Causes of Hypothyroidism & Hipotirodisme

Hypothyroidism is a condition where the thyroid gland is underactive and produces too little thyroid hormone. Severe hypothyroidism is called miksedema.Penyebab are most commonly found is thyroiditis

Hashimoto. In Hashimoto's thyroiditis, the thyroid gland is often enlarged, and hypothyroidism occurred several months later by the destruction of the gland is still functioning. The second is the commonest cause of treatment of hyperthyroidism.

Either radioactive iodine or surgery tends to cause hypothyroidism. Long-term iodine deficiency in the food, causing enlargement underactive thyroid gland (hypothyroidism goitrosa). Long-term iodine deficiency is a common cause of hypothyroidism in underdeveloped countries.

Here are some causes of Hipotirodisme:

1. Autoimmune diseases. In this condition, the body attacks the thyroid gland due to him as foreign cells eventually die selsel in the thyroid gland and can not produce thyroid hormone. The cause is unknown, but descended in the family and often associated with other autoimmune diseases such as type 1 diabetes, lupus or Sjögren's syndrome.

2. Thyroid tissue loss. Usually occurs secondary to irradiation (radiation) or thyroid gland surgery is performed as a treatment for hyperthyroidism.

3. Kogenital abnormalities, namely infant who was born without a thyroid gland or thyroid gland does not function normally. Consumption of medicines, for example, lithium is often used for the treatment of mood disorders.

While hyperthyroidism is a condition where the thyroid gland to work excessively, resulting in a large number of thyroid hormone.

Hyperthyroidism can be found in the form of Graves' disease, toxic goiter or hyperthyroidism noduler secondary.

The cause of hyperthyroidism:

1. Grave illness, which is an autoimmune disease. The body attacks the thyroid gland cells but instead turn off the cell, what happens is that it appears antibodies stimulate the thyroid gland to produce excessive hormones. One of its characteristics is the protruding eyeball.

2. Adenoma (tumor gland), thyroid toxicity, which occurs when part of the thyroid gland produces thyroid hormone itself without stimulated by thyroid stimulating hormone (TSH). This is usually experienced by patients with goiter (enlarged thyroid gland) long term, especially the elderly.

3. Thyroiditis, is an inflammation of the thyroid gland that cause excessive hormone production. This inflammation can cause the hyperthyroidism that lasts for several weeks.

5. Adenoma (tumor gland) in the form of pituitary tumors in the pituitary gland that causes excess production of TSH that stimulate the thyroid gland to produce thyroid hormones become too excessive.
