How to shrink goiters?
However, a large nodular goiter with a lot of internal scar tissue will not shrink with treatment. If the goiter is uncomfortable, causes overproduction of thyroid hormone unresponsive to medications, is large enough that it causes symptoms because of its size, or becomes cancerous, the entire thyroid gland may have to be surgically removed.
How does nontoxic goiter affect the body?
Sometimes, goiter that begins as nontoxic can become toxic and cause your thyroid to produce more hormones than your body needs. Your thyroid controls many of your bodily functions, and a thyroid that is overworking or underworking can result in unexpected weight loss or gain, arrhythmias, changes in appetite or sleep habits, and fatigue.
