Endocrine glands release hormones into circulation to act on cells with appropriate receptors. Most endocrine axes use negative feedback, where the downstream effect reduces further stimulation. Hormone action is slower than direct nerve signaling in many contexts but can have widespread, longer-lasting effects.
| Organ/gland | High-yield hormones/functions |
|---|---|
| Hypothalamus | Links nervous/endocrine control; releasing/inhibiting hormones; makes ADH and oxytocin that are released from posterior pituitary. |
| Anterior pituitary | TSH, ACTH, GH, prolactin, FSH, LH. |
| Posterior pituitary | Stores/releases ADH and oxytocin. |
| Thyroid | T3/T4 regulate metabolic activity; calcitonin participates in calcium regulation. |
| Parathyroids | PTH raises blood calcium through coordinated effects on bone, kidney and vitamin-D-related intestinal absorption. |
| Adrenal cortex | Cortisol, aldosterone and adrenal androgens. |
| Adrenal medulla | Epinephrine/norepinephrine in sympathetic stress response. |
| Pancreatic islets | Insulin lowers blood glucose by promoting uptake/storage; glucagon raises it through mobilization. |
| Pineal | Melatonin and circadian timing. |
| Ovaries/testes | Sex hormones involved in reproduction and many body-wide effects. |
Massage decisions often depend less on the label “diabetes” than on complications: peripheral neuropathy, wounds, impaired circulation, glucose instability and medication timing. Recognize hypoglycemia symptoms and thermal-injury risk when sensation is reduced.
Massage does not manually “balance hormones” in a predictable disease-treating way. Relaxation and stress responses are real areas of study, but therapeutic claims should match evidence and scope.
