Postpartum Depression: Signs, Causes, and How to Get Help

You Are Not Alone

Postpartum depression (PPD) affects approximately 1 in 5 new mothers. It is one of the most common complications of childbirth — and one of the most under-reported, because shame, fear, and the pressure to appear to be coping keep many women from seeking help.

If you are reading this wondering if what you're experiencing is PPD, that awareness itself is important. Seeking information is the first step towards feeling better.

Baby Blues vs Postpartum Depression vs Postpartum Anxiety

These three conditions are often confused. They exist on a spectrum and can overlap — but they are distinct, and their treatment differs.

Postpartum anxiety is as common as PPD but often unrecognised. Signs include:

• Racing thoughts about catastrophic outcomes ("what if the baby stops breathing?")
• Inability to sleep even when the baby is sleeping
• Constant checking behaviours
• Feeling on-edge or unable to relax
• Physical symptoms: heart racing, chest tightness, dizziness

Many women experience both PPD and postpartum anxiety simultaneously. Both respond to treatment.

Signs and Symptoms of PPD

PPD can present differently for every woman. Common symptoms include:

Mood and emotion:

• Persistent low mood, sadness, or emptiness lasting more than 2 weeks
• Crying frequently without a clear reason
• Feeling numb, disconnected, or like you're watching your life from a distance
• Irritability, anger, or rage that feels out of proportion
• Feeling like a failure as a mother

Thoughts:

• Intrusive thoughts about something bad happening to the baby
• Thoughts that your baby would be better off without you
• Difficulty making simple decisions
• Memory problems and inability to concentrate

Physical:

• Exhaustion beyond what normal newborn sleep deprivation explains
• Appetite changes — eating much more or much less than usual
• Difficulty sleeping even when the baby sleeps

Bonding:

• Feeling little connection to your baby
• Going through the motions of care without emotional engagement
• Fear of being alone with the baby

If you are having thoughts of harming yourself or your baby, please seek help immediately. Call your GP, go to A&E, or call a crisis line (Samaritans: 116 123).

The Edinburgh Postnatal Depression Scale (EPDS)

The EPDS is a 10-question screening tool used by midwives and health visitors at routine postnatal appointments. It asks about mood, anxiety, self-harm thoughts, and how you've been feeling over the past 7 days.

You do not need to wait for a professional to administer it — you can find it online and use it to assess yourself. A score of 10 or above (out of 30) suggests you should speak to your GP or health visitor. A score of 13 or above is associated with a high likelihood of PPD.

The EPDS is a screening tool, not a diagnosis. Your healthcare provider will discuss your score with you in context.

At your 6-week postnatal check, ask your GP to carry out the EPDS if they haven't already — you are entitled to this screening on the NHS.

Postpartum Psychosis: Rare but Serious

Postpartum psychosis is a rare but severe psychiatric emergency affecting approximately 1–2 in 1,000 new mothers. It is not the same as PPD and requires immediate hospitalisation.

Signs develop rapidly — often within the first 2 weeks after birth:

• Confused or disorganised thinking
• Hallucinations (hearing or seeing things that are not there)
• Delusions (fixed false beliefs — sometimes about the baby)
• Extreme mood swings — switching rapidly from euphoria to despair
• Unusual behaviour that is out of character
• Inability to sleep for days

Postpartum psychosis is a medical emergency. Call 999 or go to A&E immediately.

Women with a history of bipolar disorder, a previous episode of postpartum psychosis, or a close family member who experienced it are at higher risk. If this applies to you, discuss a postpartum care plan with your psychiatrist before birth.

Causes and Risk Factors

PPD is caused by a complex combination of biological, psychological, and social factors:

• Hormonal changes: The dramatic drop in oestrogen and progesterone after birth affects brain chemistry
• Sleep deprivation: Profound and cumulative; even a few nights of severely interrupted sleep affects mood significantly
• History of depression or anxiety: The strongest single risk factor — women with a prior episode have a 25–50% chance of PPD
• Difficult birth experience: Birth trauma, emergency procedures, or a birth that was very different from planned
• Breastfeeding difficulties: Adding pressure, pain, and exhaustion to an already demanding period
• Lack of social support: Feeling isolated, unsupported, or without a village
• Relationship difficulties: Stress in partnerships often intensifies postpartum
• Previous pregnancy loss

Having risk factors does not mean you will develop PPD — and having no risk factors doesn't mean you won't. It can happen to anyone.

