Gallstones and GLP-1 Medicines: What the Evidence Says
Gallbladder issues — including gallstones — are recognised as a relevant consideration when using GLP-1 and dual GIP/GLP-1 receptor agonist medicines like semaglutide and tirzepatide. Rapid weight loss of any kind can influence gallstone formation, and GLP-1 medicines have been associated with gallbladder-related events in clinical data. The electronic Medicines Compendium (eMC) patient information for both medicines lists gallbladder problems among effects to be aware of.
This does not automatically mean these medicines cannot be used by anyone with a history of gallstones, but it does mean your prescriber needs to know about your gallbladder history before and during treatment. They will weigh your individual circumstances, the nature of your gallstones, and any symptoms you experience.
Symptoms that need prompt attention
If you are already taking a weight loss injection and experience any of the following, contact your healthcare professional promptly — do not wait for a routine appointment:
- Sudden or severe pain in your upper abdomen or right side
- Pain that spreads to your shoulder or back
- Nausea or vomiting alongside abdominal pain
- Yellowing of the skin or eyes
- Dark urine or pale stools
These can be signs of gallbladder or bile duct complications that require urgent medical assessment. GLP Trackr helps you record symptoms as they happen so you have an accurate log to share with your prescriber — but it is not a substitute for seeking care when something feels serious.
For more detail on how weight loss injections work and what to expect, including other commonly reported side effects and safety considerations, see our main guide. You may also find our overview of taking weight loss injections with gallstones useful for a broader look at this topic.

Tracking Your Journey With GLP Trackr When Health History Matters
When you have a condition like gallstones, keeping a clear, detailed record of how you feel day to day becomes especially valuable. GLP Trackr's side-effect tracking feature lets you log symptoms — including any abdominal discomfort, nausea, or digestive changes — with a time and date stamp, so you can see whether patterns emerge and bring a clear picture to your prescriber appointments rather than relying on memory.
Alongside symptom logging, the app's daily check-in captures your mood, energy, and general wellbeing each morning in under a minute. Over time, this builds a personal record that can genuinely support more informed conversations with your healthcare team — the kind of detail that is hard to recall weeks after the fact.
If your prescriber has confirmed it is appropriate for you to continue your injections, the app's injection-site rotation tracking and dose logging also help you stay consistent with your weekly schedule, so nothing gets missed or muddled.
Always follow the guidance of your prescriber or doctor — they know your full medical history, including your gallbladder situation, and are the right person to make any decisions about your treatment. GLP Trackr is here to support your tracking and help you stay informed, not to replace clinical advice. If you have any concerns about the cost or logistics of your treatment, our guide on understanding weight loss injection costs covers what people typically consider.
