Within the First 72 Hours After Birth: The Largest Hormonal Shift in Human Life and the Importance of Postpartum Support

Discover how postpartum hormonal changes affect a mother’s physical and emotional health and why support is essential after childbirth.

The postpartum period is often focused almost entirely on the baby, but the mother’s physical and emotional recovery deserves equal attention. During the first 72 hours after childbirth, the female body experiences a dramatic drop in estrogen and progesterone, considered one of the largest hormonal shifts a human being can experience.

This phenomenon is not simply about “being emotional” or “sensitive.” It is a profound biological event that affects the nervous system, metabolism, sleep, emotional regulation, and cognitive function. Understanding this stage from both a medical and human perspective is essential to providing real support for mothers.

At Eggvise, we believe that conversations about fertility, IVF, motherhood, and reproductive health should also include education about what happens after birth.

What Happens Hormone-Wise After Childbirth?

During pregnancy, estrogen and progesterone levels increase dramatically to support the baby’s development. However, once delivery occurs and the placenta is expelled, these hormone levels drop abruptly.

In less than three days, hormone levels can decrease by more than 1,000%. This shift directly impacts multiple systems in the body:

• Emotional regulation

• Sleep quality

• Energy production

• Memory and concentration

• Immune system function

• Stress response

For this reason, many women experience sadness, anxiety, irritability, extreme exhaustion, or feelings of disconnection during the first postpartum days.

This does not mean weakness or inability. It is a completely real physiological response.

“Baby Blues” and Postpartum Mental Health

Approximately 70–80% of mothers experience what is known as the “baby blues,” a temporary period of emotional sensitivity that usually appears a few days after childbirth.

Common symptoms include:

• Unexpected crying

• Mood swings

• Anxiety

• Intense fatigue

• Difficulty sleeping

• Feeling overwhelmed

In most cases, these symptoms gradually improve. However, when they intensify or persist, they may indicate postpartum depression or postpartum anxiety, conditions that require professional attention.

Normalizing conversations around maternal mental health is essential so mothers can seek help without fear or guilt.

The Nervous System Is Also Recovering

The body is not only recovering from pregnancy and childbirth. The nervous system is also going through a major adjustment.

After months of elevated hormone levels, the brain must rapidly recalibrate. On top of this, mothers are also facing:

• Sleep deprivation

• Physical recovery

• Breastfeeding

• Lifestyle changes

• Emotional overload

Many mothers describe experiencing “brain fog” or difficulty processing information. This also has a biological basis.

Recognizing this can help reduce unrealistic expectations surrounding immediate motherhood.

Postpartum Support Should Not Be Optional

Historically, many cultures prioritized rest and intensive care for mothers during the weeks following childbirth. Today, many women face pressure to “bounce back” quickly.

However, postpartum support can make a tremendous difference in both physical and emotional recovery.

Support may include:

• Household help

• Proper rest

• Emotional support

• Access to mental health professionals

• Family or community support networks

• Education about hormonal recovery

The goal is not only to care for the baby, but also to care for the person who has just undergone one of the most intense physical transformations of human life.

The Connection Between Fertility, IVF, and Maternal Health

Conversations about fertility and IVF often focus on achieving pregnancy, but maternal health after birth is also an important part of the journey.

For many intended parents, understanding the postpartum period helps create more realistic and compassionate expectations regarding emotional and physical recovery after childbirth.

Within the field of egg donation and fertility treatments, comprehensive education is essential. Talking about responsible motherhood also means understanding both pregnancy and postpartum recovery.

As an egg donor agency, Eggvise believes it is important to provide clear, compassionate information about every stage of the reproductive journey.

Why Is It Important to Talk More About This?

For years, many postpartum experiences were minimized or dismissed as “normal emotional changes.” While some symptoms may indeed be common, that does not mean they should be ignored.

When we understand postpartum recovery as a complex biological event:

• Stigma decreases

• Mothers seek help earlier

• Families provide better support

• Emotional recovery improves

• Overall family health becomes stronger

Education can profoundly change the way we support mothers during this vulnerable stage.

The Importance of Information and Support

Motherhood should not be experienced in isolation. Whether through family support, medical professionals, or educational resources, having access to accurate information can make this transition more manageable.

At Eggvise, we believe reproductive education should be comprehensive. From egg donation and fertility treatment to the postpartum experience, every stage deserves attention, empathy, and understanding.
