Celiac disease is an autoimmune condition triggered by gluten, leading to small intestine damage. Heartburn is a burning sensation in the chest caused by stomach acid reflux. This article explores the potential relationship between celiac disease and heartburn, addressing how one might contribute to the other.
Understanding Celiac Disease
Celiac disease is an autoimmune disorder that affects the small intestine when gluten is consumed. In individuals with celiac disease, the immune system mistakenly attacks the body’s own tissues in response to gluten. This attack specifically targets the villi, which are tiny, finger-like projections lining the small intestine.
The villi are responsible for absorbing nutrients from digested food. When these villi are damaged, they flatten, significantly reducing the surface area available for nutrient absorption. This impairment can lead to various nutritional deficiencies and other health problems if the condition remains untreated.
How Celiac Disease Can Lead to Heartburn
Celiac disease can contribute to heartburn through several digestive system changes. The damage to the small intestine caused by gluten can impair nutrient absorption, leading to undigested food fermenting in the gut. This fermentation process can produce excess gas and pressure, which may then contribute to acid reflux and the sensation of heartburn.
Inflammation associated with active celiac disease can also impact gut motility. This systemic or localized inflammation may affect the function of the lower esophageal sphincter (LES), the muscle that prevents stomach acid from flowing back into the esophagus. A compromised LES can allow acid to reflux, causing heartburn.
Delayed gastric emptying, where food remains in the stomach longer, can increase acid reflux and heartburn. Celiac disease can also involve conditions such as small intestinal bacterial overgrowth (SIBO) or microscopic colitis, which independently cause digestive discomfort, including heartburn. Heartburn is thus a potential consequence of celiac disease’s broader effects, not a direct symptom of intestinal damage.
Addressing Heartburn with Celiac Disease
The primary approach to managing heartburn associated with celiac disease involves strict adherence to a gluten-free diet (GFD). Consistently avoiding gluten allows the damaged small intestine to heal over time. As the villi recover and normal intestinal function is restored, the underlying issues contributing to heartburn, such as malabsorption and inflammation, often improve.
Healing the small intestine can resolve or significantly reduce heartburn symptoms by normalizing gut motility and reducing excessive gas production. If heartburn persists despite maintaining a strict gluten-free diet, other common causes of heartburn should be investigated by a medical professional. These may include dietary factors unrelated to gluten, lifestyle choices, or other medical conditions that can independently cause acid reflux.
When to Consult a Doctor
Seeking medical advice is important if heartburn persists or worsens, even on a gluten-free diet. Consult a doctor if heartburn is accompanied by concerning symptoms like difficulty swallowing, unexplained weight loss, or chronic nausea and vomiting. Any new or unusual digestive symptoms warrant professional evaluation. Self-treatment is not recommended; a healthcare provider can determine the cause and appropriate treatment.
