Patients experience acute cramping, less often aching dull pain throughout the abdomen, accompanied by rumbling, bloating and pouring, as well as imperative urges to defecate. Frequent loose stools appear, often with an admixture of undigested food or mucus, less often blood. Sometimes mucous films may be released (membranous colitis, mucous colic). Coproscopic examination reveals signs of accelerated intestinal motor function, impaired digestion, intestinal hypersecretion, sometimes eosinophilia and Charcot-Leyden crystals.
In some cases, the clinical picture resembles acute appendicitis, intestinal obstruction, thrombosis of the mesenteric vessels. Colic abdominal pain and tenderness on palpation, fever, vomiting, constipation or, conversely, diarrhea, as well as tachycardia, a drop in blood pressure, leukocytosis in the blood allow us to suspect an abdominal catastrophe. However, the rapid effect of taking antiallergic drugs, the presence of general allergic symptoms (urticaria, Quincke's edema, bronchospasm, migraine, etc.) and a favorable outcome in most cases help to make the correct diagnosis. An alimentary allergic reaction can be repeated in the same patient when taking an intolerable product.
