Pathway to Prevention of Type 1 Diabetes (T1D)

Condition: Diabetes
Investigator: Robin Goland, MD
Status: Currently Recruiting
A future without Type 1 Diabetes (T1D) starts with you. Get screened! Thanks in large part to T1D family members, we understand T1D as a disease that progresses in three distinct stages. This new definition in conjunction with TrialNet's Pathway to Prevention screening, allows for earlier detection and intervention.

We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate…
