    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
    • Ataxia, neuropathy, brain disorders

    I have suffered with heartburn since I was a little kid. Two years ago I sought a doctor's help for an annoying chest pain. All the tests proved nothing wrong with my heart but indicated that my blood sugar was little high. I also complained about my heartburn and a bloating sensation. He sent to a specialist meanwhile the blood test result came back which he told me to show to the specialist. I did some search and found your site....I'm gluten free and heartburn free!

    I did not go to the specialist yet but one thing is bothering me today--that bloating sensation came back with a severe diarrhea....I'm worried that this can be something more serious. Why didn't my doctor find out earlier?

    I've been diagnosed with everything listed here, just about. It's been suggested that I need to see a nice therapist.

     

    I finally figured out myself (at age 48) that if I don't eat wheat, my excema and heartburn clear up, and many other symptoms die down. (I was still eating other gluten-containing products, just no wheat bread or pasta.)

     

    With that added info, my doctor of 15 years told me that I'm celiac.

     

    She said: we can do the blood test; but, you have to eat enough gluten to become really sick before we can do it, and even if it comes back negative, it doesn't mean you're not.

     

    Then, the gold standard test is to do the biopsy.

     

    And then - if that comes back positive - then we know for sure. And then we'll tell you, don't eat gluten.

     

    But, she said, we can already tell you that now. So, you can do the tests if you really want to be sure ...

     

    I said no thanks, my symptoms are being clear and specific already. And the longer I'm off gluten - the more clear and specific they are when I eat some. (Like, WHACK!! DON'T DO THAT AGAIN!!)

     

    So, #34, try the diet. Be strict with it. If it works ... there turn out to be some people (who are not celiac, but have other tolerance issues) who cannot eat wheat, but can eat other related products such as spelt or farro. On the other hand, if the strict diet doesn't do anything to improve your issues - you have something else going on, but you've eliminated a hard-to-test for set from consideration.

    I suffered with many of these symptoms for about 10 years before finally talking to my doctor. He sent me for a gastroscopy and colonoscopy, which turned out positive for Celiac Disease. The gluten-free diet certainly helps with the intestinal problems although I still have some really bad days with diarrhea. I am still fatigued all the time and I have continuously gained weight over the years. I wonder why all the articles indicate weight loss, and everyone I meet with celiac disease including gluten-free cooking classes are 'skinny' while I am so overweight. Diet and exercise have done nothing to reduce my weight. It is very depressing.

    My diagnosis came after years of being anemic even after taking 6 iron tabs daily. Other symptoms included loose stools, bloating, small blisters on my arms, occasional swelling of my hands, gums bleeding/inflammation but no stomach aches. I was diagnosed after a small bowel biopsy. Celiac disease, I learned, is an autoimmune disorder and often accompanies type 1 diabetes which I have had for years. If you do not follow the diet, malabsorption of nutrients will continue along with the potential for cancer to develop, so says my doctor. I have been eating gluten free for almost 2 years. It is an adjustment but you get use to the diet. My last biopsy this summer showed 100% recovery of my small intestine and past problems listed above completely gone. Worth the conscious effort!

    Thank you so much for posting this information and hopefully helping many other people decide to get tested. My 6 year old daughter was on Mirilax prescribed by her doctor for 2 years because they thought she had Chron's disease after sending her for an x-ray. After visiting the doctors tons of times for her severe stomach aches after that, I finally said enough is enough. I insisted on getting her further testing. They finally sent her for blood work and found her celiac panel came back positive. She is still waiting to get a biopsy of her intestines to confirm, but I have given her gluten free foods for 4 days now and she is a totally different kid!!!!!! It's been expensive but good things are never cheap! She's worth every penny and more.

    Alopecia Areata, esp. the most severe forms--totalis and univeralis, have all been attributed in some cases to celiac disease, in fact, being the ONLY symptom. Alopecians have a higher rate of celiac disease than the general population. Weight loss is not nec. an indicator. Also, people with fair skin and red or strawberry hair are likely candidates, as well. I have alopecia, and I have a cousin who died of lymphoma before age 30. She and I are both fair-skinned redheads. I now believe she had undiagnosed celiac disease. Thanks, I just wanted to add my two cents...

    I have been having problems for mostly all of my life. Stomach cramps, bloating, diarrhea, etc. I have been tested for Celiac Disease and am waiting for my results to come back. I have lost a fair amount of weight, and always feel like I want to vomit. I am hoping that I get to the bottom of this...as I can not take much more of this. Reading some of the other posts have opened my eyes as to see that I am not alone .

    Thank you

    Can someone please explain to me why a simple blood test was not done by my doctor? I explained all the symptoms that I had, but at the time I was unaware of celiac disease. You would think the doctor should be aware of the disease. I went through an upper and lower GI, to find out I'm fine. NOT...I was not imagining these symptoms. I figured it out on my own, thanks to articles and great people sharing their stories. Thank you to all of you! We need to get the doctors to test for this, it is a simple blood test. It will prevent unnecessary surgery that is happening.

    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
    Celiac.com 04/16/2019 (originally published 04/24/2008) - Genetic tests for celiac disease and gluten sensitivity are readily available. Testing can be performed on either blood and mouth swab samples. Tests can be done at home and mailed to the lab for analysis.
    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...
