Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
The heart is located in the center of the chest, with part of it tipped slightly so that it taps against the left side of the chest.
When blood is exposed to air, it clots. Heparin allows the blood to come in direct contact with air without clotting.
More than one-third of adult Americans are obese. Diseases that kill the largest number of people annually, such as heart disease, cancer, diabetes, stroke, and hypertension, can be attributed to diet.
Excessive alcohol use costs the country approximately $235 billion every year.
