Psychological complications

Childbirth can be an intense event and strong emotions, both positive and negative, can be brought to the surface. Abnormal and persistent fear of childbirth is known as tokophobia. The prevalence of fear of childbirth around the world ranges between 4–25%, with 3–7% of pregnant women having clinical fear of childbirth. Although pain may be seen as a self-evident and indisputable fact, in reality pain is only one sensation of childbirth. There are many other sensations such as bliss, joy and satisfaction which can be more powerful than pain. Previous studies have indicated that negative expectations can actually increase sensitivity to pain through the process of nocebo hyperalgesia. While positive expectations can reduce pain through placebo analgesia.

Most new mothers may experience mild feelings of unhappiness and worry after giving birth. Babies require a lot of care, so it is normal for mothers to be worried about, or tired from, providing that care. The feelings, often termed the "baby blues", affect up to 80% of mothers. They are somewhat mild, last a week or two, and usually go away on their own.

Postpartum depression is different from the "baby blues". With postpartum depression, feelings of sadness and anxiety can be extreme and might interfere with a woman's ability to care for herself or her family. Because of the severity of the symptoms, postpartum depression usually requires treatment. The condition, which occurs in nearly 15% of births, may begin shortly before or any time after childbirth, but commonly begins between a week and a month after delivery.

Childbirth-related post-traumatic stress disorder is a psychological disorder that can develop in women who have recently given birth. Causes include issues such as an emergency C-section, preterm labour, inadequate care during labour,lack of social support following childbirth, and others. Examples of symptoms include intrusive symptoms, flashbacks and nightmares, as well as symptoms of avoidance (including amnesia for the whole or parts of the event), problems in developing a mother-child attachment, and others similar to those commonly experienced in posttraumatic stress disorder (PTSD). Many women who are experiencing symptoms of PTSD after childbirth are misdiagnosed with postpartum depression or adjustment disorders. These diagnoses can lead to inadequate treatment.

Postpartum psychosis is a rare psychiatric emergency in which symptoms of high mood and racing thoughts (mania), depression, severe confusion, loss of inhibition, paranoia, hallucinations and delusions set in, beginning suddenly in the first two weeks after childbirth. The symptoms vary and can change quickly. It usually requires hospitalisation. The most severe symptoms last from two to 12 weeks, and recovery takes six months to a year.
