The treatment of hypertension is no longer limited to the simple prescription of pharmaceuticals. For many patients, maximal medical therapy is insufficient to adequately treat refractory hypertension. In addition, some patients may prefer to explore therapies that do not involve drugs as an initial step. Utilizing our broadening understanding of the physiology of hypertension, new technology and interventions have been developed that allow for treatments that do not rely on medications. In addition, dietary supplements and modification, as well as herbal supplements, may be useful under the right circumstances. Lifestyle modification remains a necessary part of treatment for all patients with hypertension. This article will review the evidence behind some available nondrug interventions for the treatment of hypertension.
