Goitre is a swelling in the neck resulting from an enlarged thyroid gland. Worldwide, over 90% of goitre cases are caused by iodine deficiency. A goiter can present as a palpable or visible enlargement of the thyroid gland at the base of the neck. It is 5-10 times more common in women. The most common symptom is the feeling of tenseness in the neck, trouble swallowing, cough and even Horner's sign. Ultrasound scan is necessary to evaluate the thyroid gland tissue. Goitre may be diagnosed via a thyroid function test. Sometimes, surgical treatment can be an option, while clinical monitoring is preferred.
