Endocrinology
The medical specialty concerned with hormones and the glands that secrete them — the parent discipline for peptide and metabolic medicine.
Definition
Endocrinology studies the endocrine glands (pituitary, thyroid, adrenal, pancreas, gonads) and the hormones they produce. Peptide medicine operates primarily at the hypothalamic-pituitary axis, the thyroid axis, and the gut-brain metabolic loop — domains where small signalling molecules have outsized effects. Metabolic medicine overlaps endocrinology but adds explicit focus on obesity, insulin resistance and metabolic syndrome.

HPA AxisHypothalamic-Pituitary-Adrenal Axis
The feedback loop between hypothalamus, pituitary and adrenals that governs cortisol and stress response.
MechanismGrowth HormoneGH
A pituitary-secreted hormone that drives protein synthesis, fat metabolism and tissue repair — released in pulses, peaking at night.
Clinical ConceptMetabolic Syndrome
A cluster of five conditions — central obesity, hypertension, dyslipidaemia, hyperglycaemia, low HDL — that together multiply cardiovascular risk.
