Overview

There is no established system for the classification of PPT but it may be classified according to clinical course into three groups: Transient hyperthyroidism, Classic Triphasic, and Transient/ Permanent hypothyroidism.

Classification

• PPT may be classified according to clinical course into three groups:
  • Transient hyperthyroidism: It occurs in 20-30% of cases, in which patient has symptoms of hyperthyroidism and increased levels of T3 and T4 appearing around second postpartum months and stays about two months and retains normal levels at eighth postpartum month.
  • Classic Triphasic :It occurs in 25-40% of cases, in which patient has symptoms of hyperthyroidism and increased levels of T3 and T4 appearing around second postpartum months and stays about two months followed by hypothyroidism and then retains normal levels at eighth postpartum month.
  • Transient / Permanent hypothyroidism: It occurs in 40% of cases, in which patient has symptoms of hypothyroidism and decreased levels of T3 and T4 appearing around second postpartum months and stays about two months and retains normal levels at eighth postpartum month. But some of the cases remain hypothyroid for life long.
