Fibre Makes My IBS Worse

Do you struggle with irritable bowel syndrome (IBS) and find that your symptoms get worse when you eat more fibre? You’re not alone. Many people with IBS face the challenge of how fibre affects their gut health¹.

IBS is a chronic condition that affects 25 to 45 million people in the U.S¹. While fibre is good for gut health, some IBS patients find that certain fibres make their symptoms worse. This can lead to more bloating, constipation, or diarrhea¹. So, what’s the deal with fibre and IBS? Let’s explore this puzzling connection.

Key Takeaways

• Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder that affects millions of people.
• While fibre is generally recommended for gut health, some individuals with IBS find that increased fibre intake can worsen their symptoms.
• The relationship between fibre and IBS is complex, with different types of fibre having varying effects on IBS symptoms.
• Understanding the role of soluble vs. insoluble fibre, and fermentable vs. non-fermentable fibre, is key to managing IBS through dietary adjustments.
• Working with a dietitian can help IBS sufferers find the right balance of fibre to alleviate their symptoms and maintain overall gut health.

Understanding Irritable Bowel Syndrome (IBS)

IBS is a common issue that affects the large intestine². It brings on stomach pain, bloating, and changes in how often you go to the bathroom. These changes can include constipation, diarrhea, or both. The exact reason for IBS is still a mystery, but it seems to involve the gut, brain, and nerves working together.

What is IBS?

IBS is a condition that affects how the digestive system works². It’s not a problem with the structure or chemistry of the gut. People with IBS often face symptoms that really affect their life.

Prevalence and Impact of IBS

About 25-45 million people in the U.S. have IBS². This condition can really change someone’s daily life, leading to more doctor visits and less work done². Even though many people have it, IBS is often not well understood and can be hard to manage.

It’s important to understand what IBS is and what affects its symptoms. By looking into the causes and finding the right ways to manage it, people with IBS can feel better and live better.

The Role of Fibre in IBS

Dietary fibre is often suggested for people with irritable bowel syndrome (IBS). It helps regulate bowel function and boost gut health³. But, some folks might see their symptoms get worse with more fibre⁴.

Benefits of Fibre

Soluble fibre, like psyllium, makes stool softer and helps with constipation. Insoluble fibre, such as wheat bran, adds bulk to stool and eases diarrhea⁵. Studies show that fibre supplements, especially psyllium, can ease IBS symptoms better than a placebo⁵.

It’s wise to increase fibre slowly to let your gut adjust. A sudden jump can cause bloating⁵. Foods rich in fibre include fruits like raspberries and oranges, veggies like carrots and green beans, nuts like macadamias and almonds, and whole grains like quinoa flakes and brown rice³.

Soluble vs. Insoluble Fibre

Soluble fibre draws in water, which can ease diarrhea in IBS patients. Insoluble fibre, on the other hand, makes stool bulkier and helps with constipation⁵. Yet, some fibres like inulin, fructo-oligosaccharides (FOS), and pectin might cause problems for IBS sufferers due to gas and fermentation by-products³.

When picking bread and cereals, look at the fibre content per 100g to find ones with more fibre³. Supplements might not be as good as whole foods because they lack nutrients and biochemicals. Be cautious with “added fibre” foods as their benefits are not fully understood⁵.

“Gradually increasing fiber intake is recommended to give the bowel time to adjust.”

Fibre Makes My IBS Worse

For some people with irritable bowel syndrome (IBS), eating more fiber can make their symptoms worse⁶. This happens because some fibers are hard for the body to digest, leading to gas, bloating, and discomfort⁶. Foods high in insoluble fiber, like wheat bran, can also make IBS worse by irritating the gut⁶.

Some foods can trigger IBS diarrhea, such as fried foods, fatty foods, and dairy products, especially for those who are lactose intolerant⁶. Foods that can make IBS constipation worse include processed snacks, refined grains, and certain cheeses⁶. Other foods that can worsen IBS symptoms include chocolate, carbonated drinks, caffeine, and alcohol⁶.

To manage IBS symptoms, it’s advised to eat soluble fiber instead of insoluble fiber⁶. Foods rich in soluble fiber like oats, avocados, and sweet potatoes can help with constipation without causing discomfort⁶. Making lifestyle changes, such as eating smaller meals and reducing stress, can also help⁶.

