It is the most fearful that at the initial stage of nephrosis, a patient generally does not have obvious symptoms; but when there is discovery of obvious symptom, the kidney has already been damaged, losing half or more of its function. Therefore we should take prevention carefully by conducting health examination and body checks regularly. Some common and general nephrosis symptoms include: muddy urine, urine with blood, dark brown in colour, with bubble, not smooth, painful during urination; frequent urination; too much or too little in terms of amount; face and feet edema; waist side ache; high blood pressure; poor appetite and anaemia.
