What is a thyroid gland?
Thyroid gland is an endocrine gland which is a butterfly shaped gland in front of your neck just above your collarbone. The thyroid gland secretes two hormones, – thyroxin [t4] and tri iodothyronine [t3] hormone. These hormones are necessary for all the cells in your body to work normally; in other word, it regulates the metabolism of your body cells.
Thyroid disorders are very common and tend to occur mainly in women. Although anybody of any age can be affected.
Hypothyroidism is characterized by abnormally low thyroid hormone production by the thyroid gland. There are many disorders those are associated with hypothyroidism. Thyroid hormone affects growth, development and many cellular processes, inadequate hormone has widespread consequences for the body.
Causes of hypothyroidism:
1. Genetic reasons: You are prone to develop hypothyroidism, if you have close family member with an auto immune disease or suffering from some thyroid disorders.
2. Age: Growing age can be another reason to develop hypothyroidism.
3. Auto immune disease: The most common cause of hypothyroidism is Hashimotos‘s thyroiditis. It is an inflammation of thyroid gland. This is an autoimmune disorder.
4. Treatment for hyperthyroidism: Any treatment is given to the people who have overactive thyroid gland.
5. Iodine deficiency: The thyroid gland needs iodine to produce thyroid hormone. As our body does not make it, we need to take it in our diet. Iodized table salt is rich in iodine.
6. Use of certain medication to treat heart problems, cancer, and psychiatric disease can affect thyroid hormone production.
7. Thyroid removal surgery can cause hypothyroidism.
8. Radiation therapy to neck area in certain cancers may damage thyroid cells, which is responsible for poor thyroid hormone production.
9. Pregnancy: Some women can develop hypothyroidism during or after pregnancy. This can lead to miscarriage or high blood pressure in early months of pregnancy if neglected.
