Symptoms of uremia mainly include nausea, vomiting, fatigue, edema, etc. Some patients may also develop heart failure or pulmonary edema, resulting in chest tightness and shortness of breath. Patients with uremia have an almost complete loss of kidney excretory capacity and may suffer from decreased appetite, nausea, and vomiting due to the accumulation of metabolic wastes affecting the digestive tract. Almost all of these patients have anemia, and the degree of anemia is parallel to the degree of renal failure, because anemia causes weakness, pallor, etc.. Some patients may have edema of the body due to inadequate water excretion, which is especially noticeable on the face and both lower extremities. If water is further accumulated, heart failure and pulmonary edema can occur, which is manifested as dyspnea, chest tightness, coughing, etc., and there is a great danger to life. There are many other possible symptoms, such as headache, dizziness, panic, itchy skin and so on. None of these symptoms are specific, and you can’t completely rely on the symptoms to determine the disease. It is recommended that patients with decreased kidney function should consult the hospital in time, clarify the cause under the guidance of doctors and take active treatment to avoid the progression of the disease.
