From the Guidelines
I strongly recommend that patients with gallstones (cholelithiasis) taking GLP medication, such as semaglutide, exercise caution and closely monitor their condition, as these medications can increase the risk of acute gallbladder disease, according to the most recent study 1. When considering the management of gallstones in patients taking GLP-1 medications, it's essential to weigh the benefits of the medication against the potential risks to the gallbladder. The study 1 highlights that semaglutide, a GLP-1 analog, may cause nausea, vomiting, diarrhea, and other gastrointestinal side effects, which could exacerbate gallstone symptoms. Furthermore, the study notes that patients with a history of cholelithiasis should use caution when taking semaglutide.
Key Considerations
- The medication's mechanism of action, which slows stomach emptying and reduces gallbladder contractions, may worsen gallstone issues 1.
- Patients should be aware of the potential symptoms of gallstone complications, such as severe abdominal pain, fever, or yellowing of the skin, and seek immediate medical attention if they occur.
- Maintaining a low-fat diet and staying well-hydrated may help reduce gallstone irritation.
Management Approach
- Closely monitor the patient's condition and adjust the medication dosage as needed to minimize the risk of gallstone complications 1.
- Consider alternative treatments, such as ultrasound imaging to reassess the gallstones, and discuss the patient's case with a gastroenterologist if symptoms persist.
- The connection between GLP-1 medications and gallstones is related to the medication's effect on digestive processes, which can reduce gallbladder emptying and potentially allow bile to become more concentrated and form stones or aggravate existing ones 1.
From the Research
Recommendations for Patients with Gallstones Taking GLP Medication
- Patients with gallstones (cholelithiasis) taking GLP (Glucagon-like peptide) medication should be aware of the potential increased risk of bile duct and gallbladder disease, as suggested by studies 2, 3.
- The use of GLP-1 analogues has been associated with an increased risk of bile duct and gallbladder disease, including cholecystitis and cholelithiasis, compared to other antidiabetic drugs 2.
- GLP-1 receptor agonists may delay gallbladder refilling and counteract postprandial cholecystokinin-mediated gallbladder contraction, which could potentially increase the risk of gallstone formation 4.
- Liraglutide, a GLP-1 receptor agonist, has been shown to increase serum levels of deoxycholic acid, which may alter the intestinal microbiome and potentially contribute to gallstone formation 5.
- Exogenous GLP-2 has been found to counteract exogenous cholecystokinin-induced gallbladder contraction in healthy men, suggesting a possible therapeutic potential for GLP-2 as a relaxing modulator of gallbladder smooth muscle tone 6.
- Metformin, on the other hand, may play a protective role in cholelithiasis by modulating the levels of Neurotrophin-3 (NT-3) and Interleukin-10 receptor subunit beta (IL-10RB) 3.
Key Considerations
- Patients with gallstones taking GLP medication should be monitored closely for signs of bile duct and gallbladder disease, such as abdominal pain, jaundice, and fever.
- The potential benefits and risks of GLP medication should be carefully weighed, and alternative treatments should be considered if necessary.
- Further research is needed to fully understand the relationship between GLP medication and gallstone formation, as well as the potential therapeutic applications of GLP-2 in the treatment of gallbladder disease.
