Hyperthyroidism

Triiodothyronine (T3) molecular structure

Hyperthyroidism is excess thyroid hormone effect: high pulse, heat, weight loss, anxiety. Graves disease and excess dosing are common causes. True hyper differs from compensatory high pulse in hypothyroidism with adrenaline.

Peat's view

Peat pointed to blood viscosity as a marker of the thyroid-progesterone-estrogen axis: hyperthyroid people have unusually fluid blood, while hypothyroid people (low progesterone, high estrogen) have abnormally viscous blood and greater susceptibility to heart disease and cancer.

Graves' disease

Graves' disease is an autoimmune condition in which antibodies stimulate the thyroid-stimulating hormone receptor directly, causing hyperthyroidism independent of normal pituitary control; it is the most common cause of hyperthyroidism. No specific Peat commentary naming Graves' disease was found; his general framework distinguishes true hyperthyroid states like Graves from the compensatory high-adrenaline states that mimic some hyperthyroid symptoms in genuinely hypothyroid people. The two can look similar symptomatically (elevated pulse, anxiety, heat intolerance) but require opposite treatment approaches, which is why self-diagnosis from symptoms alone is unreliable here: Graves' disease requires medical diagnosis (antibody testing, not just symptoms or a single temperature/pulse reading) and medical management (antithyroid drugs, radioactive iodine, or surgery), not something to self-manage with diet alone. Third-generation TSH-receptor-antibody (TRAb) assays have over 95% sensitivity and specificity for diagnosing Graves' disease; a TRAb level above 12 IU/l at diagnosis predicts a 60% relapse risk at 2 years and 84% at 4 years after stopping antithyroid drugs.

Practice

Medical diagnosis required. Do not self-treat with random thyroid doses. See Thyroid, Hypothyroidism, Adrenaline, Pulse, Harm reduction.
