Congenital Heart Disease (CHD) affects 1 in every 100 babies born worldwide. If your child has been diagnosed with CHD, you’re likely focused on surgeries, medications, and doctor visits. But there’s another crucial piece of your child’s care that deserves attention: nutrition.
Good nutrition isn’t just about feeding your child. For children with CHD, it’s part of their treatment plan. The right foods can help your child grow stronger, recover faster, and live better with their condition.
Why Children with CHD Need Extra Nutrition
Children with CHD face unique challenges when it comes to eating and growing:
Higher calorie needs: When the heart doesn’t work properly, it has to pump harder. This extra work burns more calories, even when your child is resting. Most children with CHD need more calories than other kids their age.
Feeding difficulties: Babies may get tired while eating and stop before they’re full. Older children might lose their appetite or need to limit fluids. This creates a problem where your child needs more nutrition but struggles to get it.
Hidden malnutrition: Your child might seem active and alert but still lack important nutrients. This can affect their growth, immune system, and ability to recover from illness or surgery.
What Is Congenital Heart Disease and What Causes It?
CHD isn’t one condition but a group of heart problems present at birth. These can affect the heart’s walls, valves, or blood vessels. Common types include atrial septal defects, tetralogy of Fallot, and transposition of the great arteries.
Several factors can increase the risk:
- Genetic changes (like those in Down syndrome)
- Infections during pregnancy (especially rubella)
- Maternal health issues like uncontrolled diabetes or obesity
- Nutritional deficiencies during pregnancy, particularly low folic acid
However, most cases are idiopathic, which means that they have no identifiable cause. This makes good prenatal care and maternal nutrition important for prevention.
Building a Heart-Healthy Diet for Your Child
The goal is to help your child get the nutrients they need in ways that work for their age and condition.
Key nutrients to focus on:
Protein: Helps build and repair tissue, especially after surgery. Good sources include lean meats, dairy products, eggs, and beans.
Healthy fats: Omega-3 fatty acids from fish and walnuts support heart health and reduce inflammation.
Whole grains: Provide steady energy that can help with endurance throughout the day.
Fruits and vegetables: Supply vitamins and antioxidants that boost recovery and strengthen the immune system.
Important vitamins and minerals:
- Iron helps transport oxygen throughout the body
- Calcium and vitamin D build strong bones (especially important for children with limited mobility or on certain medications)
Common Nutritional Problems and Solutions
Iron deficiency is common in children with CHD and can cause fatigue and make physical activity harder. Your doctor can test for this with a simple blood test.
Vitamin D and calcium deficiencies often occur, especially in children who don’t get enough sunlight or have dietary restrictions. These may not cause obvious symptoms right away but can affect growth and energy over time.
Regular screening and early intervention are key. Sometimes dietary changes are enough. Other times, supplements are necessary. Always work with your healthcare team rather than guessing what your child needs.
Foods to Limit in Congenital Heart Disease
Some foods can make CHD symptoms worse:
High-salt processed foods can cause fluid retention, putting extra strain on the heart. This includes packaged snacks, canned soups, and fast food.
Sugary drinks and snacks provide empty calories without useful nutrients. Over time, these can lead to weight gain without supporting your child’s health needs.
You don’t need to eliminate everything. Focus on balance: choose whole foods over processed ones, cook more meals at home, and use fresh ingredients when possible.

When Food Isn’t Enough
Sometimes oral feeding alone won’t meet your child’s needs. This might happen during illness, after surgery, or if growth is falling behind. You can use the following ways to support your child’s health:
- High-calorie drinks or nutritional supplements
- Tube feeding (temporary, until oral feeding improves)
- Smaller, more frequent meals instead of three large ones
Each child’s needs are different, and nutrition plans should be personalized.
Working with Your Healthcare Team
Caring for a child with CHD is a long-term commitment. Nutritional needs change as your child grows. What works for a baby won’t be right for a school-going child.
Your team should include:
- Pediatric cardiologist
- Registered dietitian
- Nurses
- You and your family
Regular check-ins help ensure your child’s nutrition plan stays on track. Don’t hesitate to ask questions or voice concerns about eating, growth, or supplements.

Looking Forward: Quality of Life Matters
More children with Congenital Heart Disease are surviving into adulthood than ever before. This shift means focusing not just on survival, but on helping your child live well. Nutrition plays a major role in this goal.
Good nutrition helps determine how well your child grows, how strong they become, and how resilient they remain throughout their life. Progress isn’t just measured in successful surgeries or adjusted medications. It’s also measured in meals finished, nutrients absorbed, and strength gained.
For children with CHD, every meal matters.
Frequently Asked Questions for Quick Reference
Q: Why do children with Congenital Heart Disease need more calories than other children? A: When the heart doesn’t work properly, it has to pump harder. This extra work burns more energy, even when your child is resting. Most children with CHD need more calories than other kids their age.
Q: Why might my child with CHD have trouble eating? A: Babies may get tired while eating and stop before they’re full. Older children might lose their appetite or need to limit fluids. This creates a problem where your child needs more nutrition but struggles to get it.
Q: Can my child appear healthy but still have nutritional problems? A: Yes. Your child might seem active and alert but still lack important nutrients. This hidden malnutrition can affect their growth, immune system, and ability to recover from illness or surgery.
Q: What nutrients are most important for children with CHD? A: Key nutrients include protein (for building and repairing tissue), healthy fats like omega-3s (for heart health), whole grains (for steady energy), and fruits and vegetables (for vitamins and immune support). Iron, calcium, and vitamin D are also particularly important.
Q: What nutritional deficiencies are common in children with CHD? A: Iron deficiency is often seen and can cause fatigue. Vitamin D and calcium deficiencies are also common, especially in children who don’t get enough sunlight or have dietary restrictions. These may not cause obvious symptoms right away but can affect growth and energy over time.
Q: What foods should I limit for my child with CHD? A: High-salt processed foods can cause fluid retention, putting extra strain on the heart. Sugary drinks and snacks provide empty calories without useful nutrients. Focus on balance rather than elimination.
Q: When might my child need feeding support beyond regular meals? A: Sometimes oral feeding alone won’t meet your child’s needs during illness, after surgery, or if growth is falling behind. Options may include high-calorie drinks or temporary tube feeding until oral feeding improves.
Q: Will my child’s nutritional needs change over time? A: Yes. What works for a baby won’t be right for a school-age child. Nutritional needs change as your child grows, which is why regular check-ins with your healthcare team are important.
