Many people describe a similar situation: Stomach pain, bloating or discomfort after eating – but celiac tests come back normal. That is, they do not have celiac. Could the problem still be related to gluten? The listener asked about his daughter, a soldier, who is not recognized as celiac by the army. And the answer is more complex than it seems.
What Is Celiac?
Celiac is an autoimmune disease, in which exposure to gluten – a protein found in wheat, barley and rye, causes a response from the immune system. The response damages the lining of the small intestine, mainly the absorption bases (the villi), and may lead to malabsorption, nutritional deficiencies, weight loss and sometimes also symptoms outside the digestive system.
The diagnosis of celiac is made using blood tests and sometimes also a biopsy from the intestine. When the diagnosis is positive, the recommendation is clear and unequivocal: Complete avoidance of gluten for life.
And What About Those Who Do Not Have Celiac – But Feel Unwell?
In recent years, there is growing recognition that there is another group: People who do not have celiac, but experience symptoms after consuming wheat products. This condition is sometimes called "Non-Celiac Gluten Sensitivity".
The characteristics may include:
- Stomach pain and bloating
- Gas
- A feeling of heaviness
- And sometimes also fatigue or headaches
But here an important complexity comes in: The cause is not always the gluten itself. Studies show that in many cases the problem is actually related to other components in wheat, mainly a group of carbohydrates called "FODMAPs" – substances that tend to ferment in the intestine and cause bloating and gas, especially in people with a sensitive gut. Studies published in "Gastroenterology" showed that some of the people who thought they were sensitive to gluten actually reacted to these carbohydrates and not to gluten itself. That is, the feeling is real – but the reason is not always what people think.
Where Is Gluten Found?
Gluten is mainly found in wheat, barley, rye, and in practice also in many products that contain them:
- Bread, pitas, pasta
- Cakes and cookies
- Beer
- Sauces and various processed products (sometimes as a stabilizer or thickener)
In contrast, foods such as rice, potatoes, legumes, corn, quinoa and more – do not naturally contain gluten.
<br>Is There a Test for Non-Celiac Sensitivity?
And here comes a critical point: As of today, there is no definitive medical test that diagnoses "Non-Celiac Gluten Sensitivity". The diagnosis is usually made by ruling out celiac, ruling out other conditions, and then trying a dietary elimination of gluten and examining improvement in symptoms. That is, it is more of a process of trial and response, and not a clear laboratory diagnosis.
Is a Wheat-Free Diet Healthy?
Another point the listener asked about, and the answer is that here too it is important to be precise. There is no nutritional requirement to consume wheat, and it is possible to build a completely balanced, varied and high-quality diet without it.
In fact, for many people, reducing processed wheat products, such as white breads, pastries and snacks – can actually improve the quality of the diet. When replacing them with more natural foods such as vegetables, legumes, other whole grains and high-quality proteins, the result is a richer and more balanced diet. However, it is important to avoid automatically replacing wheat products with processed "gluten-free" products, which sometimes contain more sugar, fat or additives.
Bottom Line
Stomach pain after eating wheat is not necessarily celiac, but it is also not always "imagination". There are intermediate conditions, and sometimes the cause is actually other components in the food. The right approach is not to rush to label, but to check, listen to the body, and build a diet that is personally suitable – even if it includes less wheat, or none at all.
