What is the Meaning of Blood Sugar Level?

When we talk about optimal health, one key factor often discussed is blood sugar levels. Blood sugar, or glucose, is the main type of sugar found in your blood and comes from the food you eat. It’s your body’s primary source of energy, fueling your brain, muscles, and all your cells.

But what exactly do blood sugar levels mean for your health? Essentially, they measure how much glucose is circulating in your blood at any given time. Keeping these levels within a healthy range is crucial because it helps maintain energy balance and prevents health issues. If blood sugar levels are too high or too low, it can lead to immediate and long-term health complications.

For optimal health, it's important to understand how your body processes glucose and the role of insulin, a hormone that helps regulate blood sugar. When your body functions properly, insulin ensures that glucose is efficiently used or stored, keeping your blood sugar levels steady. This balance is vital for maintaining energy, preventing chronic diseases like diabetes, and ensuring overall well-being. By paying attention to your blood sugar levels and understanding how to manage them, you can take significant steps toward achieving and maintaining optimal health.

Insulin and Blood Sugar Levels

When you eat, your body breaks down carbohydrates from foods like bread, rice, fruits, and sweets into glucose. This glucose then enters your bloodstream. Whenever our glucose levels rise, a hormone called insulin is released by our pancreas. Insulin signals the cells to uptake and store glucose from the blood.

When our cells can efficiently uptake and store glucose, it's called good insulin sensitivity. If this process fails, glucose remains in the blood, leading to insulin resistance because insulin cannot transport glucose into the cells.

Your pancreas releases a hormone called insulin, which helps move glucose from your blood into your cells, where it's used for energy. If you have more glucose than your body needs at the moment, insulin helps store the excess in your liver to use later.

Insulin is thus the "main regulator" of our carbohydrate metabolism. Together with another hormone called glucagon and a series of other hormones, it regulates the blood sugar level in the body. If the blood shows an excess of blood sugar, it's termed hyperglycemia. If there's too little blood sugar, it's termed hypoglycemia.

The more sensitive you are to insulin, the less resistant you are, and vice versa.

From a health perspective, insulin isn't inherently "good" or "bad." It depends on how well the body can process it. Insulin plays crucial roles in the body, and its activation can be either beneficial or harmful for certain groups of people.

Individuals who are overweight, have a sedentary lifestyle and are relatively inactive

should minimize insulin secretion. Conversely, very active individuals as well as endurance or strength athletes should apply strategies for optimal carbohydrate intake to maximize performance through the effect of insulin.

For most people, normal blood sugar levels when fasting (not eating for 8 hours) range between 70-100 mg/dL. After eating, it's typically less than 140 mg/dL.

Blood Sugar and Type 2 Diabetes

Every time we eat, our bodies release insulin, especially when we consume carbohydrates. However, not all carbs are created equal. "Short-chain" carbohydrates, often low in fiber, cause a more significant spike in insulin levels. These include for example:

Table/cane sugar,
Beet sugar
Sweets with added sugar
Many baked goods
Cereals
Fruit juices
Highly processed foods

Some fruits and dairy products also contain short-chain carbohydrates. On the other hand, "long-chain" carbohydrates, found in starchy vegetables, whole grains, potatoes, oats, nuts, and legumes, cause a slower and less intense rise in blood sugar levels.

Protein-rich or fatty foods cause minimal or no increase in insulin. When insulin sensitivity is low, the body doesn't absorb enough glucose, leading to insulin resistance. This can develop into type 2 diabetes and other related conditions.

Symptoms of Blood Sugar Problems

Symptoms of abnormal blood sugar levels can vary widely. Generally, symptoms appear when blood sugar levels fall below 70 mg/dL (3.9 mmol/L) or rise above 180 mg/dL (10 mmol/L).

Measuring Blood Sugar Levels

Blood sugar levels can be measured in several ways, including:

Plasma Glucose Random Test: A blood test taken at any time.
Fasting Plasma Glucose Test: A blood test taken after fasting.
Oral Glucose Tolerance Test: A blood test after drinking a sugary solution.

