Summary

This study looked at why people with type 1 diabetes often fail to sense dangerously low blood sugar (hypoglycemia). Researchers tested how opioid drugs like morphine and naloxone affect the body's ability to respond to low sugar. The goal was to better understand the problem, not to find a treatment. The study was terminated early and included 39 healthy volunteers without diabetes.
