Glucose

Overview

Glucose, also known as blood sugar, is the primary source of energy for the body. It is derived from the food we eat, particularly carbohydrates, and is essential for cellular function and energy production^[1]. The regulation of glucose levels is crucial for maintaining optimal health, as both high and low levels can lead to serious health issues. Tracking glucose levels is important for diagnosing and managing conditions like diabetes and prediabetes^[2].

Scientific Background

Glucose metabolism involves its breakdown and utilization by cells for energy. The pancreas plays a key role in regulating glucose levels through the hormones insulin and glucagon. Insulin lowers blood glucose by facilitating its uptake into cells, while glucagon raises blood glucose by stimulating glycogen breakdown in the liver^[1]. Glucose is also stored as glycogen in the liver and muscles for later use^[3].

Measurement and Testing

Glucose levels are commonly measured using blood glucose tests, which can be performed at home with a glucometer or in a clinical setting. Factors affecting test results include diet, physical activity, and certain medications^[4]. Regular testing is recommended for individuals with diabetes or those at risk of developing it.

Reference Ranges

Normal fasting glucose levels typically range from 60 to 100 mg/dL, while postprandial levels should be below 140 mg/dL^[1]. For individuals with diabetes, target ranges may vary based on age and health status^[2]. Demographic variations, such as age and pregnancy status, can influence these ranges.

High Values

Elevated glucose levels, known as hyperglycemia, can result from diabetes, insulin resistance, or certain medications^[4]. High glucose levels increase the risk of complications like heart disease and nerve damage^[2]. Symptoms may include increased thirst and urination.

Low Values

Low glucose levels, or hypoglycemia, often occur due to excessive insulin use or certain medications^[4]. Hypoglycemia can lead to confusion, seizures, and even brain damage if untreated^[4]. Symptoms include shakiness and dizziness.

Improving Biomarker Levels

Lifestyle modifications such as a balanced diet, regular exercise, and weight management can help regulate glucose levels^[1]. Interventions may include medication for diabetes management. While supplements like chromium and berberine may have some benefits, they should be used under medical supervision.

Importance of Tracking

Monitoring glucose levels is crucial for managing diabetes and preventing complications. It helps in making informed decisions about diet, exercise, and medication^[2]. Regular tracking can also identify early signs of prediabetes or diabetes, allowing for timely intervention.
