Maternity blues
Maternity blues, also known as baby blues and postpartum blues, is a transient condition that 75-80% of mothers could experience shortly after childbirth with a wide variety of symptoms which generally involve mood lability, tearfulness, and some mild anxiety and depressive symptoms. Baby blues is not postpartum depression, unless it is abnormally severe.After the placenta is delivered, the placental "hormone factory" shuts down causing radical changes in hormone levels, and the woman can suffer symptoms due to withdrawal from the high pregnancy levels of estrogen, progesterone and endorphins. Combined with this shift in hormone levels is the physical, mental and emotional exhaustion - as well as sleep deprivation typical of parenting a newborn. All of these factors contribute to the condition.
Puerperal disorder
Postpartum depression is a moderate to severe depressive episode starting anytime during pregnancy or within the four weeks following delivery. It occurs in 4-20% of pregnancies, depending on its definition. Without treatment, postpartum depression can last for months or years. In addition to affecting the mother’s health, it can interfere with her ability to connect with and care for her baby and may cause the baby to have problems with sleeping, eating, and behavior as he or she grows. In 38% of the cases of postpartum depression, women are still depressed 3 years postpartum. In 0.2% of pregnancies, postpartum depression leads to postpartum psychosis.
