Why Weight Management Matters for VBAC Safety and Success

Choosing VBAC is a brave and hopeful step many individuals take. You might want to recover quickly, give birth naturally, or build a strong connection with your baby after delivery. However, weight management is a key factor that is often overlooked when making this decision.

What Is a VBAC & Why Is It Considered Carefully?

A VBAC is when you have a normal birth after you had a C-section before. Lots of individuals can do it safely. About 60% to 80% of individuals who try for a VBAC can have a successful vaginal birth.

However, doctors consider several factors first to determine if it’s a good idea for you. This includes:

The reason for the need for a C-section last time
The time gap between two pregnancies
The way your scar healed
Your overall weight and health

Weight plays a silent but powerful role in how your body handles labour, healing, and potential complications.

How Does Your Weight Affect the Safety of a VBAC?

Your weight significantly impacts your body's endurance, hormonal balance, and the growth of your baby. When you're getting ready for a VBAC, here's how weight management becomes crucial:

Being overweight can make labour harder and take longer since extra fat can hamper your uterine contractions
Extra fat can also put more stress on your C-section scar, which may increase the risk of tearing a bit more
If you’ve a high BMI or Body Mass Index, you’re more likely to get high blood pressure or gestational diabetes, which can make a VBAC riskier
If you need an emergency C-section, being overweight can make it harder to get anaesthesia and heal afterwards

Maintaining a balanced weight helps mitigate the risks and prepares your body for a vaginal delivery.

What Can Being Overweight Cause During a VBAC Attempt?

Being overweight doesn't mean you're not eligible for VBAC; it just means your doctor will pay more attention to you. Studies show that individuals with a BMI over 30 have a slightly harder time with a VBAC, often due to slow labour or more medical help being needed.

This could mean:

A higher possibility you’ll need to have your labour induced
Slower dilation of the cervix
A higher chance of wound infections if you end up needing surgery

Can Being Underweight Impact VBAC, too?

Yes, though it’s not common, being underweight can cause problems. Low weight may lead to weaker muscles or nutritional deficiencies, which can affect your stamina during labour. It can also increase the risk of having an underweight baby, which may bring other complications.

Balancing your weight is the key.

How Much Weight Should You Gain for a Successful VBAC?

According to medical guidelines, it really depends on your BMI before you conceive:

If you were of normal weight (BMI 18.5 - 24.9), aim to gain about 11 to 16 kg
If you are overweight (BMI 25-29.9), target a weight loss of about 7–11 kg
If you were obese (BMI ≥30), you shouldn’t gain more than 5 to 9 kg

Emotional & Social Aspects of Weight Gain

Weight can sometimes affect your confidence, particularly when you're preparing for labour. Feeling stressed or anxious about your body is a normal reaction. Just remember that your ability and worth to have a baby aren’t about a number.

Talk to your partner or family about what’s bothering you. Having people who support you can make a significant difference in managing stress and maintaining your health. For a successful VBAC, emotional strength is as important as physical readiness.

When to Discuss Weight Management with Your Doctor?

You should discuss your weight with your doctor as early in pregnancy as possible, or ideally, before conception. See a doctor right away if you notice:

Puffiness in your face, hands, or feet
Quick or surprising weight gain
Feeling extremely tired or having trouble breathing
Signs of gestational diabetes or high blood pressure

These symptoms could indicate complications that need medical intervention.

What Are the Further Steps?

Ask about the ideal range of weight to maintain during and before pregnancy
Keep a food and exercise diary to stay on track
Attend your doctor’s appointments regularly to monitor your blood pressure, weight, and blood sugar levels
Discuss VBAC options beforehand with your healthcare team so they can take the necessary actions accordingly
Seek emotional support from your friends, partner, or a counsellor if you feel stressed about your body changes
