The role

Beyond making urine, the kidney participates in hormonal regulation.

It helps regulate blood pressure and produces erythropoietin, which stimulates red blood cell production.

It contributes to vitamin D activation and the balance of minerals important for bone.

Kidney disease can therefore cause anaemia or bone disorders even without kidney pain.
