Continuous Glucose Monitoring (CGM) is a game-changer for managing blood glucose levels and refining dietary habits, offering a non-invasive solution for patients.

The connection between our diet and overall health is deeply rooted in both ancient wisdom and modern science. Specifically, high carbohydrate consumption negatively impacts blood sugar levels, leading to various health complications. On the other hand, proteins and healthy fats exert a lesser effect on glucose levels.

Research indicates that our bloodstream can handle only about one teaspoon of sugar at any moment. When levels exceed this threshold, the body redirects the excess to muscle and fat cells. Although I've discussed these processes in previous articles, I will not elaborate further here.

In essence, if these cells struggle to absorb glucose properly, it can lead to severe conditions such as insulin resistance, metabolic syndrome, prediabetes, and eventually diabetes.

If left untreated, advanced type II diabetes can result in serious complications, including kidney damage, vision impairment, heart disease, dementia, and even amputations.

To maintain optimal health, one essential tool we must utilize effectively is Continuous Glucose Monitoring (CGM).

While anyone can benefit from tracking their blood glucose as a preventative measure, this technology is particularly crucial for individuals with diabetes or prediabetes. Below, I will outline the significance of CGM by examining its functions, effects, and broader implications.

Though we might not need CGM permanently, it is vital to initially understand how different foods affect our blood sugar levels, identify those that spike our glucose, and eliminate them from our diets. Regular monitoring through CGM serves as a valuable resource for making informed dietary choices and managing blood glucose proactively.

You may have heard of the Hawthorne Effect, which describes how individuals often change their behavior when they know they are being observed. In this context, CGM acts like an external observer, prompting users to make healthier food choices and better regulate their consumption.

Research has shown a direct correlation between higher blood glucose levels and increased mortality rates. For instance, studies published in the Journal of the Royal Society of Medicine have linked hyperglycemia upon hospital admission to elevated mortality risks, particularly for patients with myocardial infarction or acute coronary syndromes.

A 2021 review by the American Diabetes Association highlights that "the advent of reliable continuous glucose monitoring (CGM) systems marks a significant advancement in diabetes management and research." Most current CGM systems are designed for use over 7 to 14 days, utilizing a wire-tipped glucose oxidase sensor inserted into the subcutaneous tissue to measure glucose levels in interstitial fluid.

Researchers noted a lack of published data on the historical and recent use of CGM in clinical trials for pharmacological treatments of diabetes. They analyzed 2,032 clinical trials involving 40 antihyperglycemic therapies on the market, with study start dates between January 1, 2000, and December 31, 2019.

Moreover, CGM is advantageous for identifying insulin resistance and offers insights that are often more meaningful than A1C results when practitioners evaluate overall trends and averages.

This technology can be an invaluable resource for family physicians aiming to support their patients in preventing diabetes.

Given the significant advantages and minimal risks associated with CGM for these patients, I expect to see clinical trials conducted soon. I believe this is a straightforward decision, but we must advocate for it as a society. Every voice matters in driving progress.

Currently, CGM is available only through prescriptions, and many diabetic patients in my network are unaware of it. Hence, I felt compelled to write this article to raise awareness among my readers. Please share this information with anyone facing metabolic challenges or type II diabetes. I am convinced that type II diabetes can be reversed with personal accountability and professional guidance.

However, reversing chronic conditions like diabetes is challenging. The complex mechanisms involved require a multifaceted approach and a considerable commitment from patients, healthcare professionals, and caregivers. Healing cells, tissues, organs, and systems demands time and effort.

The sooner we identify issues, the more effectively they can be addressed. The CDC states that "90% of 88 million Americans may be unaware they have prediabetes." Therefore, prioritizing blood sugar management is essential, along with raising awareness among friends, family, colleagues, and community members.

What is CGM, and why is it essential?

According to an NIH publication, CGM is gaining traction as more evidence supports its use.

The data provided by CGM allows for significantly more precise adjustments in insulin dosing and other therapies compared to traditional self-monitoring of blood glucose (SMBG).

I would like to summarize key points from the literature, my research, and personal experiences with these technologies. Using CGM devices has enabled me and my loved ones to identify an optimal diet through experimentation.

For instance, I discovered that I am carb-intolerant, as even a small amount of carbohydrates rapidly elevates my blood sugar. In contrast, my wife can consume three times as many carbs with minimal effects on her glucose levels.

CGM technologies facilitate the automatic collection of data, generating interest in non-invasive glucose monitoring as an additional method for understanding glucose levels.

Continuous Glucose Monitoring (CGM) is a device designed to consistently track glucose (sugar) levels. It comprises three components: a display monitor (often a smartphone), a sensor placed under the skin, and a transmitter that relays data to the monitor.

Historically, these devices were used in conjunction with traditional fingerstick glucose monitoring. However, in July 2016, the FDA approved the Dexcom G5 CGM for independent use.

Newer models do not require calibration with fingerstick tests. CGM provides both past and real-time glucose data, helping users identify low or high sugar levels, predict potential dips, and observe fluctuations in glucose.

Popular CGM brands such as Dexcom G6 and Medtronic Guardian Connect are widely utilized. Research has shown that users of these devices experience increased time spent within the target glucose range and fewer episodes of hypoglycemia.

CGM proves to be an invaluable resource for patients and healthcare providers, assisting in medication adjustments and lifestyle changes for improved glucose control. Ongoing advancements aim to integrate CGM with automated insulin delivery systems for artificial pancreas technology.

There are two types of CGM: professional (used in clinical settings for data analysis) and personal (owned by patients for real-time glucose monitoring).

These technologies lead to enhanced quality of life and reduced risk of immediate complications. For instance, CGM users report better glycemic control and reduced anxiety related to hypoglycemia.

Thus, utilizing CGM devices boosts patient confidence in managing diabetes and serves as a preventative measure for healthy individuals.
