What Is Oestrogen and What Does It Do During Pregnancy?
Oestrogen is a natural hormone found in everyone, but can be produced in larger amounts in some individuals. During pregnancy, your oestrogen levels can increase up to 30 times from their normal range. This hormone helps:- During your baby’s organ development.
- Strengthening the connection between you and your baby through the placenta.
- Preparing your uterus and breasts for childbirth and breastfeeding
How Does Oestrogen Reach Your Baby Girl?
During pregnancy, your placenta acts as a lifeline. It connects your bloodstream with your baby’s, allowing nutrients and hormones to pass through safely. Oestrogen made by your body (and later by the placenta) flows through this connection. The baby’s body uses these hormones as signals to properly develop organs, tissues, and systems. Think of it like this: The oestrogen that you produce works as a “messenger”, helping your baby’s tiny body understand when and how to grow.Why Does a Baby Girl Need Oestrogen Exposure in the Womb?
You might think about why your daughter needs oestrogen before she is even born. Early hormonal signals guide lifelong health. Oestrogen helps your baby girl in several ways.- Oestrogen is the hormone that ensures the proper growth of the reproductive organs —uterus, fallopian tubes, and vagina — in the foetus.
- This hormone also plays a crucial role in the development of areas of the brain associated with emotions, memory, and hormonal balance.
- Oestrogen helps in the development of early calcium storage and bone density.
- It plays a crucial role in determining how the baby’s body will store fat later, thereby supporting overall metabolism.
Can Too Much Oestrogen Affect the Baby?
Oestrogen levels typically remain within a healthy limit, promoting the development of your body normally in most pregnancy cases. Still, in rare cases, an imbalance in hormones can also occur due to the following reasons:- If you were on a certain medication or had gone through some fertility procedure.
- Gestational complications such as diabetes.
- Placental problems.
- Slight breast swelling.
- Small amounts of vaginal discharge or mild bleeding (known as “mini periods”).
What Happens After Birth?
The amount of oestrogen drops from the baby girl’s body after birth as she is no longer supplied with it by your body. This sudden change can cause mild, short-term effects such as:- Swollen nipples
- A small amount of discharge, with a clear or milky texture
- Slight swelling in the genitals
How Can You Support Healthy Hormone Balance During Pregnancy?
Managing your body's hormones well benefits both you and the baby.- Include fresh fruits, leafy greens, and whole grains in your meals. Ensure a healthy diet throughout your pregnancy.
- Good sleep helps regulate hormonal balance naturally.
- Gentle exercises and workouts improve hormone stability and overall body health.
- Always check with your doctor before taking any new supplements, medication, etc.
- Stress can cause an imbalance in hormonal production. Try breathing exercises or some meditation.
When Should You See a Doctor?
You are in a fragile state, so it's essential to discuss your condition, especially any unusual symptoms, with your doctor.- Constant headache or severe swelling in the body can be a sign of a complication in the pregnancy.
- Sudden change in vision.
- Unusual bleeding or pain.
What To Do Next: A Simple Checklist
- Eat food rich in nutrients, and opt for home-cooked meals.
- Consult your doctor before taking any vitamins or supplements.
- Drink water frequently and don’t avoid rest.
- You are a unique individual, so don’t compare your pregnancy with anyone else.
Emotional and Social Aspects
Pregnancy can feel heavy sometimes; it can shake up your emotions, especially when you learn how your body’s hormones affect your baby. It’s okay to feel curious or even overwhelmed. Discuss openly with your partner or family your feelings and emotions. You feel more confident and calm when you share your feelings.Remember, your baby’s growth is a beautiful reflection of your body’s strength and care. Every hormone, every heartbeat, is part of the miracle you’re nurturing inside.
A baby girl's reproductive system, bones, brain and metabolism are shaped and developed through her exposure to oestrogen in the womb, which is a natural and essential part of her growth. While a few temporary effects may appear after birth, they’re usually harmless and fade quickly.
By focusing on a healthy lifestyle, keeping up with your doctor’s prescription, and staying informed, you ensure that both you and your little girl come out through every stage of pregnancy.
