Coeliac disease (also spelled celiac) is a chronic autoimmune disorder where the body reacts abnormally to gluten, a protein found in wheat, barley, and rye. When someone with coeliac disease consumes gluten, their immune system attacks the small intestine, damaging its lining and preventing proper nutrient absorption.
This condition affects people of all ages, from children to adults, and requires lifelong management through a strict gluten-free diet. If left untreated, it can lead to serious health complications like malnutrition, osteoporosis, and even certain cancers.
Symptoms of Coeliac Disease
Symptoms vary widely, making diagnosis tricky. Some people experience severe digestive issues, while others have mild or no obvious symptoms. Common signs include:
Digestive Symptoms:
• Diarrhea or constipation
• Bloating and gas
• Stomach pain
• Nausea and vomiting
Non-Digestive Symptoms:
• Unexplained weight loss
• Fatigue and weakness
• Anemia (low iron levels)
• Bone or joint pain
• Skin rash (dermatitis herpetiformis)
• Headaches or migraines
• Mood changes (anxiety, depression)
Children with coeliac disease may also experience delayed growth, short stature, or behavioral issues.

Causes and Risk Factors
The exact cause of coeliac disease is unknown, but it involves a combination of:
• Genetics – People with certain genes (HLA-DQ2 or HLA-DQ8) are more likely to develop it.
• Environmental triggers – Infections, gut bacteria changes, or high gluten consumption early in life may contribute.
• Autoimmune response – The immune system mistakenly attacks the intestine when gluten is present.
Risk factors include:
• Family history of coeliac disease
• Type 1 diabetes or thyroid disorders
• Down syndrome or Turner syndrome
Diagnosis and Testing
If you suspect coeliac disease, consult a doctor. Diagnosis involves:
1. Blood Tests – Checks for antibodies (tTG-IgA) that indicate an immune reaction to gluten.
2. Endoscopy & Biopsy – A small intestine sample is taken to confirm damage.
Important: Do not start a gluten-free diet before testing, as it can lead to false-negative results.
Management and Treatment
The only effective treatment for coeliac disease is a strict gluten-free diet. This means avoiding:
• Wheat (bread, pasta, cereals)
• Barley (beer, malt)
• Rye (rye bread, some cereals)
Safe Foods:
• Rice, quinoa, corn
• Fruits, vegetables, nuts
• Meat, fish, eggs
• Dairy (unless lactose intolerant)
Tips for a Gluten-Free Lifestyle:
• Read labels carefully – Gluten can hide in sauces, soups, and processed foods.
• Use separate kitchen tools – Avoid cross-contamination.
• Dine out cautiously – Inform restaurants about your dietary needs.
• Consider supplements – Some patients need vitamins (iron, calcium, vitamin D).
Potential Complications if Untreated
Ignoring coeliac disease can lead to:
• Malnutrition – Due to poor nutrient absorption.
• Osteoporosis – Weak bones from calcium deficiency.
• Infertility or miscarriages – Linked to untreated coeliac disease.
• Neurological issues – Nerve damage or seizures in rare cases.
• Increased cancer risk – Intestinal lymphoma in severe cases.
When to See a Doctor
If you experience persistent digestive issues, unexplained weight loss, or fatigue, consult a doctor. Early diagnosis helps prevent complications.
