Ageing is associated with a physiological deterioration of kidney function, however, in patients with additional diseases such as diabetes, hypertension and obesity, there is often stronger severity of kidney damage. It has been estimated that the prevalence of chronic kidney disease (CKD) in the older population is several times higher than in the general population. It is considered that in addition to the mentioned above comorbid the socio-economic factors also increases prevalence of CKD.
