👉 Pericolitis is a medical condition that occurs when the body's immune system mistakenly attacks its own tissues, leading to inflammation. In this case, it can be defined as an allergic reaction that affects the digestive tract, causing symptoms such as abdominal pain, nausea, vomiting, diarrhea, and fever. It is often associated with food allergies or other sensitivities to certain foods, which can trigger a response in the body's immune system.
