Dietitian support may cut insulin need in pregnancy diabetes
NCT ID NCT06127823
First seen Jun 25, 2026 · Last updated Jul 08, 2026 · Updated 4 times
Summary
This study tests whether intensive dietary counseling from a dietitian can help women with gestational diabetes control blood sugar without needing insulin. 214 women will be randomly assigned to either intensive nutrition support or standard care. The main goal is to see if more women can manage with diet alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dietary counselling
- What this could lead to
- If it works, this could show that intensive dietary support reduces the need for insulin in gestational diabetes, improving maternal and child outcomes.
- What could go wrong
- This is a single-center trial with 214 participants, so results may not apply broadly. The intervention is behavioral, and outcomes depend on adherence.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Newly diagnosed women with GDM referred to Department of Obstetrics Herlev Hospital * Women diagnosed with GDM based on 2-hour OGTT plasma glucose value ≥ 9.0 mmol/l * Women diagnosed with GDM based on at least 2 plasma glucose measurements above targets (either pre-prandial ≥6.0 mmol/l, or 2-hours postprandial ≥8.0 mmol/l) * GA at GDM diagnosis ≤ 34 * Women with an estimated probability of ≥20% for initiating insulin treatment during pregnancy. The estimated probability is based on a logistic regression model developed at SDCC and includes the following variables: prepregnancy BMI, GA at GDM diagnosis, and HbA1c at GDM diagnosis. In cases where HbA1c has not been measured during the initial visit with the dietitian (screening visit), prepregnancy BMI, GA at the time of diagnosis and 2H OGTT will be used to estimate the probability of initiating insulin therapy. * Provided voluntary written informed parental consent in Danish or English or after translation by an interpreter for non-Danish and non-English speaking parents Exclusion Criteria: * Bariatric surgery * Other intercurrent illness (e.g., cancer, ulcerative colitis) as judged by medical experts * Uncontrolled medical issues, as judged by medical experts * Concomitant participation in other clinical trials that could interfere with the INTENSE- GDM Trial as evaluated by the principle investigator * Unable to understand the informed consent/procedures regardless of spoked language
