Enlargement of the thyroid gland (goitre/struma)

  • Palpable enlargement of the thyroid gland, with or without nodules
  • Rarely, shortness of breath, hoarseness, sore throat or earache

Insufficient hormone production (hypothyroidism)

  • Fatigue and low blood pressure
  • Skin and hair are dry and rough
  • Weight gain in spite of reduced appetite
  • Constipation
  • Women mostly experience menstrual disorders, while men suffer from erectile dysfunction

Excess hormone production (hyperthyroidism)

  • Restlessness and shaking hands
  • High blood pressure
  • Increased sweating
  • Weight loss in spite of a ravenous appetite

Causes and treatment


  • Autoimmune disorders (Basedow’s disease, Hashimoto's disease)
  • Congenital dysfunctions
  • Side effect of operation or medication
  • Iodine deficiency/excess

Further treatment by your doctor / in hospital

Possible tests
  • Testing of blood hormone levels
  • Ultrasound (sonography) of thyroid gland
  • Other specialised tests (e.g. scintigraphy)
  • Examination of tissue samples under a microscope
Possible therapies
  • Medication
  • Operation (removal of thyroid gland)

What can I do myself?

In Switzerland, table salt has been iodised since 1925 to prevent iodine deficiency.
