Why does childbirth cause mood disorders?
Before we talk about postpartum depression or the baby blues, it helps to understand why childbirth can trigger mood disorders—because the reasons aren’t always obvious at first.
Childbirth—especially with a first baby—can be a major physical and emotional event in a woman’s life. In some cases, it can also be intense or even negative, depending on how difficult the birth experience is.
Giving birth can be traumatic, but even when it isn’t, many changes can affect a first-time mother immediately after delivery:
- Hormonal changes: After delivery, estrogen and progesterone levels drop rapidly, which can affect brain chemistry and mood regulation.
- Lack of sleep: Newborn care often leads to highly interrupted sleep, which is a known trigger for anxiety, irritability, and depression.
- Stress and responsibility: Caring for a newborn is no small task and can feel overwhelming—especially for first-time parents. This emotional strain can take a toll on mental health.
- Previous mental health conditions: With all that maternity involves, women with a history of depression, anxiety, or other mood disorders may be at higher risk of developing postpartum depression.
- Physical recovery: Childbirth is strenuous and can be distressing and painful. Recovery can be physically and emotionally exhausting, and mood changes may be triggered by pain or lingering discomfort after labour or a caesarean delivery.
- Social and emotional factors: Childbirth is a time when many women need strong support from family and friends. Feeling unsupported can have serious negative consequences.
What is postpartum depression and what are its signs?
Postpartum depression is a serious mood disorder that can affect women after giving birth. While it’s normal to experience emotional ups and downs during this period, postpartum depression goes beyond typical exhaustion or stress.
It can interfere with a mother’s ability to care for herself and her baby, and it often requires professional support.
Common signs of postpartum depression include:
- Persistent sadness, hopelessness, or emptiness
- Excessive crying
- Difficulty bonding with the baby
- Loss of interest in activities once enjoyed
- Changes in appetite or sleep (too much or too little)
- Irritability or anger
- Severe anxiety or panic attacks
- Feelings of guilt, worthlessness, or shame
- Thoughts of harming oneself or the baby
These symptoms can appear within the first few weeks after delivery, but may also develop later, up to a year after childbirth.
What is “baby blues” and what are its signs?
In contrast, the “baby blues” are a very real and common—but temporary—emotional state that affects many new mothers in the first few days after childbirth.
Unlike postpartum depression, the baby blues are short-lived and usually resolve without medical intervention once hormonal, physical, and emotional factors begin to stabilise.
Signs of baby blues include:
- Mood swings
- Feeling overwhelmed
- Irritability or frustration
- Trouble sleeping despite feeling tired
- Mild anxiety
- Crying for no clear reason
These symptoms typically begin two to three days after delivery and may last for up to two weeks. They are linked to hormonal changes, sleep deprivation, and the adjustment to life with a newborn.
How to differentiate postpartum depression from “baby blues”
Postpartum depression and baby blues can share some emotional symptoms, so at first it may be difficult to tell them apart. However, there are important differences you can look for:
The baby blues involve mild, short-term emotional changes. They are considered a normal response to the hormonal shifts and physical exhaustion that can follow childbirth. Most women with baby blues can still care for their baby and themselves, even if they feel more emotional than usual.
In contrast, postpartum depression is more intense, lasts longer, and can significantly affect daily life. Symptoms may begin within the first few weeks after delivery—or several months later.
Crucially, postpartum depression doesn’t usually go away on its own. It can make it difficult for a mother to bond with her baby or manage everyday tasks.
One key sign that it may be more than the baby blues is how long symptoms last. If emotional struggles persist for more than two weeks, or if feelings of sadness, anxiety, or hopelessness become overwhelming, it’s important to seek help.
What to do in case of postpartum depression?
If you or someone you know is showing signs of postpartum depression, getting support early can make a significant difference to recovery. Here are some recommendations:
- Talk to a healthcare provider: A doctor, midwife, or mental health professional can assess symptoms and recommend the most appropriate treatment.
- Seek emotional support: Talk to a partner, family member, or friend. Feeling less alone can be an important first step in healing.
- Join a support group: Sharing experiences with other mothers who are facing similar challenges can be deeply reassuring.
- Prioritise rest and nutrition: While it’s not always easy, sleep, balanced meals, and asking for help with baby care matter. In some cases, poor sleep can be a significant part of the problem.
- Consider therapy or medication: Psychotherapy, counselling, and (in some cases) antidepressants can be effective in treating postpartum depression.
Always remember: postpartum depression is not a sign of weakness or failure. It’s a medical condition, and it can be treated. With the right support, mothers can recover and step into their new role with confidence and joy.
Coping with baby blues
Once your little one has arrived, it’s easy to forget about you—but a happy mum means a happy baby. Here are a few things you can do to help ensure baby blues (or postnatal anxiety) doesn’t get the best of you.
- Talk to friends and family if you think you have baby blues. Many women experience symptoms immediately after childbirth. It can be caused by the sudden change in hormones after delivery, combined with stress, isolation, sleep deprivation, and fatigue. You might feel more tearful, overwhelmed, and emotionally fragile.
- The baby blues are perfectly normal, but if your symptoms don’t go away after a few weeks or get worse, you may be suffering from postpartum depression.
- Chat to other new parents. They may be going through something similar.
- Try a postnatal group or mom’s group to meet parents in the same boat.
- Try baby-feeding cafes for a safe space.
- Try baby activity classes or apps like MUSH (if it’s available in your country) to meet new parent friends.
- Try apps like Calm or other mediation and mindfulness apps.
- Consider talking to a professional, there are people who can help. Ask your healthcare provider where to start.
- Get active. It’s surprising what a bit of exercise can do for your mood.
- Eat a healthy, varied and balanced diet.
- As well as trying to get some sun consider a daily supplement containing 10mcg of Vitamin D.
- Try to make time for the simple things like showering and doing your hair—they can really make a big difference.
- Write a mood diary. Noting how you feel each day can help you realize what makes you happy and what doesn’t.
- Be kinder to yourself. You’re doing your best—it doesn’t have to be perfect.
- Ask friends and family to help. A few less errands on your to do list can make all the difference.
Wondering how to know if you have postnatal depression? You’ve just birthed a human, your whole world has been turned upside down, and you haven’t slept for what feels like an age.
That’s enough to make anyone question how they’re coping. But when does a spot of baby blues become postpartum depression?
The Edinburgh Postnatal Depression Scale is a postnatal depression quiz developed by experts to help identify signs of baby blues vs postpartum depression. Baby blues may be caused by hormonal changes in the first week or so after giving birth.
Postpartum depression after having a baby often occurs in the weeks and months that follow, and it can develop up to a year after birth. Answer the questions below to start a conversation about how you’re feeling.
The quiz is designed for use between 6–8 weeks postpartum; select the answer that best describes how you’ve felt over the past seven days (not just today). It is strongly recommended that you complete the quiz with your healthcare provider (HCP).
