"Comrade Old Liu, do we have a conclusion for Liu Lu's illness yet?" Wang Xiaoyan asked with some concern during lunch in the canteen.
Liu Banxia shook his head. "Not yet. We're trying to figure out which diagnostic direction to take. We're quite perplexed at the moment, as all potential causes seem plausible but not definitive."
"Oh... what can we do then? Even you can't figure it out?" Wang Xiaoyan sighed.
Liu Banxia gave her a wry smile. "I need some clear indicators before I can form a tentative hypothesis and perform the corresponding examinations."
"Considering her current symptoms, we think the problem might stem from somewhere within her digestive system—possibly her small intestine's absorption function or her stomach's digestive function."
"But both of these diagnostic procedures are somewhat invasive. Simpler tests, like an intestinal barium meal, can only provide a general overview and may not be entirely accurate."
