Question explored with the scientific record
Remove gall bladder
The short version: removing the gallbladder trades gallstone pain for a 1 in 7 chance of chronic diarrhea, and the evidence on long-term metabolic harm is missing.
The evidence here is thin and mostly about surgical technique and post-op diarrhea, not about whether you should have the surgery in the first place. One 2025 study of 3,385 gallstone patients found 14.2% developed post-cholecystectomy diarrhea, with younger patients under 35 hit hardest at 32% [2]. A 2015 review of 529 patients reported 76% complete symptom resolution but 12% got frequent diarrhea and 6% got recurrent belly-button infections [1]. Neither study compared surgery to watchful waiting or dietary management, which is the comparison that would tell you whether the surgery is worth it.
The 2004 neurology study used cholecystectomy patients as a control group for bariatric surgery and found 3% developed peripheral neuropathy after gallbladder removal [3]. That is a real number but the study was not designed to track it, so it is a signal, not a proof.
| Outcome | Rate | Source |
|---|---|---|
| Complete symptom resolution | 76% | [1] |
| Post-op diarrhea (all ages) | 14.2% | [2] |
| Post-op diarrhea (under 35) | 32.2% | [2] |
| Frequent diarrhea | 12.1% | [1] |
| Peripheral neuropathy | ~3% | [3] |
| Incision hernia | 0.3% | [1] |
No study in this evidence set compared surgery to no surgery. No study tracked long-term metabolic outcomes like bile acid malabsorption, fat-soluble vitamin deficiency, or changes in cholesterol metabolism beyond a tiny 8-patient pancreatic insufficiency study [5]. The 1991 editorial on lithotripsy noted that 72% of patients had biliary colic after stone fragmentation, meaning gallbladder removal does not eliminate all symptoms [4].
My call: the evidence does not establish that cholecystectomy is worth it for most patients, especially younger ones, because the 1-in-3 diarrhea risk under 35 and the complete absence of long-term metabolic safety data mean the burden of proof has not been met. Confidence: moderate, because the missing data is the finding.
