WHO staging of goiter
| Stage | Clinical findings |
| 0 | No goiter |
| Ia | Goiter palpable, but not visible with reclined (= extension of head toward back) neck |
| Ib | Goiter palpable in reclined (“backward leaning”) neck |
| II | Goiter visible with normal posture of the head |
| III | Goiter with signs of local congestion/compression (stridor/whistling breathing, upper influence congestion (OES), tracheomalacia/disease in which the cartilaginous braces of the trachea and/or larynx are too soft) |
Other divisions
Classification according to function: euthyroid goiter (normal metabolic values) is distinguished from hypothyroid goiter (in hypothyroidism) and hyperthyroid goiter or toxic goiter (in hyperthyroidism).
Epidemiologic classification, i.e., by occurrence: This is classified/defined as follows: if more than 10% of the population is affected within an area, it is called endemic goiter; otherwise, it is called sporadic goiter.
