What Causes High Blood Pressure? (kidshealth.org)

Blood pressure is a measure of the force that your heart uses to pump blood around your body. (www.nhs.uk)
Left untreated, high blood pressure can increase your risk of developing a number of serious long-term health conditions, including coronary heart disease. (www.nhs.uk)
Your blood pressure is highest when your heart beats, pumping the blood. (medlineplus.gov)
When your heart is at rest, between beats, your blood pressure falls. (medlineplus.gov)
One pump, the 'right heart,' receives blood which has just come from the body. (cdc.gov)
The blood then returns to the 'left heart' via the pulmonary vein. (cdc.gov)
Veins are the series of vessels which carry blood from various parts of the body back to the heart. (cdc.gov)
One-way valves in the veins aid the blood on its return trip to the heart. (cdc.gov)
Systolic blood pressure is the degree of force when the heart is pumping (contracting). (cdc.gov)
Patients at low or intermediate risk of heart events, on the other hand, might not need to be so aggressive in treating their high blood pressure with medications. (hopkinsmedicine.org)
The upper number represents systolic blood pressure - pressure when the heart is contracting. (medicalnewstoday.com)
To compensate, blood vessels outside of the digestive tract constrict, causing the heart to beat faster and more forcefully. (medicalnewstoday.com)
According to the American Heart Association (AHA) , saturated fat increases the amount of low-density lipoprotein (LDL), or "bad," cholesterol in the blood. (medicalnewstoday.com)
The heart compensates by pumping blood more forcefully, resulting in an increase in blood pressure. (medicalnewstoday.com)