Getting Help

Start with your GP or health visitor. You can make an appointment specifically to discuss how you are feeling. They will not judge you, and they will not take your baby away. They will help you.

In the UK, ask to be referred to the Maternal Mental Health team or Perinatal Mental Health services — these teams specialise specifically in mental health during pregnancy and the postnatal period and can offer more tailored support than a general mental health team.

Treatment options include:

Talking Therapy

Cognitive Behavioural Therapy (CBT) is highly effective for PPD and is available on the NHS. Interpersonal Therapy (IPT) — which focuses on relationship changes during the transition to parenthood — is also recommended in NICE guidance.

Waiting times for NHS talking therapy vary. You can self-refer to IAPT (Improving Access to Psychological Therapies) online at nhs.uk/mental-health/talking-therapies without going through your GP first.

Medication

Antidepressants are highly effective for moderate to severe PPD. They typically take 2–4 weeks to produce noticeable improvement and 6–8 weeks for full effect.

Medication while breastfeeding: Many antidepressants are compatible with breastfeeding. Sertraline and paroxetine have the most evidence for safety during breastfeeding — transfer to breast milk is very low and no adverse effects have been documented in infants at therapeutic doses. Your doctor will discuss the best option for your individual situation.

The risk of untreated PPD to the mother's wellbeing, bonding, and the baby's development is considered greater than the risk of appropriate antidepressant use while breastfeeding.

Combined Approach

Research consistently shows that therapy combined with medication has better outcomes for moderate to severe PPD than either treatment alone.

The Connection Between Birth Trauma and PPD

An estimated 30% of women describe their birth experience as traumatic. Traumatic birth — including emergency procedures, loss of control, feeling unheard, or complications — is associated with:

• Flashbacks or intrusive memories of the birth
• Hypervigilance and anxiety
• Avoidance of reminders (hospitals, birth-related conversations)
• Difficulty bonding (the birth experience overshadows early parenting)

This is sometimes called Post-Traumatic Stress Disorder (PTSD) rather than PPD, though the two can coexist. EMDR (Eye Movement Desensitisation and Reprocessing) and trauma-focused CBT are the most effective treatments.

If your birth experience was frightening or left you feeling unheard, ask for a birth debrief from your hospital midwifery team. You are entitled to one.

Your Partner's Role

Partners are not passive observers — they play an active role in PPD recognition and recovery.

What partners can do:

• Learn the signs of PPD and actively look for them — many women hide symptoms
• Make the GP appointment and offer to go with her
• Take on more night feeds or infant care to allow more sleep
• Handle household tasks without needing to be asked
• Listen without trying to fix it — "I hear you and I'm here" is often more helpful than problem-solving
• Stay connected — withdrawal increases isolation, which worsens PPD

What to avoid:

• Suggesting she should feel grateful ("but we have a healthy baby")
• Minimising how she feels ("you're just tired")
• Leaving her to reach out for help alone

Partners should also check themselves — paternal PPD affects 1 in 10 new fathers and responds to the same treatments.

Recovery Timeline

What to expect with treatment:

• Weeks 1–2: Medication begins; therapy starts or is scheduled. May not feel better yet — antidepressants take time.
• Weeks 3–6: First signs of improvement — sleep, energy, and mood start to lift slightly.
• Weeks 6–12: More consistent improvement; therapy is producing insight and tools.
• Months 3–6: Returning to a sense of self; bonding with baby improving; able to enjoy moments.
• Months 6–12: Most women with PPD are well within this period with appropriate treatment.

Without treatment, PPD can persist for 1–2 years or longer. Early help leads to faster recovery.

How to Support Someone with PPD

If someone you love is experiencing postpartum depression:

• Listen without judgment — don't try to fix it or dismiss how they feel
• Help with practical tasks without being asked or waiting to be told how
• Gently encourage them to speak to their GP — offer to make the appointment or go with them
• Check in regularly — isolation worsens PPD significantly
• Remind them that they are a good mother and that this will pass
