"Blood pressure guidelines are not updated at regular intervals. Instead, they are changed when sufficient new evidence suggests the old ones weren't accurate or relevant anymore," says Dr. Paul Conlin, an endocrinologist with Harvard-affiliated VA Boston Healthcare System and Brigham and Women's Hospital. "The goal now with the new guidelines is to help people address high blood pressure — and the problems that may accompany it like heart attack and stroke — much earlier."
Headaches strike over 90% of adults each year. You may be able to wait out some and let them pass, but others may be a sign that your body is asking you to take action. There is a chance that your headache could be a symptom of high blood pressure. If there are no other causes of your headache, you should ask your healthcare provider about getting your blood pressure checked.
