Symptom Guide


Symptom Guide

Unfortunately, infants and very young children cannot use words to tell you what’s wrong. But physical symptoms can speak volumes if you know what you’re looking for.

Symptoms of a milk allergy or milk allergy-related conditions can be as diverse as inconsolable crying, baby rash, diarrhea, vomiting and wheezing. This guide should help you identify symptoms so you can discuss them with your doctor and dietitian.

  • Acid reflux

    The flow of stomach contents back into the esophagus and/or mouth. Also referred to as gastroesophageal reflux. Acid reflux in children and infants is normal, usually occurring briefly and without causing symptoms or complications. In contrast to acid reflux, infants and children with gastroesophageal reflux disease (GERD) can experience symptoms, such as heartburn, vomiting or pain with swallowing, as a result of the reflux. There may also be cases in which infants and children have GERD symptoms listed above without experiencing any vomiting or spit-up. This is typically referred to as silent reflux.
  • Colic

    Excessive crying that typically lasts for more than three hours a day and happens at least three days a week for more than three weeks.
  • Constipation

    Bowel movements that are infrequent and hard to pass.
  • Diarrhea

    Bowel movements that occur more frequently and are more watery in consistency than normal. It can be caused by toxins or bacterial, viral and parasitic infections, but also by food allergies, digestive system diseases (stomach, liver, pancreas), or intestinal inflammatory diseases (Crohn’s disease, ulcerative colitis). Severe diarrhea could lead to dehydration quickly.
  • Vomiting

    A reflex forcing the contents of the stomach up through the esophagus and out the mouth.
