Allergic Colitis

What is allergic colitis?

Allergic colitis is a condition in which your baby's immune system overreacts to the proteins found in cow's milk, leading to inflammation in the colon.

Babies differ in how sensitive they are to milk. Some have very few symptoms, and others might experience blood in the stools if a breast-feeding mother has even a small splash of milk in her morning coffee.

Allergic colitis isn't uncommon it affects between two and 3 percent of infants. Babies from families with a history of food allergies, asthma or environmental allergies seem to have a slightly higher risk of developing the condition.

Allergic colitis often has few symptoms, but may be associated with irritability, gassiness, and with blood or mucus in the stools can make eating very uncomfortable for a baby, so they may not get the nutrition they need.
