Renal failure may usually present with nausea and vomiting, loss of appetite, headache and dizziness, high blood pressure, anemia, edema, and decreased urination. Treatment needs to be based on the primary cause. Dialysis is needed if necessary. 1. Symptoms: With the development of renal failure, the body’s metabolic waste and water can not be discharged normally, which may cause metabolic acidosis, stimulate the gastrointestinal mucosal edema, vomiting, loss of appetite, headache and dizziness, and even coma and other symptoms. It may also cause the patient to urinate less, etc. 2. Treatment: If chronic renal failure is caused by hypertension, diabetes mellitus and other diseases, the original disease can be controlled by actively lowering blood pressure and sugar, and the symptoms of renal failure will be relieved. When renal failure progresses to uremia stage, dialysis may be needed to expel metabolic wastes and water from the body, thus relieving the symptoms. Patients with renal failure are advised to go to regular hospitals for timely consultation and standardized treatment under the guidance of doctors.
