Postpartum Thyroidit: Postpartum Thyroiditis can occur in postpartum women. A low TSH with normal free T4 and T3 levels is consistent with subclinical hyperthyroidism. This problem typically results in symptoms including: fatigue, moodiness, hair loss, decreased milk production, and sometimes swelling at the neck. Talk to your Dr about the diagnosis and if you can be treated.
