What causes yellow urine?

Yellow urine is quite common in our daily life, and there are many reasons for it, including both physiological and disease-related reasons. For example, drinking too little water and food reasons may cause the urine to turn yellow. Of course, we must be alert to some diseases that may cause yellow urine, such as liver damage, bilirubin in the gallbladder entering the blood circulation, etc. Let’s take a look at this aspect below.

What causes yellow urine?

1. Yellow urine due to physiological factors. Yellow morning urine occurs when you first urinate in the morning. There is no need to 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: In clinical examinations of liver and kidney diseases , 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.

Why is my urine yellow in the morning?

Yellow urine. If it is just yellow without any other discomfort, this is mostly a normal condition of the human body. The normal color of human urine is originally light yellow. Especially in the morning, every time you urinate, the chance of yellowing is very high. Some people will also have yellow urine when eating vitamin B, or foods such as carrots, or other medicines such as Sulfate. It will disappear after stopping, so you don't need to pay attention to it. If the urine is very yellow, even like strong tea, even if there are no other obvious symptoms, you should consider liver and gallbladder disease and see a doctor immediately. If the urine is yellow and accompanied by urethral fever, this is a mild urethritis, which is commonly known as getting angry, especially when you urinate for the first time in the morning, there will be no feeling of fever when you urinate the second time. This is mostly due to not getting a good rest the day before, or eating foods that are easy to get angry, such as chili peppers, alcohol, etc. This does not need to be treated, everyone will experience such situations countless times in their lives.
