Hyperthyroidism

Hyperthyroidism : Women    thyroid   stimulating   antibody  activity  declines during pregnancy   associated  with chemical    remission.  When   mild thyrotoxicosis may be difficult to diagnose   during pregnancy    overt can be easily diagnosed. The  diagnosis   is confirmed when   an abnormally  low thyroid    stimulating hormone level is accompanied by abnormally  high serum  triiodothyronine levels -   . The   major  cause of hyperthyroidism   in pregnancy     is Graves disease an organ specific   autoimmune process   usually associated with   thyroid  stimulating    antibodies. In many  women    thyroid   stimulating   antibody  activity  declines during pregnancy   associated  with chemical    remission.

Pregnancy    outcomes depend  upon   whether    metabolic   control is achieved   .women   who remain hyperthyroid  despite therapy    and in those whose   disease   is  untreated    there is a higher   incidence  of preeclampsia heart failure    and adverse   perinatal outcomes. Thyroid   storm is encountered only  rarely in untreated   women  with Graves disease. Heart  failure is  more common  than T storm cases.
