Celiac disease. This image shows a comparison between healthy intestinal villi and those affected by celiac disease. In this illustration, elongated normal villi contrast with flattened structures. Moreover, the figure highlights a reduced absorption surface. Together, these changes impair intestinal function.
Celiac disease is an autoimmune disorder affecting the small intestine. Additionally, it is triggered by gluten intake found in wheat, barley, and rye. However, in genetically predisposed individuals, the immune system reacts abnormally. As a result, inflammation develops.
The main function of intestinal villi is nutrient absorption. Nevertheless, in this condition, this function becomes impaired. Furthermore, villous atrophy reduces the available surface. Consequently, nutrient absorption decreases significantly.
The origin involves genetic and environmental factors. Moreover, gluten exposure triggers a persistent immune response. Therefore, progressive damage occurs in the intestinal lining. Additionally, digestive balance is disrupted.
Nutrient transport is severely affected. In a healthy intestine, nutrients enter the bloodstream efficiently. In contrast, damaged mucosa prevents proper absorption. As a result, nutritional deficiencies may appear.
Key processes include chronic inflammation, autoimmune response, and villous atrophy. Moreover, symptoms include diarrhea, abdominal pain, weight loss, and fatigue. However, some individuals may show mild or atypical symptoms.
Regulation requires early diagnosis. Additionally, serological tests and intestinal biopsy are essential. Furthermore, treatment consists of a strict gluten-free diet. Together, these measures allow intestinal recovery.
In conclusion, celiac disease affects nutrient absorption and digestive health. With proper treatment, symptoms improve, and complications are prevented.
