low blood pressure (hypotension)

If the thyroid gland produces too few hormones, this is called hypothyroidism. Thyroid hormones are energy suppliers for many body cells, therefore a lack of these hormones slows down the metabolic processes in the body. Possible causes of hypothyroidism are Hashimoto thyroiditis (an autoimmune disease of the thyroid gland), removal of the thyroid gland or radiotherapy, iodine deficiency (needed for the formation of thyroid hormones), medication or drugs. The symptoms are typically rather unspecific and can be more or less pronounced: lack of drive, sleep disturbances, hair loss, constipation, weight gain, tiredness, general physical exhaustion, muscle weakness, depressive mood.
