In case of hypertension, artery walls become overloaded. Such a state has a very negative effect not only on blood vessels, but on other vital body organs, too. The degree of the damage depends on the exact level of blood pressure and duration of hypertension in case it is uncontrolled.

Some of possible side effects and outcomes are listed below.

Hypertension that is not treated may result in eye problems and even loss of sight due to narrowed, torn, or thickened optic blood vessels.

Heart muscle thickens in response to overloads and elevated pressure. Modified muscle may have problems with normal blood circulation. A heart failure may occur in severe cases.

Blood vessels become thicker and harder (atherosclerosis). Damaged arteries are directly associated with heart attack, heart stroke and other heart related problems.
