The symptoms of consuming too much fiber can be reduced by:

  • Getting more exercise or physical activity
  • Lowering your fiber consumption
  • Avoiding the intake of high-fiber foods
  • Removing fiber-fortified foods from your diet
  • Eating a bland diet till the symptoms settle
  • Eating foods that contain substances like chicory root extract and inulin
  • Maintaining a diary of your food intake to note how much fiber you are eating every day
  • Following a low FODMAP diet if you have irritable bowel syndrome to improve symptoms as it removes fermentable and fibrous foods from your diet.

Once you start to feel better and your symptoms subside, you can slowly re-introduce fiber-containing foods into your diet. However, avoid eating fiber-rich foods all at one go in one meal. Instead, spread them out throughout the day to avoid having a surge of fiber in the body suddenly. It is also recommended to get your fiber from a variety of fiber-rich foods instead of relying on just one fiber source. Eating a wide variety of fruits and vegetables, beans, nuts, and whole grains will also give you more nutrition.

After consulting your doctor, you may choose to follow a diet low in fiber if you have severe symptoms. This means only eating around ten grams of fiber each day until the symptoms subside or can be better managed. This low-fiber diet is usually prescribed for people who have serious digestive conditions or have undergone some digestive procedures.

In Some Cases Eating More Fiber Makes Constipation Worse

In theory, fiber should help prevent and treat constipation.

However, the evidence shows that this advice does not work for everyone.

While some studies show that adding fiber to your diet may improve your symptoms, other studies show that reducing your intake is best .

Also, a recent review found that although fiber was effective at increasing the number of bowel movements, it didnt help with other symptoms of constipation like stool consistency, pain, bloating and gas .

To find out if increasing your fiber intake will help your constipation, try to determine its cause. You can become constipated for a number of reasons, including:

  • Lifestyle factors: Low dietary fiber intake, inactivity and low fluid intake.
  • Medications or supplements: Examples include opioid painkillers, antidepressants, antipsychotics and some antacids.
  • Disease: Examples include diabetes, irritable bowel syndrome, inflammatory bowel disease and neurological conditions like Parkinsons.
  • Unknown: The cause of some peoples chronic constipation is unknown. This is known as chronic idiopathic constipation.

If you already eat plenty of fiber and your constipation is caused by something else, then adding more fiber may not help and could even make the problem worse .

Interestingly, studies have shown that some people with constipation eat similar amounts of fiber as those who dont have the condition (

Control Blood Sugar Levels

As previously discussed, soluble fiber turns into a gel-like substance which can help to slow the absorption of nutrients. This includes sugar or carbohydrates. Which is useful in controlling blood sugar levels in individuals with diabetes.

A high fiber diet may also be beneficial in lowering your chance of developing type 2 diabetes.

Finding Relief From Ingesting Too Much Fiber

The following techniques can help you find relief from the symptoms of excessive ingestion.

  • Drink lots of water
  • Refrain intake of fibrous supplements
  • Stay away from high-fiber foods.
  • Avoid too spicy and flavored foods
  • Dont sit all day long, walk more often and add light physical activities to your daily routine
  • Take note of the amount of fiber you take each day

As soon as you get better, you can gradually start adding foods with fiber to your diet. But remember not to intake lots of fiber in a single meal, instead take small portions and evenly distribute them in several meals.

Getting fiber from different foods and not depending on any single one is the best approach. You can get fiber from beans, grains, nuts, fruits, and vegetables.

What Effects Does Fiber Have On Your Digestion

7 Problems Caused by Too Much Fiber (and the Signs and Symptoms)

The two main types of fiber that play a vital role in digestion are:

Insoluble fiber: It helps the food to pass in a quick manner through the intestines and stomach. Moreover, it makes your stool bulky. It also plays an essential part in balancing your intestines pH.

Soluble fiber: It is responsible for giving your food a gel-like form. This puts a brake on digestion and is the reason why you feel full . It can also alleviate the chances of heart disease and puts your blood sugar to a healthy level.

You’re Feeling Bloated Or Gassy

A little bloating and gas is normal when you eat a fiber-heavy meal, especially if it involves cruciferous veggies like cauliflower or Brussels sprouts, says dietitian Bonnie Taub-Dix, RD, author of âRead It Before You Eat It: Taking You from Label to Tableâ. But if your symptoms cause discomfort or disrupt your day-to-day, you may be overdoing it.

Fiber is a carbohydrate you can’t digest, according to the Harvard T.H. Chan School of Public Health. Instead, it goes through your body unprocessed. As a result, you can feel overly full or gassy as the nutrient moves through your system.

You may also have gas and bloating if you’re increasing your day-to-day fiber intake too quickly, Taub-Dix says â in other words, you can have too much fiber at once. While you may only be eating the recommended daily amount , going from 10 grams one day to 30 grams the next is likely to cause digestive issues.

The fix? Because you can eat too much fiber too fast, ease into it at first. Gradually work the nutrient into your diet over the course of a few weeks to give your body time to adjust, according to the Mayo Clinic.

How Much Fiber Should You Get Per Day

Thanks to some of today’s popular diet fads , most people aren’t actually eating enough fiber. But as you may have experienced firsthand, it’s also possible to eat too much fiber and have negative effects.

Generally, Americans eat about 10 to 15 grams of fiber per day, according to Harvard Health Publishing. Here’s a look at how much adults should actually be getting, broken down by age and sex:

A Word On Fiber Supplements

There isnt any evidence that taking daily fiber supplements is harmful, according to the Mayo Clinic. And if youre having trouble getting enough fiber in your diet for whatever reason, these pills and powders are a convenient way to help you close the gap, Young says. Its also great in a pinch if youre experiencing constipation, Dr. Lee says.

