Celiac Disease: Symptoms and Causes

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article.  Celiac disease is a multifaceted condition with a wide range of symptoms and causes. While a gluten-free diet remains the cornerstone of treatment, many patients continue to experience persistent symptoms. Ongoing research into novel therapeutic agents and the role of environmental factors is crucial for improving the management and quality of life for individuals with celiac disease.

Celiac disease (CeD) is a chronic autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. This condition affects genetically predisposed individuals, leading to a range of gastrointestinal and extra-intestinal symptoms. Despite adherence to a gluten-free diet (GFD), which is the primary treatment, many patients continue to experience persistent symptoms. This article explores the symptoms and causes of celiac disease, drawing on recent research findings.

Symptoms of Celiac Disease

Gastrointestinal Symptoms

The most common symptoms of celiac disease are gastrointestinal in nature. These include chronic diarrhea, abdominal pain, bloating, and malabsorption of nutrients. Studies have shown that even with strict adherence to a GFD, some patients continue to experience these symptoms. For instance, a study on larazotide acetate, a novel therapeutic agent, demonstrated a reduction in gastrointestinal symptoms in CeD patients who were symptomatic despite following a GFD1.

Extra-intestinal Symptoms

Celiac disease can also manifest through extra-intestinal symptoms such as fatigue, headache, and joint pain. Research indicates that these symptoms can persist even in patients on a GFD. The same study on larazotide acetate found a significant decrease in non-gastrointestinal symptoms like headache and tiredness, highlighting the complexity of managing CeD1.

Psychological and Neurological Symptoms

Patients with celiac disease often report psychological and neurological symptoms, including depression, anxiety, and cognitive impairment. A study focusing on the effects of a personalized nutritional plan and resistance exercise program found that women with CeD experienced improvements in mood and menopause-associated symptoms when adhering to a GFD combined with exercise6.

Causes of Celiac Disease

Genetic Predisposition

Celiac disease is strongly associated with specific genetic markers, particularly the HLA-DQ2 and HLA-DQ8 genes. These genetic factors predispose individuals to an abnormal immune response to gluten, leading to the characteristic intestinal damage seen in CeD patients4.

Immune Response to Gluten

The ingestion of gluten triggers an immune response in individuals with celiac disease, leading to inflammation and damage to the small intestine’s mucosal lining. This immune response is characterized by the production of specific antibodies, such as endomysial antibodies, which are highly predictive of villous atrophy, a hallmark of CeD4.

Environmental Factors

While genetic predisposition is necessary for the development of celiac disease, environmental factors also play a crucial role. The timing and amount of gluten introduction in the diet, as well as infections and other environmental triggers, can influence the onset and severity of the disease4.

Persistent Symptoms Despite a Gluten-Free Diet

Incomplete Mucosal Healing

One of the challenges in managing celiac disease is the persistence of symptoms despite a strict GFD. Research has shown that some patients do not achieve complete mucosal healing, which can contribute to ongoing symptoms. A study on latiglutenase, an enzyme designed to break down gluten, found that it could protect the mucosa and reduce symptom severity in CeD patients exposed to gluten2.

Non-Celiac Gluten Sensitivity

Some individuals experience symptoms similar to celiac disease but do not have the characteristic intestinal damage or antibodies. This condition, known as non-celiac gluten sensitivity (NCGS), can complicate the diagnosis and management of gluten-related disorders. A study investigating the effects of gluten in patients with self-reported NCGS found no specific or dose-dependent effects of gluten after reducing fermentable, poorly absorbed carbohydrates (FODMAPs) in their diet3.
