The sheep resign from the old year, the monkey to follow the new year. As a rule, the Chinese New Year holiday is often the “birth season”, are you ready to have a monkey baby? In order to have a monkey baby, it is not enough to be psychologically prepared, but also physically well prepared. The first step is to have a physical examination, of which the thyroid function test is indispensable. The thyroid gland is located in the neck, 2-3 cm below the “laryngeal node”, and is shaped like a hoodoo. It is the largest endocrine organ in the body, which synthesizes and secretes thyroid hormones, and its main function is to promote material and energy metabolism, growth and development processes. If this “little butterfly” hidden in your body does not work properly, the consequences can be serious. When the thyroid gland works too hard and secretes too many hormones, you can develop hyperthyroidism (hyperthyroidism for short). Patients with hyperthyroidism are prone to sweating, preferring coolness and fearing heat; they often feel hungry and eat a lot but become thin; they also suffer from elevated blood calcium and osteoporosis due to the accelerated breakdown of protein and bone protein in the body; they suffer from increased excitability of the central nervous system, resulting in poor concentration, moodiness, restlessness, and poor sleep. When the thyroid gland is negatively “idle” and does not produce enough hormones, hypothyroidism (hypothyroidism for short) will develop. Patients with hypothyroidism like heat and hate cold, and are prone to diseases such as edema; memory loss, slow speech and movement due to reduced excitability of the central nervous system. Why is it necessary to check the thyroid gland in preparation for pregnancy? While hyperthyroidism and hypothyroidism can cause illness in the general population, abnormal thyroid function can be “fatal” for pregnant women – because it increases the risk of miscarriage and premature birth. ”One important function of thyroid hormone is to promote the growth and development of nerves, bones, muscles and reproductive organs, and it is one of the hormones necessary for the development of the fetal nervous system.” Since the thyroid hormone needed for fetal development during 12 weeks basically comes from the mother, if the mother does not produce enough thyroid hormone, then naturally the fetus will not get sufficient amount of thyroid hormone either. ”If a pregnant woman has hypothyroidism, then the risk of fetal miscarriage and premature birth is increased. Also, hypothyroidism can affect the normal growth and intellectual development of the fetus, resulting in low intelligence, slow development, and even cretinism.” Pregnant women with hyperthyroidism, on the other hand, may suffer from nutrient deficiencies in the fetus due to hyper-metabolism, which can affect fetal growth and development. In case of moderate or severe hyperthyroidism, the risk of preterm delivery and perinatal death are correspondingly increased. Related tests Thyroid function (five tests): 1. Sensitive indicator for diagnosing hyperthyroidism or hypothyroidism and monitoring the efficacy; 2. Differentiation of certain thyroid diseases from non-thyroid diseases; 3. Evaluation of thyroid function. Thyroid antibodies (three tests): screening for autoimmune thyroid diseases, diagnosis and differentiation of hyperthyroidism, thyroid nodules and subthyroiditis. Thyroid ultrasound (with ultrasound computer graphic report): examines the structure of the thyroid gland and screens for lesions. Color ultrasound has strong discriminatory power and effective identification of the nature of organ lesions.
