Any breach on the part of the thyroid gland is dangerous for both the mother and the fetus.Increased thyroid function may be a variant of the norm (in this case, it is short and passes on their own), and a sign of severe endocrine disease - diffuse toxic goiter.
How does the thyroid gland during pregnancy
The thyroid gland produces hormones (thyroxine and triiodothyronine), which are necessary for the child to correct fetal development, especially they are needed for the formation of brain tissue.
during the first trimester of pregnancy and in the early beginning of the second trimester of the thyroid gland of a woman running in emergency mode, because the need to develop a much thyroid hormone to meet the demand of the woman and the growing baby.En thyroid child laid on the fourth week of pregnancy, and the formation of its ends to about sixteen weeks.After that, the child's thyroid gland begins to produce its own hormones.But still they require a sufficient supply of (high compared to
So from the beginning of pregnancy the thyroid gland works in enhanced mode, and slightly expands.It was seen in ancient Egypt, where married women were instructed to wear thin silk thread on the neck, and if it bursts, it is considered a sign of pregnancy.
Transient hyperthyroidism during pregnancy
hyperthyroidism during pregnancy can be transient (transient) - this is due to the physiological characteristicspregnancy and extends no later sixteenth week of pregnancy.
signs of transient increase in thyroid function can be changeable mood, a small rise in temperature and heat intolerance, a small weight loss in the beginning of pregnancy, sometimes - the heartbeat.All of these symptoms sometimes very difficult to distinguish from the normal beginning of pregnancy.Therefore, if a woman loses weight in the first weeks of pregnancy, it is usually prescribed blood analysis for thyroid hormones.Treatment of transient hyperthyroidism does not require, but the woman must be constantly observed to not allow evidence of diffuse toxic goiter.
Hyperthyroidism on the background of diffuse toxic goiter during pregnancy
Graves' disease develops on the background of autoimmune processes in the body (allergy own tissues).It is a serious illness that requires timely detection and treatment.
signs of diffuse toxic goiter are:
- irritable weakness, persistent conflict, anxiety, self-pity, sleep disturbance Dreams: how to understand our dreams , trembling of the hands;
- heart palpitations (tachycardia) - the pulse of up to one hundred beats per minute or higher, arrythmia (extra heart beats, breaking his rhythm), high blood pressure with a large gap between the systolic (upper) and diastolic (bottom) pressure;
- increased appetite, pain in the upper abdomen, diarrhea;
- gleam in his eyes and the expansion of eye slits.
When these symptoms pregnant women exists prescribe blood analysis for thyroid hormones and thyroid stimulating pituitary hormone (it regulates the secretion of thyroid hormones).In addition, the reason ultrasound of the thyroid gland, and if necessary - needle biopsy - a fence contents of the thyroid gland using a fine needle puncture it.
After final diagnosis treatment is prescribed drugs that suppress thyroid function.If a woman is not treated, complications may occur from both the mother and from the fetus because of the constant toxic effects of excess thyroid hormones Thyroid hormones: mechanism of action and physiological effects .It prematurity, toxemia second half of pregnancy, the various malformations of the newborn and its low weight, the development of hyperthyroidism Hyperthyroidism: increased secretion of thyroid hormone newborn.
Pregnant whose Graves' disease was diagnosed in a timely manner with the appointment of adequate treatment, it can have a child without any deviations.
After birth, thyroid problems may not be over.It is known that during pregnancy a woman causes low immunity.After birth, the immune system is gradually recovering.And the immune cells begin to "direct your pryadok."In some cases, they begin to produce antibodies against their own thyroid tissue that postponing in cancer, inflammatory process cause - autoimmune thyroiditis (AT).A sign of postpartum autoimmune thyroiditis Autoimmune thyroiditis - thyroid disease is increasing, the reduction in the amount of thyroid hormone in the blood.
Approximately half the immune system to cope with this problem and the disease goes away.If the phenomenon of hyper and hypothyroidism in this expression, the following treatment - a suppression of the secretion of the thyroid gland or thyroid hormone replacement therapy.
The thyroid gland has a significant impact on the course of pregnancy.