If IBS symptoms are severe, it’s important to see a gastroenterologist for further advice⁶.

“The recommendation for managing IBS symptoms includes consuming soluble fiber instead of insoluble fiber to ease constipation without causing bloating or diarrhea.”

The daily fiber intake recommended for adults is 25-38 grams, with women aiming for 25 grams and men for 38 grams⁷. However, most adults only get about 15 grams of fiber daily, which is a big shortfall⁷. To meet the fiber goal, it’s suggested to include fiber-rich foods in every meal and snack⁷.

Soluble fibers like oats and beans can help with IBS-D symptoms by making stools bulkier and reducing diarrhea⁷. Psyllium husk fiber supplements are also effective for chronic constipation and can lessen IBS symptoms⁷.

About 10% to 15% of people in the U.S. have IBS⁸. Soluble fiber is found in foods like oat bran and nuts, while insoluble fiber is in wheat bran and vegetables⁸. Research from 2019 shows that a low FODMAP diet can help manage IBS symptoms⁸.

Fermentable vs. Non-Fermentable Fibre

For people with irritable bowel syndrome (IBS), the kind of fiber you eat is key. Fibers are either fermentable or non-fermentable, which matters a lot for IBS sufferers⁹.

Understanding Fermentation

Fermentable fibers, like inulin and fructo-oligosaccharides (FOS), get broken down by gut bacteria quickly. This process creates gas and other substances that can make IBS worse⁹. Non-fermentable fibers, such as cellulose, are less likely to cause these issues⁹.

The Low-FODMAP Diet

The low-FODMAP diet limits fermentable carbs and helps manage IBS symptoms¹⁰. It helps find and avoid the fibers that trigger IBS, helping you find what works best for you.

Choosing the right fiber supplements is important. Some supplements, like those with wheat bran, FOS, and GOS, can cause a lot of gas and worsen IBS symptoms⁹. But, options like psyllium, linseeds, oats, sterculia, and methylcellulose are often easier on people with IBS because they don’t cause as much gas⁹.

Early studies suggest that partially hydrolyzed guar gum (PHGG) might help with both constipation and diarrhea-type IBS. It also seems to have prebiotic effects⁹. Yet, ‘wheat dextrin’ fiber supplements haven’t been studied much for IBS⁹.

When starting fiber supplements, start with a small amount and slowly increase it over a few days⁹. It’s a good idea to talk to a healthcare expert, like a dietitian, GP, or gastroenterologist, for advice on the best fiber supplements for your needs⁹.

“Fiber supplements with wheat bran, FOS, and GOS can cause a lot of gas in the gut, making IBS symptoms worse in some people.”⁹

Incorporating Fibre on a Low-FODMAP Diet

Getting enough fibre on a low-FODMAP diet for irritable bowel syndrome (IBS) can be tough. Many high-fibre foods are also high in fermentable carbs, which can make IBS worse¹¹. But, with some planning, you can add low-FODMAP, high-fibre foods to your diet. This helps you get your daily fibre and supports your gut health.

Low-FODMAP, High-Fibre Foods

Here are some low-FODMAP, high-fibre foods you can eat:

• Quinoa¹¹
• Oats¹¹
• Certain nuts and seeds, such as almonds and chia seeds¹¹
• Limited portions of lentils and chickpeas, with proper rinsing to reduce FODMAP content¹¹

Controlling how much you eat and how you prepare foods, like rinsing canned legumes, can help. This way, you get fibre benefits without making your IBS worse¹¹. By adding these low-FODMAP, high-fibre foods, you can keep your diet balanced and support your gut health¹².

“Following a low FODMAP diet may help certain individuals with IBS, but it may lead to a lower intake of fiber-rich foods. It is recommended to aim for 30g of fiber per day, even when following a low FODMAP diet.”¹²

Tips for Achieving Adequate Fibre Intake

For people with Irritable Bowel Syndrome (IBS), getting enough fibre is key. It helps with symptoms like constipation, diarrhea, and bloating¹³. But, finding the right amount of fibre can be hard for those with IBS.

