If you experience gastrointestinal side effects from GLP-1 medicines, such as nausea, vomiting, or diarrhea, it's important to communicate with your GP. These side effects can be common when starting treatment, but they should gradually improve over time. Your doctor may recommend adjustments in dosage or provide tips on managing these symptoms, like taking the medication with food or slowing down the titration process. Do not stop taking the medication without consulting your healthcare provider first, as they can help ensure you continue to benefit from the treatment while managing side effects effectively.
