Prehypertension is the range between normal and high blood pressure. If it surpasses this range, it becomes hypertension, or high blood pressure. It should be taken seriously. It indicates you’re on the path to developing high blood pressure, which can lead to a wide range of health problems. But it can be reversed with lifestyle modifications like dietary changes, increased physical activity, and stress management. Your doctor can help you create a plan based on your risk factors and lifestyle. Checking your blood pressure is the only way to know if you have prehypertension. The general recommendation is to check it once every 2 years.
