People whose gallbladder has been removed should not take bile salts; removing the gallbladder causes one problem: the loss of the bile-salt store (about 40 ml).

科学评估
可能错误 – 现有证据倾向于不支持该说法，但尚无定论。
证据确定性: 极低 – 任何评估都非常不确定。
1. 说法是什么？
Eat more fat after cholecystectomy.
2. 哪些内容可证实是正确的？
The gallbladder stores and concentrates bile; after removal bile flows continuously (basic physiology).
3. 哪些内容是错误或夸大的？
No evidence supports doubling fat intake (e.g. 200 g/day) after cholecystectomy, and the available indirect evidence points the other way: post-cholecystectomy diarrhoea occurred in 13.3% of patients and was linked to high-fat meals in two studies (A-ORG-09), and low-fat diets tended to improve bile-acid diarrhoea (I-ORG-132). The absorption percentages he cites are not sourced.
4. 哪些内容仍不明确？
Not systematically searched. In a second passage of the same video he says people without a gallbladder should not take bile salts and that removal causes only one problem, the loss of the bile store (about 40 ml). That the gallbladder stores bile is basic physiology; the volume he gives is plausible but was not checked against a source here. 'Only one problem' is an oversimplification: post-cholecystectomy diarrhoea occurred in 13.3% of patients in a systematic review (A-ORG-09). No evidence was searched on bile-salt supplements after cholecystectomy; we make no judgement on that advice.
5. 哪些研究支持该说法？
Only for the premise: I-ORG-133 (faecal fat slightly higher after cholecystectomy despite similar diets; small 1982 study). No evidence for the advice itself.
6. 哪些研究与该说法相矛盾？
A-ORG-09 (indirect): post-cholecystectomy diarrhoea 13.3%, associated with high-fat meals or not following a low-fat diet in two included studies. I-ORG-132 (indirect, very low certainty): fat reduction tended to improve bile-acid diarrhoea; in one study diarrhoea returned when fat intake was increased.
7. 对德国和欧洲而言情况如何？
Most cited cohorts are Scandinavian (Denmark, Sweden) and directly European; RCTs from the UK and Finland are directly transferable. Guidelines in Europe also emphasize defined indications (not verified here in detail).
8. 关于埃及的已知情况是什么？
No Egypt-specific data on rates or outcomes of tonsillectomy, cholecystectomy, hysterectomy, splenectomy or thyroid surgery were identified in this review.
9. 合理的实际结论是什么？
没有证据表明切除胆囊后多吃脂肪有帮助，而且对出现腹泻的人来说，这可能会加重腹泻。胆囊切除术后的饮食建议应由临床医生或营养师提供。
评估详情
- 证据确定性的依据
No trial has tested fat intake after cholecystectomy. All indirect evidence points against the advice: a systematic review found post-cholecystectomy diarrhoea in 13.3% and linked it to high-fat meals in two studies (A-ORG-09), and a systematic review of bile-acid diarrhoea found that reducing dietary fat tended to improve symptoms, with diarrhoea returning when fat was increased in one study (I-ORG-132, very low certainty, mostly ileal-resection patients). A small 1982 study found slightly higher faecal fat after cholecystectomy (I-ORG-133), which supports the premise but not the advice. Very low certainty because the evidence is indirect and small.

总体证据说明了什么？
基于上述研究的编辑评估——其本身并非研究结果。
哪种观点有更好的证据支持？
Fat digestion may be slightly less efficient after cholecystectomy, but no evidence supports eating more fat; the limited evidence on bile-acid diarrhoea points the other way (less fat, fewer symptoms).
为什么有些研究权重更大
No RCT exists; the direction of the indirect evidence is consistent against the advice.
因果关系是否已确立？ 尚未确立 No trials of fat intake after cholecystectomy.
仍存在的不确定性
Optimal diet after cholecystectomy.
合理的结论
The advice to double fat intake is unsupported and may worsen diarrhoea in susceptible people.
这是否取决于国家？
- 一般生物学效应
- Universal.
- 饮食习惯
- Butter and ghee are common in Egyptian cooking; a 200 g/day fat intake would be far above usual intakes in any population.

- 2026年10月25日 · 第 1 阶段 · 初始评估: 不明确 / 证据不足 (极低)
- 2026年10月26日 · 第 4 阶段（系统证据审查） · 评定结论已更改: 不明确 / 证据不足 (极低) → 可能错误 (极低)
Changed from UNCLEAR to POTENTIALLY_FALSE (certainty stays very low). The systematic review on bile-acid diarrhoea (I-ORG-132) adds to A-ORG-09: all available indirect evidence points against increasing fat intake (low-fat diets improve bile-acid diarrhoea; high-fat meals linked to post-cholecystectomy diarrhoea), while no evidence supports the advice. Evidence remains indirect and weak, so a stronger verdict is not justified.

通俗解释
Elawady 建议没有胆囊的人吃大约两倍的脂肪。确实，手术后脂肪消化的效率可能会略有下降。但没有研究显示多吃脂肪有帮助，而且有限的证据提示情况恰恰相反：约13%的人在切除胆囊后会出现腹泻，而少吃脂肪往往能缓解这类腹泻。因此，这一建议很可能是错误的，尽管还没有试验直接检验过它。
