Doctors recommend that in the absence of complaints to examine the thyroid gland once a year.
If the patient is found endocrinological disease, the doctor may prescribe periodic examinations.
How is thyroid
Preventive examination of the thyroid glandrecommended held twice a year. During the examination the doctor-endocrinologist investigates the structure and evaluates the function of the body. thyroid structure is investigated using palpation. This method can evaluate the prostate volume, density and structure of its tissue, the presence or absence of nodes, etc. If you suspect a pathology of the patient additionally prescribe ultrasound. With the help of the gland structure is checked more accurately determined by its volume. Norm is the volume to 18 ml breast in women and up to 25 ml in males.
The normal thyroid gland increases in volumeadolescents, women in pregnancy and menopause. Ultrasound can detect the nodes to determine their size, to evaluate the echogenicity, contours, detect the presence of liquid. This diagnostic method is absolutely safe, when it is not carrying out the irradiation, it can be carried out even in pregnant women. To perform ultrasound schitvidnoy glands do not require special training. For the study of the body structure is also used CT, it allows for better examination. Generally, a CT scan is prescribed in cases of extensive malignancy, prior to surgery on the gland.
Thyroid ultrasound can further explore the bloodstream, to examine lymph nodes in the neck.
The study of thyroid function
To evaluate the performance of the thyroid gland, appointa blood test for hormones. To do this, the patient must donate blood from a vein (an empty stomach). In the first stage of the study check the level of thyroid stimulating hormone (TSH), carried out with the help of regulation of thyroid function. If TTG would be within the normal range, meaning that the body produces thyroid hormones amount as much as needed. When hormone levels higher than normal may be suspect low thyroid function. TSH less than normal indicates too high, the functional activity of the thyroid gland. Upon receipt of the result is less than or greater than normal values need to conduct additional studies of thyroid hormones - triiodothyronine (T3) and thyroxine (T4).
In the process of diagnostics and spendantibody levels to study the structural components of thyroid cells. Elevated levels of antibodies is a sign of a serious disease - diffuse toxic goiter.
If T4 levels change, and T3 would be normal,in any case it suggests hormonal disorders. If the level of both hormones is too high, it means increased work of the thyroid gland (hyperthyroidism). If T4 levels below normal prostate function is reduced, a condition called hypothyroidism. According to the results of diagnosis and when indicated the doctor prescribes the appropriate treatment and resolves the question of how often the patient will need to take thyroid.
