Mounjaro (Tirzepatide) for Type 2 Diabetes: How It Works

Introduction: What is Mounjaro (Tirzepatide)?

Mounjaro is the brand name for tirzepatide, a breakthrough injectable medication approved by the FDA in 2022 for treating type 2 diabetes. What makes Mounjaro unique is its dual-action mechanism targeting two hormones—GLP-1 and GIP—that regulate blood sugar, digestion, appetite, and metabolic health.

Mounjaro has shown superior glucose-lowering and weight-loss effects compared to older diabetes medications, offering hope to patients struggling with blood sugar control and obesity.

At Medical Wellness Clinic in Chula Vista, Mounjaro is offered as part of a personalized diabetes management plan to help patients improve metabolic health with expert supervision.

What Makes Mounjaro Different from Other Diabetes Drugs?

Mounjaro is the first medication in the class of dual GIP and GLP-1 receptor agonists.

GLP-1 (Glucagon-Like Peptide-1) functions:

• Increases insulin secretion

• Suppresses appetite

• Slows stomach emptying

GIP (Glucose-Dependent Insulinotropic Polypeptide) functions:

• Enhances insulin response

• Supports metabolic improvements

• May further support weight loss

By acting on both receptors, Mounjaro offers broader metabolic benefits than GLP-1–only medications like Ozempic or Wegovy.

FDA Approval: Mounjaro for Type 2 Diabetes

Mounjaro was approved by the FDA in May 2022 for adults with type 2 diabetes as an addition to diet and exercise.

Key Benefits:

• A1C reduction often exceeds 2%

• Weight loss of 15–22% in some patients

• Lower risk of hypoglycemia versus insulin

• Weekly dosing for convenience

How Mounjaro (Tirzepatide) Works in the Body

Mounjaro mimics both GIP and GLP-1 hormones, helping:

• Stimulate insulin when blood sugar is high

• Reduce glucagon (which raises blood sugar)

• Slow gastric emptying for longer fullness

• Reduce appetite and cravings

This dual hormone approach supports stable blood sugar, weight reduction, and better metabolic function.

Mounjaro Dosage & Administration

Mounjaro is administered via once-weekly subcutaneous injection with gradual dose escalation:

• Week 1–4: 2.5 mg

• Then: Increase to 5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg as tolerated

No mixing or measuring is required, making the pen convenient for home use.
