During pregnancy, hormone levels can be both above and below normal. That is why it is very important to monitor their number. This will provide the mother with confidence that the baby will be born he althy and without various pathologies. During pregnancy, doctors pay special attention to the level of TSH, which regulates the functioning of the thyroid gland.

The pituitary gland, which controls the endocrine system, produces thyroid-stimulating hormone. With the help of these substances, the work of internal organs is regulated. According to a blood test, based on certain TSH indicators, one can judge the course of pregnancy. In this way, specialists can identify hormonal disruptions in a woman's body that can harm a child.

Thyrotropic hormone during pregnancy

This substance affects the quality of the thyroid gland. She, in turn, is responsible formetabolic processes of proteins, carbohydrates and fats, regulates the activity of the reproductive, nervous and cardiac systems, as well as the work of the gastrointestinal tract.

Many do not understand why it is necessary to control the TSH during pregnancy. It is important to know that thyroid hormones stimulate the body of the ovary, the work of which contributes to the normal course of pregnancy.

As a result of increased blood supply, the activity of the thyroid gland increases. TSH during pregnancy (the norm of the 1st trimester, in particular, contains very low levels) should definitely be monitored.

What should be the indicators?

A woman, first of all, should be registered at the clinic, where the gynecologist, after examination, will prescribe the most important tests. Among other things, you must constantly monitor your TSH during pregnancy. The norm (1 trimester) has generally accepted indicators from 0.1 to 2.0 honey / l. At the beginning of pregnancy, the amount of the hormone will differ from subsequent periods, but it should not exceed the specified rate before the onset of labor.

Thyroid Stimulating Hormone Norm Chart

The list indicates how low the TSH is during pregnancy (1st trimester). The table also contains those indicators that should be in all three cycles of gestation. In addition, much will depend on the state of he alth of the woman. At the beginning of pregnancy, you can see a low content of the hormone. But do not worry: such TSH during pregnancy is the norm (1 trimester is most prone to fluctuations in the levelthyroid-stimulating hormone). If the mother already had problems with the thyroid gland before conception, then it is necessary to immediately take tests to determine the level of hormones. During this period, the fetus does not secrete thyroid hormones. There is only one source left - the mother's body. Because of this, an increase in the level of T 3 and a decrease in T 4 can be seen in the mother's blood. Therefore, you need to constantly monitor TSH during pregnancy. The norm of the 1st trimester can be quite low, but this is understandable and not dangerous.

Timing	Normal readings, honey/l
1st trimester	0, 1-2, 0
2 trimester	0, 2-3, 0
3 trimester	0, 3-3, 0

At the second stage of pregnancy, the baby develops a thyroid gland and normalizes the production of hormones. At this time, thyroxine levels decrease, and thyroid-stimulating hormone levels increase. In subsequent trimesters, the level of the hormone becomes higher, but this does not mean that it should exceed the permissible limits.

Small deviations are not capable of harming the mother and fetus, but a significant difference should be a signal that action needs to be taken.

TSH above normal

The hormone during pregnancy can be several times higher than normal, which leads to the development of hypothyroidism. At this point, the thyroid gland reduces its activity and does not synthesize hormones in the required volume. TSH above normal during pregnancy (1st trimester) may signal the presence of a pituitary or thyroid tumor.

It is very important to reduce this level, otherwise the child will not receive the substances necessary for the development of the thyroid gland. All this can lead to an early miscarriage or the occurrence of pathologies.

Symptoms of elevated TSH levels

Elevated levels of thyroid-stimulating hormone can make you feel tired and fatigued. The following signs are also present:

• Pale skin appears.
• Low temperature can be observed.
• May also increase body weight in the complete absence of hunger.
• Insomnia appears.
• Swelling visible.

These symptoms indicate that a woman's body may increase TSH during pregnancy. What it is? The TSH norm can deviate from the generally accepted values, and the listed symptoms are also observed during the normal course of the gestation period. Only a competent doctor can understand these nuances. When TSH is elevated during pregnancy, the causes and symptoms can be very diverse. That is why it is better to play it safe and take blood tests for hormones. Judging by the results of the analysis, the doctor will draw a conclusion and draw up the right treatment plan.

TSH is below normal during pregnancy

There are situations in which this indicator can be not only increased, but also lowered.

Symptoms of low TSH levels are as follows:

• Headaches may occur.
• Blood pressure becomes unstable.
• You can also see an increasetemperature.
• Body weight can be heavily reduced, while appetite, on the contrary, increases.
• There is nervousness and aggression.

In such cases, you can not self-medicate. If you notice any symptoms, you should immediately consult a doctor.

Low hormone levels during pregnancy lead to hyperthyroidism. During this period, the thyroid gland produces a large amount of these substances. Thyroid-stimulating hormone levels decrease due to stress or due to the development of tumors. All this negatively affects the he alth of the pregnant woman and the unborn child. To prevent such consequences, it is necessary to take drugs that suppress the synthesis of thyroid hormones.

Council of experts

Doctors who deal with this problem recommend a certain diet to increase TSH levels during pregnancy. It is necessary to eat protein foods, and fats, carbohydrates and s alts should be limited. Buckwheat, beets, lettuce and sea kale are considered very useful.

What is the danger of elevated thyroid-stimulating hormone during pregnancy?

A very undesirable moment during pregnancy is an increase in the level of thyroid-stimulating hormone, as this leads to abnormal development of the fetus. It is very important to take urgent action because a child can be born with mental and physical problems.

The greatest threat is present at the beginning of pregnancy - during this period, the most important organs of the fetus begin to form. The child perceives hormonalbackground of the mother due to the lack of functions of her own thyroid gland.

A woman with an elevated TSH level may experience various diseases:

• Severe preeclampsia.
• Cholecystectomy and various neoplasms.
• You may notice problems with adrenal activity.
• Elevated hormone levels can lead to mental or somatic disorders.

These are very serious diseases that cause great harm to the body of the mother and child, so it is necessary to pay attention to them in time.

How do I manage high thyroid-stimulating hormone levels?

Treatment should only be started when TSH levels are significantly above normal. If the deviations are small, then nothing can be done. Of course, this decision is made exclusively by the doctor.

This must be monitored from the first trimester. If treatment is started on time, many problems can be avoided.

Drug use

Often use various analogues of "Thyroxin". You may need iodine-containing drugs. These funds are prescribed by the attending physician and are taken, as a rule, for a long time. Start taking a small dose. These drugs cannot be used without a doctor's prescription, as they are selected individually.

Disease prevention

Many are confused when they find out they have elevated TSH levels during pregnancy. Already duringplanning it is necessary to protect yourself from such troubles. To do this, you need to take tests for hormones. If any problem appears, it is urgent to take up treatment

What should I do?

The doctor may advise taking Iodomarin. It is because of the lack of this substance that the level of the hormone is unstable. It is impossible to take hormonal drugs uncontrollably. Specialists can control the process based on the conclusions made only after passing the tests.

It is very important for a pregnant woman to rest more often. During this period, light gymnastic exercises and walks in the fresh air are useful. You can not self-medicate, on the contrary, you must immediately visit a doctor.

Helpful tips

There is an interesting fact that iodine enters the thyroid cells only at the tenth week, and at the fourth month of pregnancy, hormones begin to develop in the fetus. If the described condition progresses in a severe form, then giving birth is prohibited. But there are times when you can independently normalize the activity of the thyroid gland. To do this, you need to introduce iodized s alt into your diet. For a normal pregnancy, you need to follow all the recommendations of doctors and be in a good mood more often.
