FAQ
- Do GLP-1 receptor agonists lower tuberculosis risk?
- An observational analysis found fewer TB diagnoses among people with type 2 diabetes using GLP-1 receptor agonists versus other diabetes drugs, but this is an association, not proof the peptide directly blocks infection.
- Why does diabetes raise tuberculosis risk?
- Long-term high blood sugar weakens macrophages, the immune cells that normally surround and destroy the TB bacterium, making infection more likely to take hold and progress.
- Are semaglutide, tirzepatide, and retatrutide the same class of compound?
- No. Semaglutide targets only the GLP-1 receptor, tirzepatide targets GLP-1 and GIP receptors, and retatrutide targets GLP-1, GIP, and glucagon receptors, so effects aren't interchangeable in research.
