A goitre or goiter is a swelling at the throat caused by an enlarged thyroid gland. The expression can be used to refer to thyroid gland. A goitre is connected with a thyroid that's not functioning correctly.

Worldwide, over 90 percent of goitre cases are brought on by iodine deficiency. The expression is by the Latin gutteria. Many goitres are of a benign character.

A goiter (GOI-tur) is an abnormal enlargement of your thyroid gland. Your thyroid gland is a butterfly-shaped gland situated in the base of the throat just below your Adam's apple. Though goiters are often painless, a massive goiter can make a cough and also make it hard for you to breathe or swallow.

The most usual cause of goiters globally is too little iodine in the diet. In america, in which the usage of iodized salt is more ordinary, a goiter is more commonly as a result of over- or underproduction of thyroid hormones or into nodules that grow from the gland itself.

Treatment is based on the size of the goiter, your symptoms and the underlying cause. Little goiters which are not noticeable and do not cause difficulties typically don't require therapy.

Goiter Causes

A goiter (GOI-tur) is an abnormal enlargement of your thyroid gland. Your thyroid gland produces two hormones -- thyroxine (T-4) and triiodothyronine (T-3). These hormones circulate in your blood and help regulate your metabolism. They keep the pace at which your body uses fats and carbohydrates, help control your body temperature, influence your heart rate, and also help regulate the production of proteins.

Your thyroid gland also produces calcitonin -- a hormone that helps regulate the amount of calcium in your blood.

Your pituitary gland and hypothalamus control the pace at which these hormones are produced and released.

The procedure starts when the hypothalamus -- a place at the bottom of the brain that acts as a thermostat for your entire system -- indicates your adrenal gland to create a hormone called thyroid-stimulating hormone (TSH). Your thyroid gland -- also situated in the bottom of the mind -- releases a specific amount of TSH, based on how much thyroxine and T-3 are on your own blood. Your thyroid gland, in turn, regulates its production of hormones based on the amount of TSH it receives from the pituitary gland

Having a goiter does not automatically indicate that your thyroid gland is not working normally. Even if it is enlarged, your thyroid can produce normal levels of hormones. It may also, however, create too much or too little thyroxine and T-3.

A number of factors can cause your thyroid gland to enlarge. Among the most common are:

Multinodular goiter. In this condition, several solid or fluid-filled lumps called nodules develop in both sides of your thyroid, resulting in overall enlargement of the gland.
Solitary thyroid nodules. In this case, a single nodule develops in one part of your thyroid gland. Most nodules are noncancerous (benign) and don't lead to cancer.
Thyroid cancer. Thyroid cancer is far less common than benign thyroid nodules. A biopsy of a thyroid nodule is very accurate in determining if it's cancerous.
Pregnancy. A hormone produced during pregnancy, human chorionic gonadotropin (HCG), may cause your thyroid gland to enlarge slightly.
Inflammation. Thyroiditis is an inflammatory condition that can cause pain and swelling in the thyroid. It may also cause an over- or underproduction of thyroxine.
Iodine deficiency. Iodine, which is essential for the production of thyroid hormones, is found primarily in seawater and in the soil in coastal areas. In the developing world, people who live inland or at high elevations are often iodine deficient and can develop goiters when the thyroid enlarges in an effort to obtain more iodine. The initial iodine deficiency may be made even worse by a diet high in hormone-inhibiting foods, such as cabbage, broccoli and cauliflower.

Although a lack of dietary iodine is the main cause of goiters in many parts of the world, this is not often the case in countries where iodine is routinely added to table salt and other foods.

Symptoms of Goiter

A goitre, correlated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disease. To get hyperthyroidism, the most frequent symptoms are connected with adrenergic stimulation: tachycardia, palpitations, anxiety, tremor, increased blood pressure and heat intolerance. Clinical manifestations tend to be linked to hypermetabolism, (increased metabolism), excess thyroid gland, a rise in oxygen intake, metabolic changes in protein metabolism, immunologic stimulation of diffuse goitre, and ocular changes (exophthalmos). Hypothyroid people could have weight reduction despite bad desire, cold intolerance, migraines and constipation. Nevertheless, these signs tend to be non invasive and make identification difficult.
