What Foods Can Trigger IBS?

What is IBS?  

IBS is a chronic digestive disorder characterized by bloating, gas, abdominal pain, and periodic bouts of constipation and diarrhea. IBS may be due to a combination of factors, but many people with the condition report that certain foods seem to trigger their symptoms. 

What Foods Can Trigger IBS? 

IBS does not affect everyone the same, and the foods that trigger the condition vary for each individual. Some of the most common problem foods include: 

  • Alcohol
  • Caffeine
  • Beans and legumes
  • Chocolate
  • Carbonated drinks
  • Artificial sweeteners

Dairy products such as cheese, ice cream, and milk are also IBS trigger foods. Choose non-dairy alternatives such as vegan cheese, sorbet, and almond milk instead.

Fried and fatty foods can also cause uncomfortable symptoms such as abdominal pain and cramping. Switch to grilled, broiled, or roasted food options and minimize the use of oil.   

Cruciferous vegetables such as broccoli, cabbage, and cauliflower can cause gas and bloating because they are difficult to digest. Vegetables like carrot, celery, and squash are better tolerated by people with IBS.  

Eating large meals can also make IBS worse as this can overstimulate the digestive system and lead to abdominal pain and cramping. Smaller meals will improve digestion and minimize symptoms.  

If you’re not sure which foods are causing IBS, keep a daily log of what you eat for at least one week. Recording how your body reacts to different foods will help pinpoint IBS triggers

Can Dietary Changes Reduce Symptoms of IBS? 

Trigger foods worsen IBS, so avoiding these will certainly ease symptoms of IBS. Once you know the problem foods, plan to avoid them to prevent flare-ups. 

Eating a healthy diet, getting regular exercise, and avoiding cigarettes can help keep the symptoms of IBS at bay. But depending on the cause of IBS, medication may also be necessary to reduce symptoms. At Cochise Oncology, our gastroenterologist uses a customized approach to treat IBS.
