What is Celiac Disease (aka. gluten intolerance, gluten allergy)?

What is often referred to as a “Gluten Allergy” is actually Celiac Disease. Celiac, which affects 1 in 100 people, is actually not an allergy at all. It is a disorder which causes an autoimmune response with the ingestion of gluten. 

This is often confused with a Wheat Allergy, which causes more traditional symptoms of food allergies such as hives and anaphylaxis.

What are Celiac symptoms in toddlers and how to spot them?

Symptoms of Celiac Disease are diverse, which is why it often goes undiagnosed for a long time. I also see kids with no symptoms at all who were tested because Celiac runs in their family, and in fact are found to have Celiac Disease.

Generally speaking, we have cause for concern when a child has several of these symptoms:

  • Struggling to gain weight
  • Consistent belly aches
  • Rashes
  • poor appetite
  • Headaches
  • Diarrhea
  • Constipation
  • Not showing age appropriate growth

Can Celiac Disease go unnoticed and follow children into their adulthood?

Yes, because symptoms overlap with many other conditions, Celiac often goes unnoticed until adulthood. For example, belly aches, headaches, and even poor appetite may happen for lots of reasons without a true Celiac diagnosis. Though for a wheat allergy, this is usually noticed as the child begins to consume more wheat containing solid foods around 6 months.

How is Celiac Disease diagnosed?

Several blood tests are used to diagnose Celiac Disease, along with endoscopy (looking down the food pipe with a special scope). Some of the blood tests look at levels of inflammation in the body, and others look at an enzyme level that may be affected in those with Celiac Disease.

Wheat allergies are diagnosed like other food allergies. This can be done via blood test or skin patch testing with an allergist.

Non-Celiac gluten intolerance

There is evidence that some people do not tolerate gluten even though they do not have Celiac Disease. There is actually no test for this other than one’s own self-reported symptoms. If a child tested negative for Celiac but is consistently having symptoms you may be advised by your doctor to trial a gluten-free diet in order to identify if gluten is in fact the symptom trigger.
