Distinguishing between normal and potential abnormalities in infants is a challenge for all parents. Pediatricians often hear questions about frequent crying or spitting and noisy breathing. Although these behaviors may be normal, they sometimes indicate potential problems - such as formula intolerance or allergies. Formulation intolerance is a reaction to the ingredients of the formula that can irritate the baby's digestive tract and may cause systemic inflammation. Formula allergy is the immune system response to the protein in the formula. Although formula allergies and intolerances are different, the symptoms are usually similar and these terms are often used interchangeably.

Spitting and vomiting
Many babies have a harmless amount of spitting after feeding. If your baby is not painful or powerful and gains weight, this may not be a concern. However, vomiting may be a sign of formula intolerance or other serious illness, when it persists, accompanied by irritability, underweight and bloating. Milk protein and soy protein are the most common causes of these reactions.
Diarrhea episodes
It is sometimes difficult for parents to distinguish normal baby stools from diarrhea. Infant feces are usually slightly loose and frequent compared to adults. Some newborns get up to 8 stools a day. However, if your baby has a watery stool, too much stool or mucus in the stool, he may experience formula intolerance. Bloody stools may also have formula allergies, or they may point to more serious things.
rash
Atopic dermatitis is an itchy scaly rash often accompanied by food allergies. The August 2012 medical position document published in Pediatric Gastroenterology and Nutrition noted that 50% of infants allergic to milk formula also have atopic dermatitis. The rash mainly appears on the baby's face, scalp, arms and legs. Formula anaphylaxis may also occur in urticaria.
Attack Colic
Colic is defined as a few hours of irritability, usually occurring between 3 weeks and 3 months. About 20% of babies are outNow colic, which is characterized by crying and uneasy, is usually at night, bloating, signs of gas and abdominal pain - such as pulling legs. Although colic is often unexplained, in rare cases it is caused by intolerance to infant formula.
Wheezing and other respiratory symptoms
Wheezing - High-pitched noise from breathing caused by breathing and narrowing of airways - About 20% to 25% of infants develop food allergies. Other possible respiratory symptoms include chronic cough, stuffy nose and runny nose. Respiratory symptoms caused by food allergies are usually associated with skin rashes and digestive symptoms associated with combination therapy.
Next Steps
If you suspect that your baby has formula intolerance, please consult your pediatrician. Symptoms such as wheezing and underweight may indicate serious problems, so it is important to properly evaluate your baby to determine formulation intolerance or other possible causes. If your baby has difficulty breathing, see a doctor immediately. Fortunately, once the violation formula is replaced by a well-tolerated formula, the symptoms caused by formula intolerance usually decrease rapidly.
