IBS (Irritable Bowel Syndrome) Triggers and Prevention
Irritable Bowel Syndrome (IBS) Triggers and Prevention Overview
The exact role of food intolerance in irritable bowel syndrome (IBS) is not clearly understood. It is known that many people have more severe symptoms depending on their dietary intake of certain foods. An elimination diet (slowly eliminating foods from the diet, and noting any IBS symptom changes) may be helpful for some individuals with IBS to learn what foods trigger IBS symptoms, and what foods prevent triggers. Discuss any dietary changes with your healthcare professional.
Diet Triggers for IBS causing Constipation or Diarrhea

Many people suffering from IBS note very specific trigger foods that worsen their symptoms. The individual usually learns what trigger foods to avoid. Food diaries can be helpful in pinpointing the products causing a worsening of symptoms. People with IBS usually suffer both from diarrhea and constipation and different foods are often implicated as triggers.
IBS Diet and Diarrhea
IBS Diet and Constipation
As with all food intake, some foods might be tolerated in moderation but cause symptoms if ingested in excess.
One suggested approach is to remove a food or food category, watch and note symptoms, and slowly reintroduce the food back into the diet and track your symptoms (elimination diet).
Fiber products can help (in case of constipation) or worsen IBS (diarrhea).
