How Can I Treat High Blood Sugar
Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:
- Be more active. Regular exercise can help keep your blood sugar levels on track. Important: dont exercise if ketones are present in your urine. This can make your blood sugar go even higher.
- Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
- Follow your diabetes meal plan. Ask your doctor or dietitian for help if youre having trouble sticking to it.
- Check your blood sugar as directed by your doctor. Check more often if youre sick or if youre concerned about high or low blood sugar.
- Talk to your doctor about adjusting how much insulin you take and what types of insulin to use.

If your doctor thinks you have type 1 diabetes, your blood may also tested for autoantibodies that are often present in type 1 diabetes but not in type 2 diabetes. You may have your urine tested for ketones , which also indicate type 1 diabetes instead of type 2 diabetes.
Still Frustrated With Your Blood Sugar And A1c Results
Your blood sugars and your insulin or medication needs never stay in one place. If you gain weight or lose weight, your insulin and medication needs will change. If you become more active or less active, your needs will change. If you make drastic or even small changes to your nutrition, your needs will change!
Working with your diabetes healthcare team, and diabetes coaches who can teach you how to make changes in your overall diabetes management plan are essential. Diabetes is a lifelong learning process.
Take a deep breath and be patient. If you dont like what youre seeing on your glucose meter, dont get madget studying! Take good notes and work with your team to make changes to reach your goals.

Low Blood Sugar Symptoms
Hypoglycemia happens when blood glucose levels drop too low. Low blood sugar can be caused by many things including the two different types of diabetes, certain medications, alcohol, endocrine disorders, eating disorders, pregnancy , and disorders of the liver, kidneys, or heart.
Here are some of the most common symptoms that someone with low blood sugar might experience:
- Tingling lips
If your blood sugar is low you might start to feel some of the first signs of hypoglycemia like dizziness, lightheadedness, or sweating. The only way to know for sure if your blood sugar is low is to test it with a glucose meter or other glucose monitoring device.
If you dont have access to these tools and start to feel the symptoms of low blood sugar, consume 15 grams of carbs or take a quick dissolve glucose tablet to raise your blood sugar levels and avoid further symptoms, according to the American Diabetes Association . Once your blood sugar is back in its target range, you can have a snack or meal to make sure it doesnt drop again.
Here are some other lifestyle and medicinal treatments that can help treat hypoglycemia:
- Eat a healthy diet full of whole foods that are minimally processed.
- Take prediabetes or diabetes medications as recommended by your healthcare provider.
- Use a glucagon kit in emergencies. Glucagon is a hormone that raises blood sugar levels quickly.
Why The Test Is Performed
Your health care provider may order this test if you have signs of diabetes . More than likely, the provider will order a fasting blood sugar test.
The blood glucose test is also used to monitor people who already have diabetes.
The test may also be done if you have:
- An increase in how often you need to urinate
- Recently gained a lot of weight
- Blurred vision
SCREENING FOR DIABETES
This test may also be used to screen a person for diabetes.
High blood sugar and diabetes may not cause symptoms in the early stages. A fasting blood sugar test is almost always done to screen for diabetes.
If you are over age 45, you should be tested every 3 years.
If you’re overweight and have any of the risk factors below, ask your provider about getting tested at an earlier age and more often:
- High blood sugar level on a previous test
- Blood pressure of 140/90 mm Hg or higher, or unhealthy cholesterol levels
- History of heart disease
- Member of a high-risk ethnic group
- Woman who has been previously diagnosed with gestational diabetes
- Polycystic ovary disease
- Close relative with diabetes
- Not physically active
Children age 10 and older who are overweight and have at least two of the risk factors listed above should be tested for type 2 diabetes every 3 years, even if they have no symptoms.

