Gastric Function in Relation to Degree of Postprandial or Food Aggravation of Symptoms in Patients with IBS. Participants were subdivided by the number (0–3) of food related pain components: pain brought on by food; pain immediately after food ingestion within 0–30 min of meal; and pain experienced 30–120 minutes after the meal.
