What causes dark yellow urine?

The color of urine represents the health status of the human body. Under normal circumstances, urine is light yellow. However, due to people's bad eating habits, sleeping habits and other living habits, the health of the human body will decline. It is very common for the color of urine to become dark yellow. In the face of this situation, people need to actively understand the cause and then treat it. Here we will introduce what is going on with dark yellow urine.

Light yellow is the normal color of urine. Urine originates from the glomerulus of the kidneys, and enters the bladder through the renal pelvis and ureter through the action of the collecting system such as the renal tubules. Urine needs to pass through a gate to flow out of the bladder, which is the urethral sphincter. Male urine also needs to pass through the prostate section of the urethra before it can be discharged from the body. Any disease in any organ that the urine passes through will affect the color of the urine. The color of normal human urine is light yellow. Its pigment mainly comes from uroflavin and a small amount of urobilin and urohemoglobin, which are products of the body's metabolism. When you drink less water or sweat more, the urine volume decreases, the urine becomes concentrated, and the urine color turns dark yellow. When drinking a lot of water, the urine volume increases, the urine becomes dilute, and the urine color becomes lighter or even transparent.

Why is my urine a little yellow these two days? Urine is the scavenger in our body's circulation, and its main components are 95% water and 5% metabolites. Therefore, we can completely identify the health of our body by the color of urine. 1. Drinking too little water can cause the color of urine to be dark or light depending on the amount of water you drink. If you drink more water and urinate more, the proportion of urochrome in your urine will be smaller and the color will be lighter. If you drink less water, the proportion of urochrome in your urine will be higher, and the color will appear yellow. However, if it is accompanied by physical discomfort, or if there is no significant relief after drinking water, you need to pay attention. 2. People with urinary diseases such as cystitis or urinary tract infection may also have yellow urine, and the urine is also accompanied by a strong odor. Not only that, these patients also experience pain when urinating. 3. Drug abuse: The color of urine is often affected by drugs. The yellow urine may be caused by drugs. For example, after taking Chinese and Western medicine such as vitamin B, rifampicin, furazolidone, mefenamic acid, and rhubarb, the urine may turn yellow. Once you stop taking it, the color will disappear immediately, so there is no need to worry.
