascular malformations, trauma, nephritis, prostatic hyperplasia, etc.

What is the normal urination pattern for adults?

A normal adult urinates 6-8 times a day, including 4-6 times or less during the day and 0-2 times at night.

The total amount of urine excreted per day is 1000-1500 ml. The maximum bladder capacity of a normal man is 450-550 ml, and the maximum bladder capacity of a normal woman is 400-500 ml, but each urination is generally between 300-400 ml, and the urine color is light yellow or transparent.

The frequency of urination is affected by various factors, such as age [the bladder capacity of children is (age + 1) * 30ml], bladder size, the presence or absence of diseases (diabetes, urinary tract infection), medications (diuretics), fluid intake (water, beverages), and types of beverages (alcohol, coffee), etc., all of which can lead to increased urination.

If the amount of urine voided each time decreases, the total amount of urine voided does not change, and the frequency of urination increases, you need to consider whether a disease has occurred, such as overactive bladder, interstitial cystitis, neurogenic bladder, etc.

Overactive bladder refers to involuntary contractions of the bladder or increased sensitivity to the urge to urinate, and often requires behavioral training and drug treatment.

Interstitial cystitis is a disease caused by bladder mucosal lesions that lead to bladder contracture. In severe cases, it is accompanied by lower abdominal pain and discomfort. Timely medical treatment is required to achieve better treatment results.

The frequent urination and urgency caused by neurogenic bladder is due to bladder dysfunction caused by nervous system lesions (trauma, inflammation, etc.), and needs to be classified and treated according to the nerve damage.

in conclusion

The statement that "yellow urine means you are getting angry" is inaccurate, because yellow urine is only a change in the color of urine. Changes in various components in the urine will cause corresponding colors. Whether there is a specific pathological change needs to be judged by the combination of other physical discomfort symptoms.

If the color of urine changes, it is recommended that you drink more water to promote urination. If you are taking certain foods or medications, you can stop taking them. If the color of urine does not change, it is recommended to seek medical attention in time.
