The damage to glomerular artery and nephrons due to hypertension is focal, but kidney function decline in the late term is progressive. On one hand, high blood pressure can impair kidneys, and kidney damage aggravates hypertension; they two form a vicious circle, and cause pathological changes in normal small artery and nephrons. On the other hand, hypertension induced nephrons injury can cause compensatory high perfusion and high filtration in remaining normal nephrons.
The purpose of hypertension treatment is controlling blood pressure in order to protect critical organs from damage which may target the brain, heart, kidneys and eyes. When blood vessels burst in the brain due to untreated high blood pressure this often results in strokes.ide effects of certain medications, for example, stop smoking products and certain organ transplant drugs are also responsible for secondary hypertension. How to treat hypertension of a secondary nature will therefore involve dealing with the underlying causes involved in order to eliminate the high blood pressure.