How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted
To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test. When you report to the clinic or laboratory, a small sample of blood will be taken from a vein in your arm. According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:
Fasting blood glucose level
- If your blood glucose level is 70 to 99* mg/dL . . .
- What it means: Your glucose level is within the normal range
*Values between 50 and 70 are often seen in healthy people
**The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders
Last reviewed by a Cleveland Clinic medical professional on 02/21/2018.
Who Is Most At Risk For Developing Diabetes
The following categories of people are considered “high-risk” candidates for developing diabetes:
- Individuals who are overweight or obese
- Individuals who are 45 years of age or older
- Individuals with first-degree relatives with diabetes
- Individuals who are African-American, Alaska Native, American Indian, Asia American, Hispanic/Latino, Native Hawaiian, Pacific Islanders,
- Women who developed diabetes while they were pregnant or gave birth to large babies
- Individuals with high blood pressure
- Individuals with high-density lipoprotein below 25 mg/dl or triglyceride levels at or above 250 mg/dl
- Individuals who have impaired fasting glucose or impaired glucose tolerance
- Individuals who are physically inactive engaging in exercise less than three times a week
- Individuals who have polycystic ovary syndrome, also called PCOS
- Individuals who have acanthosis nigricans — dark, thick and velvety skin around your neck or armpits
In addition to testing the above individuals at high risk, the American Diabetes Association also recommends screening all individuals age 45 and older.

Why Your A1c Matters
In a nutshell: your A1c is one of the clearest indicators of your risk for developing diabetes complications like neuropathy , retinopathy , nephropathy , and severe infection in any part of your body that requires healing.
For instance, a small cut on your toe could become infected due to high blood sugars, struggle to heal, and become severe enough that the infection could lead to an amputation.
The general guidelines from the American Diabetes Association recommend an A1c at or below 7.0 percent for the best prevention of diabetes complications. Your risk of developing a diabetes complication continues to drop as your A1c drops closer to 6 percent.
Some people with diabetes aim for A1c levels in the 5s and lower especially those who follow strict low-carb diets like the ketogenic diet and the Bernstein diet. However, this hasnt been proven in research as especially necessary, nor is it reasonably achievable for the larger population of people with diabetes.
Its also important to remember that your blood sugar levels and your A1c are just information that tells you whether your body needs more or less of factors like insulin, other diabetes medications, changes in your nutrition, and changes in your exercise.
If you dont like the number youre seeing on your glucose meter or your A1c results, use that number as motivation to make changes in how you safely manage your diabetes in order to get different results.
Determining The Right A1c Goal For You
Just because a normal blood sugar range of 70 to 130 mg/dL is considered the healthiest doesnt necessarily mean thats the appropriate goal range for you especially if you have type 1 diabetes, or take insulin as a person with type 2 diabetes.
The reason this may not be the right goal for you is that extremely tight blood sugar management in people taking insulin can potentially lead to frequent low blood sugars which can be dangerous.
Achieving extremely tight blood sugar management, like a range of 70 to 130 mg/dL, also often requires a strict nutrition plan, more frequent than usual blood sugar monitoring, precise medication management, and most importantly, years of experience studying your own blood sugar levels.

How Can Continuous Glucose Monitoring Help You Maintain Optimal Glucose Levels
It is not uncommon for your glucose levels to increase after a meal: you just ate food that may contain glucose, and now your body is working on getting it out of the bloodstream and into the cells. We know that we want to prevent excessive spiking of glucose levels because studies show that high post-meal glucose spikes over 160 mg/dl are associated with higher cancer rates. Spikes are also associated with heart disease. Repeated high glucose spikes after meals contribute to inflammation, blood vessel damage, increased risk of diabetes, and weight gain. Additionally, the data shows that the big spikes and dips in glucose are more damaging to tissues than elevated but stable glucose levels. Therefore, you should strive to keep your glucose levels as steady as possible, at a low and healthy baseline level, with minimal variability after meals.
Keeping your glucose levels constant is more complicated than just following a list of eat this, avoid that foods. Each person has an individual response to food when it comes to their glucose levels studies have shown that two people can have different changes in their glucose levels after eating identical foods. The difference can be quite dramatic. One study found that some people had equal and opposite post-meal glucose spikes in response to the same food.
Your Blood Sugar Isnt Just Because Of What You Eat
Mainstream media would have you believe that your blood sugar levels are impacted only by what you eat and how much you exercise, but people with type 1 and type 2 diabetes who test their blood sugars frequently could tell you otherwise.
Its especially important to keep this mind when looking at your own blood sugars and your goals because there are certain variables and challenges that impact blood sugar levels that you cant always control.
- Menstrual cycles: raises blood sugar and insulin needs
- Adrenaline rushes from competitive sports, heated arguments, rollercoaster rides: raises blood sugar and insulin needs
- The common cold and other illnesses: usually raises blood sugar and insulin needs
- Hormonal changes due to puberty and healthy growth in young adults: raises blood sugar and insulin needs
- An injury which raises overall inflammation levels: raises blood sugar and insulin needs
- Glucogenesis during anaerobic exercise: raises blood sugar
While you cant necessarily prevent these factors that affect your blood sugar from occurring, you can work with your diabetes healthcare team to adjust your insulin, other diabetes medications, nutrition and activity levels to help compensate for them when they do occur.
For example, when engaging in anaerobic exercise like weightlifting many people with type 1 diabetes find it necessary to take a small bolus of insulin prior to or during their workout because anaerobic exercise can actually raise blood sugar.

