The influence of diet is unique to each person. There is no generalized dietary advice that will work for everyone.
A physician can take a brief dietary history and help identify dietary and/or other factors that may impact symptoms. Keeping a diary for 2–3 weeks of dietary intake, symptoms, and any associated factors (like daily obligations, stressors, poor sleep, medications) can help with this.
For those with irritable bowel syndrome (IBS) who benefit from simple dietary modifications, it makes sense to adjust the diet and reduce intake of the offending food. It does not make sense to adopt unnecessarily limited diets. This can lead to reduced quality of life or even malnutrition.
Doctors and patients need to talk about diet. Guidance needs to be provided by a knowledgeable health care professional (like a physician or registered dietician). They can assess individual circumstances affecting IBS, while helping make sure that nutritional needs are being met through a balanced diet, and healthy eating habits.
Tips for an IBS-Friendly Diet
Meals may seem to trigger symptoms. It may be the process of eating and not a certain food that sets off your symptoms. Eating stimulates the digestive tract, which can over-respond because of IBS.
- Try eating smaller meals, more often, spread throughout your day. Instead of 3 meals, try 5 or 6 regularly scheduled small meals.
- Slow down; don't rush through meals.
- Avoid meals that over-stimulate everyone's gut, like large meals or high fat foods.
- If you are constipated, try to make sure you have breakfast, as this is the meal that is most likely to stimulate the colon and give you a bowel movement.
If you think a certain food is a problem, try cutting it out of your diet for about 12 weeks. (If you suspect more than one, cut out one at a time so you know which one causes you problems.) If there's no change, go back to eating it.
The foods most likely to cause problems are:
- Insoluble (cereal) fiber
Be sure to eat a healthy diet. If food is a major problem for you, talk to your doctor or a registered dietician to work out a meal plan that's best for you.
