Sometimes, newborns who receive baby formula can experience an upset stomach, diarrhea, or gas. If this occurs, it might be due to a dairy or soy allergy. The symptoms will usually go away once the infant is no longer being exposed to the allergen.
In rare cases, premature infants develop serious symptoms associated with NEC (necrotizing enterocolitis) after receiving cow’s milk-based baby formula such as Similac or Enfamil. Preterm babies are more likely to contract NEC when receiving bovine milk formula than they are when subsisting exclusively on human breast milk.
Common Infant Formula Side Effects
An upset stomach is one of the common side effects of using baby formula. If an infant is allergic to dairy and receives cow’s milk-based infant formula, they might show symptoms of an upset tummy. An upset stomach can also occur if infant formula is contaminated by bacteria like salmonella. The FDA recently recalled Similac (one of the popular bovine-milk-based baby formulas that has been shown to cause higher levels of NEC in preterm infants) after finding that some products were contaminated with Cronobacter bacteria, which can lead to life-threatening conditions, such as sepsis.
Some of the classic signs of an upset stomach after receiving formula include spitting up after feeding, vomiting after feeding, excessive flatulence, and crying or fussing.
If an upset stomach is caused by an allergy to cow’s milk, the infant may develop other symptoms of an allergic reaction. In addition to stomach issues, they might develop skin rashes and a stuffy nose.
Baby formula that does not contain the proper nutrition can also harm the infant receiving it. Baby formula products must abide by strict guidelines set by the FDA to ensure that babies receive all the nutrients they need from formula products. This is why the CDC encourages parents to avoid homemade infant formula as well as imported formula products that are not subject to FDA regulations.
Severe Side Effects of Baby Formula
Some babies experience a severe allergic reaction to bovine milk-based baby formulas. Depending on the severity of the allergy, consuming dairy could cause swelling in the mouth and throat, hives, and vomiting. Severe allergic reactions often require immediate emergency care. Not all allergic reactions show up right away. It may be days or weeks after an infant begins receiving cow’s-milk-based formula before they show symptoms of a dairy allergy.
NEC is another serious side effect of cow’s-milk-based formula products although it tends to primarily occur in premature infants, especially those who were born weighing less than two pounds. NEC rarely occurs in full-term babies, but about 1 in 1,000 premature babies suffers from the disease.
What Is NEC?
NEC is a gastrointestinal disease that can cause life-threatening complications. As bacteria from infant formula builds up in an infant’s intestinal tract, it can begin to erode the intestinal wall. Eventually, this can lead to perforations, or holes in the intestinal lining.
When holes form in the intestinal wall, bacteria are then allowed to seep out of the intestines and into the abdominal cavity, potentially infecting other organs. It can also leak into the bloodstream, which would cause the bacteria to circulate throughout the infant’s body.
Other common symptoms of NEC include green and yellow vomit, abdominal pain and swelling, bloody stools, diarrhea, lethargy, lack of appetite, and an inability to gain weight. NEC can occur in the small intestine, the large intestine, or both.
Some of the complications that can arise from NEC include sepsis, intestinal strictures, and short bowel syndrome.
Sepsis is a severe blood infection that is typically caused by bacterial infections. Intestinal strictures occur when the intestinal tract narrows, which can prevent food from freely passing through an infant’s bowel. Strictures are quite common in young infants who contract NEC, though they typically don’t appear until a few months after the infant has recovered from NEC.
Short bowel syndrome can occur if intestinal tissue is destroyed or damaged due to NEC. Short bowel syndrome can lead to a condition known as malabsorption. Malabsorption prevents the intestines from being able to properly absorb the nutrients found in food. These nutrients are necessary for babies to develop and grow. Infants who develop short bowel syndrome due to NEC may need care for the rest of their lives to ensure they get the proper nutrients.
Parents whose children were diagnosed with NEC after receiving products like Similac and Enfamil have filed lawsuits in numerous states against the manufacturers of these products, alleging that the manufacturers failed to disclose the potential dangers of bovine milk formula being given to premature infants.
