This condition occurs when your immune system mistakenly attacks your thyroid gland, causing inflammation and enlargement.
This autoimmune disorder causes the overproduction of thyroid hormones, leading to hyperthyroidism and goitre.
These are growths on the thyroid gland that can be benign or malignant. In some cases, these nodules can cause the gland to enlarge and lead to goitre.
Although rare, thyroid cancer can cause goitre in some cases.
Some drugs, such as lithium and amiodarone, can interfere with thyroid function and lead to goitre.
