Blood Tests & Monitoring
Blood glucose, also known as blood sugar, is a vital component of our body’s energy system. It’s essential to monitor and maintain healthy blood Glucose levels, especially for those with diabetes, as imbalances can lead to serious health complications.
Definition
Blood glucose is the sugar found in your blood. It comes primarily from the foods you eat, especially carbohydrates, and serves as the main energy source for your cells. The hormone Insulin helps regulate your blood Glucose levels by facilitating its transfer from the bloodstream into cells for energy use or storage.
Causes
Blood Glucose levels fluctuate based on various factors:
- Eating foods rich in carbohydrates, which increase blood glucose.
- Physical activity, which often lowers blood glucose as your body uses it for energy.
- Hormonal changes, stress, or illness, which can also impact glucose balance.
Risk Factors
Certain factors can increase the risk of abnormal blood Glucose levels:
- Lack of Insulin production or Insulin resistance (as in diabetes).
- A sedentary lifestyle.
- Obesity or being overweight.
- A diet high in sugar and processed carbohydrates.
- Family history of diabetes or metabolic disorders.
Symptoms
For high blood glucose (hyperglycemia):
- Increased thirst.
- Frequent urination.
- Fatigue.
- Blurred vision.
For low blood glucose (Hypoglycemia):
- Shakiness or dizziness.
- Sweating.
- Confusion.
- Weakness or fatigue.
Diagnosis
Blood Glucose levels can be measured through various tests:
- Fasting Blood Glucose Test: Measures Glucose levels after fasting for at least 8 hours.
- Random Blood Glucose Test: A snapshot of your Glucose levels at any time.
- HbA1c Test: Indicates average blood Glucose levels over the past 2–3 months.
- Oral Glucose Tolerance Test (OGTT): Monitors how your body processes glucose after consuming it.
Management
Managing blood glucose is crucial to prevent complications:
- Routine blood sugar monitoring using glucometers or continuous glucose monitors (CGMs).
- Healthy eating choices and balanced meals to control blood sugar spikes.
- Regular physical activity to keep Glucose levels stable.
- Prescribed medications or Insulin therapy for those diagnosed with diabetes.
- Regular check-ups to monitor long-term glucose control (like HbA1c levels).
FAQ
What is blood glucose?
Blood glucose, or blood sugar, is the amount of sugar present in your blood. It is a key energy source for your body, primarily derived from the food you eat.
What happens if blood Glucose levels are too high?
High blood glucose, or hyperglycemia, can lead to symptoms like thirst, Frequent urination, fatigue, and blurred vision. Over time, it may cause complications like nerve damage or heart disease.
How is blood glucose measured?
Blood glucose can be measured using a Glucometer, continuous glucose monitor (CGM), or through lab tests like Fasting glucose tests and HbA1c assessments.
What is the normal range for blood glucose?
For a non-diabetic, normal fasting blood glucose is typically between 70 and 100 mg/dL. After meals, levels should usually stay below 140 mg/dL.
