The kidneys have a very strong compensatory ability. When kidney function is slightly impaired, they can generally still handle the basic physiological functions of the human body through compensation, so patients may feel that everything is normal. Despite the fact that the occurrence and development of uremia is a long and gradually worsening process, which can sometimes be very severe, it is still possible to detect early signs of uremia if one actively seeks them out early on. Early indications of uremia can be identified in time by going to the hospital for urine and blood tests. The early signs of uremia often manifest as general fatigue, which is the symptom most easily overlooked. Other symptoms of early uremia include edema, especially noticeable swelling of the eyelids and facial area after waking up in the morning. If it develops into systemic or persistent edema, the condition is already very serious. Additionally, early-stage uremia patients may also experience an increase in the frequency of nocturnal urination and more foam in the urine, as well as increased blood pressure, and even dizziness, headaches, and a lack of appetite. These are all early signs of uremia.
