NCT ID NCT07241078
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a 12-week program that uses WhatsApp to teach people with type 2 diabetes and their family members how to manage the disease better. Participants get videos, quizzes, and weekly phone calls to improve self-care and blood sugar levels. The goal is to see if this approach lowers HbA1c and boosts family support compared to usual care.
