Thyrotoxicosis

Clinical syndrome resulting from elevated free T3, free T4, or both, leading to hypermetabolic peripheral tissues.

Primary Toxic Goitre (Grave’s Disease)

An autoimmune disease where abnormal thyroid-stimulating antibodies cause the thyroid to overproduce hormones.

Toxic Nodule (Autonomous nodule)

Hyperthyroidism caused by a single, overactive thyroid nodule, often noted in younger patients with a history of a long-standing nodule.

Hyperthyroidism

Clinical syndrome caused by increased levels of thyroid hormones being produced and released within the body.
