At a cellular level, both the pill and the injection utilize the same active molecule (semaglutide) to mimic your bodys natural hormone (GLP-1), which slows gastric emptying to increase fullness, stimulates insulin release to manage blood sugar, and acts on the brain to reduce hunger and cravings
All anti obesity medications including semaglutide, tirzepatide, and liraglutide, may carry gastrointestinal adverse events such as abdominal pain, decreased appetite, and nausea, and they should be used under close medical supervision, particularly in individuals with a family medical history of thyroid cancer, or existing cardiovascular disease, chronic kidney disease, or risk of heart attack
While its a normal response, ensuring you are well-hydrated may help lessen the intensity
