A blood sugar level of 263 mg/dL is considered high and may be a cause for concern, especially if you have diabetes or are at risk of developing the condition. When your body's cells become less responsive to insulin, it can lead to elevated glucose levels in the bloodstream.
The Risks Associated with High Blood Sugar
High blood sugar levels like 263 mg/dL can increase your risk of complications such as heart disease, kidney damage, and nerve damage. Over time, consistently high blood sugar can cause inflammation and oxidative stress in the body, leading to a host of problems including blindness, amputations, and even death.
Maintaining a Healthy Blood Sugar Range
Fortunately, there are many ways to maintain a healthy blood sugar range and prevent complications from arising. This includes making lifestyle changes such as following a balanced diet that is low in processed foods and added sugars. You should also try to stay physically active by engaging in at least 150 minutes of moderate-intensity aerobic exercise per week.
The Importance of Monitoring Your Blood Sugar
Monitoring your blood sugar levels regularly can help you identify patterns and make adjustments as needed. This may involve using a glucometer, continuous glucose monitor (CGM), or working with a healthcare professional to develop an individualized plan for managing your condition.
Blood Sugar Fluctuations: What Causes Them?
There are several factors that can cause fluctuations in blood sugar levels such as stress, certain medications, and changes in sleep patterns. Stress is particularly problematic because it causes the release of cortisol and other hormones that raise blood glucose levels by triggering gluconeogenesis - a process where liver cells convert amino acids into glucose.
Lifestyle Adjustments for Lowering High Blood Sugar
In addition to monitoring your blood sugar regularly, making adjustments such as reducing stress through relaxation techniques like yoga or meditation can help. You should also try to improve sleep quality and get enough physical activity each day to reduce inflammation in the body.
