Celiac disease is a serious autoimmune disorder affecting the small intestine. It's triggered by eating gluten, a protein found in wheat, rye, and barley. When someone with celiac disease consumes gluten, their immune system reacts abnormally, damaging the lining of their small intestine. This damage prevents the body from properly absorbing nutrients from food, leading to various health problems.
Understanding Celiac Disease
Celiac disease is a chronic condition, meaning it lasts a long time. It's not simply a gluten intolerance or sensitivity; it's an autoimmune response that causes significant damage to the small intestine. This damage interferes with nutrient absorption, potentially leading to malnutrition and other health complications.
Key Characteristics:
- Autoimmune Response: The immune system mistakenly attacks the small intestine in response to gluten.
- Small Intestine Damage: The villi (tiny finger-like projections in the small intestine that absorb nutrients) become damaged and flattened, reducing nutrient absorption.
- Gluten Trigger: Gluten consumption directly triggers the immune response and subsequent damage.
- Genetic Predisposition: Celiac disease is more common in individuals with a genetic predisposition, often linked to family history. It's more prevalent in people of European ancestry.
- Varied Symptoms: Symptoms can range from gastrointestinal issues (diarrhea, bloating, abdominal pain) to anemia, fatigue, and even osteoporosis (bone loss). Some individuals may be asymptomatic (show no symptoms).
Associated Conditions:
Individuals with celiac disease have a higher risk of developing other autoimmune disorders, such as type 1 diabetes. Obesity can also be a contributing factor, as can certain genetic markers.
Diagnosis and Treatment:
Diagnosis typically involves blood tests and an endoscopy with biopsy of the small intestine to confirm the presence of intestinal damage. The primary treatment is a strict lifelong gluten-free diet. Following this diet allows the small intestine to heal and minimizes the risk of long-term complications. Symptoms typically improve within days or weeks of eliminating gluten from the diet. Complete healing of the small intestine can take 3 to 6 months.
