Why Monitoring Blood Sugar is Important
Blood glucose, or blood sugar, is the main sugar found in your blood, and it comes from the food you eat. Your body uses glucose for energy. Keeping blood sugar levels within a healthy range is vital because consistently high or low levels can lead to serious health problems.
- High blood sugar (hyperglycemia) can damage blood vessels and organs over time, leading to complications like heart disease, kidney disease, nerve damage (neuropathy), and vision problems.
- Low blood sugar (hypoglycemia) can cause symptoms like shakiness, sweating, dizziness, and, in severe cases, seizures or loss of consciousness.

Several factors can influence blood sugar levels, including:
- Diet: The type and amount of carbohydrates you consume significantly impact blood sugar. Simple carbs can cause rapid spikes, while complex carbs are digested more slowly.
- Physical Activity: Exercise can lower blood sugar levels as muscles use glucose for energy.
- Medications: Certain medications, such as insulin, oral diabetes drugs, steroids, and some antidepressants, can affect blood sugar.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and illnesses can cause fluctuations in blood sugar.
- Time of Day: Blood sugar levels can vary throughout the day, typically being lowest in the morning before eating.
- Age: Normal blood sugar ranges might be slightly different based on the age
Normal Blood Sugar Levels Chart for Adults
This chart provides a general guideline for normal blood sugar ranges for adults, both with and without diabetes. Remember that individual targets may vary based on your health status and your healthcare provider's recommendations.
| Measurement | Normal (No Diabetes) | Target Range (Diabetes) |

| Fasting Blood Sugar (after at least 8 hours of fasting) | 70-99 mg/dL | 80-130 mg/dL |
| 2-Hour Postprandial (2 hours after starting a meal) | Less than 140 mg/dL | Less than 180 mg/dL |
| HbA1c (Average blood sugar over 2-3 months) | Less than 5.7% | Less than 7% (often recommended) |
- mg/dL stands for milligrams per deciliter, the standard unit of measurement for blood sugar in the United States.
- HbA1c provides an average of your blood sugar control over a longer period and is often used to monitor diabetes management.
