From the Guidelines
For people with ulcerative colitis, the best stool bulking agents are generally psyllium (Metamucil) and methylcellulose (Citrucel). These soluble fiber supplements can help manage both constipation and diarrhea by absorbing water and forming a gel-like substance that adds bulk to stool. Start with a low dose of 1 teaspoon mixed in 8 ounces of water once daily, gradually increasing to 1-2 tablespoons 1-3 times daily as tolerated. Take these supplements with plenty of water and separate from medications by at least 2 hours. During flare-ups, it's best to avoid bulking agents as they may worsen symptoms. Psyllium is derived from plant husks and can sometimes cause gas, while methylcellulose is synthetic and typically produces less gas, making it potentially better for those with sensitive digestive systems. Insoluble fiber supplements like wheat bran should be avoided during active colitis as they can irritate the inflamed colon. Always consult with your gastroenterologist before starting any supplement, as individual needs vary based on disease activity and symptoms.
Key Considerations
- The use of stool bulking agents should be individualized based on the patient's specific needs and disease activity.
- Patients with proximal constipation should be treated with stool bulking agents or laxatives, as recommended by guidelines 1.
- The choice of stool bulking agent should take into account the patient's tolerance and potential side effects, such as gas and bloating.
- The management of ulcerative colitis should prioritize the reduction of morbidity, mortality, and improvement of quality of life, with the use of stool bulking agents being one aspect of overall disease management.
Recommendations
- Start with a low dose of psyllium or methylcellulose and gradually increase as tolerated.
- Take stool bulking agents with plenty of water and separate from medications by at least 2 hours.
- Avoid insoluble fiber supplements like wheat bran during active colitis.
- Consult with a gastroenterologist before starting any supplement to determine the best course of treatment for individual needs.

- Methylcellulose 4 These are all bulk-forming agents, which can help manage stool consistency. However, it is essential to consult a doctor before use, especially if symptoms like abdominal pain, nausea, or vomiting are present 3.
From the Research
Stool Bulking Agents for Ulcerative Colitis
There is limited information available on the best stool bulking agents for people with ulcerative colitis.
- The provided studies focus on the diagnosis, treatment, and management of ulcerative colitis, but do not specifically discuss stool bulking agents 5, 6, 7, 8, 9.
- One study mentions the importance of nutrition and supplementation in ulcerative colitis, highlighting the potential benefits of certain dietary components, such as omega-3 fatty acids and probiotics, but does not address stool bulking agents directly 7.
- Another study discusses the use of fecal calprotectin as a noninvasive marker of disease activity in ulcerative colitis, but does not provide information on stool bulking agents 8.
Dietary Considerations
While there is no specific information on stool bulking agents, the studies suggest that dietary considerations may play a role in managing ulcerative colitis.
- The Mediterranean diet has shown promising results in the treatment of patients with ulcerative colitis due to its high content of biologically active foods 7.
- Patients with ulcerative colitis may benefit from the UC Exclusion Diet (UCED), although further research is needed to confirm its effectiveness 7.
