Goitre, sometimes also spelled goiter, is a growth in or enlargement of the thyroid gland. If a person has a goiter, it almost always affects the function of the thyroid gland. The vast majority of goiters are benign, and an iodine deficiency causes up to 90 percent of them. Goiters are especially prevalent in areas of the world where iodine is not added to table salt. Symptoms of goiter, in addition to a lump in the neck, include weight loss or gain and heart palpitations.
Medications help to reduce swelling and inflammation, and antithyroid agents. The medication suggested by your doctor for treating your goiter will depend on the cause of your condition.
