Hyperthyroidism : when too much work - bad

Hyperthyroidism - is the work of the thyroid gland in emergency mode and, consequently, its production of too many hormones that greatly boosts the intensity of metabolic processes and leads to their violations, and further - to the malfunction of organs and systems of the whole organism.

The thyroid gland produces the hormones thyroxine, triiodothyronine and calcitonin.It is important that this hormone is produced no more and no less than necessary because they have a surplus and lack of harmful consequences for the body.For the balance sheet as follows hypothalamus and pituitary gland, but sometimes the chain fails, then the amount of thyroid hormones can get out of control.

Causes of hyperthyroidism

  • Benign nodular tumors.
  • Autoimmune processes when the immune system starts to work against the body (thyroiditis).
  • a lot of stress, psychological trauma.

Lack of iodine in the diet leads to the so-called endemic goiter - a compensatory increase in thyroid when staying in food areas, the poor in iodine.

When raising the level of TSH forgivable

This also happens that a temporary increase in the level of TSH (thyroid stimulating hormone) caused by, for example, the state of pregnancy, adolescence, taking certain birth control contraceptives.This increase is considered to be physiological and usually does not last long.

Treatment

hyperthyroidism

doctors on the patient's condition is selected or pharmacological treatment (tireostatikami-drugs) or surgical (removal of the breast tissue) or a decrease in function of the gland of radioactive iodine radioisotopes.
