Which Situations Trigger IBS?

IBS can be triggered by many situations like;

Age, IBS occurs most frequently between 20-50.

Gender, Women are twice as likely to have IBS, because of the hormonal changes. Many women find that signs and symptoms are worse during or around their menstrual periods.

Food sensitivities, Some foods like dairy, gluten, fruits, and grains can trigger IBS.

Medications, Drugs like antibiotics, and those made with sorbitol may worsen IBS.

Stress, While stress may aggravate symptoms, it doesn’t cause them.

Anxiety, Depression, and other mental health issues are also associated with IBS. A history of traumatic events like sexual, physical, or emotional abuse also might be a risk factor.

How to Decrease IBS Symptoms

The etiology of irritable bowel syndrome is thought to be multifactorial, with several factors like alterations in gut motility, small-bowel bacterial overgrowth, microscopic inflammation, visceral hypersensitivity and changes related to the brain-gut axis.

Diet is one way people manage IBS symptoms. A common treatment approach is to avoid the foods that trigger symptoms, depending on the type of IBS that you have. There are also various other treatment methods like stress management, medication, behavioral therapy, and alternative treatments.

Potential IBS Triggers

These foods are potential triggers of IBS. Triggers may be different for each person.

  • Vegetables and legumes – like onions, garlic, chickpeas, lentils, kidney beans
  • Fresh fruits such as apples, pears, peaches, cherries, mangoes, pears, and watermelon. Having three and more portions of fruit per day can trigger your IBS.
  • Grains – like wheat and rye
  • Added fiber – such as inulin (found in asparagus, onion, garlic)
  • Vegetables causing bloat and gas – like cabbage, broccoli and cauliflower
  • Gluten – Research shows that some people with IBS report improvement in diarrhea symptoms if they stop eating gluten (wheat, barley, and rye) even if they don’t have celiac disease.
  • Dairy – foods containing lactose such as cow’s milk, cheese, yogurt, and ice-cream
  • Sorbitol – an artificial sweetener found in some sugar-free sweets and drinks
  • Tea and coffee – also trigger IBS symptoms
  • Alcohol and carbonated drinks

Keeping a food journal is a great way to learn which foods and drinks trigger your symptoms.


Foods That Improve IBS

Studies have shown that a low FODMAP diet may improve IBS symptoms. FODMAP stands for “Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols. Researchers discovered that the small intestine does not absorb FODMAPs very well. They increase the amount of fluid in the bowel and create more gas because they are easily fermented by colonic bacteria. The increased fluid and gas in the bowel leads to bloating and changes in the speed with which food is digested. This results in gas, pain, and diarrhea. Eating less of these types of carbohydrates should decrease these symptoms.

One study even found that 76% of IBS patients following a  low FODMAP diet reported improvement with their symptoms. These low FODMAP foods are;

  • Lactose-free dairy -lactose-free milk and yogurt, such as rice milk, almond milk, coconut milk, and coconut yogurt
  • Fruit -like b Bananas, blueberries, grapefruit, kiwi, lemon, lime, oranges, and strawberries
  • Vegetables -such as carrots, cucumbers, eggplant, lettuce, zucchini, and potatoes
  • Protein -like beef, pork, chicken, fish, and eggs
  • Nuts/seeds -such as almonds, macadamia nuts, peanuts, pine nuts, and walnuts
  • Grains -like oats, oat bran, rice bran, gluten-free pasta, such as rice, corn, quinoa, white rice, cornflour, and quinoa

Probiotics are defined as “live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host.’’ They have positive effects on intestinal motility, sensitivity, and pain relief in IBS patients. But additional issues, such as the most effective probiotic strain, dose, and duration of therapy still need to be determined. 

The Bottom Line

Certain foods and diets like low FODMAP can help IBS, but everyone is different. Start to keep a food journal and examine which foods and situations trigger your IBS. If needed, talk to your doctor before starting a new diet. In addition, drink plenty of water, exercise regularly, and decrease your caffeine intake to promote regularity and minimize IBS symptoms.
