Hyperthyroidism is not a separate disease, it is a pathological condition at which there are signs of the body poisoning hormones of the thyroid gland. How signs of hyperthyroidism and what causes this phenomenon.

Hyperthyroidism — is not
some particular disease, this is a state characterized by excessive
production of thyroid hormones, such as triiodothyronine (t3 ) and thyroxine (t4).
The work of the thyroid gland can
violated
The defeat that develops the condition is called primary hyperthyroidism. The causes of hormonal imbalance can
melting in the constriction of the central regulation of the endocrine function, it is known that
The production of hormones in the body is controlled by hypophysis and hypothalamus,
Located in the brain. In this case, hyperthyroidism is called secondary
and tertiary.
Thyroid gland
often called the small conductor of the Big Orchestra. Tiny organ, weighing everything
12-25 g, affects the work of all organs and systems, its excessive activity is negative
affects their functions.
Short-term hyperthyroidism, more often associated with hormone reception
drugs in the treatment of thyroid diseases can pass unnoticed.
With a long-term increase in the level of thyroid hormones, signs of hyperthyroidism are similar
poisoning because it is often called thyredoxycosis.
Hyperthyroidism can be
quite normal condition of the body, raising the level of hormone thyroid
glands, for example, is observed during pregnancy, it is necessary for normal
development of the fetus and its prosperous tooling. Of course, it's not about
increasing the number of hormones at times, but some deviation from
«Nonable» There are norms. Another case of diseases that change the endocrine function
«Shields». What is this
Diseases?
- In 60-80% of cases of hyperthyroidism, cause increase in products
Hormones becomes diffuse toxic goiter (Basedova disease or illness
Graves). Concept «Diffuse» means that the disease affects the fabrics
thyroid gland and not accompanied by the formation of nodes. Originally or
Partially increases, functionally active tissue becomes greater and, as
Corollary, produces unnecessary number of hormones. - Signs
Hyperthyroidism is also observed when
nodal
toxic zob, called toxic adenoma of the thyroid gland or
Plammer's disease. This pathology is found in the elderly and characterized
the formation of a benign tumor of the thyroid gland capable
Alone to produce hormones. - Subacute thyroiditis or thyroidit de cervone at the initial stages
development is often accompanied by hyperthyroidism.
The diagnosis of this state includes repeated blood tests on
Hormones «Shields». - Increase the number of thyroid hormones
may be due to uncontrolled hormone reception
Preparations in the treatment of hypothyroidism.
Endocrine system
the human body is extremely difficult, the mutual influence of those included in it
organs amazing. For example, as the disease of the ovaries may affect
the work of the thyroid gland, because they are located so far and, it would seem, in no way
not connected?
To fairly rare cases of hyperthyroidism include:
- Hyperthyroidism with teratom (tumor) ovarian.
- Iodine-based syndrome, in which hyperproduction
Hormones are caused by the redundant intake of iodine into the body when taking
iodine-containing drugs. - Hyperthyroidism acromegaloid with hypeotosis or
Truell-Jun syndrome associated with a pituitary tumor and the formation of a large
The amount of thyrotropic hormone forcing the thyroid gland to work «with
double strength».
Whatever the hyperthyroidism is caused, the diagnosis is based on the laboratory
biochemical examination of blood, determining the level of triiodothyronine (T3 ), thyroxine (t4 ) and thyrotropic hormone (TSH) pituitary. Additionally for detection
autoimmune thyroiditis and Greiva disease is assigned an analysis of anti-ramp
antibodies. Finding the cause of the thyroid function disorders includes ultrasound
Study and radioisotope scanning, brain study — CT I
MRI.
To date, not
It is quite clear whether people who do not have symptoms of hyperthyroidism should be held
Research on thyroid hormones. According to the recommendations of American
Associations of endocrinologists related to the treatment of thyroid gland, recommended
Once every 5 years, starting from 35 years of age, perform the ultrasound of the thyroid
glands, especially women.
