**Physiological hypertrophy** - an increase in the size of an organ or tissue without exceeding its functionality. Such hypertrophy can be associated with various reasons and have various consequences for the body.
Physiological hypertrophy is a reversible reaction of an organ or tissue to prolonged increased loads, helping to maintain the functional activity of organs (tissues). Physiological growth of tissues is normally commensurate with the capabilities of the body, and is therefore called physiological; as opposed to morphological (pathological) hypertrophy, organically caused by abnormal growth of a cell or tissue.
**Causes and main types of physiological hypertrophy.** Among the many reasons for this process are frequent repetition or chronic increase in loads. For example: Hypoxic factor and hyperthermia in combination with each other, that is, diseases of the respiratory system of the body; Negative effect of infectious lesions; Overload of the body with nitrates or other stimulating drugs; Complex negative impact of stress or psycho-emotional overload. The physiological influence of one hypertrophying structure has the ability to influence unrelated functional abilities of various organs and tissues. At the same time damaged
