Celiac Disease

Celiac disease is a chronic autoimmune disorder that primarily affects the small intestine and is caused by a reaction to gluten, a protein found in wheat, barley, and rye.

Causes and Risk Factors

  • The exact cause of celiac disease is unknown, but it is believed to be a combination of genetic and environmental factors.
  • Gluten triggers an immune response that damages the lining of the small intestine, leading to malabsorption of nutrients.
  • Individuals with a family history of celiac disease are at higher risk of developing the condition.
  • Certain genetic markers, such as HLA-DQ2 and HLA-DQ8, are associated with an increased risk of developing celiac disease.

Symptoms

Diagnosis

  • Physical examination and medical history
  • Blood tests to detect the presence of certain antibodies, such as tissue transglutaminase antibody (tTGA) or endomysial antibody (EMA)
  • Intestinal biopsy to examine the lining of the small intestine for damage
  • Genetic testing to identify genetic markers associated with celiac disease

Treatment and Management

  • A strict gluten-free diet is the primary treatment for celiac disease.
  • Avoiding foods that contain wheat, barley, and rye, such as bread, pasta, cereals, and baked goods.
  • Reading food labels carefully to identify hidden sources of gluten.
  • Working with a registered dietitian or healthcare provider to develop a personalized meal plan.

Complications

Prevalence and Demographics

  • Celiac disease affects approximately 1 in 100 people worldwide.
  • The condition is more common in females than males.
  • Celiac disease can occur at any age, but symptoms often appear during childhood or early adulthood.
