Celiac disease is an autoimmune disease triggered by the consumption of gluten. When someone with the disease eats gluten, their immune system responds to it like it would a foreign invader and, in the process of destroying the gluten, it accidentally destroys healthy gut tissue.
Because celiac disease causes progressive damage to the small intestine, many people who go undiagnosed for any length of time develop malnutrition and/or nutritional deficiencies. As you can imagine, the consequences of such can be extremely dangerous for children. But what does celiac disease look like in children compared to adults?
Celiac disease symptoms look different in children depending on their age. If a child has developed celiac disease at birth, symptoms will usually be present after gluten-containing foods are regularly introduced into the child’s diet.
Here are some of the most common symptoms of celiac disease in infants and toddlers:
- Vomiting
- Irritability
- Bloating
- Poor growth
- Distended abdomen
- Diarrhea
- Very foul-smelling stools
- Malnutrition
When a school-age child develops celiac disease, the symptoms are less likely to include vomiting but may still include other types of digestive distress. Here are some common symptoms of celiac disease in school-age children:
- Distended abdomen
- Diarrhea
- Constipation
- Stomach aches
- Abdominal pain
- Difficulty gaining or losing weight
As school-age children become teenagers and young adults, they will develop symptoms that are not closely related to the gastrointestinal tract – these are called “atypical” or “extra-intestinal” symptoms. Here are a few examples:
- Unexplained weight loss
- Stunted growth
- Delayed onset of puberty
- Painful bones or joints
- Chronic fatigue
- Recurrent headaches and migraines
- Dermatitis herpetiformis (itchy skin rash)
- Recurring mouth sores (aphthous ulcers)
There are some cases in which children have only mild symptoms or no symptoms at all. These cases can be particularly difficult to diagnose.
Remember, celiac disease looks different in every patient and symptoms can develop at any age. For adults, chronic fatigue is one of the most common symptoms, but many children exhibit irritability. Only about 20% to 30% of children with celiac disease have stomach-related symptoms.
If you suspect that your child may have celiac disease, don’t delay in talking to your pediatrician to get a blood test. Keep in mind that you’ll have to keep your child on a gluten-containing diet in order for the results to be accurate – your child may also require additional testing if the results are positive.
