Can a Baby Grow Again After Growth Stops? Causes, Signs & What You Can DoFetal growth restriction is one of the most worrying concerns for any expecting mother. It often raises a serious question: Can the baby start growing again after their growth has stopped? This issue can be stressful, especially when a delay in the baby’s development is discovered during routine check-ups.In this Dalili Medical article, we’ll explore the possible reasons behind a temporary stop in fetal growth, whether the baby can return to normal development, and the key warning signs that you shouldn’t ignore. We’ll also guide you on how to properly monitor your pregnancy to protect both your health and your baby’s.Stay with us to learn all the essential information every mother needs to know about fetal growth concerns.

When Does a Baby’s Heartbeat Start – and When Can It Be Measured?

A baby’s heartbeat usually begins around the 6th week of pregnancy, and it’s considered the first clear sign of life inside the womb. Doctors typically schedule the first ultrasound (either abdominal or transvaginal) between 6 and 7 weeks to detect the heartbeat clearly.

Hearing your baby’s heartbeat for the first time is a joyful moment—it reassures you that your baby is alive and developing well.

Can the Baby’s Heartbeat Come Back After It Stops?

This is a very important point: if the baby’s heartbeat stops, it usually doesn’t come back. However, sometimes an early ultrasound (especially before 7 weeks) might not detect the heartbeat clearly, leading to a false alarm.

That’s why doctors often recommend repeating the scan after a few days. But if it’s confirmed that the heartbeat has stopped, the pregnancy may need to be terminated to protect the mother’s health, as continuing the pregnancy could lead to serious complications.

Does Slowed Growth Mean the Baby Has Died?

Not always. Sometimes the baby’s growth is just slower than expected and may improve later in pregnancy, especially during the second and third trimesters.

However, if growth stops before 20 weeks, it could be a sign of a more serious problem that may threaten the baby’s life. That’s why close monitoring and regular prenatal checkups are critical.

How to Boost Your Baby’s Growth Naturally During Pregnancy

There isn’t one specific food that directly increases fetal weight, but what’s most important is to follow a balanced and healthy diet throughout your pregnancy. Focus on:

Fresh fruits and vegetables
Whole grains (like oats and whole wheat)
Lean proteins (chicken, meat, eggs, legumes)

These foods provide all the vitamins and minerals your baby needs for healthy development.

Can Stress and Fatigue Affect Baby’s Growth?

Yes. Chronic stress and physical exhaustion can negatively impact the baby’s growth. Studies show that when a mother is constantly stressed, her body uses more energy, which reduces the amount of oxygen and nutrients reaching the baby.

To manage stress during pregnancy, try:

Deep breathing exercises
Light stretching or prenatal yoga
Taking enough breaks and rest periods

Emotional well-being is essential for your baby’s healthy growth.

Stages of Fetal Growth Delay and Their Causes – Simplified Guide

1. First Trimester (Weeks 1–12)

The baby is still forming and is very sensitive to any health issues. Common causes of early growth restriction include:

Birth defects or genetic disorders
Viral infections (like rubella)
Hormonal problems in the mother (e.g. thyroid dysfunction or low pregnancy hormones)

2. Second Trimester (Weeks 13–26)

This is when fetal growth becomes more noticeable. Slowed growth during this stage can be due to:

Poor blood flow to the placenta
Gestational diabetes or high blood pressure
Smoking or secondhand smoke exposure

3. Third Trimester (Weeks 27–40)

This is when the baby gains the most weight. Delayed growth here is more dangerous, especially near delivery. Causes include:

Placental or umbilical cord issues
Maternal diseases (like kidney or liver problems)
Multiple pregnancies (twins, triplets)

When and How Is Intrauterine Growth Restriction (IUGR) Detected?

Usually, fetal growth problems are noticed after 20 weeks of pregnancy. During prenatal visits, doctors measure the fundal height (the distance from the pubic bone to the top of the uterus). If this measurement is smaller than expected, further testing is done using ultrasound.

