Final answer:
The most common dietary modification for a woman with celiac disease who is decompensating is to follow a strict gluten-free diet and possibly take nutritional supplements to correct nutrient deficiencies.
Step-by-step explanation:
The most common dietary modification for a woman with celiac disease (CD) who shows signs of decompensation is to maintain a strict gluten-free diet. Gluten is a protein found in wheat, barley, and rye, and consumption can cause damage to the small intestine in individuals with celiac disease, leading to symptoms and further health complications. Alongside adhering to a gluten-free diet, the patient may also require nutritional supplements to address any nutrient deficiencies resulting from malabsorption.
It's important that the individual with CD receives guidance from a registered dietitian or healthcare provider to ensure that the gluten-free diet is well-balanced and that other potential issues, such as lactose intolerance, are also managed appropriately. Regular follow-up and monitoring of nutrient levels and intestinal healing are essential parts of the overall treatment plan for managing celiac disease.
