Which condition typically presents with diarrhea as a symptom?

Chronic pancreatitis often presents with diarrhea due to the pancreas' inability to properly produce digestive enzymes. In this condition, the inflammation of the pancreas leads to malabsorption of nutrients, as essential enzymes that break down carbohydrates, proteins, and fats are deficient. As a result, individuals may experience steatorrhea, which is characterized by fat-laden, loose stools, ultimately resulting in diarrhea.

In contrast, conditions such as Meckel's diverticulum, appendicitis, and pancreatic cancer may present with a variety of gastrointestinal symptoms, but diarrhea is not a typical primary symptom associated with these conditions. Meckel's diverticulum can cause complications like obstruction or bleeding, but does not generally lead to chronic diarrhea. Appendicitis primarily causes abdominal pain and can lead to nausea and vomiting, but diarrhea is not a hallmark symptom. Similarly, pancreatic cancer can cause weight loss, jaundice, and pain, but diarrhea is less frequently a primary feature unless there's significant disruption to digestive function, which is more marginal than what is observed in chronic pancreatitis.
