Types Of Hypertrophy:

Physiological Hypertrophy: It is the increase in the size of the cell or muscle due to heavy work or exercise. It has further two types muscular hypertrophy and ventricular hypertrophy. Muscular hypertrophy skeletal muscle is due to strength training exercise. Ventricular hypertrophy is an increase in the heart muscle due to increase exercise.

Pathological Hypertrophy: This occurs when there are pathological changes in the cell, tissue, and organ. Such as ventricular hypertrophy due to high blood pressure.

Compensatory Hypertrophy: This type of hypertrophy occurs when any organ compensates for the dysfunction or any loss of another organ of the same organ. For example, when there is hypertrophy of one kidney, the other kidney stops working.

Main Difference Between Atrophy And Hypertrophy:

-Atrophy is the decrease in the cell, tissue, organ, or any body part.
-Hypertrophy is the increase in the cell, tissue, organ, or any body part.

-Atrophy is due to a lack of movement of organs and tissues.
-Hypertrophy is due to the excess movement of organs and tissues.

-Chronic malnutrition and various chronic diseases are the cause of atrophy.
-Hypertrophy can be adaptive or compensatory.
