    Celiac.com 09/19/2025 – Celiac disease is a chronic autoimmune condition triggered by eating gluten. It can cause a wide range of symptoms, from digestive problems to skin, bone, and neurological issues. Some people experience many symptoms on a daily basis, while others may have only a few or none at all. Because symptoms vary so widely, celiac disease can be difficult to recognize and diagnose.

    7 Major Categories of Celiac Symptoms

    1. Digestive symptoms: abdominal pain, bloating, gas, diarrhea, constipation, nausea, vomiting, steatorrhea (fatty stools).
    2. Non-digestive symptoms: fatigue, weakness, anemia, weight loss, malnutrition, delayed growth, irritability, depression, anxiety, brain fog.
    3. Skin symptoms: itchy rash, blistering, dermatitis herpetiformis, eczema.
    4. Bone and muscle symptoms: joint pain, muscle pain or cramps, osteoporosis.
    5. Neurological symptoms: headache, migraine, ataxia, neuropathy, seizures, cognitive problems.
    6. Reproductive symptoms: infertility, irregular periods, recurrent miscarriage.
    7. Silent celiac: no obvious symptoms despite intestinal damage.

    Symptoms in Adults vs. Children

    Adults most often experience diarrhea, fatigue, and weight loss. Other common adult symptoms include bloating, gas, abdominal pain, nausea, and constipation. Many of these problems are linked to nutritional deficiencies caused by intestinal damage and poor nutrient absorption.

    Symptoms in Children

    Celiac.com Sponsor (A12):
    In children under 2, symptoms may include vomiting, chronic diarrhea, failure to thrive, muscle wasting, poor appetite, and a swollen belly. Older children may show diarrhea or constipation, weight loss, irritability, short stature, delayed puberty, and neurological problems such as ADHD, learning difficulties, headaches, poor coordination, and seizures.

    Why Symptoms Can Be Confusing

    Many celiac symptoms are vague and can be mistaken for other conditions. These include dental enamel defects, osteoporosis, depression, joint pain, mouth sores, skin rashes, and tingling or numbness in the feet and legs. Because celiac can mimic anemia, Crohn’s disease, irritable bowel syndrome, ulcers, or even skin and nerve disorders, diagnosis is often delayed.

    Common Signs and Symptoms

    • Abdominal pain, gas, bloating, cramps
    • Acne, eczema, dry skin, rashes
    • Anemia (iron or folate deficiency)
    • Ataxia (gluten ataxia)
    • Diarrhea or constipation
    • Dental enamel defects
    • Delayed puberty, short stature, failure to thrive
    • Fatigue, weakness, malaise
    • Frequent headaches or migraines
    • Joint or muscle pain, cramps, weakness
    • Infertility, recurrent miscarriage
    • Neuropathy (tingling or numbness in hands/feet)
    • Malnutrition and weight loss/gain
    • Osteoporosis, low bone density
    • Panic attacks, anxiety, depression
    • Stomach rumbling, nausea, vomiting
    • Vitamin and mineral deficiencies (A, B, D, E, K, zinc)

    Conditions Associated with Celiac Disease

    People with the following conditions are at higher risk for celiac disease:

    • Addison’s Disease
    • Anemia
    • Anorexia nervosa, bulimia
    • Arthritis, asthma
    • Autism, ADHD

    Thank You for the informative information. I am now raising 4 grandchildren on my own (son deceased) and have found out that 2 of the children need to be on this diet. I hear how expensive it is and don't know how I am going to be able to accomplish all I need to for their benefit, but having this site for information and resources is a God send. Looking forward to trying some of the recipes.

    THANKS FOR THE GOOD, CLEAR EXPLANATION. It is important to also mention non = celiac gluten sensitivity, as there are many more conditions that are caused by gluten consumption, including the many auto-immune diseases. New ones are being added to the list, such as Narcolepsy and even Parkinson's. Cutting out the consumption of gluten (wheat, barley and rye) can lead to healing and resumption of a normal life. Spread the word, support the research!

    Another symptom no-one has mentioned is how it can affect the brain and make it impossible for the person to control anything they say and do after eating gluten. I know as this is how it affects my daughter. ADD no, OCD no, but she got very angry three hours after eating gluten. She also has the stunted growth.

    Thanks for all this information. My husband has been to see a person calling himself a Naturopath, who looked into his eyes, and then declared him to be gluten-intolerant. My husband has none of the above symptoms, so I'm feeling reassured that I needn't go through the hassle of buying gluten-free products, when I'm trying to raise 4 kids on a restricted budget! We tried it for a week, but it's really very hard to keep up with if it's not really necessary.

