ANATOMY

Detailed explanation-1: -A goitre is a lump or swelling at the front of the neck caused by a swollen thyroid. The thyroid is a small gland in your neck that makes hormones. Goitres are not usually serious but should be checked by a GP.

Detailed explanation-2: -Iodine deficiency is the most common cause of goiter. The body needs iodine to produce thyroid hormone. If you do not have enough iodine in your diet, the thyroid gets larger to try and capture all the iodine it can, so it can make the right amount of thyroid hormone.

Detailed explanation-3: -An overactive thyroid may be treated with an anti-thyroid drug that disrupts hormone production. The most commonly used drug, methimazole (Tapazole), may also reduce the size of the goiter.

Detailed explanation-4: -A goiter is usually painless but may cause pressure-related symptoms, including: A feeling of neck fullness or tightness. Difficulty swallowing. Difficulty breathing.

Detailed explanation-5: -Thyroiditis is swelling (inflammation) of the thyroid gland. It causes either unusually high or low levels of thyroid hormones in the blood. The thyroid is a butterfly-shaped gland in the neck. It produces hormones that control the body’s growth and metabolism.
