Why is urine brown?

Light yellow urine is a normal state, but there are also special circumstances. For example, we will find that when we have a cold or a fever, we will find that the urine we excrete will be very hot and the color will be darker than usual. This will continue until the cold is gone. In addition, our urine may also appear brown, but this situation does not occur often. Why does brown urine appear?

1. The color of urine is often affected by food and medicine. For example, when taking vitamin B, rifampicin and other drugs, the color of urine will become darker. It will naturally improve after stopping the medication, so there is no need to worry. However, if the color of urine is very dark, does not become lighter after drinking water, or even the color is like strong tea, you should pay attention. If your urine is yellow for a long time, you feel tired and have loss of appetite, etc., you should consider whether you have any disease in your liver, kidney or urinary and reproductive system, and you need to go to the hospital for examination in time.

2. For patients with common fever or vomiting and diarrhea symptoms, the urine will be concentrated and reduced because water is excreted with sweat or feces, but the urine pigment will not change, so the color of the urine appears very yellow.

3. If the urine is yellow like strong tea, it is not due to the above reasons, but because of liver or gallbladder disease. It turns out that there are usually two ways for bile to be discharged: one from the urine and the other from the intestines. When the liver or gallbladder is diseased, the bile's path to the intestines is cut off and it can only be excreted in the urine. The urine also becomes dark yellow due to the increased bile content. In the early stages of hepatitis, before jaundice appears, we often see that the color of urine is like strong tea, which is often a sign of hepatitis.

4. Insufficient kidney qi and kidney deficiency can also cause yellow urine. Patients with common fever or vomiting and diarrhea symptoms will have their urine concentrated and reduced because water is excreted with sweat or feces, but the urine pigment does not change, so the color of the urine appears very yellow.

If you want to have a healthy body, you must always understand your physical condition. You need to understand it not only from your urine, but also from other aspects. In order to better ensure our physical health, we can participate in more physical exercises in our daily life, so that we can better enhance our physical fitness and prevent our bodies from suffering from the damage caused by diseases.

5. Know all kinds of diseases by looking at the color of urine

Normal urine is light yellow. Too light or almost colorless urine is caused by drinking too much water, which can be seen in diabetes insipidus and diabetes. Yellow urine can be caused by fever, drinking too little water, or excessive vomiting and diarrhea that lead to dehydration of the body.

Yellow urine can also be caused by taking drugs such as riboflavin and AstraZeneca. It is not surprising that urine turns yellow if you take carrots, carrots, or drink or eat foods containing yellow dyes.

The yellowish brown, yellowish green to brownish green color of urine may be caused by rhubarb, senna leaves, and cascara in acidic urine, but it is more often caused by increased urinary bilirubin and urobilinogen caused by hepatocellular, obstructive or hemolytic jaundice.

Brown or brown-black urine can be seen in acidic urine due to urinary tract bleeding. In addition, phenol poisoning and levodopa, nitric acid, lysol, formic acid, etc. can also cause the urine to be brown-black.
