Blood pressure is the force blood creates on the artery walls. Blood pressure is typically stated using a fraction. The top number (systolic pressure) it is the pressure on the arteries with heart contracts. The bottom number (diastolic pressure) is the pressure between heartbeats (when it is resting).
Eating an unhealthy diet, being overweight, drinking large amounts of alcohol frequently, and smoking, stress, age, heredity are all factors that can raise someone's blood pressure. A person can have high blood pressure and have few or no symptoms, giving it the nickname of "silent killer". Usually the only way to find out if a person has high blood pressure is to have it tested. Taking all medications as prescribed, exercising regularly, maintaining a healthy weight, limiting salt intake, stop smoking and minimizing alcohol use are simple ways to reduce high blood pressure, once it's discovered.
