Which condition involves dark, foul-smelling stools and indicates possible malabsorption?

The indication of dark, foul-smelling stools that are associated with malabsorption points to cystic fibrosis. This genetic disorder primarily affects the lungs and digestive system due to the production of thick, sticky mucus. In the gastrointestinal tract, this can lead to blockages that interfere with the normal absorption of nutrients, resulting in steatorrhea, which is characterized by oily, foul-smelling stools. Such symptoms arise because the malabsorption prevents fats from being properly digested and absorbed.

Additionally, cystic fibrosis can affect the pancreas, leading to pancreatic enzyme insufficiency. This lack of enzymes means that even when food is consumed, the body cannot adequately break down and absorb essential nutrients, contributing to the malodorous stool characteristics associated with this condition.

While gluten intolerance, gastroesophageal reflux, and lactose intolerance can also lead to issues with digestion and absorption, they do not typically present with dark, foul-smelling stools in the same way that cystic fibrosis does. Gluten intolerance is generally marked by bloating and diarrhea, but not specifically foul-smelling stools related to malabsorption. Gastroesophageal reflux primarily involves symptoms related to heartburn and regurgitation, and lactose intolerance usually presents with gas, bloating, and diarrhea but does
