What diet should a person use with IBS?


Dear Dietitian,

I was recently hospitalized overnight for irritable bowel syndrome. The abdominal pain was treated, then I was released the following day. I was not given any information on what diet I should follow. Can you help?


Dear Julie,

A flare-up of irritable bowel syndrome (IBS) can be very painful, but the good news is it can be well-managed with diet and lifestyle changes. IBS is a common intestinal disorder that affects 25-45 million Americans. It requires a diagnosis by a physician or another qualified clinician. The cause of IBS is unclear; it is usually diagnosed based on symptoms. This condition can cause abdominal pain, gas, bloating, constipation and diarrhea.

During a flare-up of IBS, avoid high-fiber foods – fresh fruits and vegetables and whole grains. When the flare subsides, you may slowly add these foods back into your diet. Many research studies point to a high-fiber diet to help prevent obesity, heart disease, diabetes, and possibly some types of cancer. It is essential to add these foods to your diet. Most Americans get about half the recommended amount of fiber each day, so if your body is not used to high-fiber foods, increase intake slowly. Start with 5 grams of fiber each day, and increase by 5 grams each week until you reach a goal of 25-35 grams per day. Drink plenty of water and noncaffeinated beverages while increasing fiber intake.

In today’s busy world, sometimes we don’t find enough time to slow down and eat at regular times. As we have daily routines, mealtimes should also be a part of that routine. This way, food will be moving through your system regularly. In addition, planned meals tend to be healthier, and you will be less likely to grab fast food on the run, which is often high in fat.

Stress is a part of everyday life, and it’s essential to manage stress when managing IBS. Increasing physical activity, yoga, stretching, breathing exercises, and meditation can alleviate pressure from life’s twists and turns.

Knowing what foods your body can comfortably digest is essential when managing IBS. Many people have trouble tolerating sugar alcohols. These are found in some sugar-free products and are commonly known as xylitol, sorbitol, and mannitol. The amount of these artificial sweeteners found in sugar-free gum probably won’t have negative consequences, but avoid large amounts since they can cause excessive gas and abdominal discomfort.

Finally, while certain foods do not cause IBS, some find that specific foods irritate the condition. Keep a record of these foods so that you remember to avoid them next time. Just carry a pocket-size notebook and record problem foods as you go about your week.

Until next time, be healthy!
