What Is Necrotizing Enterocolitis?

Necrotizing enterocolitis (NEC) is one of the most severe and life-threatening conditions that can affect a newborn, particularly premature infants. This gastrointestinal disorder causes inflammation and tissue death in the intestines, leading to devastating complications if untreated.

NEC typically strikes within the first few weeks of life, and its symptoms can escalate quickly. Parents often notice alarming changes, such as:

• Abdominal swelling or tenderness.
• Difficulty feeding or sudden intolerance to feedings.
• Blood in the stool, indicating intestinal damage.
• Unexplained lethargy or changes in behavior.

While NEC is relatively rare—affecting approximately 1 in 1,000 live births—it disproportionately impacts premature and low birth weight babies. These infants, born before their digestive systems are fully developed, face heightened risks when exposed to certain feeding practices, particularly formula feeding.

The Science Linking Infant Formula to NEC

For decades, researchers have investigated the connection between infant feeding practices and the risk of necrotizing enterocolitis (NEC). While some studies suggest an association between cow’s milk-based formulas and NEC in premature infants, the relationship is far from straightforward. 

What Makes Cow’s Milk-Based Formula Risky?

Cow’s milk-based formulas are designed to meet the nutritional needs of infants who cannot breastfeed. However, these products lack the immune-boosting and protective properties naturally found in breast milk. 

Researchers have proposed several mechanisms that could explain why formula-fed premature infants may face an increased risk of NEC:

• Lack of Antibodies: Breast milk contains immunoglobulins, which strengthen an infant's immune defenses against infections and inflammation. Formula does not provide these immune components.
• Inadequate Gut Protection: Breast milk encourages the growth of beneficial gut bacteria, creating a protective barrier against harmful pathogens. Formula-fed infants, by contrast, may develop an imbalanced gut microbiota, making their intestines more vulnerable to inflammation and infection.
• Difficult Digestion: Proteins in cow’s milk, such as whey and casein, are harder for premature digestive systems to break down. This can lead to an inflammatory response in the immature gut.
• Timing of Exposure: Some studies have observed that NEC often develops shortly after the introduction of bovine products, even in infants who were initially breastfed.

It’s important to note, however, that while this hypothesis could explain a possible causal link between cow’s milk-based formula and NEC, the actual research does not currently support a firm conclusion.

Correlation vs. Causation

Correlation indicates a relationship between two variables, while causation implies that one variable directly causes a change in the other. In the case of cow's milk-based formula and NEC:

• While studies, such as one published in The Lancet by Lucas and Cole (1990), found that formula-fed preterm infants were 6 to 10 times more likely to develop NEC, other factors may also play significant roles.
• This correlation alone does not prove that the formula directly causes NEC.

Several factors complicate the establishment of a causal relationship:

• Confounding Factors: Premature infants who receive formula may already be at greater risk due to other factors, such as rapid feeding advancements or underlying health issues. These factors may skew the perceived link between formula and NEC.
• Variable Risk Levels: A 2020 study reported a 4.2-fold increased risk of NEC and a 5.1-fold increased risk of NEC surgery or death among preterm infants receiving cow’s milk-based formula. However, this risk is not universal, and formula use alone cannot account for every case of NEC.
• Inconsistent Evidence: Some studies suggest a strong correlation between formula and NEC, while others find weaker or inconclusive associations.
  • One study identified potential threshold effects in the relationship between human milk feeding and NEC risk:
    • Low human milk group (≤54%): 28.1% NEC rate
    • High human milk group (>54%): 1.9% NEC rate
    • Exclusive formula group: 8.0% NEC rate
  • Interestingly, the exclusive formula group had a lower NEC rate than the low human milk group, indicating that the protective effects of human milk may only become significant above a certain threshold.
  • The scientific community agrees that further research is needed to clarify these discrepancies.
• Ethical Considerations: Conducting randomized controlled trials to definitively prove causation would be unethical, given the potential risks to vulnerable infants.

Could NEC Be Linked to Other Factors?

As touched on before, while some studies highlight an association between cow’s milk-based formula and NEC, current research emphasizes that NEC is multifactorial, with various contributing influences working together to create a "perfect storm."

Prematurity and Low Birth Weight

Prematurity is the strongest and most consistent predictor of NEC. Infants born before 32 weeks of gestation or weighing less than 1,500 grams are at the highest risk due to several physiological vulnerabilities:

• Immature Gastrointestinal Systems: The underdeveloped gut lining in preterm infants is more susceptible to damage and inflammation.
• Underdeveloped Immune Responses: Premature babies lack the robust immune defenses needed to fight off infections that may lead to NEC.
• Compromised Intestinal Barrier Function: A fragile intestinal barrier allows harmful bacteria to penetrate more easily, leading to inflammation and necrosis.

Medical Conditions and Interventions

Several medical conditions and interventions commonly associated with preterm infants have been linked to NEC:

• Septicemia: Systemic infections can weaken the infant's ability to fight off inflammation and intestinal damage.
• Congenital Heart Disease: Reduced blood flow to the intestines can compromise gut health, making infants more vulnerable to NEC.
• Respiratory Distress Syndrome and Pneumonia: These conditions, along with their treatments (e.g., mechanical ventilation), may indirectly contribute to NEC by affecting overall organ function.
• Blood Transfusions: While lifesaving, blood transfusions have been observed to correlate with an increased risk of NEC, particularly when coupled with formula feeding.
• Prolonged Parenteral Feeding: Extended reliance on intravenous nutrition instead of enteral feeding can impact gut development and function, potentially increasing NEC risk when feeds are introduced.

