Summary

This study aims to better understand why some people experience dangerously low blood sugar (hypoglycemia), especially after fasting. Researchers will admit 1,500 adults to the NIH Clinical Center for controlled fasting and a series of blood tests to measure insulin and other factors. The goal is to improve diagnosis and treatment for conditions like insulinoma, a tumor that causes excess insulin.
