It is not known.
Diagnosis and treatment
Diagnosis
The elaboration of the diagnosis implies:
complete a physical and historical examination
analysis of blood with the purpose of verifying the tiroideas hormone level in the blood and other levels of hormones associated to the case
studies of radioactive iodine absorption (I131) - gammagrafía tiroidea- in some occasions, to measure the activity and contours of the thyroid)
Treatment
The suitable treatment will as large as depend the goiter, the causes, the age of the patient and another series of factors.
The surgery to extirpate part of the thyroid (tiroidectomía) is advisable in some patients.
Medication
The medication controls the problem in most of the patients. It includes:
Iodine, to restrain the activity of the gland.
Antitiroideos agents, to reduce the activity of the thyroid.
Propiltiuracil, metimazol and blocking beta adrenérgicos for a symptomatic alivo, mainly in cardiovascular repercussions (palpitaciones, tremors, perspiration...).
This treatment stays normally during at least 1 year. The relapses in these cases when interrupting are frequent the treatment.
The radioactive iodine, that destroys of selective form the tiroidea gland, is used in patients which they have surpassed the fertile age, by its possible effects on the descendants.
Causes
Disorder autoinmune (the body develops antibodies that stimulates the excessive production of the tiroidea hormone).
Tiroideos tumors or nodules.
Tiroiditis (inflammation of the tiroidea gland).
Signs and symptoms
Continuous sensation of calidez or heat.
Tremors.
