Does IBS Benefit From Low-Fodmap Diets?


The food you eat has a significant impact on your health, and digestive issues are extremely frequent.

Specific foods, such as wheat and beans, contain carbohydrates known as FODMAPs. Gas, bloating, stomach pain, diarrhea, and constipation are just some of the digestive symptoms that have been found to be strongly linked to FODMAPs.

Many people who suffer from common digestive issues can see surprising improvement on low FODMAP diets.

To understand the goodness of the FODMAP diet for IBS, its necessary to define IBS.

What is IBS?

The term “functional gastrointestinal disorders” (FGIDs) refers to a category of illnesses that includes irritable bowel syndrome (IBS). This means that they disrupt digestive function but lack the telltale signs of another disorder, such as ulcers, inflammation, tissue thickening, lumps, and bumps, or abnormal blood tests. 

Diagnosis of irritable bowel syndrome is based on the presence and severity of symptoms, as well as other factors such as how long the symptoms have been present and when they first appeared. It is advisable to consult with your gastro doctor in case of any Issues.

What are FODMAPs?

Fermentable. All of these items are fermented by bacteria in your digestive tract, producing gases.

  • Oligosaccharides. Prebiotics are a type of soluble plant fiber that provides food for the good bacteria already present in your digestive tract. Onions, garlic, beans, lentils, and a wide variety of wheat products all contain oligosaccharides. Non-celiac gluten sensitivity may in part be explained by sensitivity to oligosaccharides. People who believe they are gluten intolerant may actually be sensitive to the oligosaccharides found in wheat products, as these grains contain more fermentable sugars than their gluten-free counterparts.
  • Disaccharides. The fermentable sugar in this class is lactose, found naturally in both cow’s milk and human breast milk. Worldwide, lactose sensitivity ranks among the most frequent dietary restrictions.
  • Monosaccharides. The fruit sugar fructose is the fermentable sugar here. Nonetheless, this only occurs in specific ratios and concentrations, so not all fruits are harmed.
  • Polyols. Sugar alcohols are a type of artificial sweetener that is widely used. Some fruits naturally contain them as well.

FODMAPs and their effects.

Foods high in fermentable oligosaccharides and monosaccharides (FODMAPs) are common and often well tolerated by the general population. Due to their capacity to absorb water, FODMAPs travel slowly through the small intestine after being consumed. Once in the large intestine, the FODMAPs are fermented by gut bacteria and used as fuel. In a short amount of time, the bacteria convert the FODMAPs into gas.

The advantages of a low-FODMAP diet

High FODMAP foods are avoided on a low FODMAP diet. The available research suggests that this diet plan may help IBS patients.

People with irritable bowel syndrome (IBS) have been the primary focus of research on the low FODMAP diet. Symptoms of this frequent gastrointestinal illness include:

  • gas
  • bloating
  • Diarrhea
  • constipation

Approximately 20% of the population in the US suffers from IBS, with the vast majority going untreated.

Though the precise reason why some people experience IBS is unknown, it is common knowledge that changes in food can have a major impact on the condition. The effects of stress might also be significant.

About 75% of persons with IBS can benefit from a low FODMAP diet, according to certain studies.

They often report significant improvements in symptoms and quality of life.

Other digestive issues that fall under the umbrella category of “functional gastrointestinal disorders” (FGID) may also benefit from adhering to a low FODMAP diet. Possible benefits of a low FODMAP diet for those with intolerances include reduced bloating and constipation.

  • less bloating
  • less watery stools and fewer hard stools
  • relieved stomach ache
  • Mood problems like anxiety and sadness have been related to digestive difficulties, thus treating them may have favorable psychological effects as well.

Foods to include

  • Meals that are low in FODMAPs, which can be consumed more freely than foods that are medium or high in FODMAPs, include:
  • Lettuce, carrots, chives, fennel, eggplant, broccoli (stalks or florets), zucchini, green beans, and baby spinach are all examples of vegetables.
  • Among the fruit options are kiwis, grapes, oranges, cucumbers, and strawberries.
  • Various types of meat include poultry, pork, beef, lamb, and eggs, as well as tofu and deli meats.
  • Among the fish options, there are crab, lobster, salmon, tuna, and shrimp.
  • Ingredients high in fat include oils, sesame seeds, butter, almonds, macadamias, and walnuts.
  • Tubers, amaranth, millet, brown rice, corn tortillas, popcorn, and other grain products.

High FODMAP foods to avoid or limit

In terms of vegetables, you can’t go wrong with garlic, asparagus, onions, mushrooms, beans, shallots, and scallions.

  • Blackberries, watermelons, prunes, peaches, dates, and avocados are all examples of fruits that you can eat.
  • Meats: Garlic- and onion-based sauces and stuffings, as well as breaded and battered meats.
  • Fish: fried, breaded, and battered varieties, as well as fish prepared with garlicky or oniony sauces.
  • Nuts and avocados are good sources of fat.
  • Beans, lentils, wheat and allergen bread, rye, buns, pastries, and pasta all count as grains and starches.

It can be easier to add low-FODMAP foods to a diet if one is aware of the distinction between high and low-FODMAP meals. There is a great diversity of foodstuffs in both sets.


The symptoms of IBS and other digestive disorders may subside while following a low FODMAP diet. But its efficacy may hinge on a variety of factors, such as the severity of the symptoms and the degree to which the diet is followed.

It is recommended that anybody considering adopting a low FODMAP diet discuss the potential advantages and disadvantages with the best gastroenterologist in Lahore.


1. What is the success rate of the Fodmap diet?

Most people with IBS see improvement while following a low FODMAP diet, but not everyone. In reality, studies have shown that during phase 1 of the diet, between 50 and 80% of patients will notice a reduction in their IBS symptoms, leaving 20 to 50% of patients who do not respond to the diet.

2. How does IBS affect your daily life?

Life quality is often severely compromised in those with moderate to severe IBS. Studies show that those who suffer from IBS take three times as many sick days as those who do not because of their condition. Depression and other mood disorders. Living with IBS symptoms might put a person in a vulnerable mental state.

3. Why do some people have adverse reactions to FODMAPs?

The good bacteria in the colon ferment the FODMAPs when they get there. As gas is produced during fermentation, it strains the intestinal lining. If you have a weak digestive system, you may experience discomfort in the form of gas and bloating.
