Postpartum Depression Causes And Symptoms

5. Hormones

A woman experiences a significant increase of the hormones estrogen and progesterone while she is pregnant. When the baby is born, hormone levels suddenly drop, which may trigger psychological problems such as depression or anxiety. Other hormones produced by the thyroid gland may also rapidly fall, which can lead a woman feeling depressed, tired, and sluggish. The drop in hormones coupled with the demands of a newborn baby may contribute to depression or feelings of being overwhelmed.
