What is normal blood sugar level for average man or woman?
What are possible reasons of increase in blood sugar levels?
High blood sugar (hyperglycemia) can occur due to various factors, including poor diet—such as excessive sugary foods, refined carbs (white bread, pasta), and processed snacks—which cause rapid glucose spikes. A sedentary lifestyle reduces insulin sensitivity, leading to glucose buildup, while insulin resistance (common in prediabetes and Type 2 diabetes) prevents cells from properly absorbing sugar. Chronic stress triggers the release of cortisol and adrenaline, flooding the bloodstream with glucose, and inadequate sleep disrupts insulin regulation, further elevating blood sugar. Certain medications (steroids, diuretics, antidepressants), illness or infection (which activate stress hormones), and dehydration (concentrating glucose in the blood) can also contribute. Hormonal imbalances like PCOS or Cushing’s syndrome impair insulin function, and diabetics may experience dangerous spikes if they skip or incorrectly dose insulin or oral medications. Managing these factors through diet, exercise, stress reduction, and proper medical care is key to maintaining healthy blood sugar levels.
How to measure blood sugar level?
To measure blood sugar levels, the most common method is using a fingerstick glucose meter: wash hands, insert a test strip, prick your fingertip with a lancet, and apply the blood drop to the strip for instant results (typically in 5-10 seconds). For continuous monitoring, a CGM (Continuous Glucose Monitor) tracks levels in real-time via a small sensor under the skin. Lab tests like the HbA1c (averages 2-3 months of glucose levels) and the Oral Glucose Tolerance Test (OGTT, used for diabetes diagnosis) provide broader insights. Testing times vary—fasting (70-99 mg/dL is normal), post-meal (<140 mg/dL after 2 hours), or before bed help track fluctuations. For accuracy, avoid squeezing the finger, rotate testing sites, and periodically calibrate your meter. Whether you use a traditional glucometer or advanced CGM, regular monitoring is key to managing diabetes and maintaining healthy blood sugar levels.
What to eat if your blood sugar level is higher than optimized blood sugar level?
If your blood sugar level is higher than the optimized range, it's important to focus on low-glycemic, nutrient-dense foods that help stabilize glucose levels. Opt for non-starchy vegetables like spinach, broccoli, and cauliflower, lean proteins such as grilled chicken or tofu, and whole grains in moderation, like quinoa or oats. Healthy fats from avocados, nuts, and seeds can also slow sugar absorption. Avoid sugary drinks, white bread, refined carbs, and processed snacks. Instead, eat balanced meals with fiber, protein, and healthy fats to prevent spikes and support insulin sensitivity.
What to avoid if your blood sugar level is higher than optimized blood sugar level?
If your blood sugar level is higher than the optimized range, you should avoid foods and drinks that cause rapid spikes in glucose levels. Steer clear of sugary beverages like soda, energy drinks, and sweetened fruit juices, as well as processed foods high in refined carbs such as white bread, pastries, and chips. Limit your intake of sweets, candies, and desserts that are rich in added sugars. Avoid high-glycemic fruits like bananas and grapes in large quantities, and reduce consumption of saturated and trans fats found in fried and fast foods. Minimizing these items can help bring your blood sugar back under control.
What to do if your blood sugar level is down?
If your blood sugar level drops too low (a condition known as hypoglycemia), it's important to act quickly to raise it to a safe range. Immediately consume fast-acting carbohydrates such as glucose tablets, fruit juice, regular (non-diet) soda, or a tablespoon of honey or sugar. Wait 15 minutes, then recheck your blood sugar level—if it’s still low, repeat the process. Once stabilized, eat a balanced snack or meal containing protein and complex carbohydrates to prevent another drop. If symptoms like shakiness, dizziness, sweating, or confusion persist, seek medical help immediately.
Conclusion
Maintaining a healthy blood sugar level is essential for overall well-being, whether you're managing diabetes or aiming to prevent it. Understanding the normal range, recognizing the causes of high or low levels, and making informed dietary and lifestyle choices can significantly improve your glucose control. Regular monitoring using a glucometer or CGM, combined with a balanced diet, physical activity, stress management, and proper medical care, helps keep blood sugar levels within the optimized range. By staying informed and proactive, you can reduce the risk of complications and lead a healthier, more balanced life.
