Blood sugar, also termed blood glucose, is the concentration of glucose in the blood. It is the body’s main source of energy and is obtained from the food we eat, specifically from the carbohydrate content. Insulin, a substance produced by the pancreas, is responsible for the absorption of the sugar into the body’s cellular structures.

It is crucial to keep blood sugar levels within the normal range. If blood sugar levels are low or high, it could have a reaction on different parts of the body.

Why Maintaining Normal Blood Sugar Is Important

This will make sure that the brain and muscles receive adequate energy. Irregular levels can cause the following potential complications:

  • Diabetes and its complications
  • Fatigue and weakness
  • Frequent infections
  • Coronary heart disease and stroke
  • Kidney and nerve damage

Early awareness helps prevent long-term damage.

Explanation of Normal Blood Sugar Levels

**Normal blood sugar ranges explained
**Blood sugar levels are measured at different times and normal values vary based on timing and testing method.

  1. Fasting blood sugar

This test is done after at least 8 hours of fasting.

• Normal: 70-99 mg/dL
• Prediabetes: 100-125 mg/dL
• Diabetes: 126 mg/dL or higher

  1. Post-meal (postprandial) blood sugar

Measured about 2 hours after eating.

• Normal: Less than 140 mg/dL
• Prediabetes: 140-199 mg/dL
• Diabetes: 200 mg/dL or higher

  1. Random blood sugar

Measured at any time of the day.

• Normal: Usually below 140 mg/dL
• Diabetes suspected: 200 mg/dL or higher with symptoms

  1. HbA1c test (long-term sugar control)

HbA1c reflects average blood sugar over the past 2-3 months.

• Normal: Below 5.7%
• Prediabetes: 5.7-6.4%
• Diabetes: 6.5% or higher

HbA1c is a key test for diagnosing and monitoring diabetes.

Low Blood Sugar (Hypoglycemia)

It happens when blood sugar falls below the normal level. The symptoms include:

Factors Influencing Blood Sugar Levels

Blood sugar levels can be impacted by many conditions. These are:

These include:

  • Those with diabetes or prediabetes
  • Pregnant women with gestational diabetes
