In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. [1] It is distinguished from hyperplasia , in which the cells remain approximately the same size but increase in number. [ 2 ]
Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size (hypertrophy). [7] Hyperplasia is different from hypertrophy in that the adaptive cell change in hypertrophy is an increase in the size of cells, whereas hyperplasia involves an increase in the number of cells. [8]
Eccentric hypertrophy is generally regarded as healthy, or physiologic hypertrophy and is often termed "athlete's heart." It is the normal response to healthy exercise or pregnancy, [6] which results in an increase in the heart's muscle mass and pumping ability. It is a response to 'volume-overload', either as a result of increased blood return ...
Left ventricular hypertrophy. Hypertensive heart disease is the result of structural and functional adaptations [18] leading to left ventricular hypertrophy, [19] [20] [21] diastolic dysfunction, [18] [20] CHF (Congestive Heart Failure), abnormalities of blood flow due to atherosclerotic coronary artery disease [18] and microvascular disease, [10] [19] and cardiac arrhythmias.

Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
