Maintaining a stable blood sugar range is crucial for overall health, particularly for individuals living with diabetes. However, many people are unaware of the consequences of poor blood sugar control on their bodies. Fluctuations in blood sugar levels can have far-reaching effects, impacting not only physical health but also mental well-being.
The Risks of Blood Sugar Spikes and Drops
When we eat or drink something high in carbohydrates, our body releases insulin to regulate blood glucose levels. However, if the pancreas is unable to produce enough insulin or if the cells become resistant to it, blood sugar levels can skyrocket. This can lead to a range of problems, including fatigue, dizziness, and blurred vision (1). Conversely, when blood sugar drops too low, symptoms such as shakiness, confusion, and irritability can occur.
Understanding Insulin Sensitivity
Insulin sensitivity is the body's ability to effectively use insulin. When we are insulin sensitive, our cells respond promptly to glucose levels in the bloodstream. However, when cells become resistant, it leads to increased blood sugar levels (7). This resistance is often a precursor to type 2 diabetes and can be exacerbated by factors such as obesity, physical inactivity, and an unhealthy diet.
The Role of Fiber in Regulating Blood Sugar
Diet plays a significant role in maintaining healthy blood sugar levels. A high-fiber diet has been shown to have a positive impact on insulin sensitivity (10). Foods rich in fiber like fruits, vegetables, whole grains, and legumes slow down carbohydrate digestion, which helps regulate glucose release into the bloodstream.
The Link Between Sleep Quality and Blood Sugar
Poor sleep quality can disrupt blood sugar regulation. During deep sleep stages 3-4 of non-rapid eye movement (NREM) sleep and rapid-eye-movement (REM) stage, our body releases hormones that help lower insulin levels in the morning. Conversely, during light NREM sleep stages 1-2 and REM stage at night when we are not producing as much cortisol which can cause an increase in glucagon which triggers a spike of glucose production from the liver (8). Additionally, research suggests that people with type 2 diabetes often experience poor-quality sleep.
The Importance of Tracking Blood Sugar Levels
Regularly monitoring blood sugar levels helps individuals living with diabetes understand their condition and take necessary steps to manage it. Using glucometers or continuous glucose monitors (CGMs) can provide accurate readings, helping patients identify patterns in their blood sugar fluctuations (16). This awareness is crucial for fine-tuning treatment plans and adjusting medications if needed.
The Connection Between Blood Sugar Levels and Weight Management
Research has consistently shown that managing blood sugar levels leads to better weight management outcomes. When glucose enters the bloodstream at an unhealthy rate, insulin resistance increases, promoting fat storage over energy expenditure (16). Conversely, maintaining stable blood sugar levels can help regulate body mass index (BMI) and body composition.
Reducing Diabetes Risk by Maintaining a Healthy Blood Sugar Range
While diabetes risk factors are largely out of our control, maintaining healthy lifestyle habits reduces the likelihood of developing this condition. Individuals with high fasting glucose values above 100 mg/dl may have an increased risk of type-2-diabetes whereas those below normal range (less than 60 mg/dL) might reduce their chance to develop diabetes significantly by having healthier blood sugar level which can be further achieved through regular exercise combined with balanced diet and stress-reduction practices.
Maintaining a healthy balance between physical activity, nutritional intake, sleep quality, and stress management is crucial for managing stable blood glucose levels.
