Medical Weightloss - Tirzepitide
Tirzepatide is a once-weekly injectable medication used to support blood sugar control and weight loss. It works differently than older medications because it activates two hormone receptors in the body instead of one.
Tirzepatide is the active ingredient in:
Mounjaro – FDA-approved for type 2 diabetes
Zepbound – FDA-approved for chronic weight management
How Tirzepatide Works
Tirzepatide is a dual GIP and GLP-1 receptor agonist. That means it mimics two natural gut hormones:
GIP (Glucose-dependent Insulinotropic Polypeptide)
GLP-1 (Glucagon-Like Peptide-1)
Together, they help:
✔ Increase insulin when blood sugar is high
✔ Reduce glucagon (which raises blood sugar)
✔ Slow stomach emptying
✔ Decrease appetite
✔ Improve feelings of fullness
Because it works on two pathways, it often leads to greater weight loss compared to older GLP-1 medications.

FAQ
Frequently Asked Questions
How does tirzepatide work in the body?
Tirzepatide is a once-weekly injectable that targets two key hormones (GIP and GLP-1) to help control appetite, regulate blood sugar, and support fat loss, making it easier to achieve lasting metabolic health.
How does tirzepatide help with weight loss?
It reduces appetite, increases fullness, slows stomach emptying, and helps regulate blood sugar — leading to decreased calorie intake and fat loss over time.
How much weight can I lose?
Results vary, but clinical studies show patients may lose 15–22% of their body weight over time when combined with lifestyle changes.
How often is it taken?
Tirzepatide is injected once weekly, under the skin (abdomen, thigh, or upper arm).
When will I see results?

Nausea
Constipation
Diarrhea
Decreased appetite

Yes. Tirzepatide works best when combined with healthy eating, movement, hydration, and lifestyle support. It is a tool — not a replacement — for long-term habits.
Who is a good candidate?
Adults with:
A BMI over 30
A BMI over 27 with weight-related conditions (such as high blood pressure or insulin resistance)
A medical evaluation is required to determine eligibility.
