Goiter
Moderate
Goiter is an enlargement of the thyroid gland, which is located at the front of the neck and produces hormones that regulate metabolism. A goiter may involve the entire thyroid gland or may occur with one or more thyroid nodules. Some people have no symptoms other than visible or palpable enlargement of the neck. A large goiter can sometimes press on the windpipe or esophagus and cause breathing, coughing, hoarseness, or swallowing problems.

When to Seek Medical Attention
Seek prompt medical assessment for a rapidly enlarging neck swelling, new difficulty swallowing or breathing, significant voice changes, or symptoms that develop suddenly. Severe breathing difficulty or inability to swallow requires emergency medical attention.

Overview
Goiter is an enlargement of the thyroid gland, which is located at the front of the neck and produces hormones that regulate metabolism. A goiter may involve the entire thyroid gland or may occur with one or more thyroid nodules. Some people have no symptoms other than visible or palpable enlargement of the neck. A large goiter can sometimes press on the windpipe or esophagus and cause breathing, coughing, hoarseness, or swallowing problems.

Causes 4
Iodine deficiency is an important cause of simple goiter because the thyroid needs iodine to produce thyroid hormones. Other causes include autoimmune thyroid diseases, medicines such as lithium or amiodarone, certain infections, smoking, and thyroid nodules that produce excessive hormone. Goiter can also occur when the thyroid is underactive or overactive. The cause therefore needs to be evaluated rather than assuming that every enlarged thyroid is due to iodine deficiency.

Risk Factors
Risk factors vary according to the underlying cause. Being over age 40, having a family history of goiter, and living or having grown up in an area where iodine deficiency occurs can increase risk of some types. Women are more frequently affected by simple goiter. Autoimmune thyroid disease, certain medicines, smoking, and conditions that cause thyroid nodules or abnormal thyroid hormone production can also increase the likelihood of thyroid enlargement.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Evaluation of a goiter begins with examination of the neck and thyroid gland. Blood tests can measure thyroid-stimulating hormone and thyroid hormones such as free T4. Thyroid ultrasound can identify enlargement and examine nodules or other structural changes. A thyroid scan and radioactive iodine uptake study may be used in selected cases to assess thyroid function. If a nodule has suspicious features, a biopsy may be recommended to determine whether cancer is present.
Prevention
Key Prevention Tips
Adequate iodine intake can prevent many cases of simple goiter caused by iodine deficiency
Using iodized salt appropriately is an established way to maintain adequate iodine intake in populations where deficiency is a concern
Other causes, such as autoimmune thyroid disease or genetic susceptibility, cannot always be prevented
Avoiding unnecessary exposure to factors that affect thyroid function and obtaining medical evaluation for persistent neck swelling can help identify thyroid disorders early
