1. Usage: Semaglutide is primarily used to treat type obesity and/or diabetes. It's often prescribed when other oral diabetes medications or injectable insulins haven't provided sufficient blood sugar control.

​

2. Administration: Semaglutide is available in both once-weekly and once-daily formulations, allowing for flexibility in dosing. The once-weekly version is usually preferred for its convenience.

 

3. Weight Management: In addition to its role in managing blood sugar levels, semaglutide has been studied for its potential to aid in weight loss. 

 

 4. Side Effects: Common side effects of semaglutide include nausea, vomiting, diarrhea, and decreased appetite. These side effects tend to improve over time as the body adjusts to the medication. 

 

5. Mechanism of Action: Semaglutide works by binding to GLP-1 receptors, which are found on pancreatic beta cells. This stimulates the release of insulin in response to rising blood sugar levels. It also reduces the release of glucagon (a hormone that increases blood sugar) and slows down the emptying of the stomach.
