Postnatal Depression: Signs, Causes & Where to Get Help in the UK

Bringing a baby home is supposed to be one of the happiest times of your life. When it doesn't feel that way, when you feel low, anxious, detached, or like you're just going through the motions, something is very wrong — but it's not your fault, and it's not permanent.

Postnatal depression (PND) affects approximately 1 in 5 new mothers and 1 in 10 new fathers and partners in the UK. It is the most common complication of childbirth. And yet it's still vastly under-reported, under-discussed, and under-treated.

Baby blues vs postnatal depression

Baby blues are completely normal and affect up to 80% of new mothers. They typically start around day 2–4 after birth and last a few days. Symptoms include tearfulness, emotional sensitivity, mood swings, and feeling overwhelmed. Baby blues resolve on their own and don't require treatment.

Postnatal depression is different in key ways:

Starts later (usually weeks 1–3 after birth, sometimes up to a year)
Lasts longer (weeks to months without treatment)
More severe and disabling
Requires professional support

Symptoms of postnatal depression

PND doesn't always look like crying. Symptoms vary widely and can include:

Emotional symptoms:

Persistent low mood or hopelessness
Feeling empty, numb, or "flat"
Tearfulness that doesn't lift
Irritability, anger, or rage (particularly common but often overlooked)
Anxiety, worry, or panic attacks
Feeling disconnected from your baby or unable to bond
Feeling like a bad parent, or like your baby would be better off without you

Physical symptoms:

Exhaustion beyond what's explained by broken sleep
Changes in appetite — eating too much or too little
Physical symptoms with no medical cause (headaches, chest tightness)

Behavioural symptoms:

Withdrawing from family and friends
Unable to enjoy things that used to bring pleasure
Struggling to get through daily tasks
Intrusive thoughts about harm (to self or baby)

Postnatal anxiety

Many people with PND also experience significant anxiety — or have anxiety without the classic depression symptoms. This can present as:

Constant worrying about baby's health or safety
Intrusive thoughts ("what if I drop the baby," "what if they stop breathing")
Checking behaviours — checking breathing obsessively, unable to leave baby
Panic attacks

These are symptoms of a treatable condition, not signs that you're a bad parent or that something is wrong with you.

What causes postnatal depression?

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

Biological: Dramatic hormonal changes after birth (oestrogen and progesterone drop sharply), sleep deprivation, thyroid changes, physical recovery from birth.

Psychological: History of depression or anxiety, previous trauma, perfectionism or high expectations of parenting.

Social: Lack of support, relationship difficulties, financial stress, isolation, difficult birth experience, baby health issues.

There is no single cause, and nothing you did (or didn't do) caused it.

PND in fathers and partners

Paternal postnatal depression is real, common, and significantly under-recognised. Fathers often experience different symptoms — irritability, anger, overworking as a way to escape, substance use — that don't fit the classic "depression" narrative. If you're a father or partner and recognise these patterns, you deserve support too.

What to do

1. Tell someone

This is the hardest step. Tell your partner, a friend, your GP, or your health visitor. The EPDS (Edinburgh Postnatal Depression Scale) — a short questionnaire — is routinely offered by health visitors at the 6-week check. Answer it honestly.

2. See your GP

Your GP can:

Confirm the diagnosis
Offer talking therapies (CBT, counselling) — free on the NHS, though there may be a wait
Prescribe antidepressants if appropriate — several are safe while breastfeeding
Refer to specialist perinatal mental health services for more complex cases

Antidepressants are not a last resort. They are an effective, evidence-based treatment and several are considered safe during breastfeeding.

3. NHS talking therapies (IAPT)

You can refer yourself directly to NHS talking therapies without going through your GP at nhs.uk/mental-health/talking-therapies-medicine-treatments. Waiting times vary.

4. Support lines and organisations

PANDAS Foundation: 0808 1961 776 (free, open 11am–10pm)
Association for Postnatal Illness: apni.org — phone support and network of volunteers who've been through PND
Mind: mind.org.uk
Samaritans: 116 123 (available 24/7)

5. Peer support

Meeting other parents who have or are experiencing PND is powerful. Ask your health visitor about local groups, or look at the PANDAS and NCT networks.

If you're having thoughts of harming yourself or your baby

Please tell your GP or health visitor immediately. These thoughts are a symptom of PND — they don't mean you're dangerous or will act on them. But they need immediate professional attention.

If you feel unsafe right now:

Call 999 or go to A&E
Call Samaritans: 116 123
Go to a trusted person

Recovery

With the right support, PND is treatable and the vast majority of people make a full recovery. It may take weeks or months, but it does get better. Many parents say that getting through PND and out the other side made their relationship with their baby deeper and richer than they ever expected.

You are not a bad parent. You have an illness. You deserve care.
