Understanding Gluten and Its Effects on the Body
This section delves into the specifics of what gluten is and how it affects individuals with celiac disease and non-celiac gluten sensitivity, providing insights into the symptoms that accompany gluten intolerance.
What is Gluten?
Gluten is a composite protein found in grains such as wheat, barley, and rye. It gives elasticity to dough, helping it to rise and maintain its shape, and often gives the final product a chewy texture. Gluten is not just a single protein but a family of proteins, with gliadin and glutenin being the most prevalent in wheat.
Celiac Disease vs. Non-Celiac Gluten Sensitivity
Celiac disease is a serious autoimmune condition triggered by consuming gluten, leading to damage in the small intestine. This reaction can cause a myriad of issues ranging from nutrient deficiencies to increased risks for other autoimmune disorders. Non-celiac gluten sensitivity (also referred to as gluten intolerance), while not an autoimmune response, can lead to symptoms similar to those of celiac disease, without causing intestinal damage.
| Celiac Disease | Non-Celiac Gluten Sensitivity |
|---|---|
| Autoimmune disorder | Not an autoimmune response |
| Damage to small intestine | No intestinal damage |
| Requires lifelong avoidance of gluten | May tolerate small amounts of gluten |
Signs and Symptoms of Gluten Intolerance
Symptoms of gluten intolerance can include bloating, diarrhea, gas, fatigue, nausea, abdominal pain, skin rash, and brain fog. These symptoms emerge after consuming gluten and can affect both the digestive system and other areas of the body. It’s important to note that while these symptoms can indicate gluten intolerance, they may also be associated with other health issues, thus professional medical advice is recommended for an accurate diagnosis.
