My name is Jennifer, and I am the education nurse here at ITT Internal Medicine. Your doctor asked me to explain to you your diagnosis of hypertension. I will go over what hypertension is, how your cardiovascular system works and maintains homeostasis, how the rest of your body could be affected by hypertension, and what you can do to lower your blood pressure. Hypertension is a chronic medical condition where the pressure of blood in the arteries is elevated. Blood pressure is a measure of the force that blood pumps against the walls of the arteries, and will have two readings: the systolic pressure or the measure of the blood within the artery when the heart muscle is contracting, and the diastolic pressure or the pressure of the blood when the heart muscle is relaxing. It is read as systolic pressure over diastolic pressure. Hypertension is present when consistent readings are above 140 systolic over 90 diastolic. In hypertensive patients, usually both systolic and diastolic readings are both abnormally high. A normal blood pressure reading for an adult male would be under 120/80. Hypertension can be caused by many factors, and is considered a hereditary disease as well. This disease usually does not have one single identifiable cause because there are so many factors that can attribute to maintaining good cardio vascular health. Your cardiovascular system transports blood containing oxygen & nutrients throughout your body to your different organ systems, and carbon dioxide & waste to different organs for elimination from the body. Your heart acts as the pump to pump the blood through your arteries to your different organs, and back through your veins. When this is happening as it should and all your organs and systems are working independently to work together, your body achieves a balance known as homeostasis. When this is not happening, it is called a homeostatic imbalance. Your body uses a negative feedback system to maintain the state...
