High blood pressure is also known as the silent killer because it’s largely a symptomless disease. The fact that high blood pressure doesn’t have symptoms (you can’t see or feel it) is what makes high blood pressure so insidious; left untreated, it will kill you. In fact, high blood pressure remains the most common medical diagnosis in the United States and the condition that doctors write the most prescriptions for. It’s also the number one cause of stroke and kidney disease and a principal cause of heart disease and blindness.

Overweight people are five times more likely to have high blood pressure than normal weight individuals. The more body fat a person carries, the more blood is needed to provide the tissue with oxygen and nutrients, resulting in higher blood pressure. Researchers have found that extra body fat activates the two underlying origins of elevated pressure: an overactive sympathetic nervous system and an overactive renin (blood pressure hormone) system. The good news is that if you lose body fat, your blood pressure will significantly go down.
