how hypertension affects your homeostassi?

Hypertension alters your homeostasis a little. Your body becomes used to the higher pressures, despite the adverse effects on blood vessels (wear and tear, atherosclerosis, aneurysm).
There is increased peripheral vascular resistance as the systemic capillary beds compensate. This causes left ventricular hypertrophy of the cardiac muscle.
In some cases, particularly in long standing hypertension in the elderly, the adjustments to homeostasis can be so entrenched that lowering blood pressure TOO QUICKLY can be detrimental. It has previously been documented to result in cerebral infarction if cerebral perfusion pressure drops (CPP = MAP - ICP and as the brain gets used to a high MAP, mean arterial pressure, it doesn't cope well with a sudden drop in MAP and consequently CPP - leading to no perfusion of the brain and thus ischaemia).
