Understanding the Postpartum Hormone Crash

Bringing a new baby into the world is a life-changing experience, filled with immense joy and profound challenges. While much attention is rightly given to pregnancy and childbirth, the period immediately after birth, often marked by what’s known as the postpartum hormone crash, can be incredibly demanding for new mothers. Many mums find themselves feeling unexpectedly sweaty, utterly exhausted, and emotionally overwhelmed. Pharmacist Zeinab Ardeshir from PillSorted sheds light on the fascinating biological processes behind labour and the significant hormonal shifts that occur post-delivery, helping us understand these common, yet often unspoken, experiences.

The Three Stages of Labour

Labour is a complex and coordinated biological process designed to bring a baby into the world. It’s not a simple on-and-off switch but a gradual progression through three distinct stages:

• The Latent Phase (Early Labour): This is when contractions begin to build up. Signs that real labour is starting include the “show” (a jelly-like mucus plug coming undone) and your waters breaking. It’s important to distinguish these from Braxton Hicks contractions, which are essentially “practice” contractions that can often be relieved by resting or a warm bath. Real labour contractions become stronger, more regular, and closer together. If you’re ever unsure, always contact your midwife or doctor for advice.
• The Second Stage (Pushing and Birth): After the cervix has fully dilated, contractions intensify and become longer and closer. This is the pushing stage, culminating in the birth of your baby. During this intense period, the support of healthcare professionals is vital to guide you through each step.
• The Last Phase (Delivery of the Placenta): After your baby is born, the final stage involves the delivery of the placenta, typically within an hour of birth.

Where you choose to give birth can vary, from home births and birth centres (which offer a more homely feel with midwife support) to hospital settings. Your medical history and any risk factors will influence the available choices and the level of support provided. For instance, a C-section would always take place in a hospital, and first-time mothers are often advised to give birth in a birth centre or hospital.

The Hormonal Orchestra of Childbirth

The entire process of labour and birth is orchestrated by a fascinating interplay of hormones. One key player is oxytocin, often called the “hug hormone.” Oxytocin has a positive feedback loop: the more it’s released, the more it encourages its own production. Levels are extremely high during labour, helping to create and accelerate contractions, which is crucial for a smooth delivery. This hormone also plays a vital role in bonding and breastfeeding after birth.

Another important group of hormones are endorphins, which are the body’s natural pain relief. These are released during labour to help manage discomfort. While labour is undoubtedly a physically demanding and often painful event, focusing on the imminent arrival of your baby can help you through this exciting, albeit exhausting, time. Various pain relief options are available depending on the setting and your preferences, from paracetamol and ibuprofen to gas and air, and epidurals in a hospital setting.

Navigating the Postpartum Hormone Crash: Physical Changes

Once your baby is born, your body undergoes immediate and profound changes. The sudden drop in pregnancy hormones, particularly oestrogen and progesterone, leads to the postpartum hormone crash. This can manifest in several ways:

• Immediate Recovery and Skin-to-Skin Contact: Healthcare professionals will usually place your baby on your chest for skin-to-skin contact soon after birth. This helps calm the baby, regulates their temperature and breathing, and triggers the release of oxytocin in the mother, promoting bonding and aiding in uterine contractions to deliver the placenta.
• Perineal Tears: It’s common for around nine out of ten women who have vaginal births to experience some degree of perineal tearing. These tears are usually repaired with dissolvable stitches and take about a month to heal. It’s crucial to understand how to care for them and to seek support if you experience any unusual discomfort or signs of infection.
• Postpartum Bleeding (Lochia): You will experience bleeding for a couple of weeks after birth. It’s essential to use maternity pads instead of tampons for at least eight weeks to allow the body to cleanse itself and reduce the risk of infection.
• Breast Changes: Initially, your breasts will produce colostrum, a dense, creamy substance packed with vital nutrients and antibodies – exactly what your newborn needs. Around day three or four, your breasts will start producing more regular milk.
• Bladder Control: It’s quite normal to experience temporary bladder control issues, such as small leaks when coughing or laughing. Pelvic floor exercises are highly recommended to help regain control.
• Haemorrhoids: These are common post-birth. Staying well-hydrated and ensuring a diet rich in fibre can help keep stools soft and prevent constipation, which can exacerbate haemorrhoids.

The postpartum hormone crash contributes significantly to physical symptoms like night sweats, where you might wake up drenched in sweat due to plummeting oestrogen levels. Your body is also recovering from the immense physical effort of childbirth and, if breastfeeding, expending significant energy to produce milk. This requires extra calories (around 500 per day) and plenty of rest. For more information on maintaining a healthy diet and lifestyle, visit our section on healthy living.

Emotional Wellbeing and the Postpartum Hormone Crash

Beyond the physical changes, the postpartum hormone crash can have a profound impact on a new mother’s emotional state. Many women experience what is known as the “baby blues” in the first couple of weeks after birth. This involves mood swings, weepiness, irritability, and anxiety. These feelings are normal and usually subside as your hormones begin to stabilise.

However, if these feelings persist beyond four weeks, or if you feel overwhelmingly low, unable to cope with daily life, or disconnected from your baby, it might be a sign of postnatal depression. This is a common and treatable condition, and it’s incredibly important to talk to a healthcare professional if you are experiencing these symptoms. They can offer support and guidance on managing your mental health during this period. You can find more resources and support on our mental health topic page.

Supporting Your Body and Mind Through the Postpartum Hormone Crash

Recovering from childbirth and navigating the postpartum hormone crash takes time and patience. It’s a gradual process, and your body won’t return to its pre-pregnancy state overnight. Be kind to yourself and understand that this is a natural part of the journey. Metabolism also gradually adjusts, and if you experienced gestational diabetes, your blood sugar levels will be monitored around six to eight weeks postpartum, usually returning to normal. If not, your doctor will advise on appropriate medication. Learn more about managing conditions like diabetes and obesity on our website.

There can be a lot of pressure, especially for first-time mothers, to “get back in control” or to lose the weight gained during pregnancy. However, worrying too much about your weight during this intense time can hinder your ability to properly care for yourself and your baby. Focus on nourishing your body with plenty of fluids and fibre, and allow yourself the rest you need. For support with weight loss when you are ready, PillSorted can help.

In summary, labour is a meticulously designed biological process, and the hormonal changes that follow are significant. The postpartum hormone crash is a real phenomenon, and recovery takes time. Be patient with yourself, seek support when needed, and remember that PillSorted is here to provide clinician-led, safe advice for all aspects of women’s health.
