Additional Causes of hypothyroidism include:

Radiation therapy is the neck area – Treating particular cancers such s lymphoma will require to the neck. Radiation damages the cells in the thyroid. This makes it harder for the gland to produce hormones.

Radioactive Iodine treatment – This treatment is often prescribed to people who have an overactive thyroid gland, a condition known as hyperthyroidism. Although radiation eliminates the cells in the thyroid gland, This usually leads to hypothyroidism.

Taking particular medications – Some medications to treat heart problems or psychiatric condition and can occasionally affect the production of thyroid hormone. These can include amiodarone (Cordarone), lithium, interferon alpha and interleukin-2.

Thyroid Surgery to remove the thyroid will lead to hypothyroidism, If you only part of the thyroid is removed, the reaming gland may still be able to generate enough hormone necessary for body to operate.

Too small amount of Iodine in the diet. The thyroid requires Iodine to produce thyroid hormone.

Women with this condition normally have a severe increase in thyroid hormone levels followed by a sharp in thyroid hormone production. Most with postpartum thyroiditis will regain their normal thyroid function.

Problems with the thyroid at birth – Some babies may be bone with a thyroid gland that not develop correctly or does not work properly. This type of hypothyroidism is called congenital hypothyroidism. Most hospitals in the U.S screen babies at birth for this disease

Pituitary gland rarely, a problem with the pituitary gland can conflict with the growth of thyroid home. The pituitary gland makes a hormone, called thyroid stimulating hormone (TSH), which tell s your thyroid how much hormone it should make and release.

Disorder of the hypothalamus- An extremely rare form of hypothyroidism can occur if the hypothalamus in the brain does do not create enough of the TRH hormone. TRH affects the release of TSH from the Pituitary gland.

Hypothyroidism 2Primary hypothyroidism is produced by problems with the thyroid gland itself.
Secondary hypothyroidism occurs when another problem interferes with the thyroid’s ability to produce forms. For example, the pituitary gland and hypothalamus produce hormones that trigger the release of thyroid hormone. A problem with one the glands can make your thyroid underactive.

On occasions un underactive thyroid that results from a problem with the hypothyroid is called
