A goitre, or goiter, is a swelling in the neck resulting from an enlarged thyroid gland. [ 1 ] [ 2 ] A goitre can be associated with a thyroid that is not functioning properly. Worldwide, over 90% of goitre cases are caused by iodine deficiency . [ 3 ]
The signs and symptoms of Graves disease virtually all result from the direct and indirect effects of hyperthyroidism, with main exceptions being Graves ophthalmopathy, goiter, and pretibial myxedema (which are caused by the autoimmune processes of the disease).
Although it is true that in most patients ophthalmopathy, goiter, and symptoms of thyrotoxicosis appear more or less coincidentally, it is also true that in certain cases eye signs may appear long before thyrotoxicosis is evident, or become worse when the thyrotoxicosis is subsiding or has been controlled by treatment.

Iodine deficiency causes gradual enlargement of the thyroid gland, referred to as a goiter. Poor length growth is apparent as early as the first year of life. Adult stature without treatment ranges from 100 to 160 cm (3 ft 3 in to 5 ft 3 in), depending on severity, sex, and other genetic factors.
Depiction of a goiter. Early stages of autoimmune thyroiditis may have a normal physical exam with or without a goiter. [13] A goiter is a diffuse, often symmetric, swelling of the thyroid gland visible in the anterior neck that may develop. [13]
Goiter is the general enlargement of the thyroid that can be associated with many thyroid diseases. The main reason this happens is because of increased signaling to the thyroid by way of TSH receptors to try to make it produce more thyroid hormone. [9] This causes increased vascularity and increase in size (hypertrophy) of the gland. [9]
Hashimoto's thyroiditis is also known as chronic lymphocytic thyroiditis, and patients with this disease often complain about difficulty swallowing. This condition may be so mild at first that the disease goes unnoticed for years. The first symptom that shows signs of Hashimoto's thyroiditis is a goiter on the front of the neck.
[1] [7] Other causes include multinodular goiter, toxic adenoma, inflammation of the thyroid, eating too much iodine, and too much synthetic thyroid hormone. [1] [2] A less common cause is a pituitary adenoma. [1] The diagnosis may be suspected based on signs and symptoms and then confirmed with blood tests. [1]
