Catabolic Stress Hormone

Meaning

A catabolic stress hormone is a signaling molecule released by the endocrine system, primarily in response to physiological or psychological stressors. Its core function involves breaking down complex molecules, such as proteins and fats, into simpler substances like glucose for immediate energy use. This process is essential for survival during periods of acute demand, helping the body rapidly mobilize energy reserves. Cortisol, a glucocorticoid released by the adrenal cortex, is the most recognized example within this category. Prolonged elevation of these hormones, however, can lead to adverse health outcomes, including muscle wasting and impaired immune function.
