Your Blood Sugar Chart Explained: A Simple Guide to Your Target Range

Understanding your blood sugar chart is crucial for managing diabetes or simply keeping track of your overall health. Blood sugar levels, also known as glucose levels, fluctuate throughout the day, influenced by factors like meals, activity, and medication. This article provides a simple guide to interpreting your blood sugar levels and understanding your target range.

Why is Monitoring Blood Sugar Important?

Monitoring your blood sugar allows you and your healthcare provider to:

  • Understand how your body responds to different foods.
  • Recognize the impact of physical activity on your blood glucose.
  • Adjust your medication dosage effectively.
  • Prevent or delay long-term complications associated with diabetes.
  • Identify patterns and make informed lifestyle adjustments.

Ignoring consistently high or low blood sugar readings can lead to serious health complications, emphasizing the importance of regular monitoring and a clear understanding of your blood sugar levels. Understanding Low Blood Sugar Symptoms Hypoglycemia And How To Respond

Understanding the Basics: What Do Blood Sugar Numbers Mean?

Blood glucose is measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). In the United States, mg/dL is the standard unit. The chart below helps illustrate the normal ranges and what they signify:

Category Fasting Blood Sugar (mg/dL) 2 Hours After Meal (mg/dL)
Normal Less than 100 Less than 140
Prediabetes 100 to 125 140 to 199
Diabetes 126 or higher 200 or higher
  • Fasting Blood Sugar: This is the blood sugar level measured after at least eight hours of fasting (usually overnight). It provides a baseline reading.
  • Postprandial Blood Sugar (2 Hours After Meal): This measures blood glucose two hours after you start eating a meal. It indicates how well your body is processing the food you’ve consumed.

It's vital to note that these are general guidelines. Your individual target range may vary based on age, overall health, duration of diabetes, and the presence of other medical conditions. Always consult with your healthcare provider to establish a personalized blood sugar target.

Identifying High and Low Blood Sugar Levels

Knowing the signs and symptoms of high and low blood sugar is essential for quick intervention.

High Blood Sugar (Hyperglycemia)

Hyperglycemia occurs when your blood glucose level is too high. Symptoms include:

  • Increased thirst
  • Frequent urination
  • Blurred vision
  • Fatigue
  • Headaches

Untreated hyperglycemia can lead to serious complications such as diabetic ketoacidosis (DKA) or hyperglycemic hyperosmolar state (HHS), both requiring immediate medical attention.

Low Blood Sugar (Hypoglycemia)

Hypoglycemia occurs when your blood sugar level drops too low. Symptoms can include:

  • Shakiness
  • Sweating
  • Dizziness
  • Confusion
  • Irritability
  • Rapid heartbeat

Severe hypoglycemia can lead to seizures, loss of consciousness, and even death. It's important to treat hypoglycemia promptly by consuming fast-acting carbohydrates, such as glucose tablets or juice.
