Hypertension, also known as high blood pressure, is a common disorder where blood pressure is consistently higher than normal levels. It can be caused by factors like obesity, high salt intake, smoking, and excessive alcohol. While lifestyle changes like exercise, diet modifications, and stress management can help control hypertension, some people may require medication. Common drug classes used to treat hypertension include ACE inhibitors, calcium channel blockers, and diuretics, which work to relax blood vessels, widen blood vessels, or flush out excess salt and water respectively. Natural remedies incorporating potassium-rich foods, caffeine reduction, and dark chocolate consumption may also help lower high blood pressure.
