Postpartum depression is a term to describe a type of depression experienced by mothers who recently gave birth. It is caused by the hormonal changes, adjustment of routine, and fatigue that follows after having a new baby. It affects 1 out of 8 women during the first few months after giving birth. It is very common, but not very well discussed. It is important to know if you or someone you know is experiencing it to provide support and in some cases, medication is required.
