Graves' disease: Hi. Graves' disease is the most common. This is followed by subacute thyroiditis, which is followed by "toxic" (misnomer...not poisonous) or "hot" (misnomer...they're body temp) nodule(s). In there, you have to factor iatrogenic...usually thyroid cancer patients we deliberately make biochemically hyperthyroid. But good ol' Graves' is definitely in 1st place! Good luck!

Hyperthyroidism: Graves disease is an autoimmune disease most common in young women. Other common forms are toxic nodular goiter, subacute thyroiditis, post-partum thyroiditis, and of course overreplacement with thyroid hormone. There are other, less common forms of hyperthyroidism, some of which can be subtle. Best to have this evaluated by an endocrinologist or an internist who is familiar with this.
