Blood sugar, also known as blood glucose, is a crucial element in the body’s energy system. It’s derived from the food we eat and serves as the primary fuel for our cells. Understanding blood sugar, its role in the body, and how to manage it is essential for maintaining good health and preventing conditions like diabetes.

What is Blood Sugar?
Blood sugar is the main sugar found in your blood. Your body breaks down most of the food you eat into glucose, releasing it into your bloodstream. This glucose is then used by your cells for energy, thanks to the hormone insulin, which is produced by the pancreas. Insulin helps move glucose from your blood into your cells.
The Role of Insulin
When your blood glucose levels rise after eating, the pancreas releases insulin. Insulin’s primary job is to help cells absorb glucose, lowering blood sugar levels in the process. However, in people with diabetes, this system doesn’t work properly. They either don’t produce enough insulin, can’t use insulin effectively, or both, leading to high blood sugar levels.
Types of Diabetes
Diabetes is a condition characterized by high blood glucose levels. There are two main types of diabetes:
- Type 1 Diabetes: This is an autoimmune condition where the body attacks insulin-producing cells in the pancreas. People with type 1 diabetes need to take insulin daily.
- Type 2 Diabetes: This is a more common form where the body either becomes resistant to insulin or doesn’t produce enough. It’s often linked to lifestyle factors and can sometimes be managed with diet and exercise alone, although medications or insulin may be needed.
Managing Blood Sugar Levels
For those with diabetes, keeping blood glucose within a target range is crucial. The typical targets are:
- Before meals: 80 to 130 mg/dL
- Two hours after meals: Less than 180 mg/dL
These targets can vary based on individual health conditions, so it’s important to consult with your healthcare team.
Monitoring Blood Sugar
Regular monitoring is key to managing diabetes. There are several ways to check blood glucose levels:
- Blood Glucose Meters: These devices measure glucose levels from a small drop of blood, usually taken from a fingertip.
- Continuous Glucose Monitoring (CGM): This involves a small sensor placed under the skin that measures glucose levels continuously throughout the day and night. It’s particularly useful for those who take insulin and experience frequent fluctuations in blood sugar.
The Importance of the A1C Test
The A1C test provides an average blood glucose level over the past three months and is a critical tool for managing diabetes. Most people with diabetes should have this test at least twice a year, or more frequently if their treatment goals aren’t being met.
Recognizing and Managing Hyperglycemia
Hyperglycemia, or high blood sugar, can cause symptoms like thirst, fatigue, headaches, frequent urination, and blurred vision. Persistent high blood glucose levels require adjustments in diet, activity levels, or medication. Additionally, incorporating blood sugar supplements can be beneficial in maintaining healthy levels.
Recognizing and Managing Hypoglycemia
Hypoglycemia, or low blood sugar, occurs when glucose levels drop below 70 mg/dL. Symptoms can include shaking, sweating, anxiety, irritability, dizziness, and hunger. It’s important to address low blood sugar quickly to prevent severe complications.
Blood Sugar and Overall Health
Maintaining healthy blood sugar levels is not only crucial for those with diabetes but also for overall health. High or low blood sugar can have serious consequences, affecting various organs and systems in the body. Proper management includes a balanced diet, regular physical activity, and routine medical check-ups. For those looking for additional support, there are various blood sugar supplements that can help manage levels effectively.
Frequently asked questions
The normal range for blood sugar levels varies depending on the time of day and whether you have eaten. For most people, the typical ranges are:
- Fasting (no food for at least 8 hours): 70 to 99 mg/dL
- Before meals: 80 to 130 mg/dL
- Two hours after meals: Less than 140 mg/dL
For individuals with diabetes, the target ranges may differ. It’s important to follow the guidelines provided by your healthcare team to maintain optimal blood glucose levels.
Managing blood sugar levels is crucial for overall health, especially for individuals with diabetes. Certain foods can cause significant spikes in blood glucose levels and should be consumed in moderation or avoided. Here are five of the worst foods for blood sugar:
Sugary Beverages: Drinks like soda, sweetened iced tea, and energy drinks are high in sugar and can cause rapid spikes in blood glucose levels. They provide little to no nutritional value.
White Bread and Pastries: These are high in refined carbohydrates and low in fiber, leading to quick increases in blood sugar. Examples include white bread, bagels, muffins, and other baked goods made from white flour.
