Can constipation trigger an autoimmune disease flare?

From the Guidelines

Constipation can potentially trigger or worsen autoimmune flare-ups in some individuals, though the relationship is complex and not universal. The connection stems from the gut-immune system relationship, where constipation can increase intestinal permeability and alter the gut microbiome, potentially leading to increased inflammation and immune system activation 1. For those with autoimmune conditions, this inflammatory response may contribute to symptom flares.

Managing Constipation to Reduce Autoimmune Flare-ups

To mitigate this risk, several strategies can be employed:

• Adequate hydration: drinking 6-8 glasses of water daily
• Fiber intake: consuming 25-30g daily from fruits, vegetables, and whole grains
• Regular physical activity
• Establishing consistent bathroom routines Over-the-counter options like bulk forming laxatives such as unprocessed wheat bran, or osmotic laxatives like macrogols (polyethylene glycol) can help prevent constipation 1.

Treatment Options

If constipation persists, other treatment options include:

• Stimulant laxatives, which increase intestinal motility but should be avoided in intestinal obstruction
• 5HT 4 receptor agonists (prucalopride), which have prokinetic properties and are licensed for the treatment of chronic constipation in women when other laxatives have failed 1
• Linaclotide, a 14-amino acid peptide that acts in the intestinal lumen on guanylate cyclase-C (GC-C) 1

Personalized Management

If a pattern between constipation and autoimmune symptoms is noticed, tracking these occurrences and discussing them with a healthcare provider can help establish personalized management strategies for both conditions. This approach prioritizes reducing morbidity, mortality, and improving quality of life by addressing the complex relationship between constipation and autoimmune disease flare-ups 1.

From the Research

Constipation and Autoimmune Disease Flare

• Constipation is a common symptom in various autoimmune diseases, and its relationship with disease flare-ups is complex [ 2 ].
• Autoimmune diseases such as inflammatory bowel disease, rheumatologic diseases, and Hashimoto hypothyroidism can have gastrointestinal manifestations, including constipation [ 3, 2 ].
• The exact mechanism of how constipation triggers an autoimmune disease flare is not well understood, but it is thought to be related to the disruption of the intestinal barrier function and the imbalance of the gut microbiome [ 4 ].
• Studies have shown that patients with autoimmune diseases are more prone to gastrointestinal symptoms, including constipation, and that these symptoms can exacerbate disease activity [ 3, 5 ].

Gastrointestinal Manifestations in Autoimmune Diseases

• Autoimmune diseases can cause a wide range of gastrointestinal manifestations, including constipation, diarrhea, abdominal pain, and gastrointestinal bleeding [ 2 ].
• The gastrointestinal tract is a common site of involvement in autoimmune diseases, and the symptoms can vary depending on the underlying disease process [ 2 ].
• Constipation is a common symptom in autoimmune diseases, and its management is crucial to prevent disease flare-ups and improve quality of life [ 6 ].

Management of Constipation in Autoimmune Diseases

• The management of constipation in autoimmune diseases requires a comprehensive approach, including lifestyle modifications, dietary changes, and pharmacological interventions [ 6 ].
• Patients with autoimmune diseases should be monitored closely for gastrointestinal symptoms, including constipation, and treated promptly to prevent disease flare-ups [ 3 ].
• Further research is needed to understand the relationship between constipation and autoimmune disease flare-ups and to develop effective management strategies [ 4 ].
