Why is there noticeable swelling in the front part of the neck of a person who has goiter?

Goiter is characterized by the enlargement of the thyroid gland, which is located in the front part of the neck. This swelling occurs due to an increase in the size of the thyroid tissue, often as a response to iodine deficiency, autoimmune diseases like Hashimoto's thyroiditis, or overproduction of thyroid hormones. The enlarged gland can create a visible bulge in the neck, leading to the noticeable swelling associated with goiter. Additionally, the swelling may compress surrounding structures, causing discomfort or difficulty in swallowing or breathing.
