CGM-Based Glycemic Analysis After ESI

Starting soon

Conditions studied: Type 2 Diabetes (T2DM), Hyperglycemia, Radicular Pain, Spinal Stenosis, Intervertebral Disc Herniation

In brief

The goal of this clinical study is to learn how blood glucose levels change after an epidural steroid injection (ESI) with dexamethasone in adults. It will specifically compare the glycemic response between patients with type 2 diabetes and those without diabetes. The main questions it aims to answer are: Does the injection cause higher or longer-lasting blood glucose elevation in diabetic patients compared to non-diabetic patients? How do the mean glucose level and Time in Range (TIR) change after the injection in both groups? Researchers will compare a Type 2 Diabetes group to a Non-Diabetes group to see the differences in glycemic fluctuations using a continuous glucose monitoring (CGM) device. Participants will: * Wear a small CGM sensor on their arm for about 15 days to monitor blood glucose levels continuously * Receive an epidural steroid injection containing 5 mg of dexamethasone on Day 3 * Visit the clinic 3 times (Day 1, Day 3, and Day 15) for sensor attachment, the injection procedure, and data collection
