Colitis-Diet Elimination


Also known as ‘Allergic Colitis,’ Cow’s Milk Protein Allergy affects 2-3% of infants. Your baby’s immune system overreacts to the protein in cow’s milk causing inflammation in their colon. Often this leads to blood in your infants stool. Other symptoms may include a very fussy or uncomfortable baby, especially when feeding, as well as a possible lack of weight gain. Sometimes other allergic symptoms may be present, such as severe eczema.

It is unknown what exactly causes Allergic Colitis, there may be a hereditary component, as babies who come from a family with a history of food allergies, asthma or environmental allergies seem to be more likely to have allergic colitis.

Treatment of Allergic Colitis is the removal of milk protein from your infant’s diet. This will be done either by switching your baby to a hypoallergenic formula (such as Alimentum or Nutramigen) or having the mother go on a dairy-free diet if she wishes to continue to breastfeed. 30% of infants who are allergic to milk protein are also allergic to soy; therefore, your provider may suggest a soy-free diet as well.

It may take up to 72 hours for breast milk to become free of milk protein. Your provider may suggest using a hypoallergenic formula during this time period. It will take several weeks for your infant’s intestines to heal; therefore, you may see blood in the stool for this amount of time. However, your baby should be feeling better; less irritable, less reluctant to feed & may even be putting on weight. You will continue to follow-up in the office to assess for this improvement.

Allergic Colitis is different than a true milk allergy. Most babies outgrow the milk protein allergy by the time they’re one year old. Your provider will discuss with you introducing cow’s milk around this age.
