What are the Symptoms of Allergic Proctocolitis?

The main symptom of Allergic Proctocolitis (AP) is mucus with visible specks or streaks of blood in dirty diapers (stools). The stools may be watery, and they are often green. Many infants with AP are very fussy. It is not uncommon for families to be told their baby has colic. Bouts of crying (day and night), poor sleep, and obvious discomfort after eating can be a part of AP too. Some babies with AP have skin rashes or eczema, although these are more common with other kinds of allergic reactions.

If you don’t see any blood, but there is mucus and misery, your doctor can test a sample of stool to see if there is invisible (occult) blood. AP usually shows up in the first 2 months of life.

Babies with Allergic Proctocolitis DO NOT throw up regularly, and they don’t have a lot of diarrhea. They grow and develop normally and don’t show signs of malnutrition. More serious symptoms could be caused by a different kind of food allergy, or another medical issue. It is important that you let a health care provider know what is going on.
