The medical abbreviation "HTN" stands for "Hypertension". Hypertension, also known as high blood pressure, is a common medical condition in which the force of blood against the walls of the arteries is consistently too high. It can lead to serious health problems such as heart disease, stroke, and kidney disease.
Blood pressure is measured with two numbers: systolic pressure (the higher number) and diastolic pressure (the lower number). Normal blood pressure is typically considered to be less than 120/80 mm Hg. Hypertension is defined as a consistent blood pressure reading of 130/80 mm Hg or higher.
Treatment for hypertension may involve lifestyle changes such as weight loss, exercise, and a healthy diet, as well as medications such as diuretics, ACE inhibitors, and beta blockers.
