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.

You can also visit our Food Allergy Glossary for definitions of food allergies and GI-related terms.

Low Weight Gain

Gaining weight at a slower rate then other children who are at the same age and sex.

A child's weight and height generally track in a fairly consistent trend over time, albeit with some fluctuation.  This pattern can be described as a percentile on a growth curve.  By plotting a child's weight or height (length in the case of an infant or toddler) over time, a growth curve demonstrates their pattern of growth.  There is a range of possible reasons for why a child might gain weight slowly, and often more than one reason is contributing at a time.  Any factors that affect a child's access to food can affect weight gain.  Medically, anything that causes the following could be a contributing factor:

  • Inadequate food intake
  • Problems with digestion or absorption of food or absorption
  • Increased metabolism

Low weight gain may be a sign of a food allergy (caused by other food allergy reactions).  Children born prematurely (before their due date) are at particularly high risk for delays in weight gain.  Also, for some children - those with small parents, for instance - relatively slow weight gain may be normal.  Parents should always discuss a slow rate of weight gain with their physician.
