Wearable sensor could unmask hidden blood sugar chaos in stomach paralysis
NCT ID NCT06046833
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This pilot study is testing whether a real-time continuous glucose monitor (FreeStyle Libre 3) can reveal differences in blood sugar patterns between people with diabetes who have gastroparesis (delayed stomach emptying) and those without it. About 50 adults with type 1 or type 2 diabetes will wear the sensor, which measures glucose every minute, and drink a nutritional shake to see how their blood sugar responds. The goal is to understand how gastroparesis affects glucose control, which could lead to better management strategies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FreeStyle Libre 3 continuous glucose monitoring sensor and a nutritional drink (Boost Plus)
- What this could lead to
- If successful, this could improve how blood sugar is managed in people with diabetes and gastroparesis, potentially reducing dangerous glucose swings.
- What could go wrong
- This is a small pilot study, so results may not apply to everyone. The sensor and drink may not fully capture real-world conditions, and no treatment is being tested.

Inclusion Criteria: * Over the age of 18 years. * Hemoglobin A1c ≤11% within the last 6 months. * Patients with diagnosis of type 1 Diabetes or type 2 Diabetes for at least one year. * Normal thyroid-stimulating hormone (TSH) within the last year. * No episodes of diabetic ketoacidosis (DKA), Hyperosmolar Hyperglycemic Status (HHS), or hypoglycemia in the past 2 weeks requiring ER visit or hospitalization. * Symptoms of gastroparesis have been present for at least the past 3 months, in patients with gastroparesis. * In patients with gastroparesis, documented delayed gastric emptying on scintigraphy and/or wireless motility capsule (Smart Pill) as defined by greater than 10% retention at 4 hours or greater than 4-hour gastric transit time (GTT) in the past five years. * Patients using a Smartphone (iPhone or Android) compatible with LibreView App. Exclusion Criteria: * Hemoglobin A1c of \>11% at enrollment. * Advanced chronic kidney disease (serum creatinine of \>2 mg/dL or estimated glomerular filtration rate (eGFR) \<30mL/min/1.73m² using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula). * Advanced and significant cardiovascular disease or unstable angina. * Advanced liver disease that may affect glucose profiles. * Post-transplant patients. * History of gastric surgery. * Patients with symptoms secondary to celiac disease (e.g. diarrhea, nausea, vomiting, abdominal pain) at the time of the enrollment. * Pregnancy or women of reproductive age group not taking adequate precautions for pregnancy for 28 days. * Patients on steroids or immunomodulators or chemoradiation that might affect glucose profiles. * Patients on opiates or glucagon-like peptide-1 (GLP-1) agonists (Ozempic, Wegovy, Mounjaro, Trulicity). If previously taking these medications, patients can be enrolled after 2 weeks of the last dose. * Patient on recreational or illicit drugs (i.e., marijuana, opiates, cocaine, etc.). * Patients on motility medications such as Reglan (Metoclopramide), Motegrity (Prucalopride), Cisapride, Domperidone, Erythromycin. If previously taking any of these medications, patients can be enrolled after 1 week of the last dose. * Clinically significant abnormalities on upper GI endoscopy. * Presence of imaging evidence of gastric or intestinal obstruction. * Patient previously participated in the study.
