What is it?
Tirzepatide is a once-weekly injectable medication designed to aid in weight loss and improve blood sugar control, especially in people with type 2 diabetes. It belongs to a new class of drugs that mimic two gut hormones—GLP-1 and GIP—making it highly effective for appetite regulation, insulin sensitivity, and metabolic balance.
How it Works
Tirzepatide is a dual agonist of the GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors. These hormones naturally occur in the body and are involved in controlling blood sugar levels and hunger. By activating both receptors, Tirzepatide:
-
Increases insulin secretion when blood sugar is high
-
Reduces glucagon (a hormone that raises blood sugar)
-
Slows gastric emptying, helping you feel full longer
-
Reduces appetite and calorie intake

Dosage / Cycle
-
Starting dose: 2.5 mg once weekly
-
Gradually increased every 4 weeks to 5 mg, 10 mg, or up to 15 mg weekly depending on tolerance and goals

Conclusion
Tirzepatide is a groundbreaking option for those looking to lose significant weight, manage type 2 diabetes, or improve metabolic health. Its dual action on GLP-1 and GIP receptors offers superior appetite control and fat loss compared to older GLP-1-only medications. While highly effective, it should be used under guidance, especially when titrating doses.
