The pressure in the arteries changes depending on what the heart is doing. When the heart squeezes, pumping blood into the arteries, the pressure increases. When the heart relaxes, the pressure decreases. When blood pressure is measured, the highest pressure (when the heart is squeezing) is called the systolic blood pressure. The lowest pressure (when the heart is relaxing) is called the diastolic blood pressure.
Blood pressure is written as two numbers. For example, in the picture at the right, the person's systolic blood pressure was 158. Their diastolic blood pressure was 99. This blood pressure is written as 158/99. It is said "158 over 99."
There are two types of hypertension, called “primary” and “secondary.” Primary hypertension means that the hypertension is not caused by any other disease or condition and it gradually develops over time with age. Secondary hypertension means that the hypertension is caused by another disease or conditions. Secondary hypertension tend to result in higher blood pressure than primary hypertension. In most cases (90-95%), hypertension is primary. Only a small amount of hypertension (5-10%) is secondary.
There are various health conditions that leads to secondary hypertension which includes: Obstructive sleep apnea, Kidney problems, Adrenal gland tumors, Thyroid problems, Certain defects you're born with (congenital) in blood vessels, Certain medications (birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs), Illegal drugs (cocaine and amphetamines).