    After reading your article, I intend to see my gastroenterologist for testing. I seem to have some of the symptoms of glucose intolerance. He recently tested me for lactose intolerance and found me to be highly lactose intolerant.

    I have been working with my gastroenterologist for several years trying to diagnose my condition. She finally determined that my gallbladder needed to be removed, however my celiac symptoms got worse after that. My whole family has converted to a gluten free diet. For the most part things are working out for the better, but I still have the intestinal problems and overall fatigue even after 8 hours or more of sleep.

    After suffering with different things over the years I was recently tested for Celiac, which I will not received the results until next week, in order for the test to be accurate I had to eat a wheat and Gluten diet for at least 10 days before the test. I have not had wheat in my diet for the last 3 years. I started off with a few symptoms, headaches, gas, bloating, rash, needing to clear throat a lot, heart palpitations etc; What concerned me the most was as the days went on I was so fatigued could hardly get out of bed, my mind and motor skills slowed way down and got very fuzzy, was not able to make important decisions and certainly unable to drive. After eating pancakes with my daughter one morning we were talking and all of a sudden I wasn't able to form certain words. That was so very scary. I don't really need the results to tell me I have a problem with wheat and gluten, other than it being hereditary, and needing to know for sure. It frightens me to think so many people have this and will never know. They , meaning people and their doctors treat the symptoms and not the culprit. Thank you for all the information, I'm sure I will need it. Take Care and God Bless!

    I have had trouble with being overweight since I was a child. I am 20 yrs old now and weight 300. I get sick after I eat almost always. I get pains in my stomach , gas , or diarrhea. I also have dermatitis on my scalp. Been told several times its the way I eat, but after reading I think I could possibly have this. On another site someone mentioned boils. Have any of you experienced this? I have had issues with this myself. All in all this is a very informative site . Thank you

    I've had diarrhea for about 10 years. My temperature is always 97. Something instead of 98.6. I was sick at home one day and googled about low body temperatures and it said many times people with a gluten allergy run low temperatures..I immediately got off gluten and I have felt much better and my intake of Immodium is seldom instead of every day. Thanks for the website. I refer to it almost everyday for information.

    I have suffered for years with what was diagnosed as IBS. I have almost all the symptoms in your article & more & after many many visits to the doctors over the years I have at last got a doctor who has had the decency to get me checked out properly. I am awaiting the results & hoping that the ignorance of my prior doctor hasn't caused it to have gone too far. I suggest that anyone suffering these conditions don't let their doctor fob them off as I have been for at least 15 years. The only difference I have to the symptoms in this article is that I gained weight and cannot get it off no matter what diet or exercise I do.

    Celiac Disease Screening
    Celiac.com 03/05/2019 - Doctors commonly suggest celiac screening for anyone with a family history of celiac disease, or of disorders such as thyroid disease, anemia of unknown cause, type I diabetes or other immune disorders or Downs syndrome. Otherwise, patients are generally screened on a case by case basis according to individual symptoms.
    Blood Testing - Antibodies Point to Celiac Disease
    Screening for celiac disease usually begins with a blood test.
    People with celiac disease have abnormally high levels of associated antibodies, including one or more of the following: anti-gliadin, anti-endomysium and anti-tissue transglutaminase, and damage to the villi (shortening and villous flattening) in the lamina propria and crypt regions of their intestines when they ...

    Ten Facts About Celiac Disease Genetic Testing

    A good testing laboratory will provide an accurate prediction of celiac disease risk, and will also provide information about the statistical risk to your children, your likelihood of developing more severe celiac disease, whether one or both of your parents had the risk gene, and for some laboratories, you may determine your risk of gluten sensitivity without celiac disease.

    Nutrient Deficiencies and Celiac Disease: Understanding the Connection
    Celiac.com 04/15/2023 - Celiac disease is a chronic autoimmune disorder that affects the small intestine, triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. One often overlooked consequence of untreated and undiagnosed celiac disease is the potential for nutrient deficiencies. Due to the damage caused to the lining of the small intestine, absorption of various essential nutrients may be impaired, leading to deficiencies that can have wide-ranging health effects. In this article, we will explore the connection between celiac disease and nutrient deficiencies, focusing on several key vitamins, minerals, and other essential nutrients.
    The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron...
