Other types of thyroid can cause harmless swelling, goiter and thyroid cancer. If you ever experience any of the above symptoms, the chances are high that you are at the risk of thyroid diseases.
Reasons behind the thyroid diseases
Thyroid diseases sometimes result of inappropriate TSH level and it can cause by thyroid gland itself. When the thyroid does not produce enough hormones, then the chemical reactions in your body can get upset. The thyroid disorder can occur due to several disorders like autoimmune diseases, radiation therapy, thyroid surgery, treatment of hyperthyroidism, lack of iodine and certain medications.
Autoimmune diseases -:
Autoimmune diseases occur when your immune system produces antibodies that attack your own tissues. It may happen because of genetic flaw or when virus and bacteria may trigger the response. Most likely, autoimmune disorder is not a result of one factor as it includes more than one factor. It affects the body’s thyroid ability to produce hormones.
Treatment for hyperthyroidism -:
Radioactive iodine and anti-thyroid medications are very effective to stimulate thyroid functions. However, in some cases treatment of hyperthyroidism can result in permanent hyperthyroidism.
A number of medications available for the treatment of thyroid disorders. One such medication is lithium which can have some side effects on your thyroid gland. You should consult your doctor before you start to take this medicine.
Radiation therapy -:
You might know that radiation therapy is used in the treatment of many cancer diseases, but this can lead adverse effects to your thyroid gland and cause hyperthyroidism.
Thyroid surgery -: Removing all or large portions of your thyroid glands can diminish or halt your hormones production. In that case, you need to take thyroid hormones for life.
Iodine deficiency -:
Iodine is found in seaweeds, seafood and the plants grow in iodine-rich soil. It is very essential for the production of hormones only if you take it in the smaller amount, but taking too much iodine can cause hyperthyroidism.
Congenital diseases -: Some babies are born with defective thyroid gland or without the thyroid gland. In some cases, the thyroid gland does not develop for unknown reasons and in some children, it is in the form of the hereditary disorder.
During pregnancy and after pregnancy some women develop hyperthyroidism because they produce antibodies against their own thyroid gland. Hyperthyroidism can increase the risk of premature delivery or even miscarriage in some cases.
