Hypertension is a common problem in modern people. When the heart is pumping out, the blood volume is larger, and the narrower the arterial diameter, the higher the blood pressure.
If the blood pressure rises more than 130/80 mm Hg for a long time, the blood exerts too much pressure on the blood vessels, which causes many health problems. (The American Heart Association AHA redefines hypertension in 2017, indicating that early treatment should be given when blood pressure rises to 130/80 mm Hg.)
people with high blood pressure for a long time will say, "The blood pressure is relatively high, but I don't feel uncomfortable at all!"
Indeed, patients with high blood pressure are likely to experience years of asymptomatic days, but not feeling uncomfortable does not mean that hypertension does not exist. During this time, high blood pressure continues to damage the blood vessels and heart.
If the blood pressure becomes high but ignores it, the body organs will gradually be damaged. The higher the blood pressure and the longer it lasts, the stronger the damage.
