**What is TSH?**
TSH stands for Thyroid Stimulating Hormone. The TSH test measures and shows the amount of this hormone in the blood. The TSH hormone is produced by the pituitary gland in the brain and its task is to warn the thyroid gland to produce the hormones needed by the body. (T3), thyroxine (T4) and calcitonin.. By releasing these three hormones, the thyroid controls various functions of the body, including metabolism and growth.. In general, the TSH test is performed to determine the following:
- Determining the main cause of abnormal thyroid hormone levels
- Screening and diagnosis of hypothyroidism or hyperthyroidism
- Diagnosing the correct functioning of the thyroid gland
###
**normal TSH level**
The normal range of TSH in the blood should be between 0.4 and 4.0 mg international units per liter. In people being treated for thyroid disorders, this value is between 0.5 and 3.3 mg. Abnormal TSH levels include:
1... TSH value higher than normal usually indicates hypothyroidism.... When the thyroid does not produce enough hormones, the pituitary gland tries to stimulate the thyroid gland to produce the hormones needed by the body by secreting TSH... It is worth noting that according to the test results, the doctor may do more tests to confirm and make a final diagnosis... Labs, etc.. But according to the reliable website my.clevelandclinic, in general, it can be Consider the following numbers:
Infants up to 5 days: 0.7 - 15.2 international micro units per milliliter (uIU/mL).... Infants 6-90 days: 0.72-11.0 uIU/mL.... Infants 4-12 months: 0.73-8.35 uIU/mL.. Children 1-07-1 years.... Children 1-0.7-1 years.. 7-11 years: 0.6-4.84 uIU/mL .... 12 people Up to 20 years: 0.51-4.3 uIU/mL.... Adults 21-99 years: 0.27-4.2 uIU/mL....

Especially for people who are pregnant, it is very important to have appropriate levels of TSH and thyroid hormones to ensure the healthy development of their babies. TSH levels fluctuate throughout pregnancy. In general, normal TSH levels during pregnancy include:
1st trimester (9-12 weeks): 0.18 - 2.99 (uIU/mL).... 2nd trimester: 0.11 - 3.98 uIU/mL.... 3rd trimester: 0.48 - 4.71 uIU/mL.... ALWAYS check your lab report.. **normal level of TSH in different people and conditions**
The normal range of TSH depends on the sex, age and medical conditions of people, which can be very different. **Sex:**
In general, thyroid disorders are more common in women than men. In addition, the risk of developing thyroid disorders increases during pregnancy and menopause. **Age:**
With the passage of time and age, the level of TSH in the blood increases.... **Pregnancy:**
TSH level in pregnant women is lower than other people.. It is normal that pregnancy hormones increase the level of some thyroid hormones in the blood.... This is necessary for the development of the brain and nervous system of the fetus.... As a result, the level of TSH in the blood decreases..
Doctors monitor the level of TSH continuously during pregnancy.. - Preeclampsia
- Premature delivery
- Low weight during pregnancy
- Heart failure
**Children and minors:**
TSH levels are highest at birth and gradually decrease as the child grows.. Too much TSH may indicate that the thyroid is not producing enough thyroid hormone.. This condition is called hypothyroidism or hypothyroidism.. Some conditions can also cause hypothyroidism, such as Hashimoto's.. Since thyroid hormone suppresses TSH secretion, too little thyroid hormone can cause hypothyroidism. cause excess TSH to be produced by the pituitary gland.. Pituitary disease, such as a TSH-secreting pituitary adenoma, or rare genetic conditions can result in higher than normal levels of TSH and thyroid hormone.... #### **High TSH Symptoms**
A high level of TSH is usually a sign of hypothyroidism. Symptoms of hypothyroidism include:
- Fatigue
Numbness and tingling in the hands
- Constipation
- Unexplained weight gain
- Depression
- Inability to tolerate cold temperatures
- Decreased interest in sex
- Frequent and heavy menstruation
###
**What are the side effects of low TSH?**
If TSH is too low, the thyroid gland is likely to produce excess thyroid hormone. This condition is called hyperthyroidism or hyperthyroidism. It should be noted that various conditions, including Graves' disease and thyroid nodules, lead to hyperthyroidism. A non-functioning pituitary adenoma can lead to low TSH levels as well as low thyroid hormone levels. #### **Symptoms of Low TSH**
A low TSH level is usually a sign of hyperthyroidism. Symptoms of hyperthyroidism include:
- fast heartbeat (palpitations)
- Feeling shaky and/or anxious
- Unreasonable weight loss with increased appetite
- Diarrhea
- Vision changes and/or eye protrusion
- swelling and enlargement of the neck due to enlargement of the thyroid gland (goiter)
- Irregular menstrual periods
