Physiological Pulsatility

Meaning

Physiological Pulsatility refers to the characteristic, rhythmic, and intermittent pattern of secretion exhibited by many key endocrine hormones, particularly those originating from the hypothalamic-pituitary axis, such as GnRH, LH, FSH, and Growth Hormone. This non-continuous release pattern, occurring in discrete bursts or pulses over specific time intervals, is essential for maintaining the sensitivity and proper function of target tissue receptors. Disruption of this natural pulsatility, often seen in conditions of chronic stress or disease, can lead to receptor desensitization and subsequent hormonal dysregulation, necessitating a clinical approach that respects this natural rhythm.
