Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, which helps the body to regulate its glucose levels and suppress appetite. GLP-1 is an enzyme that helps the pancreas release insulin when needed, especially after you eat, reducing your blood sugar levels. Semaglutide also reduces appetite by increasing satiety hormones like cholecystokinin (CCK) and glucagon-like peptide 1 (GLP-1), in addition to lowering the hormone ghrelin, which triggers hunger.
Semaglutide VS. Phentermine
Semaglutide and phentermine are both prescribed for weight loss. However, semaglutide is an injectable medication that controls appetite whereas phentermine is an oral pill that works as a stimulant to increase metabolism and reduce calorie intake. While phentermine is typically used for short-term weight loss, semaglutide is usually prescribed for long-term use. Semaglutide has been shown to have fewer side effects than phentermine and may be more effective at helping people achieve sustained weight loss.