Processed Snack Foods: Chips, crackers, and other packaged snacks often contain refined carbs, unhealthy fats, and added sugars, all of which can negatively impact blood sugar levels.
Sugary Cereals: Many breakfast cereals, even those marketed as healthy, contain high amounts of added sugars and refined grains, which can lead to blood sugar spikes.
Candy and Sweets: Candies, cookies, cakes, and other desserts are packed with sugar and can quickly raise blood glucose levels. Opt for healthier treats like fresh fruit or dark chocolate in moderation.
To manage blood sugar effectively, focus on a balanced diet rich in whole grains, lean proteins, healthy fats, and plenty of vegetables. For additional support, consider incorporating blood sugar supplements into your routine.
A blood sugar level of 135 mg/dL in the morning, especially if it is a fasting reading (no food for at least 8 hours), is considered slightly elevated. The normal fasting blood sugar range for most people without diabetes is 70 to 99 mg/dL. For individuals with diabetes, a fasting blood sugar target is often between 80 to 130 mg/dL.
A reading of 135 mg/dL may indicate that your blood sugar levels are not optimally controlled, and it’s important to discuss this with your healthcare provider. They can help you determine the cause and make necessary adjustments to your diet, exercise, or medication regimen to better manage your blood sugar levels.
Three hours after eating, blood sugar levels should ideally have returned closer to the pre-meal range. For most people without diabetes, blood sugar levels should be less than 140 mg/dL two hours after the start of a meal. By the three-hour mark, it would generally be expected to be even lower, approaching the normal fasting range of 70 to 99 mg/dL.
For individuals with diabetes, the target may vary based on their treatment plan, but a typical goal is to have blood sugar levels less than 180 mg/dL two hours after eating. At three hours, it should be getting closer to their target range as advised by their healthcare team. Monitoring your blood sugar levels and consulting with your healthcare provider can help ensure they are within a healthy range.
When blood sugar levels are too high, a condition known as hyperglycemia, you may experience a variety of symptoms. These can develop gradually and may include:
- Increased Thirst: Feeling very thirsty despite drinking plenty of fluids.
- Frequent Urination: Needing to urinate more often than usual, including waking up at night to go to the bathroom.
- Fatigue: Feeling unusually tired or weak, even with adequate rest.
- Blurred Vision: Difficulty seeing clearly, as high blood sugar levels can affect the lenses in your eyes.
- Headaches: Experiencing frequent headaches or a feeling of pressure in the head.
- Dry Mouth: A persistent dry mouth or feeling of dehydration.
- Hunger: Increased hunger, even after eating.
- Slow-Healing Sores: Cuts or wounds that take longer to heal than usual.
- Irritability: Feeling more irritable or having mood swings.
If you experience these symptoms frequently, it’s important to check your blood sugar levels and consult with your healthcare provider. They can help determine the cause and make necessary adjustments to your diabetes management plan. High blood sugar levels over time can lead to serious complications, so maintaining control is crucial. Incorporating blood sugar supplements can also help in managing and maintaining healthy blood sugar levels.
A blood sugar level of 170 mg/dL, particularly if it is not after a meal, can indicate that your blood sugar is higher than the recommended target. Here are steps you can take to manage it:
Stay Hydrated: Drink water to help your body eliminate excess glucose through urine.
Exercise: Light to moderate physical activity can help lower blood sugar levels. Activities like walking or light jogging can be effective, but always consult with your healthcare provider before starting a new exercise routine, especially if you have other health conditions.
Review Your Diet: Check what you’ve eaten recently and avoid high-sugar and high-carb foods. Opt for foods with a low glycemic index (GI) that have less impact on blood sugar levels.
Medications: If you take medication for diabetes, ensure you are following your prescribed regimen. If you missed a dose, follow your healthcare provider’s instructions on what to do next.
Monitor Your Blood Sugar: Continue to monitor your blood sugar levels to see if they decrease. Frequent monitoring can help you understand how your body responds to different activities and foods.
Consult Your Healthcare Provider: If high blood sugar levels persist or you experience symptoms like excessive thirst, frequent urination, fatigue, or blurred vision, contact your healthcare provider. They may need to adjust your treatment plan.
Incorporating blood sugar supplements into your routine can also help maintain healthy blood sugar levels. Always consult your healthcare provider before starting any new supplement.
