Tirzepatide Overview
Tirzepatide is a dual GIP/GLP-1 receptor agonist. It targets two receptors to lower blood sugar and help with weight loss. The FDA approved it for type 2 diabetes in 2022. It shows promise in weight management.
How It Works
Tirzepatide mimics incretin hormones, which help control glucose levels. By targeting both GIP and GLP-1 receptors, it boosts insulin release and lowers glucagon. This dual action improves blood sugar control and aids weight loss by increasing fullness and slowing stomach emptying. This dual approach may make tirzepatide more effective than drugs that only target GLP-1.
Pros
- Targets two receptors, possibly offering better results.
- Significant weight loss seen in clinical trials.
Cons
- Newer on the market, so long-term effects are still unknown.
- Common side effects include nausea and diarrhea.

Semaglutide Overview
Semaglutide is a GLP-1 receptor agonist. It comes as an injection (Ozempic, Wegovy) and a tablet (Rybelsus). It lowers blood sugar and helps with weight loss. Semaglutide has been around longer and has a well-known safety profile.
How It Works
Semaglutide mimics the GLP-1 hormone. This hormone boosts insulin release after meals. It also lowers glucagon, reducing liver glucose production. By slowing stomach emptying, semaglutide increases fullness, aiding weight management. It is available in both injectable and oral forms, offering flexibility for patients with different needs.
Pros
- Available in both injection and oral forms, offering options.
- Approved for both diabetes and weight management.
Cons
- May cause stomach issues like nausea and vomiting.
- Some users report headaches and tiredness.
