Overactive thyroid, increased production of thyroid hormone (hyperthyroidism) can be the result of an inflammation of the thyroid gland, a thyroid nodule, excessive iodine intake, overproduction of thyroid-stimulating hormone in the pituitary gland, certain special tumors, excessive intake of thyroid hormones (for example in case of treatment of hypothyroidism) and many other specific diseases. And we have to speak about an autoimmune disease of the thyroid gland, the Graves-Basedow disease which is of high priority.

Symptoms of hyperthyroidism

  • goiter (enlargement of the thyroid gland),
  • rapid heartbeat,
  • eye symptoms (protruding eyeball),

Patients experience enhanced metabolism, faster heartbeat, increased blood pressure, warm and wet skin and they can hardly bear warmth. Hair fall is frequent, the hair becomes brittle and thin. Patients become irritable and mood swings may occur. They may experience difficulty with focusing and sleeping disorders may also develop.
The disease affects the gastrointestinal tract as well. Patients have extremely good appetite however the loose weight. Weight loss can be significant. Due to the enhanced bowel movements, patients pass stool more times daily, even diarrhoea may develop.

Thyroid scintigraphy helps to detect the enlarged and overactive thyroid gland, and with radioiodine therapy all these can be effectively treated.
