Decoding Blood Sugar: Your Body’s Fuel Gauge

Understanding blood sugar is akin to understanding your car’s fuel gauge. It provides essential information about your body’s energy source – glucose. This guide will walk you through the intricacies of blood sugar, from testing methods to the significance of those numbers in your daily life.

Measuring Blood Sugar: A Look Under the Hood

Just as a mechanic checks your car’s fluids, blood sugar tests provide a snapshot of your glucose levels:

Blood Glucose Meters: These convenient at-home devices require a small finger prick to obtain a blood sample. A test strip analyzes the blood and displays the glucose level on the meter.
Continuous Glucose Monitors (CGMs): Offering a more dynamic view, CGMs use a small sensor inserted under the skin to continuously track glucose levels. Data is transmitted to a receiver, such as a smartphone app, providing real-time insights. Hello Lingo and Lilly Tempo are examples of companies offering CGM technology.

Interpreting the Numbers: What’s Normal?

Blood sugar levels naturally fluctuate throughout the day, influenced by factors like age, overall health, time of day, and what you eat. The World Health Organization (WHO) suggests a fasting blood sugar range of 70-100 mg/dL for adults under 60 and 70-110 mg/dL for those 60 and older. Healthline and Forbes offer further information on normal blood sugar ranges. However, consulting your doctor is crucial to determine your personalized target range.

High Blood Sugar (Hyperglycemia): When Things Get Too Sweet

Hyperglycemia occurs when blood sugar levels remain elevated for extended periods. This can damage organs and tissues over time. WebMD provides more details on the causes, symptoms, and risks of high blood sugar.

Recognizing the Signs: Symptoms of High Blood Sugar

Several symptoms may suggest elevated blood sugar:

Frequent Urination: Excess glucose is flushed out through the urine, leading to increased bathroom trips.
Excessive Thirst: Frequent urination can cause dehydration, triggering increased thirst.
Fatigue: Cells unable to access glucose for energy may lead to feelings of tiredness.
Blurred Vision: High blood sugar can impact eyesight.
Headaches: Elevated glucose levels can contribute to headaches.

Continuous Glucose Monitoring (CGM): A Deeper Dive

CGMs offer a continuous stream of data, allowing you to see how your blood sugar responds to food, activity, and stress. This information empowers you to make informed decisions about your diabetes management in collaboration with your healthcare provider. Studies suggest that CGMs can improve A1C levels, a measure of long-term blood sugar control.

Beyond Normal: Personalizing Your Approach

There’s no one-size-fits-all approach to blood sugar management. Factors such as genetics, activity levels, and food preferences create individual variations. Working with your healthcare team to develop a personalized plan is crucial for optimal results.

What is Blood Sugar All About?

Your body relies on glucose, a type of sugar, as its primary fuel source. This energy powers essential functions, from breathing to physical activity. Carbohydrates from food are broken down into glucose, which enters the bloodstream. Insulin, a hormone produced by the pancreas, acts as a key, allowing glucose to enter cells and provide energy.

When insulin production is insufficient or cells become resistant to insulin, glucose builds up in the bloodstream, leading to high blood sugar (hyperglycemia). Over time, this can damage blood vessels and nerves, increasing the risk of complications such as heart disease, kidney disease, and nerve damage. Maintaining balanced blood sugar levels requires careful management, often involving regular exercise, a balanced diet, and sometimes medication. Ongoing research continues to explore the complexities of blood sugar regulation.

Is 135 Blood Sugar High in the Morning?

A fasting blood sugar of 135 mg/dL is generally considered elevated and may indicate prediabetes. This suggests your body isn’t processing sugar as effectively as it should. Several factors can contribute to high morning blood sugar:

Dawn Phenomenon: A normal hormonal shift in the early morning hours can cause the liver to release stored glucose.
Somogyi Effect: A rebound effect from low blood sugar during the night can lead to elevated morning levels.
Lifestyle Factors: Late-night snacks, high-carbohydrate dinners, and lack of physical activity can influence morning blood sugar levels.

Consistently elevated blood sugar, even within the prediabetes range, increases the risk of developing type 2 diabetes and other health complications. Consulting your doctor is essential for appropriate testing and personalized management strategies, which may include lifestyle changes and medication.
