In nature, hypertrophy can be divided into two types: physiological hypertrophy or pathological hypertrophy.
In terms of reasons, they can be divided into types such as compensatory hypertrophy and endocrine hypertrophy.
Hypertrophy is caused by overloading of the corresponding organs and tissues, which is called compensatory hypertrophy. For example, under physiological conditions, the upper limb bones of weightlifters
Concentric myocardial hypertrophy
Muscle growth and hypertrophy; under pathological conditions, left ventricular myocardial hypertrophy caused by increased myocardial postload or peripheral myocardial function compensation after partial myocardial necrosis of the left ventricle (see the right picture)
Hypertrophy can also be caused by the effect of endocrine hormones on effectors, called endocrine hypertrophy. For example, under physiological conditions, uterine smooth muscle hypertrophy caused by progesterone and its receptors stimulates increased smooth muscle protein synthesis during pregnancy; under pathological conditions, thyroid follicle epithelial cell hypertrophy caused by increased thyroid hormone secretion.
While the parenchymal cells atrophy, the interstitial adipocytes can proliferate to maintain the original volume of the organs, and even cause the organs and tissues to increase in size, which is called pseudohypertrophy.
