In general, there are two components of blood pressure, namely systolic blood pressure and diastolic blood pressure. Systolic blood pressure is the upper number which is the driving force arising from the shrinking of the ventricle. While diastolic blood pressure is the bottom number which is the strength of holding on the walls of blood vessels as the heart relaxes between beats.

Contraction and relaxation in the heart causes pressure on the walls of the arteries or blood vessels. Blood pressure is said to be high in blood circulation if the circulation gets greater pressure as a result of artery narrowing, heart, or kidney disorders.

Blood pressure is considered high if it consistently stays at 140/90 mmHg or higher. The meaning consistent here is if the blood pressure check for three consecutive times within 2 weeks. So, if only one measured can not be categorized as suffering from high blood pressure or hypertension.

Blood pressure is usually not the same throughout the day. Blood pressure checks is best done when waking up early because blood pressure will rise once we do the activity. However, if necessary check blood pressure after activity, try to rest for 5 minutes before taking the checks.

High blood pressure is nicknamed “silent killer” because patients often do not experience any symptoms when high blood pressure, until one day suffered health problems due to damage to vital organs. Uncontrolled high blood pressure for years will damage the arteries throughout the body so that the walls are thickened and stiff. As a result of this thickening, the blood supply to the vital organs of the body is disrupted and eventually becomes damaged. Uncontrolled high blood pressure can be complicated in coronary heart disease, heart failure, stroke, and kidney failure.

Ninety-five percent of the causes of high blood pressure are unknown. Such types are called essential hypertension or primary hypertension. Moreover, high blood pressure can be due to kidney disorders, adrenal gland disorders, and thyroid.
