10 year old with poor growth, poor appetite, recurrent chest infections and steatorrhea is likely to have
**Core Concept**
Pancreatic insufficiency is a condition characterized by the inability of the pancreas to produce sufficient digestive enzymes, leading to malabsorption of nutrients. This can manifest as steatorrhea (fatty stools), poor growth, and recurrent infections.
**Why the Correct Answer is Right**
The correct answer is likely related to cystic fibrosis (CF), a genetic disorder that affects the pancreas and other organs. CF leads to the production of thick, sticky mucus that clogs the pancreas, causing a deficiency in pancreatic enzymes. This results in malabsorption of fats, proteins, and carbohydrates, leading to steatorrhea, poor growth, and recurrent respiratory infections.
**Why Each Wrong Option is Incorrect**
* **Option A:** While celiac disease can cause malabsorption and steatorrhea, it is typically associated with abdominal pain, diarrhea, and weight loss, rather than recurrent chest infections.
* **Option B:** Gastroesophageal reflux disease (GERD) can cause poor appetite and growth in children, but it is not typically associated with steatorrhea or recurrent chest infections.
* **Option C:** Inflammatory bowel disease (IBD) can cause malabsorption and steatorrhea, but it is typically associated with abdominal pain, diarrhea, and weight loss, rather than recurrent chest infections.
**Clinical Pearl / High-Yield Fact**
Cystic fibrosis is a classic example of a genetic disorder that affects multiple organ systems, and it is essential to consider CF in the differential diagnosis of children with recurrent respiratory infections, malabsorption, and poor growth.
**Correct Answer:** C. Cystic fibrosis.
