During the pregnancy, the expectant mothers are pregnant with their babies, and they are also happy to suffer some physiological changes.It is more easy to eat than usual, and it is easy to be hungry, prone to trapped, or nausea and vomiting.These are normal reactions during pregnancy, and pregnant mothers need to worry.
However, if severe fatigue, dry skin, fear of cold, loss of appetite, weight loss increases, you must attract attention. It may be a thyroid dysfunction caused by iodine deficiency in the body.
Iodine is an essential trace element for human synthetic thyroid hormones, and thyroid hormones are important organizations that regulate human growth and development and metabolism.If the thyroid hormone is insufficient, it will cause the patient’s thyroid dysfunction, which will affect the intellectual development of the fetus.Development disorder).Iodine deficiency can even lead to abortion, death, and fetal deformedness of pregnant women.
In addition, hypothyroidism can also cause clinical manifestations such as constipation, muscle stiff pain, hoarse sound, loss of memory, severe hair loss, and slow response.
Some people will say that we will have iodine with iodine and iodine?Yes, many studies have found that most urban people are in normal iodine or excessive iodine, but pregnancy is a special period. The physiological changes in the body include the increase in the increase of HCG (human chorionic gonadotropin) and the acceleration of kidney removal rateThe increase in estrogen leads to an increase in TBG (thyroid poinelline binding globulin) and the needs of fetal hypothyroid hormone, which will increase the lack of iodine in pregnant women.
Objective indicators of thyroid function include the five items of urinary iodine and armor.The normal value of sufficient iodine during pregnancy is 150-249 μg/L, and the urinary iodine <150 μg/L is iodine deficiency, and the urine iodine> 250 μg/L is excessive iodine.When pregnant women are in iodine deficiency, they should supplement iodine appropriately. They can be obtained from kelp, seaweed, yam, celery, spinach, cabbage, eggs, sea fish, shellfish and other iodine -containing foods.
It is worth noting that some studies have found that some women during pregnancy have excessive iodine, and excessive iodine also affects the growth and development of the fetus and the function of the mother’s thyroid gland.Therefore, it should be scientifically and reasonable after checking the objective indicator of urinary iodine.
