This site is intended to share the answers I found in my quest to understand celiac disease with family,  friends, and others who may be trying to find the answers I too have been seeking. This is a compilation of answers from various sources (clearly listed and linked prior to the quotes).

What are the symptoms of celiac disease?

(Source: Celiac Disease Symptoms)

“Digestive symptoms are more common in infants and children…  Adults are less likely to have digestive symptoms, with only one-third experiencing diarrhea.”

• abdominal bloating and pain
• chronic diarrhea
• vomiting
• constipation
• pale, foul-smelling, or fatty stool
• weight loss
• fatigue
• irritability and behavioral issues
• dental enamel defects of the permanent teeth
• delayed growth and puberty
• short stature
• failure to thrive
• Attention Deficit Hyperactivity Disorder (ADHD)
• unexplained iron-deficiency anemia
• fatigue
• bone or joint pain
• arthritis
• osteoporosis or osteopenia (bone loss)
• liver and biliary tract disorders (transaminitis, fatty liver, primary sclerosing cholangitis, etc.)
• depression or anxiety
• peripheral neuropathy ( tingling, numbness or pain in the hands and feet)
• seizures or migraines
• missed menstrual periods
• infertility or recurrent miscarriage
• canker sores inside the mouth

What are the long term health effects of celiac disease (if a gluten-free diet is not followed)?

(Source: What is Celiac Disease?)

“Celiac disease can develop at any age after people start eating foods or medicines that contain gluten. Left untreated, celiac disease can lead to additional serious health problems. … Celiac disease is [also] associated with a number of autoimmune disorders, with the most common being thyroid disease and Type 1 Diabetes.”

• Iron deficiency anemia
• Early onset osteoporosis or osteopenia
• Infertility and miscarriage
• Lactose intolerance
• Vitamin and mineral deficiencies
• Central and peripheral nervous system disorders, including ataxia, epileptic seizures, dementia, migraine, neuropathy, myopathy and multifocal leucoencephalopathy
• Pancreatic insufficiency
• Gall bladder malfunction
• Non-Hodgkin lymphoma (intestinal and extra-intestinal, T- and B-cell types)
• Small intestinal adenocarcinoma
• Esophageal carcinoma
• Papillary thyroid cancer
• Melanoma
• Arthritis/Juvenile Idiopathic Arthritis
• Addison’s Disease
• Autoimmune Hepatitis
• Hashimoto’s Thyroiditis (Autoimmune Thyroid Disease)
• Crohn’s Disease; Inflammatory Bowel Disease
• Chronic Pancreatitis
• Down Syndrome
• Idiopathic Dilated Cardiomyopathy
• IgA Nephropathy (Berger’s Disease)
• Irritable Bowel Syndrome (IBS)
• Lupus
• Multiple Sclerosis
• Primary Biliary Cirrhosis
• Primary Sclerosing Cholangitis
• Psoriasis
• Rheumatoid Arthritis
• Scleroderma
• Sjogren’s Syndrome
• Turner Syndrome
• Type I Diabetes
• Ulcerative Colitis; Inflammatory Bowel Disease
• Williams Syndrome


What are the dangers of undiagnosed celiac disease?

(Source: Celiac Disease: Should There Be Screening for All – Consequences of undiagnosed celiac disease (AGA Perspectives, Vol. 8 No. 2 | April/May 2012 (linked from

“Undiagnosed celiac disease may increase morbidity, economic burden and mortality. Many people with undiagnosed celiac disease may seek substantial health care before being correctly diagnosed. Increased mortality risk is a concern and may require further comment. All-cause mortality was increased four-fold among young men with undiagnosed celiac disease than among seronegative referent subjects during 45 years of follow-up. This finding was supported by a European study that demonstrated a twofold increased mortality risk among middleaged men and women with positive tissue transglutaminase antibody. However, other studies that either included older individuals and/or had a shorter follow-up failed to confirm these observations. The mortality risk might be influenced by the amount and duration of gluten consumed before and after celiac disease onset. Thus, detection of celiac disease — to be effective — should be started early in life if it will impact survival.”

Comprehensive “symptom” list

[conditions that may have been caused by celiac disease (and hence a clue to the possibility of celiac); It makes sense that people could have such a wide variety of symptoms (or even a lack of symptoms), if you consider that celiac causes the intestine not to send nutrients to some body systems that need them to perform correctly.  Which body systems are effected varies from person to person depending on which nutrients are not being sent.]
