There is one cause that is most commonly at the crux of all of these symptoms, as well as rashes, diarrhea,
constipation, and wild behavior: allergy
to or intolerance of certain food proteins — most often from cow's milk, but also
sometimes from wheat, soy, and an array of other foods consumed by breastfeeding mom, in formula, or otherwise in baby's diet.8 These can cause irritation and inflammation in the intestines that
lead at times
to reflux, and more often
to signs of distress that mimic reflux.
Another type of IBD, Crohn's disease can cause abdominal pain (especially in the right lower quadrant), diarrhea,
sometimes bloody stool, fatigue, weight loss and, over time, bowel obstruction (
leading to constipation) and even malnutrition.
