high blood pressure
Medically known as hypertension, this condition occurs when the heart needs to work harder, exerting a higher pressure on the veins and arteries, to get the blood to circulate throughout the body. Aggravating causes include smoking, obesity, a high-sodium diet or genetic predisposition. Hypertension is defined as an average blood pressure measurement of 140 (systolic) over 90 (diastolic) or higher on at least two separate readings.
