Thyroid hormone changes and psychological response to high altitude stress: effect of ethnicity

Sachidhanandam Meenakshi , Arumugam Suresh , Ray UdaySankar

Objective: Acclimatization to high-altitude is a dynamic process affecting the neuro-endocrine and physiological systems. Psychological well-being is also influenced by hypobaric-hypoxia. Psychic stress is known to influence the hypothalamo–pituitary–adrenal/thyroid axis. However, the involvement/contribution of ‘psychological-performance’ on hormone changes at high-altitude is not known. The objective of this study was to examine: i) the effect of ethnicit...

Altitude acclimatization: plasma AVP response and physiological changes

Sachidhanandam Meenakshi , Kumar Salthan Ashok , Singh Som Nath , Ray UdaySankar

Background: Arginine vasopressin (AVP) changes during altitude acclimatization is of clinical interest as increases in their plasma levels (with reference to sea-level (SL)) have been associated with fluid retention accompanied by elevated plasma cortisol levels. Studies have reported no change/ decrease in plasma AVP during ‘normal’ acclimatization. This study was conducted to evaluate plasma AVP changes and the associated physiological changes during chronic exposu...

Stress hormone response in men at high altitude: effect of ethnicity

Sachidhanandam Meenakshi , Nath Singh Som , Kumar Salhan Ashok , Sankar Ray Uday

Background and objective: Adaptive process to hypoxia of altitude involves changes in the homeostatic steady state of several endocrine variables which precede and contribute- to many physiologic adaptations. Physiologic responses to altitude-stress exhibit ethnic variation. However, there has been limited characterization of ‘ethnicity effect’ on endocrine responses to high-altitude stress. This is true for enzyme-immunoassay method (EIA) of plasma hormone analysis....
