Your overall health and well-being depend on your ability to control blood sugar levels. Whether you’re actively managing diabetes, dealing with prediabetic conditions, or simply striving for a balanced lifestyle, having a grasp of the range of blood sugar levels proves beneficial.
This comprehensive guide explores what constitutes normal blood sugar levels, what qualifies as high or dangerous levels, and how to manage them effectively. Additionally, we’ll provide practical tips, a blood sugar log for reference, and insights into the risks of high blood sugar.
For some, even using dietary supplements like glucose has been helpful in maintaining healthy blood sugar levels. This supplement also boosts your energy and helps you manage your weight.
Knowledge empowers, and it can be life-changing in the case of blood sugar levels. Let’s embark on this journey towards better health and blood sugar control.
What is a Normal Blood Sugar Level?
The normal blood sugar level, measured in milligrams per deciliter (mg/dL), typically ranges between 70 and 99 mg/dL when fasting or if you haven’t eaten in the last 8 to 12 hours. After a meal (postprandial), a healthy range is under 140 mg/dL.,
These levels are essential for providing energy to the body’s cells, particularly the brain. When blood sugar remains within this range, it shows sugar is being processed efficiently. It also means your body is making enough insulin to manage your sugars.
Monitoring and maintaining normal blood sugar levels helps prevent complications associated with high or low levels, especially if you’re diabetic.
What constitutes High Blood Sugar Levels?
High blood sugar, also known as hyperglycemia, occurs when blood sugar levels exceed the normal range. When fasting, a reading above 126 mg/dL indicates elevated blood sugar. If you aren’t diabetic, 2 hours after eating, your blood sugar should be below 140.
For someone with diabetes, anything over 130 mg/dL for fasting blood sugar is high. After meals, blood sugar levels should not exceed 180 mg/dL. Blood sugar levels between the normal and high ranges mean you may have prediabetes. 
Leaving your blood sugar levels high for too long leads to serious health complications, particularly for individuals with diabetes. You want to work to control blood sugar levels to avoid these issues.
What are the Symptoms of High or Low Blood Sugar Levels?
1. High Blood Sugar (Hyperglycemia):
When blood sugar levels increase, your body will start to signal that your numbers are getting high. Symptoms of high blood sugar levels include:
- excessive thirst
- frequent urination
- blurred vision
- unexplained weight loss
In severe cases, hyperglycemia leads to diabetic ketoacidosis (DKA), a life-threatening condition caused by the build-up of ketones in the blood. Ketones are produced by the liver during the breakdown of fat. They can be used by cells, including the brain, for energy. Too many ketones result in someone falling into a coma or dying if not treated.
2. Low Blood Sugar (Hypoglycemia):
On the other hand, low blood sugar also has distinct signs. These may include4:
- sudden hunger
- trembling or shakiness
In severe cases, it can progress to loss of consciousness or seizures. Recognizing these symptoms quickly is crucial for timely action.
Have you heard of the 15-15 rule? If your blood sugar drops below 70 or you’re experiencing low blood sugar symptoms, you want to eat or drink 15 grams of carbohydrates and recheck your sugar in 15 minutes. If your sugar is still low after 15 minutes, repeat these steps.,
Examples of 15 grams of carbohydrates include:
- 4 ounces (½ cup) of regular soda or juice
- 1 tablespoon of sugar, honey, or syrup
- Hard candies, jellybeans, or gumdrops (see food label for how much to eat)
- 3-4 glucose tablets
- 1 dose of glucose gel (usually 1 tube)
Regular monitoring and understanding of your body’s signals can help control blood sugar levels within a safe range.
When are Blood Sugar Levels Considered Dangerous?
Dangerously high blood sugar levels typically exceed 250 mg/dL. At this point, the risk of severe complications increases. If blood sugar levels are left this high for too long, this leads to diabetic emergencies like hyperosmolar hyperglycemic state (HHS) or diabetic ketoacidosis (DKA).
These conditions require immediate medical attention and can be life-threatening if left untreated. It’s important for individuals with diabetes to closely monitor their blood sugar levels and take proactive steps to keep them within a safe range.
What is a Blood Sugar Log?
A blood sugar log visually represents blood glucose levels across different times of the day. An example blood sugar log can be found here. It typically includes:
- Time Periods: The log should cover fasting levels (before meals), postprandial levels (after meals), and possibly other specific times like before bedtime.
- Blood Sugar Ranges: Clearly indicate the normal range, high range, and dangerously high range for both fasting and postprandial levels.
- Dates and Days: Include dates or days of the week for tracking trends over time.
- Additional Notes: Provide space for you to jot down any relevant information, such as medication dosages or lifestyle factors.
