Yes, GLP-1 medicines can have specific side effects that you should be aware of. Common side effects include nausea, vomiting, and diarrhea, especially when starting the medication or increasing the dose. Some individuals may also experience stomach pain or loss of appetite. These symptoms often lessen over time as your body adjusts to the medication. However, if you experience severe side effects such as persistent vomiting, severe abdominal pain, or symptoms of pancreatitis (like severe pain in the upper abdomen, nausea, and vomiting), it's crucial to seek medical attention immediately. Always discuss any side effects you experience with your healthcare provider.
