Goiter: Risk Factors, Symptoms, Diagnosis, Treatment

Overview

A goiter is an abnormal enlargement of the thyroid gland. The thyroid gland is a butterfly-shaped endocrine gland which is located in the lower front of the neck. The thyroid gland can make thyroid hormones which can help the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as usual. Generally, goiters are painless, while large ones can lead to symptoms that may influence your normal life, such as coughing or difficuly breathing or swallowing.

Goiter is more common in women than in men, especially in women before menopause. About 200 million people have goiter because of iodine deficiency, even if it is almost disappeared in America because of adequate iodine intake.

Treatment

Depending on the size, cause and symptoms of your goiter, doctors may recommend different treatment options, including:

  • Observation and regular inspection: This is for small goiters that cause no problems on your daily life.
  • Medications: If your goiter is caused by some diseases, such as hypothyroidism and hyperthyroidism, your doctors may give you some medications. For example, levothyroxine for hypothyroidism, methimazole or propylthiouracil for hyperthyroidism. Sometimes beta blockers may also be used, including propranolol, atenolol, metoprolol and nadolol.
  • Surgery: If your goiter is so large that you cannot breathe or swallow as usual, your doctor may recommend surgery to remove all of or part of the thyroid gland (thyroidectomy or subtotal thyroidectomy). This can prevent thyroid cancer, but you also cannot produce the thyroid hormone to meet your body’s need after the procedure. You may have to take thyroid hormone medications for life.

Please consult your doctors for your treatment.
