Yes, allergies can contribute to constipation in some cases. While not a direct cause-and-effect relationship for everyone, there's a link between allergic reactions and digestive issues, including constipation.
Mechanisms Linking Allergies and Constipation
Several mechanisms explain this connection:
-
Inflammation: Allergic reactions trigger inflammation throughout the body. In the digestive tract, this inflammation can affect the bowel's motility (movement), leading to slower transit time and constipation. This is particularly notable in conditions like eosinophilic esophagitis and proctitis, where eosinophilic infiltration (a type of inflammatory cell) impacts the esophageal and rectal walls, respectively, causing dysmotility. [Mechanisms relating constipation to allergy are dysmotility and changes in the mucus composition caused by inflammation of the rectal wall by an eosinophilic infiltration. A similar phenomenon of dysmotility caused by inflammation and eosinophilic infiltration can be observed in eosinophilic esophagitis.]
-
Increased Anal Sphincter Pressure: In children, allergic reactions can sometimes increase anal sphincter pressure, making bowel movements difficult. [The causes of allergic exacerbation of constipation in children are mostly related to increased anal sphincter pressure and intestinal...]
-
Food Allergies and Intolerances: Specific food allergies or intolerances can directly impact bowel function. For instance, a cow's milk allergy is linked to constipation in some children. [Food allergies, particularly to cow's milk, can cause constipation. A food history was required, and if the kid was still being nursed, the...] Food allergies or intolerances can also exacerbate existing constipation.

-
Dietary Restrictions: Managing food allergies often necessitates dietary restrictions, which may inadvertently lead to insufficient fiber intake, a known contributor to constipation.
Research and Studies
Studies have investigated the association between allergies and constipation. For example, research has examined the relationship between specific allergens and chronic constipation. [Association between 19 Allergens and Chronic Constipation in ...] Further research has explored the role of food allergy in pediatric constipation and the potential usefulness of atopy markers in diagnosis.

It's important to note that while a correlation exists, not all allergies cause constipation, and other factors often contribute to constipation.
Practical Considerations
If you suspect allergies are contributing to your constipation, consulting a doctor or allergist is essential for proper diagnosis and management. They can identify potential allergens and recommend appropriate treatment strategies.
