A continuous glucose monitor (CGM) may not tell the full truth.

A patient asked a common question highlighting the confusion many face when comparing their CGM’s estimated A1c (GMI) with the result from a blood test. He mentioned that their CGM estimated their A1c at 7.2, but their actual A1c from blood work came back at 8.3—a significant difference. So, what went wrong?

The Key Difference: CGM vs Blood A1c

The first thing to understand is that the estimated A1c, known as GMI (Glucose Management Indicator), from a CGM, is different from the blood test A1c that a doctor orders. The GMI estimates what the A1c could be based on the blood sugars that the CGM picks up. However, it’s important to note that the CGM measures glucose in interstitial fluid, not directly from blood. This is a key difference because interstitial fluid can sometimes provide readings that are slightly higher or lower than actual blood sugar levels.

Why the Difference?

Because the CGM measures glucose in interst...

When it comes to managing blood sugar levels, individuals with diabetes are often on the lookout for new remedies.

One fruit that has gained attention is bitter melon, a tropical fruit found in regions like Asia and Central America. This fruit has been used for centuries in traditional medicine to treat various conditions, from rheumatoid arthritis to psoriasis. Recently, it has been suggested that bitter melon might help manage blood sugar for those with Type 1 or Type 2 diabetes. But what does the science say about this claim? Let’s take a closer look.

What is Bitter Melon?

Bitter melon is known for its distinct, bitter taste and unique properties. It is believed to have antibacterial, antiviral, anti-inflammatory, and pain-relieving benefits. Some people think it may help lower blood sugar levels by improving how the body uses glucose—acting like insulin. But does research support these claims?

Research on Bitter Melon for Type 2 Diabetes

Several studies have been conducted to ...

Hiking while managing diabetes can seem daunting, but with the right planning and preparation, it becomes much easier.

A registered dietitian and certified diabetes educator can help guide individuals with Type 1 or Type 2 diabetes to achieve balance during physical activities like hiking. Explore the steps the T1D dietitian took to hike while keeping blood sugars in check.

1. Start with a Balanced Breakfast

According to Ben, ensuring the right breakfast is the first step in preparing for a hike. A good combination of protein and carbohydrates is essential for quick energy while sustaining blood sugars throughout the hike. This balance helps keep the body fueled while preventing spikes or crashes in glucose levels during physical activity.

2. Monitor Insulin Levels

Before embarking on the hike, the diabetes educator ensures that insulin on board is kept on the lower side. This step is crucial in preventing hypoglycemia (low blood sugar) during the hike. Proper insulin management i...

Living with diabetes, whether it’s Type 1 (T1D) or Type 2 (T2D), means paying close attention to how and where you manage your insulin.

For people with Type 1 diabetes or Type 2 diabetes, using insulin pumps, continuous glucose monitors (CGMs), or injecting insulin is a part of daily life. However, one essential tip that many diabetes dietitians recommend is rotating your insulin sites. Here’s why it’s important and where you can place your devices for optimal results.

Why Rotate Your Insulin Pump Sites?

One of the key pieces of advice from a T1D dietitian or T2D dietitian is to avoid injecting or placing your insulin pump in the same spot repeatedly. Doing so can lead to the development of scar tissue, which can impact insulin absorption. Over time, scar tissue can make it harder for insulin to be absorbed properly, leading to fluctuating blood sugar levels and less effective treatment.

Rotating your insulin sites allows the tissue to heal, ensuring better absorption of insulin an...

Managing blood sugar levels can feel overwhelming, especially for those navigating the world of diabetes.

Whether it’s Type 1 diabetes (T1D) or Type 2 diabetes (T2D), understanding how to balance meals can lead to more stable blood sugar readings. Here are three effective strategies to implement at mealtimes, recommended by a diabetes dietitian, to help keep blood sugars in check.

 1. Count Carbs

Carbohydrate counting is essential for anyone managing diabetes. It involves assessing portion sizes and understanding how many carbs are on the plate. This skill serves as the foundation for maintaining healthy blood sugar levels. For those unsure how to count carbs effectively, reaching out to a diabetes dietitian can make a significant difference. A Type 1 or Type 2 diabetes dietitian can provide personalized guidance tailored to individual needs, making it easier to enjoy meals without the stress of unexpected blood sugar spikes.

2. Timing Your Insulin Dose

Insulin timing is crucial. ...

Planning a vacation is always exciting, but if you are living with diabetes, preparations require a little extra thought.

Whether it’s a family road trip or a beach getaway, understanding how to manage blood sugar levels while traveling is crucial. 

Understanding the Impact of Travel on Blood Sugar

Travel often means long hours of sitting, which can increase insulin resistance. This means blood sugar levels can rise, even if the usual routine is disrupted. For individuals with Type 1 diabetes, staying on top of insulin doses is essential. A T1D dietitian can provide personalized advice for adjusting insulin rates during travel. Similarly, those managing Type 2 diabetes can benefit from insights offered by a dietitian.

Adjusting Basal Rates for Long Journeys

One effective strategy for maintaining stable blood sugar during travel is to consider increasing the basal insulin rate for the day of the trip. While this may sound intimidating, it’s a smart move. When sitting for extended p...

If you're living with diabetes, whether it's Type 1 (T1D) or Type 2 (T2D), you know that managing blood sugar levels is key to staying healthy.

One often overlooked area of diabetes management is how exercise affects blood sugar levels, and unfortunately, your diabetes care team may not always give you the best advice. As a result, your workouts may feel harder, and you may struggle with blood sugar fluctuations. Fortunately, as a diabetes dietitian, I’m here to help you navigate exercise and nutrition for better blood sugar control and improved fitness outcomes.

Why Your Care Team Might Not Have the Best Advice

Your Type 1 diabetes dietitian or T2D dietitian might suggest a one-size-fits-all approach to exercise, treating cardio and strength training the same. However, different types of physical activity affect your blood sugar in unique ways. For example, cardio exercise like jogging or hiking often lowers blood sugar, while intense activities like weightlifting or sprinting can ...

Living with diabetes can sometimes feel overwhelming, but small changes can make a big difference.

Whether you have Type 1 diabetes (T1D) or Type 2 diabetes (T2D), working with a registered dietitian and certified diabetes educator can help you find the best strategies for your lifestyle. Here are four essential tips to improve your insulin sensitivity and help keep your blood sugar levels in check.

1. Move Your Body Regularly

Staying active is crucial for everyone, especially for those with diabetes. Exercise helps your body use insulin more effectively, making it easier to control blood sugar levels. When you move, your cells become better at taking up glucose, which can lead to more stable blood sugar readings. Whether walking, dancing, or playing sports, find an activity you enjoy and stick with it. A T1D dietitian or T2D dietitian can suggest tailored exercise plans to fit your needs.

2. Prioritize Quality Sleep

Did you know that sleep affects your blood sugar? When you don’t...

Managing diabetes is not just about monitoring blood sugar levels; it's about making informed food choices and understanding how they affect glucose levels.

Whether managing Type 1 diabetes (T1D) or Type 2 diabetes (T2D), the expertise of a diabetes dietitian is essential in creating a balanced meal plan that supports overall health. By working with a T1D or T2D dietitian, individuals can better understand how different foods impact blood sugar, allowing them to enjoy meals without compromising their health.
