Monitoring your blood sugar levels regularly is an important way for diabetics to manage their health. This article explains key blood glucose terms and healthy ranges to provide context for at-home testing.

What is Blood Sugar?

Blood sugar, or blood glucose, refers to the amount of sugar circulating in your bloodstream. It comes from consuming carbohydrate foods and is the primary energy source for your body's cells.

Insulin, a hormone made in the pancreas, controls blood sugar movement into cells. Managing carbohydrate intake and insulin therapy keeps levels balanced.

Why Tracking Blood Sugar Matters

Checking blood sugar readings periodically:

  • Detects dangerously high or low levels
  • Monitors impacts of diet, exercise and medication
  • Identifies patterns needing lifestyle adjustment
  • Improves daily blood sugar stability
  • Lowers risks of diabetic complications

Consistent testing paired with responsively adjusting insulin or food enables better health.

Target Blood Sugar Ranges


Before Meals

After Meals

For diabetics

70-130 mg/dL

<180 mg/dL

For non-diabetics

70-100 mg/dL

<140 mg/dL

Aim to keep your personal readings in the healthy target range based on medical guidance.

Interpreting Blood Sugar Test Results

Use this context to understand results:

  • Hypoglycemia - Below 70 mg/dL - Immediate carbohydrate intake needed
  • Normal - 70-130 mg/dL fasting - Ideal for diabetes management
  • Hyperglycemia - Above 130-140 mg/dL - Signals insulin adjustment required

Consult your doctor to establish personalized healthy target zones.

Tips for Managing Blood Sugar

Here are some proactive tips to help stabilize blood sugar:

  • Exercise regularly - Activity helps lower glucose levels by making cells more sensitive to insulin. Aim for 30+ minutes daily.
  • Limit refined carbs/sugars - These spike blood sugar rapidly. Focus on high-fiber whole grains, vegetables, and lean protein instead.
  • Stay hydrated - Drink water instead of sweetened beverages. Dehydration causes hyperglycemia.
  • Take medication as prescribed - Missing insulin doses let blood sugar get too high. Set reminders if needed.
  • Reduce stress - High stress increases blood sugar. Practice relaxation habits.
  • Check often - Don't just test when feeling symptoms. Routine checking ensures you catch highs/lows early before problematic.

Following healthy lifestyle habits prevents the blood sugar rollercoaster!

Warning Signs of Highs and Lows

Recognizing symptoms like the following ensures you can take quick corrective action when experiencing hyper/hypoglycemia:

High blood sugar symptoms:

  • Extreme thirst
  • Frequent urination
  • Vision changes
  • Slow healing cuts

Low blood sugar symptoms:

  • Hunger, nausea
  • Sweating, chills
  • Dizziness, tremors
  • Confusion, unconsciousness

Catching fluctuations early avoids hospitalization risk!

Frequently Asked Questions (FAQs)

Q1: What is blood sugar?

Blood sugar refers to the concentration of glucose present in the bloodstream. It is also known as blood glucose.

Q2: How is blood sugar measured?

Blood sugar is measured by using a glucose meter to obtain a small drop of blood, typically from a finger prick. The measurement is expressed in milligrams per deciliter (mg/d) or millimoles per liter (mmol/L of blood.

Q3: Why is blood sugar control important?

Blood sugar control is important because it plays a crucial role in overall health, especially for individuals with diabetes.


Monitoring your blood sugar readings and understanding what levels signal hypoglycemia vs hyperglycemia allows you to proactively manage diabetes symptoms. Use a blood sugar log to track trends over time informed by your personalized healthy ranges. 

Employ lifestyle adjustment tips like more activity, carb moderation, medication compliance, and stress reduction to stabilize glucose levels.
