Managing Celiac Disease: Understanding Food and Dietary Choices

Understanding Celiac Disease

Celiac disease is a serious autoimmune disorder where the ingestion of gluten leads to damage in the small intestine. Gluten is a protein found in wheat, barley, and rye. When people with celiac disease eat gluten, their body mounts an immune response that attacks the small intestine. These attacks lead to damage on the villi, small fingerlike projections that line the small intestine and promote nutrient absorption. When the villi get damaged, nutrients cannot be absorbed properly into the body.

Symptoms of Celiac Disease

Symptoms of celiac disease can vary greatly among individuals and can affect multiple body systems. Common symptoms include:

  • Digestive Issues: Diarrhea, constipation, bloating, gas, and abdominal pain.
  • Weight Loss: Unintended weight loss due to malabsorption of nutrients.
  • Fatigue: Persistent tiredness and weakness.
  • Anemia: Often caused by iron deficiency.
  • Dermatitis Herpetiformis: A skin rash characterized by blisters and itching.
  • Bone or Joint Pain: Due to malabsorption of nutrients like calcium and vitamin D.
  • Neurological Symptoms: Headaches, peripheral neuropathy, and cognitive impairment.
  • Growth Issues in Children: Delayed growth and puberty.
  • Reproductive Issues: Infertility and recurrent miscarriage.

Importance of a Gluten-Free Diet

The only current treatment for celiac disease is a strict, lifelong gluten-free diet. This means avoiding all foods that contain wheat, barley, and rye, as well as their derivatives. A gluten-free diet allows the intestines to heal, alleviates symptoms, and prevents further damage and complications associated with celiac disease.
