  • Diabetes – Prolonged diabetes has become a major cause of CKD.  The high blood sugar levels damage the blood vessels of kidneys. 
  • High blood pressure- High blood pressure is the second major reason for CKD. High blood pressure also damages the blood vessels of kidneys by putting high pressures on the vessels. Almost 1 in 5 adults with high blood pressure suffers from CKD. 
  • Heart disease – People with heart disease have a higher risk of suffering Kidney damage and vice versa.
  • Genetic factors – If your family member suffers from CKD, then likely you also have chances to get affected by the same.
