What is postpartum depression?

Postpartum depression is a depression that occurs after a mother gives birth to her child. In this case it is believed that the changes in hormones experienced after birth, which affects the chemistry in the brain resulting in changes in one's moods and/or emotions, is the main cause.

Postpartum depression may start at any point within the first year after giving birth. It may include symptoms such as thoughts of harming your baby, thoughts of causing harm to yourself, or not caring about your baby. If you are experiencing any of these or other signs of depression please contact your physician so that you may be treated.
