    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)

    • 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)

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

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

    I have been suffering from severe iron deficient anemia for 2 years. My supplementation keeps being increased every time I meet with the doctor for a progress check. After meeting with 2 doctors who both expressed disbelief about my consistent supplementation, I finally met with a nutrionist who mentioned that gluten intolerance affects nutrient absorption and can cause anemia. I have been following a Gluten Free Diet for 4 weeks and have noticed that my rash has cleared, my acne (I'm 39) has cleared and I have had no problems with bloating or diarrhea. The more I read about Celiac disease, the more it clicks that my mother's side of the family has variations of all the symptoms and medical conditions. I am so thankful to have access to this information thanks to the internet and authors such as you!

    I am 55 years old. I've been diagnosed with everything from IBS, to stress disorders, etc. No doctor ever even suggested I may have Celiac. I have been sick as long as I can remember. I am now gluten free, and very healthy , but have severe osteoporosis. Too bad my sister who is a nutritionist had to be the one to suggest that Celiac may be my problem

    I wonder if my daily reoccurring migraines are celiac disease? A lot of times I will trigger one after eating...I eat pretty carefully and have found that wheat and dairy definitely cause sinus trouble. Bloating and gas are a constant, aches and pains as well--I am 61.

    I have not been diagnosed, nor can I afford to see a doctor for diagnosis (even for, say, a sinus infection), however I suspect I am either gluten intolerant or have Celiac Disease.

     

    I'm 25.

     

    From about the the time I was, oh..13..lactose intolerance started to show up. As every year has passed I've become more and more severely lactose intolerant. More than an ounce of dairy and I am positively ILL. Diarrhea, cramps, bloating, heinous gas. It's terrible. (Even less than an ounce and I become gassy and my stools soften.)

     

    Five years ago I started to develop a migraine aura without headache. The reason I say, 'I started to develop...,' is because within a year and a half it became a constant issue. Today every moment of every single day there are spots are scintillating lights in my left eye. ONLY my left. Photos of my eyes, many visits with retinal specialists and ophthalmologists, an ERG and an MRI later and they still had no idea what was wrong with me. Particularly because it's not bilateral (both eyes). I went a year without any kind of checkups and just a couple of months ago my new Eye Dr. informed me I have macula damage that is not macular degeneration. WELL (here is where it becomes possibly relevant to celiac disease), the mother of a good friend of mine has celiac and nearly went blind from it. As did her mother's brother. A gluten free diet has halted their vision problems.

     

    -For the past three years I suspected I suffer from IBS with constipation, because any time I am feeling stressed, anxious or even just excited (or am going to travel) I get sick for days. Weeks even, sometimes. But over the past six months or so I have been battling a constant cycle of constipation and diarrhea and/or loose stools (not quite diarrhea, but somewhere between normal and diarrhea). Heartburn after I eat almost anything. Constant gas (and I mean constant). I've started retaining fluids way more than seems normal.

     

    I have acute sinusitis, but haven't been able to afford the allergy testing to figure out what the likely culprits are.

     

    Although it was years ago, when I was 19, during a checkup to investigate my thinning hair (more than is normal), constant fatigue and strange heart rhythms it was discovered that I was borderline anemic. Even after taking supplements the problems never went away.

     

    It is a culmination of all of the above that has me convinced to start a gluten free diet. I'm having problems with what to eat for breakfast that is quick, and it's really frustrating, but I'm sure in due time I'll get it all figured out.

     

    I know this is long, but I wanted to bring up the possibility of vision problems in addition to all of the aforementioned symptoms.

    # 18 Please have your husband get tested for gluten intolerance. Celiac disease can be silent with no obvious symptoms. The blood test for Celiac can come back negative even if you have the disease.

    I am 45, and was diagnosed with celiac disease at 8 yrs old, after being in and out of hospital for years. I stayed on the gluten free diet until I was 14 (puberty) when my symptoms began to disappear, and I was able to tolerate gluten. At 40, I began to experience gas, bloating, abdominal discomfort, loose stools, alternated with constipation, and thanks to prei-menopause hot flashes and night sweats. Knowing that I had already been diagnosed with celiac disease, it was a simple matter of going back to the gluten free diet. I now enjoy a healthy body, and even my menopausal symptoms are far less severe than friends who consume gluten experience. I didn't know that celiacs often suffer from lower than usual body temperature. I suspect that all of my children are gluten intolerant as they all have this oddity, as well as complaining of lactose intolerance, my daughter has gone from a size 5 to a OO, but all refuse to accept a gluten free diet. My one son was tested, but because the test came back negative, they all laugh at me, and refuse to even try it. I have tried to tell them that false negatives are common, but what do I know? I'm just their Mom with celiac disease. I appreciate you having put this site out there, so that when they get fed up with the symptoms, they may independently research this. That way they don't have to hear I told you so. Thanks

    My mom was just recently diagnosed with Celiac disease and I know it sounds weird, but it has almost been a godsend to me, because I inherit everything she has. I have Fibromayalgia, arthritis in my hands, terrible vision, diarrhea every single day, my whole body aches, I get severe migraines every other day, I am always bloated, I get heart palpitations, my stools seem oily, etc. And when I did some research, I found that I have pretty much all of the symptoms of Celiac. I'm just starting out on the gluten-free diet, but I am not sure if I should be tested for it, or if I should just try the diet and see if it works. I am under the impression that the only way they can know for sure is to do a biopsy of your bowels...if anyone has any info on that, please let me know! I am only 23 years old and my life is so stressful due to all of these problems. But I feel like I am finally starting to get somewhere. Thanks for all of the information!

    34 - The biopsy is a better test than a blood test, but still not perfect. The usual advise is to get your blood drawn for the test, and THEN start Gluten-Free. Hopefully the blood test will come up correctly and you'll have confirmation of your condition, but if the diet works for you, you know. Give the diet a month to work - some people's systems take a while to heal after years and years of damage, and it sounds like you've got a lot going on there. (celiac often accompanies or is misdiagnosed as FM)

     

    Seems like the list of symptoms given here is pretty incomplete. Constipation, weight gain, migraines, ADD... there are so many other symptoms that are common but don't fit the out-of-date definition of celiac that most doctors go by...

    Very informative. I have all of these symptoms as well and all the doctors thought I was crazy too. They sent me to therapy! I've been gluten free for a month, but still have bad days. I'm being told 3-6 months to feel "normal" again.

    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...
