A patient can have hypertension for years without knowing. Defined as a state when the force of the blood against the arterial walls is too high, hypertension has varying degrees of severity, and tell-tale symptoms don’t always manifest early on. It has a variety of causes, many of which can be relieved with lifestyle modification or proper treatment from a specialist. Dr. Santiesteban specializes in the detection and treatment of hypertension and resistant hypertension — a subject he's published research on. He combines education, counseling, and pharmacology to get the best results for even the most complex conditions.
