Postnatal Mental Health

(Content revised 02/2023)

Importance of postnatal mental health

After delivery, because of the hormonal changes, role change, challenges in baby care and family problems, mothers could have a higher risk of suffering from mood disorders. Postnatal depression could affect mothers' ability in taking care of their baby and have impact on infants' physical health, cognitive development as well as emotional and behavioural development. The partners of mothers with postnatal depression also had higher risk to suffer from emotional disturbance. Thus, it is very important to take care of the mental health of women in the postnatal period.

Postnatal mood problems

There are three main categories of postnatal mood problems: (1) postnatal blues, (2) postnatal depression and (3) postnatal psychosis, each of which differs in its prevalence, clinical presentation, level of severity and management.

(1) Postnatal Blues

  • It affects about 40% - 80% of postnatal women
  • It is a transient state characterized by mood swings, tearfulness, troubled sleeping and irritability. The symptoms usually occur around day 3 to day 5 after childbirth
  • The symptoms are relatively mild and often settle spontaneously within days

(2) Postnatal Depression

  • It affects about 13% - 19% of postnatal women
  • Symptoms are similar to a depressive episode experienced at other times. The onset is usually within 6 weeks but can also occur anytime within a year after childbirth
  • Most of the mothers with postnatal depression recover if they could be identified early and receive proper treatment and support by family

(3) Postnatal Psychosis

  • It affects about 0.1% - 0.5% of postnatal women
  • Prominent features include hearing non-existing voices, bizarre thoughts of being harmed by others and ideas of self-harm or baby-harm. Symptoms usually occur within 14 days after childbirth
  • This is a psychiatric emergency. Urgent referral to a psychiatrist or attending Accident and Emergency Department of hospital is necessary

Early identification of postnatal depression

Major symptoms of postnatal depression include:

  • Persistent period of low mood, such as feeling depressed and sad, crying without reason or wanting to cry but have no tears

  • Disturbance in appetite
  • Sleep problems
  • Fatigue or loss of energy for most of the time
  • Difficult to concentrate or make decision