Blood sugar or glucose is released after consumption and breakdown of carbohydrates during food intake. It is the main sugar that is found in your bloodstream and its regulation is undertaken by pancreatic secretions . Normal blood sugar levels chart for most adults ranges from 80 to 99 mg of sugar per deciliter before a meal and 80 to 140 mg per deciliter after meals.

Blood Sugar Target Levels For Nonpregnant Adults With Diabetes
From the 2017 American Diabetes Association Standards of Care, the following chart shows current targets for blood sugars for nonpregnant adult patients with diabetes:
Summary of Glycemic Recommendations for Adults with Diabetes
|A1C < 7.0%|
|Preprandial capillary plasma glucose 80130 mg/dL*|
|Peak postprandial capillary plasma glucose < 180 mg/dL*|
|*More or less stringent glycemic goals may be appropriate for individual patients. Goals should be individualized|
|**based on duration of diabetes, age/life expectancy, comorbid conditions, known CVD or advancedmicrovascular complications, hypoglycemia unawareness, and individual patient considerations.Postprandial glucose may be targeted|
Blood sugar target levels for nonpregnant adults with diabetes coincide with A1C less than 7
An A1C less than 7 percent is the guideline for adults with diabetes, and the target ranges of 80-130 mg/dl fasting or pre-meal, and 80-180 mg/dl after meals corresponds with an A1C of less than 7 percent.
I suggest you read the following articles:
These values represent what research has shown to be the optimal blood sugar targets for nonpregnant adults to avoid complications of diabetes in the long term. Less than 70 mg/dl is considered a low blood sugar, or hypoglycemia, and the newest guideline consider that you want to catch a low blood sugar before it occurs.
Who Should Do The Test
According to the American Diabetes Association, screening for diabetes is recommended in people over 45 , or at any age if you have certain risk factors, including :
- Being overweight, obese, or physically inactive
- Having a close relative with diabetes
- Belonging to a certain race/ethnic group
- Having signs of insulin resistance or conditions associated with insulin resistance, such as high blood pressure , low good cholesterol and/or high triglycerides , and polycystic ovary syndrome
- Having had diabetes in pregnancy

Causes Of Impaired Fasting Glycaemia
IFG develops if your body becomes unable to control glucose levels. Your body may be unable to use insulin properly or produce less insulin. There are a number of factors that may make you more likely to develop IFG. If youre black or South Asian and over 25, or if youre white and over 40, and you have one or more of the following risk factors, then you may be at risk of IFG:
- one of your parents, brother or sister has type 2 diabetes
- youre overweight or you carry extra weight around your middle rather than your hips and thighs
- you have high blood pressure or you have had a heart attack or stroke
- you have polycystic ovary syndrome and you are overweight
- you have had diabetes during pregnancy
- you have severe mental health problems
Normal Blood Sugar Levels For Adults With Diabetes
But if you have diabetes, your body doesnât make insulin or doesnât respond to it normally . That can leave your blood sugar too high for too long. Over time, that can damage nerves and blood vessels and lead to heart disease and other problems.
If you have diabetes, your doctor may ask you to keep track of your blood sugar by testing it at home with a special device called a blood glucose monitor or home blood sugar meter. It takes a small sample of blood, usually from the tip of your finger, and measures the amount of glucose in it.
Follow your doctorâs instructions about the best way to use your device.
Your doctor will tell you when and how to test your blood sugar. Each time you do it, log it in a notebook or online tool or in an app. The time of day, recent activity, your last meal, and other things can all affect whether a reading will be of concern to your doctor. So try to log relevant information like:
- What medication and dosage you took
- What you ate, when you ate, or whether you were fasting
- How much, how intense, and what kind of exercise you were doing, if any
That will help you and your doctor see how your treatment is working.
