GLP-1 medicines work by enhancing insulin secretion in response to meals, which helps regulate blood sugar levels and can reduce fluctuations throughout the day. They also slow gastric emptying, leading to a more gradual rise in blood glucose after eating. This can be especially beneficial for individuals with type 2 diabetes. However, it’s still important to monitor your blood sugar regularly and follow your healthcare provider's advice to achieve optimal control. If you notice significant fluctuations, discuss this with your GP to adjust your treatment plan as needed.
