Thyroid

What is the thyroid?

The thyroid gland is to be found below the thyroid cartilage or Adam’s apple that is in front of the neck. It is one of the biggest endocrine glands in the body. It is controlled by the anterior pituitary and hypothalamus. The thyroid controls the fast use of energy in the body, controls the body to be aware of other hormones and makes proteins. The thyroid gland produces thyroid hormones that control body metabolism: triiodothyronine (T3 ) and thyroxine (T4). They are the cells that can absorb iodine and synthesized with tyrosine.

 

Thyroid problems

The infection of the thyroid gland can effect in two types: hyperthyroidism and hypothyroidism. Mostly women have all common problems with thyroid hormones than men.

Hyperthyroidism is too much or an overproduction of the thyroid hormones. It is generally caused by Graves’ disease. The disease can cause the growth of a toxic goiter and symptoms of this are bulging eyes (exopthalmos), weight loss, excessive sweating, palpitations, diarrhea, abnormal sensitivity to heat and muscle weakness.

Hypothyroidism is too little or underproduction of thyroid hormone. A fall of hormone production will lead to low level of energy. This disorder may cause autoimmune that is called Hashimoto’s thyroiditis wherein the body attacks thyroid tissues. This is also caused by iodine insufficiency or the removal of the thyroid gland as to treat the hyperthyroidism. People with underactive thyroid may require hormone replacement therapy which is necessary to the life of the patient. Treatment with thyroid hormone should be administered under the care of a doctor and the effect can take a couple of weeks.

 

Both can endanger pregnant women, infants and newborns

In hyperthyroidism, it occurs in about 1 in 2,000 pregnancies and 95% of Graves’ disease is newly diagnosed during pregnancy.  Untreated by this disorder can cause maternal and fetal complications plus tachycardia (abnormally rapid heartbeat) and poor weight gains.

On the other hand, when hypothyroidism undiagnosed by this disorder can increase the possibility of growth of retardation of the fetus or stillbirth. If the newborn and infant lack of thyroid hormones, they can develop dwarfism (stunted growth) and cretinism (mental retardation). It increased also the probability that the pregnant women may suffer from complications of pregnancy such as eclampsia, placental abruption and anemia. A baby of hypothyroidism is unusually quiet and inactive, have a poor appetite and sleep for long period of time.

 

Thyroid Gland Cancer

The thyroid gland cancer is rare and the occurrence is less than 10% of thyroid nodules and it may take several years to determine to be cancerous. Those who acknowledged radiation treatment from the neck to the head earlier in life will have a possible cure for acne be likely to have higher than normal susceptibility for thyroid cancer.

 

Consult a doctor if there are symptoms of hyperthyroidism or hypothyroidism. It is much safer to have a daily visit to a doctor to prevent the symptoms. If positive with this kind of disorder, we should follow the medications and instructions of the physician.
