It is usually caused by a protein intolerance and will improve with the treatment of changing to a soy formula. Some babies will also have an intolerance to soy protein and may need to be on an elemental formula, such as Nutramagen or Alimentum.
Breast fed babies can also develop allergic colitis, usually secondary to maternal milk drinking.
Eliminating milk and other dairy products from the mother's diet is usually necessary, but you can continue to breast feed. Babies with allergic colitis should be seen by their doctor, especially if they have poor weight gain, vomiting, or abdominal pain. All rights reserved.
