    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
    • Chronic fatigue syndrome, fibromyalgia
    • Crohn’s disease, irritable bowel syndrome
    • Dermatitis herpetiformis, eczema, psoriasis
    • Diabetes (type 1)
    • Down syndrome
    • Epilepsy, seizures
    • Hashimoto’s thyroiditis, thyroid disorders
    • Liver and biliary disorders (fatty liver, PSC)
    • Lupus, multiple sclerosis, scleroderma
    • Refractory celiac disease, collagenous sprue

    Oh boy. I have just finished reading all of these comments. I just got out of the hospital after a 4 day stay. Blood-work and colonoscopy(4th). Pending Crohn's and celiac. I have had all the symptoms since I was around age 40. Now I'm 55. The doctors usually diagnose me as being depressed. Yikes!!!! Yeah sure, it's just my imagination! I have had so many tests. Even went to UCLA where they performed invasive tests and found nothing. Don't think they ever mentioned Celiac Disease. I'm so tired of the diarrhea and stomach cramps, migraines, fatigue, no desire to thrive, moody, irritable, nausea, hypothyroidism, itchy scalp, hair thinning, weight loss/gain, clearing my throat all the time, etc. etc. I feel so helpless.

    I think it's a great website to go to. I'im just learning about celiac although I have not been diagnosed.But a lot of the symptoms I have are symptoms of the disease and I'm really glad there is a site that can give great information on something I had never heard if thank you.

    This site has been very informative. I have struggled with several symptoms over the years including severe fatigue, OCD, anxiety, depression, TICS, sleep apnea, IBS, polyps, immune system changes and weight fluctuation. Now my 10 month old son has had terrible oozing rashes since he was 2 months old and no doctors have been able to explain it. He was tested for celiac disease and rated as a very high risk for celiac. I was recently tested myself and one antibody tested high as the others were low. Still hoping this could be the answer to our problems and will be starting a gluten-free diet for 3 months as a diagnostic tool.

    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.

    There is no need for this diet to be expensive. Just cut out most of the grain products and go for gluten free old fashioned oats, buckwheat & brown rice with a little gluten free bread now and then. You'll figure out ways to eat inexpensively. The gluten free grain products are mostly junk food anyway. My suggestion is not to have ANY products in the house that contain gluten. ALL will be healthier.

    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.

    Stephanie;

     

    Thank you for your post, and as I have been researching celiac disease this is the first mention of vision issues I have come across. I too have many of the posted symptoms, most noticeable during my work in Thailand during the Tsunami. Given the conditions at the time we drank a lot of the local bottled beer instead of water and for the stress release. It was then that I noticed that I was swelling immediately upon consumption. My ankles were huge along with all over body swelling. When I spoke with my doctor back in the states he just suggested it was an allergy to beer and to take water pills. Ever since then I have had lots of swelling and water retention after drinking beer. Also I have noticeable vision issues, where I have deemed myself night blind. Also without health insurance and unable to afford a doctors visit or testing I have been on a gluten-free diet for a week now. I have not had any water retention or swelling in legs since!

     

    Breakfast, I have a whey protein shake or egg white omelet.

    Feed them vegetables, beans, meat, rice, and fruit. That is what everyone should be eating anyway. I have two fruit bowls on the counter at all times for my four kids.. whatever fruit is on sale. Eggs for breakfast. Do not buy processed foods. You entire family will live longer and healthier without them.

    For many years my Mum was labeled as having Muscular Dystrophy, she lost weight, developed muscle weakness, ended up in a wheelchair. She also had severe constipation, bloating and indigestion. Now aged 87, it's only been in the past few years we've discovered that gluten brings all these symptoms and by avoiding it her bowels are working fine. Too late for her to walk again though, so I implore everyone who even suspects they are gluten intolerant to avoid it like the plague! Incidentally, no doctor diagnosed it or even considered it, only through extensive reading did we decide to try it.

    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.

    You need to have daughter drug tested. It's likely she is going through withdrawals and her eating gluten may only be a coincidence. Gluten consumption should not have anything to do with her anger. Drug withdrawals, even nicotine, can cause a very moody or angry person.

    It is not easy living with celiac, especially when you have to eat outside most of the time.

    I have similar symptoms. Has your hair grown back since going gluten-free? Thanks!

    After surviving rectal cancer, chemotherapy, radiation, an ileostomy, an ileostomy take down; food allergies - particularly to Gluten it seems - have worn me down to a frazzle and made me incredibly sick. Am undergoing testing for celiac disease and hope for the best. Thanks for the information.

    I'm happy you found a possible answer I hope you thrive.

    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.

    In the United States and Canada, the designation of Naturopathic Doctor (ND) or naturopathic medical doctor (NMD) may be awarded after completion of a four year program of study at an accredited Naturopathic medical school that includes the study of basic medical sciences as well as natural remedies and medical care.

     

    Maybe you should take your husband to get some blood work done...I wouldn't just leave it to one person's opinion. You could be handing him a death sentence by continuing to eat the way you 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 ...

    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...
