Master these key points and easily grasp the kidney's distress signal

1. Changes in urine volume

The average daily urine output of an average person is 1000 to 2000 ml, with an average of 1500 ml. Whether the urine output increases or decreases, it may be a manifestation of kidney disease. In particular, the urine output of an average person is less at night. If you find that you need to get up many times at night and do not drink much water before going to bed, you need to be more alert to kidney disease.

2. Changes in urine characteristics

Normal urine is transparent and light yellow. If you drink less water or urinate for the first time in the morning, the color will be slightly darker. If the urine is red, dark tea color or even soy sauce color, or if there is a lot of foam in the urine that does not dissipate for a long time, this indicates that there may be hematuria or proteinuria, and you need to go to the nephrology department for further examination. Visible hematuria and microscopic hematuria found in urine examination are also important signs of urinary system diseases.

3. Edema

The kidneys are the organs that metabolize water in the human body. When kidney function declines, water will accumulate. If you find puffy eyelids when you wake up in the morning, or edema in your feet and lower limbs, or swollen fingers after sitting or standing for a long time, you need to pay attention to kidney problems.

4. Gastrointestinal symptoms such as nausea and vomiting

When kidney disease develops to the end stage, it will affect gastrointestinal function, causing symptoms such as nausea, vomiting, and loss of appetite. Therefore, when these symptoms appear, in addition to seeing a gastroenterologist, you should also pay attention to excluding the possibility of kidney disease.

5. Itchy skin

For patients with end-stage renal disease, urea in the body cannot be excreted through urine and will be excreted through the skin, thereby irritating the skin. In addition, toxins accumulated in the body can lead to peripheral neuropathy and also cause skin itching.
