It's more than feeling sad
Women experience depression about twice as often as men. Many hormonal factors may contribute to the increased rate of depression in women--particularly such factors as menstrual cycle changes, premenstrual syndrome (PMS), pregnancy, miscarriage, postpartum period, perimenopause, and menopause. Many women also face additional stresses such as responsibilities both at work and home, single parenthood, and caring for children and aging parents.
Many women are also particularly vulnerable after the birth of a baby. The hormonal and physical changes, as well as the added responsibility of a new life, can be factors that lead to postpartum depression in some women. While transient "blues" are common in new mothers, a full-blown depressive episode is not a normal occurrence and requires active intervention. Treatment by a sympathetic health care provider and the family's emotional support for the new mother are prime considerations in aiding her to recover her physical and mental well-being and her ability to care for and enjoy the infant.
