GAP Trial Summary

This trial is comparing two different thresholds for when to start medical treatment for gestational diabetes mellitus (GDM). Pregnant women with GDM will be randomly assigned to start treatment when they reach at least 20% or 40% above the target goal for capillary blood glucose (CBG) levels. The investigators think that a lower threshold of 20% will lead to fewer obstetric and medical complications.

Who is the study for?
This trial is for pregnant women over 18 with gestational diabetes who can communicate in English and check their blood sugar at least twice a day. It's not for those with pre-gestational diabetes, fasting blood sugar >=126 mg/dL, post-meal levels >=200 mg/dL, or already on pharmacotherapy.Check my eligibility
What is being tested?
The GAP study is testing when to start insulin treatment for gestational diabetes by comparing two groups: one starts treatment if at least 20% of their blood glucose readings are high, the other waits until at least 40% are high.See study design
What are the potential side effects?
Insulin use may cause low blood sugar (hypoglycemia), which can lead to symptoms like dizziness, sweating, confusion and in severe cases unconsciousness. Some might experience injection site reactions.
