- slow stomach emptying
Researchers first explored tirzepatide for type 2 diabetes.
Clinical trials showed something surprising:
People were also losing significant weight.
That led to separate approvals and brand names.
How Zepbound emerged

- Mounjaro — tirzepatide for diabetes
- Zepbound — tirzepatide for obesity and weight-related conditions
So culturally and medically:
- Doctors say tirzepatide.
- Pharmacies may label Zepbound.
- Patients hear both and get confused.
3. Emotional & Psychological Meaning