Modern technology like Continuous Glucose Monitoring (CGM) uses a small device inserted under the skin to measure blood sugar in the interstitial fluid. It can be connected to a smartphone and notify the user if their blood sugar is too high or too low.

Symptoms of High Blood Sugar Levels

Symptoms of high blood sugar levels include:

Blurred vision
Dry mouth and skin
Fatigue
Fruity breath odor
Increased thirst
Nausea
Rapid heartbeat
Shortness of breath
Stomach pain

Symptoms of Low Blood Sugar Levels

Symptoms of low blood sugar levels include:

Anxiety
Headaches
Dizziness
Fatigue
Trembling
Rapid heartbeat
Nausea
Cramps
Weakness
Excessive sweating
Confusion
Drowsiness

Some people may not experience noticeable symptoms even when their blood sugar levels are abnormal.

How To Regulate and MaintainHealthy Blood Sugar Levels through a Healthy Lifestyle

Avoid Sugar from Fruit Juices, Sweets, and Processed Foods:
- Fruit Juices: While fruit juices may seem healthy, they often contain high levels of fructose and lack the fiber found in whole fruits, leading to rapid spikes in blood sugar. Opt for whole fruits instead.
- Sweets: Foods like candies, cookies, cakes, and pastries are loaded with added sugars and offer little nutritional value. They cause quick spikes in blood sugar followed by rapid drops, leading to energy crashes and increased hunger.
- Processed Foods: Many processed foods contain hidden sugars, unhealthy fats, and refined carbohydrates. Reading labels carefully and choosing whole, unprocessed foods can help maintain stable blood sugar levels.
Lower-Carbohydrate Diet:
- Reducing carbohydrate intake can help manage blood sugar levels by decreasing the demand for insulin. Focus on high-quality, nutrient-dense carbohydrates such as non-starchy vegetables, berries, and legumes.
- Incorporate healthy fats (like avocados, olive oil, and nuts) and lean proteins (such as fish, poultry, and tofu) to provide sustained energy and reduce blood sugar fluctuations.
Meal Frequency:
- Eating Less Frequently: Consuming fewer meals per day (2-3 larger meals instead of multiple small ones) can help reduce the burden on the pancreas by allowing longer periods without insulin production.
- Intermittent Fasting: This approach involves alternating periods of eating and fasting. Common methods include the 16/8 method (16 hours of fasting and an 8-hour eating window) or the 5:2 method (eating normally for 5 days and reducing calorie intake for 2 non-consecutive days). Intermittent fasting can improve insulin sensitivity and help stabilize blood sugar levels.
Balanced Meals:
- Ensure each meal includes a balance of macronutrients: complex carbohydrates, lean proteins, and healthy fats. This combination slows down the digestion and absorption of glucose, leading to more stable blood sugar levels.
- Incorporate fiber-rich foods, such as vegetables, whole grains, legumes, and fruits. Fiber slows the absorption of sugar and improves blood sugar control.
Hydration:
- Staying well-hydrated is essential for maintaining optimal blood sugar levels. Water helps the kidneys flush out excess glucose through urine. Aim for at least 8 glasses of water a day.
Regular Physical Activity:
- Engage in regular exercise, such as walking, swimming, cycling, or strength training. Physical activity helps muscles use glucose for energy, reducing blood sugar levels and improving insulin sensitivity.
Stress Management:
- Chronic stress can lead to elevated blood sugar levels due to the release of stress hormones like cortisol. Practices such as yoga, meditation, deep breathing exercises, and mindfulness can help manage stress and improve blood sugar control.
Sleep Quality:
- Poor sleep can negatively impact blood sugar levels and insulin sensitivity. Aim for 7-9 hours of quality sleep per night and establish a consistent sleep routine.
Monitoring Blood Sugar Levels:
- Regularly checking blood sugar levels can help you understand how different foods and activities affect your blood sugar. Keeping a log of your readings, meals, and activities can help identify patterns and make informed adjustments.

By incorporating these strategies into your lifestyle, you can better manage blood sugar levels, reduce the risk of type 2 diabetes, and improve overall health.
