Hyperthyroidism

 

an increase in the function of the thyroid gland. Hyperthyroidism is one of the manifestations of a toxic diffuse goiter. It usually arises as a result of psychic trauma and sometimes with certain diseases and conditions, such as tuberculosis, rheumatism, or pregnancy. More rarely it is the result of an infection. It is manifested by increased excitability of the nervous system, intensification of reflexes, slight psychic agitation, rapid fatigability, acceleration of pulse rate, trembling of the hands, tendency to perspire, increase in basal metabolic rate, and weight loss. Hyperthyroidism is often combined with dysfunctions of other endocrine glands. Treatment for it includes remedies that calm the nervous system and microdoses of iodine.
