==Overview==
Postpartum thyroid dysfunction also known as postpartum thyroid dysfunction syndrome, is characterized by abnormal functioning of the [[thyroid gland]] after child birth. Postpartum thyroid dysfunction can either be a pre-existent [[thyroid disease]] that becomes clinically significant during [[postpartum]] duration or it may appear as a new dysfunction. Postpartum thyroid dysfunction may present as [[Grave's disease]], [[Hashimoto's thyroiditis]], [[postpartum thyroiditis]] or [[silent thyroiditis]].

Overview

Postpartum thyroid dysfunction also known as postpartum thyroid dysfunction syndrome, is characterized by abnormal functioning of the thyroid gland after child birth. Postpartum thyroid dysfunction can either be a pre-existing thyroid disease became clinically significant after delivery or it may appear as a newly developed dysfunction. Postpartum thyroid dysfunction may present as Grave's disease, Hashimoto's thyroiditis, postpartum thyroiditis or silent thyroiditis. Postpartum thyroid dysfunction most commonly presents as hyperthyroidism followed by hypothyroidism. In some cases the second phase may proceed to either normal thyroid status or remains hypothyroid. The hyperthyroidism phase may be asymptomatic or patients may experience neuroexcitatory symptoms like palpitations. The hypothyroidism phase is usually symptomatic and may need treatment. Postpartum thyroid dysfunction may also present as exclusive hypothyroidism or hyperthyroidism.

Classification

Postpartum thyroid dysfunction can be classified on the base of presentation and the clinical course of the disease.[1][2][3][4]
