Fiber supplementation, particularly psyllium, is both safe and effective in improving IBS symptoms globally. Dietary fiber also has other health benefits, such as lowering blood cholesterol levels, improving glycemic control and body weight management.
#1. Psyllium Husk Fiber. This fiber retains water and provides bulky, easy-to-pass soft stools. Psyllium has been shown to be more effective than stool softeners for those with chronic idiopathic constipation and is also touted as one of the “go to” fiber source for IBS.
Fiber Supplements for IBS
A recent study found that psyllium, a soluble fiber, provided significant pain relief for IBS patients with constipation and/or diarrhea.
For individuals with constipation-predominant IBS, a soluble fiber supplement (Metamucil or others containing psyllium) can be helpful. Large amounts of fiber can hinder the absorption of medications, so take your medications one to two hours before the fiber supplement.
Thus psyllium is beneficial in IBS through the microbial and neural route and by decreasing inflammation. Psyllium supplement at adequate dosage (at least 20-25 g per day) with adequate amount of water, coupled with other physiological steps could provide substantial relief in IBS.
Ask a doctor before using this medicine if you are pregnant or breastfeeding. Your dose needs may be different during pregnancy or while you are nursing. Do not give psyllium to a child younger than 6 years old without medical advice.
However, for some people with IBD, too much psyllium can make symptoms worse. Work closely with your doctor to decide how much fiber is right for you. Several studies have found that soluble fiber (including psyllium) helps relieve some symptoms of IBS, such as diarrhea and constipation.
Fiber can trigger IBS symptoms by setting off an overreaction to mechanical stimuli or by providing fodder for bacterial fermentation. But fiber, and especially soluble fiber, has been shown to ease overall symptoms and constipation in IBS sufferers.
Contraindicated in people with fecal impaction or gastrointestinal obstruction (bowel blockage). Some people are allergic to psyllium, and Metamucil should be stopped and emergency treatment sought if hives, difficulty breathing, or facial swelling occurs. Not suitable for children younger than six.
Fiber pill supplements or a powder mixture that contains psyllium (like Metamucil) can help some people with IBS control their diarrhea. "Some individuals may use a fiber preparation, which some people find useful to bind and increase the bulk of the stool for those who have diarrhea," recommends Gilinsky.
Foods that can make IBS-related diarrhea worse for some people include: Too much fiber, especially the insoluble kind you get in the skin of fruits and vegetables. Food and drinks with chocolate, alcohol, caffeine, fructose, or sorbitol.
Alosetron (Lotronex) or Lubiprostone (Amitiza) are two common IBS medications. Antispasmodics: These are designed to relax the smooth muscles of the colon to ease cramping and spasms. Two such medications are hyoscine (Levsin) and dicyclomine (Bentyl).
Probiotics may relieve symptoms of IBS
The American College of Gastroenterology conducted a meta-analysis of more than 30 studies, which found that probiotics may improve overall symptoms, as well as bloating and flatulence, in people with IBS.
Both soluble and insoluble fiber have their own benefits. Soluble fiber can help improve digestion and lower blood sugar, while insoluble fiber can soften stool, making it easier to pass.
Certain grains: Gluten-free oatmeal and brown rice are usually well-received by people with IBS and provide soluble fiber, which helps regulate bowel movements.
There's no evidence that daily use of fiber supplements — such as psyllium (Metamucil, Konsyl, others) or methylcellulose (Citrucel) — is harmful. Fiber has a number of health benefits, including normalizing bowel function and preventing constipation.
Benefits of Benefiber and Metamucil
People can increase their fiber by eating more high-fiber foods or introducing fiber supplements. Keeping the bowels moving regularly can improve gut health and relieve the symptoms of digestive conditions, such as irritable bowel syndrome (IBS) and diverticulosis.
Both psyllium powder and psyllium husk are high in dietary fiber, but the powder provides twice the amount. Psyllium seed powder has 7 grams of fiber per 1-tablespoon serving and the husk provides 3.5 grams per tablespoon.
One of the effects of psyllium is to slow your body's absorption of substances in your digestive tract. That includes many medications, notably some cholesterol drugs, tricyclic antidepressants, digoxin and blood thinners such as warfarin, which can be adversely affected by psyllium.
Any time of day is a great day to take Metamucil's psyllium husk, so long as you drink plenty of water with it (at least 8 oz). Start with one serving per day, then gradually increase your daily servings each week to reach your health goals.
Digestive distress: Psyllium fiber can create bloating, gas, abdominal discomfort, cramping (and even diarrhea) due to the fact that it bulks the stool. That's why it's incredibly important to drink plenty of water with it.
