Thyroid disorders are more common in women and older adults and are often overlooked because of the slow progression of symptoms. Thyroid disorders are often misdiagnosed as neurological, cardiovascular, gastrointestinal or reproductive disorders. The main thyroid disorders include: hyperthyroidism (Graves’ disease, Plumer’s disease, etc.) hypothyroidism (hypothyroidism) thyroiditis (acute, subacute, chronic lymphatic) non-toxic goiter (endemic goiter, nodular goiter), thyroid tumors (benign, malignant).
