Even so, the thyroid will keep enlarging, and keep producing hormone. The end result can be a goiter.
In Hashimoto's thyroiditis, an autoimmune condition, the thyroid can be damaged by your immune system. Enough damage can lead to inadequate production of hormone.
To counteract this, the pituitary sends out more TSH to stimulate the thyroid. Again, the thyroid is prompted to grow, and a goiter may be the result.
To avoid goiter from dietary causes, make a point of getting enough iodine, through iodized salt, seafood or seaweed. Shellfish are rich sources of iodine. People living near the coast may get iodine from local produce, as well as from local dairy products.
In rare cases, goiters can result from too much iodine. If this is your situation, stay away from iodized salt, seaweed, shellfish and any iodine supplementation.
