What is the danger zone of high blood pressure?

As a medical professional with expertise in cardiology, I can tell you that high blood pressure, also known as hypertension, is a serious health condition that can lead to significant health risks if not properly managed. The danger zone of high blood pressure is typically considered to be when the systolic pressure (the top number) is consistently above 140 mm Hg and/or the diastolic pressure (the bottom number) is consistently above 90 mm Hg. However, these thresholds can vary depending on individual factors, and some guidelines may have slightly different ranges. When blood pressure remains in the high range over time, it can cause damage to various parts of the body, including the heart, blood vessels, kidneys, and eyes. This is because high blood pressure places extra strain on the arteries and can lead to atherosclerosis (hardening of the arteries), which in turn increases the risk of heart attack, stroke, kidney failure, and other serious health issues. It's important for individuals with high blood pressure to work closely with their healthcare providers to manage their condition through lifestyle changes, medication, and regular monitoring. This can help to reduce the risk of reaching the danger zone and experiencing the associated health complications.

Physicians recommend that you maintain blood pressure at or below 120/80 mmHg, but high blood pressure is medically defined as any reading higher than 140/90 mmHg. Readings of 121 to 139 systolic or 81 to 89 diastolic are considered prehypertension, a warning that blood pressure may soon rise into the danger zone.