However, overloading on fiber too quickly is easier to do with supplements than whole foods, so the advice to start slow and drink enough water is especially important here to avoid side effects, Dr. Lee says. And since many supplements contain only soluble or insoluble fiber, youre not getting that balanced intake and regulation that you do with naturally fibrous foods, Young points out. Plus, some fiber supplements can interfere with the absorption of medications if you take them at a similar timeso take them at a different time of day from each other, and talk to your prescribing doctor before adding functional fiber to your diet. And definitely consult your doctor first if you have a GI condition.

The biggest overall drawback, though, is that if you rely on supplements to hit your fiber requirements, youre missing out on all the other nutrients found in the all-around healthy foods that naturally contain fiber, Young says. Plus, the real stuff just tastes so much better.

Duke University suggests removing sources of added fiber from your diet to relieve bloating and other symptoms of too much fiber. These may include high-fiber cereals and bars since they can be harder for your digestive system to handle than natural dietary fiber.

The experts at Duke University also advise taking a look at your meals. If all your meals have high-fiber components, switching out some of your grains and proteins for low-fiber options and eating more cooked food instead of raw food could help. You should also avoid other foods that cause bloating, like chewing gum, candy and cough drops.

According to the International Foundation for Gastrointestinal Disorders, adding too much fiber to your diet too quickly can be worse than being on a low-fiber diet. If you’re increasing your intake of fibrous foods, HMS advises doing it gradually to give your digestive system time to adjust to it.

It is also recommended that you increase your intake of water as you increase your intake of this nutrient, especially if you’re taking fiber supplements. Per the Cleveland Clinic, you should be drinking at least 8 ounces of liquid with fiber supplements. Taking certain fiber supplements without enough water may cause the fiber to swell, causing constipation and choking.

According to the Academy of Nutrition and Dietetics, high intakes of functional fiber may cause excessive flatulence, bloating and diarrhea. The fermentation of dietary fiber along with other undigested proteins and carbohydrates in your digestive system may also cause intestinal gas and other digestive issues.

Duke University notes that excess consumption of this nutrient may result in a lack of appetite as well as weight loss and the inability to build muscle because you’re unable to get enough energy or nutrition from your food. This is because fiber can bind to certain nutrients like iron, calcium, zinc and magnesium, and block their absorption by the body.

How Much Fiber Should You Have

While fiber is excellent for health, it is essential to consume the right amounts. Too much or too little can cause some uncomfortable digestive symptoms. The recommended daily amount of fiber is:

  • 21 to 25 grams of fiber a day for women
  • 30 to 38 grams of fiber a day for men

It is better to go a little over the recommended range than not have enough fiber. A little bit of excess fiber may increase your bowel size and frequency. Too little fiber, however, is likely to cause constipation.

Some experts estimate that as much as 95 percent of the population does not ingest enough fiber, with the average estimated at around 15 grams. This is why people so often recommend increasing your intake of dietary fiber.

If you already eat plenty of fiber-rich foods, however, you don’t have to worry about it. You could be consuming too much fiber. If you have too much fiber, it can also lead to some digestive issues, though keep in mind that this is far less common than not consuming enough fiber daily.

You May Be Eating Too Much Fiber If You Experience:

What Causes Constipation? Can Eating More Fiber Help? Dr.Berg

Bloating and abdominal pain

Flatulence, loose stools, or diarrhea

Constipation and weight gain

Yikes, yucky stuff, I know. But the good thing is its easy to turn it around! First, lets take a look at what fiber specifically is.

Dietary fiber is basically plant material that cannot be broken down in our digestive tracts. Fiber is either water-soluble or water-insoluble, but these are different in the following ways:

Soluble fibers absorb water during digestion. In turn, this adds bulk to stools, ideally making them easier to pass. Additionally, soluble fiber promotes healthy blood cholesterol levels and decreases the risk of developing diabetes or heart disease. Soluble fiber is found in fruits, vegetables, legumes, barley, and oats.

Insoluble fibers dont absorb water during digestion. Rather, they remain unchanged which can help facilitate movement of the intestines. Found in fruits with edible peels, vegetables, whole grains, bulgur, rolled oats, brown rice, and corn meal.

How Soluble Fiber May Aid Digestion

Accordingly, natural foods with soluble fiber, in particular, offer the advantage of slowing nutrient absorption.

In addition to improving satiety, they can reduce the blood sugar and insulin response induced by carbohydrates in natural foods.

With this in mind, a study administered the same amount of carbohydrates and calories to two groups of type 2 diabetics.

As a result, they found significantly lower blood glucose and insulin spikes in the group with a higher amount of fiber in their diet .

For example, beans and berries are foods that naturally contain soluble fiber.

Also, avocados represent an outstanding example because, in addition to soluble fiber, they contain hardly any carbohydrates and abundant electrolytes, vitamins, and healthy fatty acids.

Moreover, they help absorb fat-soluble nutrients from other foods.

Accordingly, one study found that the body absorbs about 3-5 times more antioxidants and carotenoids if avocados accompany salads .

Consequently, natural foods with dietary fiber occupy a valuable place in a healthy diet.

In contrast, highly processed foods often remove protective and useful factors such as dietary fiber or healthy fats.

With this in mind, we will deduce why supplementation with fiber might cause a more severe digestion issue based on further studies.
