Antenatal and Postnatal Mental Health

(Content revised 12/2019)

Importance of antenatal and postnatal mental health

Emotional problems during the antenatal or postnatal period would affect mothers' mental state, daily functioning, work performance, marital relationship and baby's development.

During pregnancy, mothers suffering from depression could have a higher risk of miscarriage and premature delivery. Research findings suggested that when mothers had depressive or anxiety symptoms during their pregnancy, they would have a much higher risk of having postnatal depression and their infants showed more difficulties in emotion regulation and behavioural control.

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 may also have a higher risk of emotional disturbance. Thus, it is very important to take care of the mental health of women during the antenatal and postnatal periods.

Emotional disturbances can happen in antenatal period

Getting pregnant brings a lot of excitement to the family. Yet it should not be overlooked that mothers could have different emotions during pregnancy, which include anxiety, helplessness and irritability, etc. Pregnant women could experience a lot of physical changes and discomfort. Their lifestyle may have to be adjusted. Their emotions, therefore, could be affected. Pregnant women could also have a lot of worries about the foetal development or the childcare arrangement after delivery.

Research findings suggested that some factors were related to antenatal anxiety and depression, such as self-esteem of the mother, her marital relationship, in-law relationship and social support. To maintain emotional health during pregnancy, mothers should learn to appreciate themselves, particularly their effort paid in coping with the demands and to accept the limitations during pregnancy. They could also talk to other mothers to bolster social support, or talk to someone they trust to relieve their distress. If the emotional disturbance persists, mothers should seek professional help as early as possible.

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 will recover if they are identified early and receive proper treatment and support from the 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 harming the baby. 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
  • Loss of interest in almost all activities (even lose interest in her child)
  • Disturbance in appetite
  • Sleep problems
  • Fatigue or loss of energy for most of the time
  • Difficult to concentrate or make decisions
  • Feeling guilty, worthlessness and hopelessness

Should the above symptoms persist for 2 weeks or more and have significantly affected the woman's daily functioning, seek professional help as soon as possible.
