Low blood pressure is high and high pressure is also high, and if all three measurements taken on non-same day are significantly higher than the normal standard, i.e., systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg is considered to be high blood pressure, and is not a case of blood stickiness. Hypertension is a chronic condition in which the pressure on the walls of blood vessels caused by the flow of blood through the vessels is persistently higher than normal. A proportion of patients with hypertension have no obvious discomfort, and those who do may present with headaches, paroxysmal dizziness, numbness of the scalp, and chest tightness and discomfort. Blood viscosity is medically known as hyperviscosity. Factors affecting blood viscosity include blood cellular factors such as the number, size, and shape of blood cells, plasma factors such as blood glucose and lipids in the blood, and vascular factors such as the length and diameter of blood vessels. Elevated blood pressure is not the result of blood thickening, but blood thickening may lead to elevated blood pressure. Patients with elevated blood pressure should go to the cardiovascular medicine department of the hospital in time and be treated under the guidance of the doctor so as not to affect their personal health.
