Healthy Weight Gain: Why It’s Important

Healthy weight gain during pregnancy is necessary to support your baby’s growth, the placenta, and your increased blood volume. While the amount of weight you should gain can vary depending on your pre-pregnancy BMI and whether you’re carrying multiples, knowing how much to gain can guide you in maintaining a healthy pregnancy.

• Underweight women (BMI < 18.5): Should gain about 13-18 kg (28-40 pounds)
• Normal weight women (BMI 18.5-24.9): Should gain about 11-16 kg (25-35 pounds)
• Overweight women (BMI 25-29.9): Should gain about 7-11 kg (15-25 pounds)
• Obese women (BMI ≥ 30): Should gain about 5-9 kg (11-20 pounds)

It’s essential to maintain a balanced diet and regular physical activity to stay within these recommended ranges. The right amount of weight gain supports your baby’s development and reduces the risk of complications.

What Affects Weight Gain During Pregnancy?

Several factors influence how much weight you gain during pregnancy. Let’s take a closer look at the variables:

• Pre-pregnancy weight: If you’re underweight, you may need to gain more weight. If you’re overweight, your weight gain may be more modest.
• Multiple pregnancies: Carrying twins or more will increase the amount of weight gained.
• Diet and nutrition: What you eat is just as important as how much you eat.
• Physical activity: Regular exercise, approved by your healthcare provider, can help manage your weight and keep you fit.
• Health conditions: Gestational diabetes or high blood pressure can affect weight gain patterns.

Weight Gain Month by Month

First Trimester (Weeks 1-12)

In the first trimester, most women gain a small amount of weight, often around 0.5 to 2 kg (1 to 4 pounds). Weight gain is generally minimal due to nausea, food aversions, or other symptoms, but it’s important to maintain a healthy diet as your body begins to adjust to pregnancy. Here’s what you can expect during this phase:

• Your baby is still tiny, and the weight gain is more about the changes happening within your body (increased blood volume, fluid retention, and hormonal shifts).
• Aim to eat small, frequent meals to help manage nausea and ensure you’re getting essential nutrients for both you and your baby.

If you are having trouble eating during this phase, you may find comfort in tips from experts like The Royal Women’s Hospital.

Second Trimester (Weeks 13-26)

The second trimester is often referred to as the “honeymoon phase” of pregnancy due to improved energy levels and reduced morning sickness. During this time, weight gain increases, and you can expect to gain 0.5 to 1 kg (1 to 2 pounds) per week. The baby is growing rapidly, and your body needs extra nutrients. Here’s what happens:

• As your baby grows, your appetite likely increases. This is a great time to focus on nutrient-dense foods that promote your baby’s development.
• Your weight gain in this phase is largely due to the growing baby, placenta, amniotic fluid, and extra blood.

Here are some tips for managing weight gain during this phase:

• Eat a balanced diet: Include plenty of fruits, vegetables, lean proteins, and whole grains.
• Stay active: Low-impact exercises like walking and swimming can help you stay fit and manage weight gain.

Third Trimester (Weeks 27-40)

The third trimester brings the most significant weight gain, as your baby grows rapidly. During this phase, you may gain 1 to 1.5 kg (2 to 3 pounds) per week. Here’s what to expect:

• Your baby’s weight increases significantly, and your body prepares for labor. The extra weight is from your growing baby, placenta, amniotic fluid, and increased fat stores.
• Although weight gain may feel more pronounced, it’s completely normal. Your doctor will monitor your health and recommend ways to manage excessive weight gain if necessary.

Tips for Managing Third-Trimester Weight Gain:

• Focus on portion control: While it’s important to eat nutrient-dense foods, avoid overeating.
• Exercise: Unless advised otherwise by your doctor, aim for regular light exercise.
• Stay hydrated: Proper hydration helps prevent water retention, which can add extra pounds.

Risks of Excessive Weight Gain

While weight gain is necessary during pregnancy, excessive weight gain can lead to complications such as:

• Gestational diabetes: High blood sugar during pregnancy.
• Increased risk of C-sections: Excess weight can complicate labor.
• Postpartum weight retention: It may be more difficult to lose weight after delivery.

Signs You’re Gaining Too Much Weight

It’s important to track your weight gain regularly. Your healthcare provider will guide you on what’s healthy. Red flags include:

• Gaining weight too quickly, particularly during the first trimester.
• Gaining more weight than the recommended range for your pre-pregnancy BMI.