Top Causes of Fetal Growth Delay or Restriction

Placental problems
Poor blood flow means the baby gets less oxygen and nutrition.
High blood pressure (preeclampsia)
Reduces blood supply to the placenta.
Gestational diabetes or chronic illnesses
Heart, kidney, or autoimmune diseases can affect both mother and baby.
Smoking, alcohol, or drug use
Reduces oxygen flow to the baby.
Poor maternal nutrition
Lack of essential vitamins and minerals leads to poor fetal growth.
Infections during pregnancy
Bacterial or viral infections may interfere with development.
Fetal abnormalities
Genetic issues or birth defects can limit growth.
Multiple pregnancies
Twins or more can compete for nutrition.
Low amniotic fluid (oligohydramnios)
Can restrict baby’s movement and growth.
Maternal anemia
Severe iron deficiency reduces oxygen delivery to the baby.
Chronic stress or emotional trauma
Affects the mother's overall health and the baby's growth.
Unsafe medications
Certain drugs can harm fetal development if not taken under medical supervision.
Umbilical cord problems
Compressed or twisted cord limits blood flow.
Premature birth
Early delivery interrupts the full development process.
Genetic factors
Some babies are naturally smaller due to inherited traits.

How Is Fetal Growth Restriction Diagnosed?

Fundal height measurement
Done in every check-up. Smaller size could signal growth delay.
Ultrasound scan
Used to check:

Head and abdominal circumference
Femur length
Amniotic fluid levels
Estimated fetal weight

If the baby measures 10% or more below expected weight, IUGR is suspected.

Doppler ultrasound (blood flow scan)
Checks blood flow between the placenta and baby.
Monitoring fetal movement
A noticeable decrease in movement is a warning sign and needs urgent attention.
Non-stress test (NST)
Measures fetal heart rate and response to movement.
Blood tests for the mother
To check for:

Anemia
Gestational diabetes
High blood pressure
Infections

Top 10 Tips to Prevent Fetal Growth Delay or Stoppage

1. Regular Prenatal Checkups
Always follow up with your doctor as scheduled. Get ultrasounds and tests on time to detect any issues early.
Tip: Don’t skip any appointments, even if you feel fine.

2. Eat a Healthy and Balanced Diet
Make sure your meals include vegetables, fruits, proteins, and whole grains. Avoid junk food and excess sugar.
Tip: Take folic acid and prenatal vitamins regularly.

3. Get Enough Rest
Fatigue and stress can affect fetal development. Sleep well and take breaks throughout the day.
Tip: Aim for 7–9 hours of sleep at night, plus a short nap if needed.

4. Stay Hydrated
Drinking enough water improves blood circulation and oxygen flow to the baby. It also supports the placenta’s function.
Tip: Drink at least 8 to 10 cups of water daily.

5. Avoid Smoking and Unprescribed Medications
Smoking reduces oxygen to the baby, and some medications can be harmful.
Tip: Don’t take any medication without consulting your doctor.

6. Reduce Stress and Anxiety
Stress can affect fetal growth. Try light exercises like walking and schedule time to relax.
Tip: Set aside 15 minutes a day just for rest or calm activities.

7. Take Care of Your Hygiene and Health
Treat any infections promptly, especially urinary or vaginal infections.
Tip: See a doctor immediately if you notice burning or unusual discharge.

8. Monitor Blood Pressure and Blood Sugar
High levels can harm your baby, so keep them in check with your doctor.
Tip: Track your readings and write them down.

9. Track Fetal Movement Starting Month 5
If movement decreases or stops suddenly, this could be a warning sign.
Tip: Pay attention to movement, especially after meals.

10. Get Recommended Vaccines
Vaccines like the flu shot help protect both you and your baby from harmful illnesses.
Tip: Ask your doctor which vaccines are suitable for your stage of pregnancy.

Treatment of Intrauterine Growth Restriction (IUGR)

When fetal growth slows or stops, it's critical to act fast. Treatment depends on the cause, severity, and gestational age and must be managed by a gynecologist.

1. Regular Monitoring

Ultrasounds: Weekly or bi-weekly to check weight, amniotic fluid, and blood flow in the placenta.
Fetal Heart Monitoring (NST): Tracks baby’s heartbeat and movements.
If the condition is stable, pregnancy may continue without further intervention.

2. Lifestyle Changes

Rest: If blood flow to the placenta is low, your doctor may advise bed rest to increase oxygen to the baby.
Healthy Diet: Focus on foods rich in protein, iron, fruits, and vegetables. Your doctor may recommend supplements.
Hydration: Drink 8–10 cups of water daily.
Quit Smoking and Caffeine: Both reduce oxygen delivery to the baby.

3. Treat Underlying Causes

High Blood Pressure/Pre-eclampsia: Managed with pregnancy-safe medication.
Gestational Diabetes: Controlled with diet or insulin.
Infections: Treated with pregnancy-safe antibiotics.

4. Early Delivery (in severe cases)

If the womb becomes unsafe for the baby, early delivery may be necessary, especially after 34 weeks.
A C-section may be required to reduce risks.
Steroid shots (corticosteroids) might be given before early delivery to speed up lung development.