Here are some easy tips to help you get enough fibre:

• Eat high-fibre fruits and veggies like berries, citrus fruits, leafy greens, and beans every day¹³.
• Choose whole-grain breads, cereals, and pasta to increase your fibre intake¹⁴.
• Add seeds like chia, flax, or psyllium to smoothies, yogurt, or oatmeal¹³¹⁴.
• Go for low-FODMAP, high-fibre foods like potatoes, carrots, and okra to help with IBS symptoms¹³.

The daily fibre goal is 25-38 grams, but IBS patients might need less or more to feel good¹⁴. A dietitian can help you find the right fibre amount for your needs and IBS.

“Gradually increasing your fibre intake and staying hydrated can make a significant difference in managing IBS symptoms.”

Readily Fermentable Fibres

If you have irritable bowel syndrome (IBS), be careful with certain fibers. These include inulin, fructo-oligosaccharides (FOS), and pectin. They’re often in processed foods to increase fiber¹⁵. These fibers ferment quickly in the gut, causing gas, bloating, and discomfort for IBS sufferers¹⁵.

Studies show that dietary β-fructan fibers can cause inflammation in some IBD patients¹⁵. This could lead to better nutrition advice for those with IBD¹⁵.

Be aware of the fibers you eat if you have IBS. Soluble fibers like dietary β-fructan fibers can make you feel fuller longer¹⁵. But, they might cause bad symptoms for some with IBS¹⁵.

Knowing about readily fermentable fibers can help you choose better foods for your diet¹⁵. Researchers are even working on a stool test to match diets with IBS patients’ needs¹⁵.

Remember, everyone’s body reacts differently to foods¹⁶. It’s key to watch your symptoms and work with a healthcare pro for the best diet plan¹⁶.

Getting the Right Balance

Finding the right balance of fiber is key for those with Irritable Bowel Syndrome (IBS). Fiber is good for gut health, but the type and amount matter a lot for IBS sufferers¹⁷. A dietitian who knows about gut health can help you find the right fiber for you. They’ll make a plan that fits your needs for better symptom control.

Working with a Dietitian

A dietitian can be a big help in finding the best fiber mix for your IBS. They’ll guide you on using soluble and insoluble fibers¹⁷. They’ll suggest foods and supplements that are easy on your stomach¹⁸. With their help, you can adjust your fiber intake to help your digestive system without causing problems.

You and your dietitian can work on adding more fiber slowly¹⁷. They’ll make sure you drink enough water and watch for any bad reactions¹⁸. This teamwork can lead to the best fiber levels for your gut health and IBS symptoms.

“With the right guidance from a dietitian, I was able to find the perfect fiber balance to manage my IBS and improve my overall digestive health.”

Managing Fibre Intolerance in IBS

If you have irritable bowel syndrome (IBS) and fiber makes your symptoms worse, managing fiber is key¹⁹. Start by adding 2 to 3 grams of fiber to your diet each day. Aim for 25 grams a day for women and 38 grams for men¹⁹. Eating foods like whole wheat bread, oats, barley, and fruits can also help¹⁹.

Stay away from hard-to-digest fibers like beans, Brussels sprouts, and wheat germ to reduce bloating and gas¹⁹. Regular exercise of at least 30 minutes a day can also help prevent constipation and reduce stress¹⁹. Working with a healthcare provider and keeping a food diary can help you find out what foods trigger your symptoms¹⁹.

The low-FODMAP diet can be a big help if you’re struggling with fiber intolerance²⁰. It can help up to 75% of people with IBS feel better²⁰. Also, try lactose-free dairy and avoid coffee to manage your symptoms better²⁰.

Finding the right balance of fiber with IBS is a personal journey. Work with a healthcare professional and listen to your body to manage your symptoms and improve your health.

“Up to 3 out of 4 people find relief from abdominal pain, constipation, diarrhea, and bloating through a low FODMAP diet.”²⁰

Conclusion

The link between dietary fiber and irritable bowel syndrome (IBS) is complex. Fiber is good for gut health, but it can make IBS worse for some people²¹. This is especially true for certain types of fermentable fibers.

For people with IBS, finding the right fiber balance is key. A registered dietitian can help create a personalized fiber plan. This plan might include choosing specific fibers that are easier to digest, controlling how much fiber you eat, and using low-FODMAP fiber sources²².

Remember, not everyone with IBS reacts the same way to fiber. Working with a healthcare professional is vital for managing your symptoms. By tailoring your fiber intake, you can improve your gut health and feel better.
