Background:
Thyroid dysfunctionin the postpartum period may be related to iodine deficiency, have an immunological basis or may follow thyroiditis. We investigated thyroid dysfunction in a community with a low dietary intake of iodine to assess its prevalence and modes of presentation.
Methods:
One hundred women attending the postnatal clinic of the All India Institute of Medical Sciences, from Delhi and its surrounding areas, were screened for post-partum thyroid dysfunction with triiodothyronine, tetraiodo-thyronine and thyroid stimulating hormone estimation at one, three and six months after parturition.
Results:
Thirteen women developed hypothyroidism after parturition. One of them recovered by the sixth month. There was no demonstrable thyrotoxic phase in any of these patients.
Conclusions:
Postpartum thyroid dysfunction presents solely as hypothyroidism in our patients and may be related to their low dietary intake.
