The hypertrophy occurs as a result of increased demand. Depending on the result of the removal of this demand the hypertrophy is divided into:
physiological hypertrophy – the tissues return to their initial state after the demand is removed,pathological hypertrophy – the tissues do not return to their initial state even after the demand is removed.
Depending on the reason that cause it the hypertrophy can be:
compensatory hypertrophy,regenerative hypertrophy,vicarious hypertrophy .The heart can also increase in size in healthy people – for example, athletes. With large physical loads, the cardiovascular load increases, which results in compensatory hypertrophy.
Hyperplastic growth may be result from different stimuli:
increased demand (e.g. for compensation of skin loss),hormonal dysfunctions,chronic inflammatory response,disease,compensation for damage.
An example for hyperplasia is the multiplication of milk-secreting glandular cells in the breasts, during pregnancy, thus preparing for breast feeding.
