The enlarged cysts can cause pressure against nephrons, resulting in renal ischemia and anoxia.When kidneys can not get enough oxygen,more renin will be made by kidneys,thus contracting renal blood vessels.As a result,high blood pressure will result.High blood pressure can contribute to dizziness in PKD.


Anemia more commonly occurs in advanced stage of PKD. Healthy kidneys can produce a hormone called EPO.EPO can stimulate the bone marrow to produce red blood cells.However, when kidneys are impaired, they become unable to produce EPO adequately.As a result, less red blood cells are made by bone marrow. Red blood cells can distribute oxygen to body tissues and cells. When insufficient oxygen is supplied to brain cells, the patients may have dizziness.
