HAVE A GREAT SUMMER

What are you plans for the summer?

Life presents built in opportunities to make a change or shift a mindset.

With school out, daylight hours lengthening, and cooling foods aplenty how can we redesign our daily habits to accommodate nature's shifts to better align with our health?

More to come...

CGM bros!

Continuous glucose monitors are amazing wearable devices that provide real-time insights into how food, movement, sleep and stress can impact your blood sugar levels. Even for our patients without insulin resistance or diabetes, GGMs have been an invaluable tool in our practice.

Some of the insights include:

• Glucose trends: Showing how levels change over time

• Impact of food: Identifying specific foods that cause spikes

• Effect of exercise: Demonstrating how activity influences glucose

• Stress responses: Highlighting how stress affects blood sugar

• Sleep patterns: Revealing nightly glucose fluctuations

• Medication efficacy: Assessing how well insulin or other medications work

• Time in range: Quantifying the percentage of time glucose stays within target

• Glucose variability: Showing the degree of fluctuations, indicating stability

• Hypoglycemic events: Alerting to dangerous low glucose levels

• Hyperglycemic events: Alerting to dangerous high glucose levels
