What is Allergic Proctocolitis?

If my story sounds familiar, your baby may have Allergic Proctocolitis (also called Milk/Soy Protein Intolerance, Dietary Protein-Induced Proctocolitis, and many other complicated names!) Proctocolitis is inflammation of the lower part of the intestines. If the inflammation is caused by an allergic reaction, it is called Allergic Proctocolitis. Note: while this condition is often referred to as a food sensitivity, hypersensitivity reaction, or intolerance, it is, technically, an allergy.