Maternal and Genetic Factors

Maternal health and genetics also play a role in the likelihood of NEC:

• Maternal Conditions:
  • Gestational Diabetes: This condition may alter fetal development in ways that increase NEC susceptibility.
  • Premature Rupture of Membranes: This complication can lead to infections or early delivery, both of which elevate NEC risk.
• Genetic Predisposition:
  Emerging research suggests that certain genetic variations affecting immune regulation and gut function may predispose infants to NEC. While this area is still being explored, genetics likely contribute to why some infants develop NEC under similar conditions while others do not.

Gut Microbiota and Other Influences

The balance of bacteria in an infant’s gut, known as the microbiota, plays a central role in gut health. Preterm infants often have imbalanced microbiota due to antibiotic use, NICU exposure, or formula feeding, leaving them vulnerable to harmful bacteria that can trigger NEC.

Other Protective Factors

Factors other than breastfeeding have been shown to reduce the likelihood of NEC:

• Probiotic Supplementation: In some studies, adding probiotics to an infant's diet has been linked to lower NEC incidence.
• Prenatal Glucocorticoids: Administered to mothers at risk of preterm delivery, these steroids may help improve the infant’s lung and gut maturity.
• Hyperbilirubinemia: Interestingly, higher bilirubin levels have been associated with reduced NEC risk, though the mechanisms remain unclear.

Can I Take Legal Action Without Proven Causation?

Despite the absence of definitively proven causation, it is still possible to take legal action if your baby develops NEC after consuming cow's milk-based formula. Here's why:

Failure to Warn: A Manufacturer’s Duty

Under U.S. product liability laws, manufacturers have a legal obligation to warn consumers of known risks associated with their products. This duty stems from principles outlined in the Restatement (Second) of Torts, Section 402A, which holds manufacturers strictly liable for harm caused by unreasonably dangerous products.

In the context of NEC, there are already lawsuits that allege that formula companies, such as Abbott Laboratories (makers of Similac) and Mead Johnson (makers of Enfamil), failed to:

• Disclose the potential risks of NEC linked to cow’s milk-based formula on their product labels.
• Provide adequate warnings to parents and healthcare providers, even as studies began to reveal an association between formula use and NEC in premature infants.
• Investigate or mitigate risks despite emerging research pointing to the vulnerabilities of formula-fed preterm babies.

Plaintiffs argue that this failure to warn deprived parents of the opportunity to make informed decisions about their child’s nutrition, potentially leading to life-threatening consequences.

Preponderance of Evidence: The Standard of Proof in Civil Cases

Unlike criminal trials, where the burden of proof is "beyond a reasonable doubt," civil lawsuits operate on a lower standard: preponderance of evidence. This means that plaintiffs must show it is "more likely than not" that the formula contributed to NEC.

Courts often consider factors such as:

• Scientific studies demonstrating a statistically significant association between formula use and increased NEC risk.
• The timing and circumstances of NEC development relative to the use of cow’s milk-based formula.
• Internal documents from manufacturers, which may reveal whether they were aware of potential risks and chose not to disclose them.

The preponderance standard allows parents to seek justice even when definitive scientific causation remains elusive, especially in cases where the weight of evidence points to formula as a contributing factor.

What to Do if Your Baby Was Diagnosed with NEC

Facing a diagnosis of necrotizing enterocolitis (NEC) in your newborn often leaves parents with unanswered questions and a profound sense of injustice, particularly when formula feeding may have contributed to the condition. 

Fortunately, there are clear steps you can take to protect your baby’s health and pursue legal remedies for the harm your family has suffered.

1. Prioritize Your Baby’s Medical Care

The first step is ensuring your baby receives immediate and appropriate medical attention. NEC often requires intensive treatment, which may include:

• Antibiotics to address infections and prevent further complications.
• Bowel Rest and IV Nutrition to allow the intestines to heal while providing necessary nutrients.
• Surgery in severe cases where damaged tissue must be removed.

Keep detailed records of your baby’s symptoms, treatments, and any complications, as these documents will also be important if you decide to pursue legal action.

2. Gather Evidence About Feeding Practices

If your baby was fed formula, document:

• The brand and type of formula used (e.g., Similac, Enfamil).
• Any specific product labels, packaging, or marketing materials suggesting the formula was safe for premature infants.
• Feeding schedules and any observed reactions or symptoms.

This information helps establish a timeline and supports claims of negligence or failure to warn.

3. Understand Your Legal Rights

Parents of children affected by NEC have the right to pursue compensation for the damages they have endured, including:

• Medical Expenses: Covering the cost of treatments, surgeries, and ongoing care.
• Pain and Suffering: Addressing the emotional toll on both the infant and the family.
• Wrongful Death: In tragic cases, families may file claims to seek justice for their loss.

The specific legal remedies available to you will depend on your state’s statutes of limitations and product liability laws. For example, states like New York and California typically allow personal injury claims within two years of discovering the harm, but timelines vary across jurisdictions.
