Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle. In response to this pressure overload, the inner walls of the heart may respond by getting thicker.Pathophysiology & Clinical Presentation-Benign Prostatic Hypertrophy. Benign Prostatic Hyperplasia (BPH) is a common disorder characterized by the enlargement of the prostate gland over a prolonged period of time. Benign hyperplasia of the prostate develops in men around the age of 40-45 and slowly progresses until death (McCance & Huether, 2014). Muscle hypertrophy is the process of increasing your muscle mass by increasing the size of your muscle-fiber cells.
