1. Decreased urination
In life, if you find yourself drinking the same amount of water in peacetime, your urination times are completely different from before. For example, you used to urinate 2-3 times when you drank 1ml of water, but now you only urinate once at most. Moreover, when urinating, it is obvious that the amount of urination has decreased a lot, so this may be a problem with the health of the kidney. If there is a decrease in urination, it is likely to be related to renal failure.
2, the body began to appear edema
The function of the kidney can help our body to metabolize excess water, but once there is a problem with the function of the kidney, the water cannot be metabolized well, which will lead to edema in the body. The most obvious manifestation is edema in the lower limbs, and edema will also appear in the eyelids. If these two parts of your body suddenly swell inexplicably, it may be that the kidney is reminding you that there is something wrong with it.
3. Poor appetite
Usually, your appetite is good, but for a while, you find that your appetite has become poor, and then you have no interest in eating anything. Many people think that it is likely that there is something wrong with the digestive system, which will lead to poor appetite. In fact, this is not the case. It is likely to be renal failure. When there is a problem with the kidney, it will affect digestion, so don't think that the poor appetite is a gastrointestinal matter, and pay more attention to the kidney problem.
4. When urinating, there is foam in the urine
When our kidney function fails, it is easy to have proteinuria. Proteinuria means that there are many bubbles in urine, and this bubble will not recede for a long time. If such a problem occurs when you urinate, you must pay attention to it. This shows that your kidney has been seriously damaged, so you must go to the hospital for a detailed examination, so that it is possible to control your condition.
