Before starting GLP-1 therapy, it's essential to have a thorough discussion with your GP. You should inform them about any existing medical conditions, current medications, and allergies. This is crucial as GLP-1s can interact with other drugs and may not be suitable for everyone. Additionally, understanding the potential side effects and the importance of lifestyle changes is vital. Your GP can help you set realistic expectations regarding weight loss and overall health improvements. Don’t hesitate to ask questions and express any concerns you have; your healthcare team is there to support you.
