How thyroid does effects pregnancy of women?

The Thyroid is a disorder that affects the thyroid gland. Sometimes the body produces too much or too little thyroid hormone this is due to the way the body uses energy and affect nearly every organ in the body. The increase in thyroid hormone is called hyperthyroidism and can cause many of the body’s functions to speed up. Decrease in thyroid hormone is called hypothyroidism can cause many of the body’s functions to slow down. Thyroid hormone plays an important role during pregnancy. It is very important to protect their fetuses from thyroid problems by learning and keeping thyroid function testing with proper medications.

About thyroid

Thyroid is a 2 inch butterfly shaped gland that weights less than 1 ounce. It is located in the front of the neck that is below the larynx, or voice box. It has two lobes, one on either side of the windpipe. It is one of the glands that make up the endocrine system and it can produce, store, and release hormones into the bloodstream. The hormone can travel through the body and direct the activity of the body’s cells.

The thyroid gland’s production of thyroid hormones is Triiodothyronine T3 and Thyroxine T4 is regulated by TSH, which is made by the pituitary gland. Thyroid hormones affect brain development, heart, body temperature, skin dryness, weight, metabolism, breathing, nervous system, muscle strength, menstrual cycles, and cholesterol levels. The pituitary releases more TSH when thyroid hormone levels in the blood are low. The pituitary responds by decreasing TSH production, when thyroid hormone levels are high.

Thyroid function during pregnancy

The two pregnancy hormones that are human chorionic gonadotropin and estrogen can cause increased thyroid hormone levels in the blood. HCG is similar to TSH and mildly stimulates the thyroid to produce more thyroid hormone. The increase in estrogen can produce higher levels of thyroid binding globulin that are known as thyroxine binding globulin, a protein that transports thyroid hormone in the blood. These hormonal changes make thyroid function tests during pregnancy difficult to interpret. Thyroid hormone is critical to normal development of the baby’s brain and nervous system. The fetus depends on the mother’s supply of thyroid hormone, which comes through the placenta during the first trimester. The baby’s thyroid begins to function on its own at around 12 weeks. The thyroid enlarges slightly in healthy women during pregnancy, but not enough to detect by a physical exam. You can notice enlarged thyroid that can be a sign of thyroid disease. This problem can be difficult to diagnose in pregnancy due to higher levels of thyroid hormone in the blood, increased thyroid size, fatigue and other thyroid disorders.

The thyroid gland is a small gland in front of the neck that controls the body’s metabolism.  The thyroid gland produces hormones which regulate how the cells use energy.

Thyroid disease happens when your immune system attacks and destroys cells in the thyroid gland. This results in production of either too many hormones (hyperthyroidism) or in production of too few hormones (hypothyroidism). Some women develop thyroid problems before they become pregnant, while others experience them for the first time during pregnancy.
