What is a common physical characteristic of the abdomen in clients with celiac's disease?

In clients with celiac disease, a common physical characteristic of the abdomen is distension, often accompanied by increased flatus (gas). This distention occurs as a result of malabsorption, inflammation of the intestinal lining, and the presence of undigested food substances that ferment in the intestines. When gluten is ingested, it triggers an immune response that damages the lining of the small intestine, leading to inflammation and a buildup of gases. The combination of these factors results in a bloated appearance of the abdomen, which can often be palpated as it may feel tense or swollen.

Other options are less representative of the typical abdominal presentation in someone with celiac disease. A sunken and rigid abdomen may suggest malnutrition or acute conditions that are not specifically tied to celiac disease. A flat and normal abdomen would not align with the common symptoms experienced by someone with malabsorption. Finally, while the abdomen may be tight and painful during a flare-up due to inflammation, this is not the most common or distinguishing characteristic that would be observed consistently and generally in individuals with celiac disease.