Remember, the log serves as a helpful tool for you to monitor and control your blood sugar levels. If you’re diabetic, you should bring your blood sugar log to your doctor’s appointments to review your readings. This is helpful when deciding on how to help you reach your health goals.
Tips for Avoiding High or Low Blood Sugar Levels
Here are some tips to control blood sugar levels:
- Balanced Diet: A well-balanced diet rich in whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. This helps stabilize blood sugar levels.
- Regular Monitoring: Frequently check your blood sugar levels, especially during critical times like before meals and after physical activity.
- Consistent Meal Times: Stick to regular meal times to control blood sugar levels. Avoid skipping meals to prevent sudden drops. Taking Gluctose blood sugar support supplement with your meal can also help.
- Carbohydrate Management: Monitor carbohydrate intake, aiming for complex carbs with a low glycemic index. Gluctose also helps maintain a glycemic index, which leads to slower sugar absorption.
- Physical Activity: Engage in regular exercise as it aids in insulin sensitivity and helps regulate blood sugar. Consult a healthcare provider for a tailored plan.
- Stay Hydrated: Ensure you’re staying hydrated, but limit sugary drinks. Water is the best choice to maintain optimal hydration levels.
- Medication Adherence: If prescribed, take medications or insulin as directed by your healthcare provider to control your blood sugar levels.
- Stress Management: Practice relaxation techniques like meditation, deep breathing, or yoga to mitigate stress, which can impact blood sugar.
- Sleep Quality: Aim for sufficient, restful sleep. Poor sleep patterns can affect insulin sensitivity and blood sugar control.
- Regular Check-ups: Attend regular medical check-ups to monitor blood sugar trends and receive professional guidance.
While these tips are intended to help you maintain your blood sugars, it’s best to work with your healthcare provider to tailor a plan specifically for you.
What are the risks associated with high blood sugar?
Elevated blood sugar levels, if left uncontrolled, can lead to a range of serious health complications:
- Cardiovascular Issues: High blood sugar damages blood vessels and increases the risk of heart disease, stroke, and high blood pressure.
- Kidney Damage: Prolonged hyperglycemia decreases kidney function, potentially leading to chronic kidney disease or even kidney failure. This may lead to dialysis.
- Nerve Damage (neuropathy): Nerve damage is a common consequence of uncontrolled high blood sugar, resulting in symptoms like tingling, numbness, and pain in arms and legs.
- Changes in vision (retinopathy): High blood sugar can damage the blood vessels in the eyes, leading to changes in or potential loss of vision.
- Foot Complications: Poor blood sugar control may lead to reduced blood flow and nerve damage in the feet, increasing the risk of infections, ulcers, and amputations.
- Skin Conditions: Skin problems, including bacterial and fungal infections, occur more often in individuals with high blood sugar.
- Weakened Immune System: Hyperglycemia impairs the body’s ability to fight off infections, making you more susceptible to illnesses.
- Slow Wound Healing: High blood sugar can hinder the body’s ability to heal wounds, increasing the risk of infections and complications.
- Proactive blood sugar management helps decrease these risks and maintain overall health.
Why are good blood sugar levels important?
Good blood sugar levels support energy production, brain function, and overall health. They help prevent damage to organs, control hormones, and regulate weight.
For those with diabetes, it minimizes the risk of diabetes-related complications. Stable blood sugar levels also mean fewer mood swings and a better quality of life. Controlling blood sugar levels is key to long-term health and a healthier life.
Frequently asked questions
What is a healthy A1C level by age?
A healthy A1C level varies with age. A target A1C is below 5.7% for most adults, indicating normal blood sugar control. However, some variability exists. A slightly higher A1C (around 6%) may be acceptable in older adults to avoid hypoglycemia. You have prediabetes if you’re A1c is between 5.7% - 6.4%. You’re A1c must be 6.5% or above to be diagnosed with diabetes. Speak with a healthcare provider to determine an appropriate target based on your health status, age, and other factors.
What are the new A1C guidelines for the elderly?
Recent guidelines suggest that a less stringent A1C target (around 7-8%) may be appropriate for older adults with multiple chronic conditions or cognitive impairment. This minimizes the risk of hypoglycemia while still maintaining reasonable blood sugar control. Individualized care and regular monitoring are necessary for managing blood sugar levels for the elderly.
Can low estrogen affect blood sugar?
Yes, low estrogen levels, as seen in menopause or certain medical conditions, can impact blood sugar control. It may lead to insulin resistance, potentially causing higher blood sugar levels. Women experiencing hormonal changes should work closely with their healthcare provider to monitor and manage blood sugar effectively.
