High blood pressure is also known as hypertension and refers to the force of blood against the walls of your arteries being too high. Alternative terms for high blood pressure include elevated blood pressure, increased blood pressure, and excessive arterial pressure. Sometimes medical professionals will refer to it simply as "hypertension" or abbreviated as "HTN." Other colloquial terms for high blood pressure may include "the silent killer" or "the ticking time bomb" as it often has no symptoms but can lead to serious health problems if left untreated. Regardless of how it is referred to, it is important for people to monitor their blood pressure and take steps to manage it if necessary.
