**What is Celiac Disease?**
**Question: What is celiac disease?**
**Answer:** Celiac disease is an autoimmune disorder that occurs when consuming gluten, a protein found in wheat, barley, rye, and sometimes oats. The immune system mistakes gluten for an invader and attacks the small intestine, causing damage and interfering with nutrient absorption.
**Question: What causes celiac disease?**
**Answer:** The exact cause is unknown, but genetics and environmental factors are believed to play a role. Individuals with certain genetic markers are more likely to develop celiac disease, but it often becomes apparent only after an environmental trigger, such as a viral infection or stress.
**Question: What are the symptoms of celiac disease?**
**Answer:** Symptoms can vary depending on the severity of the condition. Common symptoms include:
* Gastrointestinal: Abdominal pain, diarrhea, constipation, bloating, gas
* Weight loss
* Anemia
* Fatigue
* Nutrient deficiencies (e.g., iron, vitamin B12)
* Mood disorders (e.g., anxiety, depression)
**Question: How is celiac disease diagnosed?**
**Answer:** Celiac disease is diagnosed through a combination of blood tests to check for antibodies against gluten and genetic testing to identify the presence of celiac-associated genes. A small intestine biopsy may also be performed to examine the intestinal tissue for damage.
**Question: How is celiac disease treated?**
**Answer:** The only effective treatment for celiac disease is a strict gluten-free diet. This involves eliminating all sources of gluten from the diet, including foods, beverages, and medications. Adhering to a gluten-free diet allows the small intestine to heal and symptoms to subside.
**Question: What are the long-term effects of untreated celiac disease?**
**Answer:** Untreated celiac disease can lead to severe health complications, including:
* Malnutrition
* Chronic inflammation
* Autoimmune disorders
* Increased risk of intestinal cancer
