So, what are the symptoms of chronic renal failure? Renal failure is a pathological state of partial or total loss of renal function caused by the development of various chronic kidney diseases to the late stage. Renal failure can be divided into acute renal failure and chronic renal failure. Acute renal failure progresses rapidly, usually due to insufficient blood supply to the kidneys (e.g., trauma or burns), impaired function of the kidneys due to some kind of obstruction, or injury by toxins, which causes the development of acute renal failure. Chronic renal failure is mainly caused by long-term renal disease. With time and the progress of the disease, the function of the kidneys gradually decreases, resulting in the occurrence of renal failure. Symptoms of chronic renal failure: 1. Anemia: Due to the damage of kidney function, the human body can not produce enough hormones needed to make red blood cells, thus resulting in anemia. People with anemia often feel cold and tired. 2.Oedema: some patients will have edema. Decreased urine output and frequent urination (especially at night). Edema of the hands, feet and ankles. Other symptoms include shortness of breath and swelling around the eyes. 3. Discomfort: Due to the accumulation of toxins and waste products in the body, patients may feel unwell. Symptoms include nausea, vomiting, poor night sleep, lack of appetite, scratching and fatigue. 4. Other symptoms: hematuria (tea-colored or blood-red), high blood pressure, foam in urine, diarrhea, extreme thirst, disturbed sleep, or drowsiness, decreased libido. Chronic renal failure is very harmful to the body if you have such a disease. Therefore, if you find out that you have chronic renal failure, the thing to do is to be active treatment. Only through active treatment can you recover as soon as possible and reduce the harm caused by the disease.
