People commonly use that to indicate throwing up. Which would be expected in a stomach bug.
Of course, he could have been indicating a suspicion that she's making herself throw up on purpose, (bulimia). If you think that might be true, or have seen any signs that she's doing that, tell your parents, but let them handle it. You getting involved is probably not a great idea right now.
