Understanding Different Types of Blood Sugar Monitors
Not all glucose meters are created equal. The market is broadly categorized into standard meters and continuous glucose monitoring (CGM) systems. Understanding the pros and cons of each can help you decide what aligns best with your lifestyle and medical needs.
Standard Blood Glucose Meters (BGMs)
- Traditional and Common: These are the most widely used meters. They require a small blood sample obtained through a finger prick, and results are displayed on the screen.
- Affordable and Accessible: BGMs are generally more affordable and widely available.
- Disadvantages: Provide only a snapshot reading of your blood sugar level at a specific time. Multiple daily tests are required to get a clear picture.
Continuous Glucose Monitoring (CGM) Systems
- Real-time, Constant Monitoring: These systems use a small sensor inserted under the skin to continuously monitor glucose levels in interstitial fluid.
- Detailed Insights: Provide continuous data, graphs, and alerts, allowing you to spot patterns and make real-time adjustments to your therapy.
- Higher Cost: CGMs typically have a higher initial cost and require regular sensor replacement.
- Suitable for Intensive Management: Ideal for individuals on intensive insulin therapy and those who need to maintain tight blood sugar control.
| Monitor Type | Features | Pros | Cons | Best for |
|---|---|---|---|---|
| Standard BGM | Finger prick, discrete readings, strips | Affordable, widely available, user-friendly | Only provides snapshot readings, Requires multiple finger pricks | Individuals managing type 2 diabetes, people who are cost-conscious |
| Continuous Glucose Monitor (CGM) | Sensor under skin, real-time, constant monitoring | Provides trends and patterns, fewer finger pricks needed | Higher initial cost, ongoing cost, requires maintenance | Individuals on intensive insulin therapy, people requiring continuous blood sugar monitoring |

Govindarajan Rajagopalan, Ph.D., Yogish C. Kudva, MBBS, and Joe Murray, M.D., discuss research showing that the intestinal microbiome plays a large role in the development of Type 1 diabetes. Now, researchers at Mayo Clinic have is 112 high for blood sugar demonstrated that gluten in the diet may modify the intestinal microbiome, increasing incidences of Type 1 diabetes. These researchers demonstrated that caffeine affect blood sugar mice fed a gluten-free diet had a dramatically reduced incidence of Type 1 diabetes. These mice were a non-obese diabetic mice, or mice that grow to develop Type 1 diabetes. The gluten-free diet worked to protect the mice against Type 1 diabetes. When the researchers added gluten back into the diets of mice it reversed the protective effect the gluten free diet had provided. There also was a measurable impact of the gluten on the bacterial blood sugar 98 mg dl flora of the mice that might be one way in which gluten could affect the risk for diabetes.
