A goiter is an enlargement of the thyroid gland which is situated at the front of the throat, below the larynx. It is made up of two lobes on either side of the windpipe, joined in front by an isthmus. The thyroid gland secretes hormones that regulate metabolic processes, such as growth and energy expenditure. This gland is controlled by the pituitary gland, which is located in the brain. The pituitary prompts the thyroid to make its hormones including thyroxine (T4) and tri-iodothyronine (T3) by releasing a thyroid stimulating hormone (TSH). However, if a persons diet is too low in iodine the thyroid can't manufacture hormones. Never the less the pituitary keeps sending chemical messages to the thyroid, without any result . The thyroid gland then enlarges as it unsucsesfuly trys tos to comply with the pituitary's glands instruction. Apart from iodine deficiency, other causes of goiter involve conditions of the thyroid - such as nodules, cancer, hyperthyroidism and hypothyroidism.
The symptoms of a goiter include: * Enlargement of the throat, ranging from a small lump to a huge mass. * Swallowing problems, if the goiter is large enough to press on the esophagus. * Breathing problems, if the goiter is large enough to press on the windpipe (trachea).
