Rationale for change
I would change the card to something like:
Crohn disease is associated with calcium oxalate kidney stones due to increased **intestinal absorption** of [...].
I think that wording is clearer than “increased **levels** of [...]”, because “levels” could make you think of fatty acids, serum calcium, bile acids, etc.
For instance, I thought [...] was referring to "fatty acids" since you cannot absorb them well if the terminal ileum was damaged, leading to enteric hyperoxaluria... but this card wanted a more "superficial" answer.

Extra
- Physiologically, oxalate is bound by calcium in the gut, preventing its absorption
- In inflammatory bowel disease (e.g., Crohn's), malabsorption of fats leads to calcium binding to fats instead of oxalate, allowing oxalate to be freely absorbed
- This can also occur in other malabsorptive conditions (e.g., gastric bypass)
