Dr. Jeff Colburn, an expert in diabetes management and virtual care, shares valuable insights on continuous glucose monitors (CGMs) and insulin management. He discusses how to interpret CGM data, addressing issues such as overnight hypoglycemia and post-prandial highs. The conversation also highlights personalized medication strategies and the integration of GLP-1 agonists and SGLT-2 inhibitors. Colburn emphasizes the importance of patient education and adjusting treatment plans based on individual glucose patterns, making diabetes care more accessible and effective.
Continuous glucose monitors (CGMs) have improved accessibility, allowing insurance coverage for patients using basal insulin, enhancing diabetes management.
The data from CGMs help healthcare providers identify glucose trends, enabling personalized adjustments to insulin regimens for better patient outcomes.
Educating patients on hypoglycemic symptoms and medication adjustments is crucial for preventing dangerous drops in blood sugar, especially overnight.
Deep dives
The Importance of Continuous Glucose Monitors (CGMs)
Continuous glucose monitors (CGMs) have recently become more accessible due to changes in Medicare and Medicaid eligibility. Patients using basal insulin alone can now get insurance coverage for these monitors, which provide real-time data on glucose levels. This technology is especially beneficial for patients who struggle with hypoglycemia, as the CGMs can alert them to low levels, enabling timely interventions. Furthermore, using CGMs simplifies the management of diabetes, allowing healthcare providers to review patterns over time and make informed treatment adjustments.
Understanding CGM Data Patterns
The data provided by CGMs enables healthcare providers to observe glucose trends, illustrating how blood sugar levels fluctuate throughout the day. For example, a patient might have normal fasting glucose levels but experience postprandial hyperglycemia after meals, which can be effectively identified with CGM usage. This insight allows for targeted interventions, such as adjusting medications based on when glucose levels spike. Additionally, patients can see how different foods impact their blood sugar, potentially leading to better dietary choices.
Troubleshooting Hypoglycemia
When blood sugar readings indicate nocturnal hypoglycemia, adjustments to medication regimens are often necessary. It's essential to investigate lifestyle factors that could be contributing to these lows, such as meal timings and carbohydrate intake. Patients may need to reduce their basal insulin dosage or alter when they administer their medications to prevent these dangerous drops in blood sugar during the night. Healthcare providers should also educate their patients on the importance of recognizing hypoglycemic symptoms and responding appropriately.
Managing Postprandial Hyperglycemia
To combat postprandial hyperglycemia, healthcare providers may suggest various medication options, including GLP-1 receptor agonists and SGLT2 inhibitors. Combining these medications with existing treatments can be effective, especially when a patient's daytime glucose levels are elevated after meals. Patients may not need to resort to multiple daily injections of insulin; instead, targeting their largest meals with prandial insulin can lead to better management with fewer daily injections. The key is to tailor the approach based on the individual patient's lifestyle and glucose patterns.
Integrating CGMs into Diabetes Care
As diabetes management evolves, integrating CGMs into routine care is becoming a priority for healthcare providers. These devices offer significant advantages over traditional finger-stick monitoring, including real-time alerts and comprehensive data analysis. Using CGMs can decrease the burden of diabetes management for both patients and providers, making it easier to identify trends and optimize treatment plans. By adapting workflows to include CGM data, healthcare professionals can enhance patient outcomes and tailor interventions based on more accurate glucose monitoring.

Step up your diabetes game! Learn the ins and outs of continuous glucose monitors (CGM) including key features, what and how to order, interpreting CGM data (time in range, time above range, etc.), and how to make adjustments to a patient’s insulin regimen, aka “insulin pattern matching”. We discuss common scenarios including overnight hypoglycemia, exercise-induced hypoglycemia, post-prandial hyperglycemia, what to do when the patient runs high all the time, and how to incorporate GLP1 agonists and SGLT2 inhibitors into a patient's regimen. Returning guest and Paul’s favorite frenemy, Dr. Jeff Colburn (VCU Health) returns!
