A few words of thanks would be greatly appreciated.

Multinodular goiter - Definition


Goiter is an increase in the thyroid volume, visible in the form of a lump in the neck. In multinodular goiter, the volume increase is in limited areas and several nodules can be felt on palpation. This type of goiter progresses slowly and is then associated with a rise in thyroid hormone levels. In this case, it is manifested by signs of thyrotoxicosis: tremors, tachycardia, weight loss, diarrhea, sweating ... Numerous clinical signs are available that demonstrate an overall increase in a number of functions stimulated by thyroid hormones. An ultrasound or scintigraphy are necessary for the diagnosis, and suppression therapy is used to reduce the levels of thyroid hormones. The removal of the thyroid, or a thyroidectomy, is sometimes necessary.
