Type 1 diabetes Bood often start suddenly and are often the reason for checking blood sugar levels. Because symptoms of other types of diabetes and prediabetes come on more gradually or may not be easy to see, the American Diabetes Association ADA has developed screening guidelines.
The ADA recommends that the following people be screened for diabetes:. A1C test. This blood test, which doesn't require not eating for a period of time fastingshows your average blood sugar level for the past 2 to 3 months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells.
It's also called a glycated hemoglobin test. The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6. An A1C between 5. Below 5. Glucose tolerance test. For this test, you fast overnight. Then, the fasting blood sugar level is measured.
Then you drink a sugary liquid, and blood sugar levels are tested regularly for the next two hours. If your provider thinks you may have type 1 diabetes, they may test your urine to look for the presence of ketones.
Ketones are a byproduct produced when muscle and fat are used for energy. Your provider will also probably run a test to see if you have the destructive immune system cells associated with type 1 diabetes called autoantibodies.
Your provider will likely see if you're at high risk for gestational diabetes early in your pregnancy. If you're at high risk, your provider may test for diabetes at your first prenatal visit.
If you're at average risk, you'll probably be screened sometime during your second trimester. Our caring team of Mayo Clinic experts can help you with your diabetes-related health concerns Start Here. Depending on what type of diabetes you have, blood sugar monitoring, insulin and oral drugs may be part of your treatment.
Eating a healthy diet, staying at a healthy weight and getting regular physical activity also are important parts of managing diabetes. An important part of managing diabetes — as well as your overall health — is keeping a healthy weight through a healthy diet and exercise plan:.
Healthy eating. Your diabetes diet is simply a healthy-eating plan that will help you control your blood sugar. You'll need to focus your diet on more fruits, vegetables, lean proteins and whole grains. These are foods that are high in nutrition and fiber and low in fat and calories.
You'll also cut down on saturated fats, refined carbohydrates and sweets. In fact, it's the best eating plan for the entire family. Sugary foods are OK once in a while. They must be counted as part of your meal plan. Understanding what and how much to eat can be a challenge.
A registered dietitian can help you create a meal plan that fits your health goals, food preferences and lifestyle. This will likely include carbohydrate counting, especially if you have type 1 diabetes or use insulin as part of your treatment. Physical activity. Everyone needs regular aerobic activity.
This includes people who have diabetes. Physical activity lowers your blood sugar level by moving sugar into your cells, where it's used for energy. Physical activity also makes your body more sensitive to insulin.
That means your body needs less insulin to transport sugar to your cells. Get your provider's OK to exercise. Then choose activities you enjoy, such as walking, swimming or biking.
What's most important is making physical activity part of your daily routine. Aim for at least 30 minutes or more of moderate physical activity most days of the week, or at least minutes of moderate physical activity a week.
Bouts of activity can be a few minutes during the day. If you haven't been active for a while, start slowly and build up slowly. Also avoid sitting for too long. Try to get up and move if you've been sitting for more than 30 minutes. Treatment for type 1 diabetes involves insulin injections or the use of an insulin pump, frequent blood sugar checks, and carbohydrate counting.
For some people with type 1 diabetes, pancreas transplant or islet cell transplant may be an option. Treatment of type 2 diabetes mostly involves lifestyle changes, monitoring of your blood sugar, along with oral diabetes drugs, insulin or both.
Depending on your treatment plan, you may check and record your blood sugar as many as four times a day or more often if you're taking insulin. Careful blood sugar testing is the only way to make sure that your blood sugar level remains within your target range.
People with type 2 diabetes who aren't taking insulin generally check their blood sugar much less often. People who receive insulin therapy also may choose to monitor their blood sugar levels with a continuous glucose monitor.
Although this technology hasn't yet completely replaced the glucose meterit can lower the number of fingersticks necessary to check blood sugar and provide important information about trends in blood sugar levels.
Even with careful management, blood sugar levels can sometimes change unpredictably. With help from your diabetes treatment team, you'll learn how your blood sugar level changes in response to food, physical activity, medications, illness, alcohol and stress. For women, you'll learn how your blood sugar level changes in response to changes in hormone levels.
Besides daily blood sugar monitoring, your provider will likely recommend regular A1C testing to measure your average blood sugar level for the past 2 to 3 months.
Compared with repeated daily blood sugar tests, A1C testing shows better how well your diabetes treatment plan is working overall. A higher A1C level may signal the need for a change in your oral drugs, insulin regimen or meal plan.
Your target A1C goal may vary depending on your age and various other factors, such as other medical conditions you may have or your ability to feel when your blood sugar is low.
Ask your provider what your A1C target is. People with type 1 diabetes must use insulin to manage blood sugar to survive. Many people with type 2 diabetes or gestational diabetes also need insulin therapy.

Blood glucose levels -
Over time, having too much glucose in your blood can cause serious health problems diabetes complications. So if you have diabetes, it's important to keep your blood glucose levels within your target range.
What are blood glucose targets? If you have diabetes, your blood glucose target is the range you try to reach as much as possible. The typical targets are:. Your blood glucose targets may be different, depending on your age, any additional health problems you have, and other factors.
Talk with your health care team about the best target range for you. If you have diabetes, you'll likely need to check your blood glucose every day to make sure that your blood glucose numbers are in your target range.
Some people may need to check their blood glucose several times a day. Ask your health care team how often you need to check it. The most common way to check your blood glucose level at home is with a blood glucose meter.
A blood glucose meter measures the amount of glucose in a small sample of blood, usually from your fingertip. Continuous glucose monitoring CGM is another way to check your glucose levels.
Most CGM systems use a tiny sensor that is inserted under your skin. The sensor measures your glucose level every few minutes. It can show changes in your glucose level throughout the day and night. A CGM system is especially useful for people who take insulin and have problems with low blood glucose.
Your provider will also check your blood glucose with a blood test called an A1C. It checks your average blood glucose level over the past three months.
People with diabetes usually have an A1C test at least twice a year. But you may need the test more often if you aren't meeting your diabetes treatment goals. High blood glucose is called hyperglycemia.
Symptoms that your blood glucose levels may be too high include:. If you often have high blood glucose levels or symptoms of high blood glucose, talk with your health care team.
You may need a change in your diabetes meal plan , physical activity plan, or diabetes medicines. High blood glucose may also be caused by other conditions that can affect insulin or glucose levels in your blood. These conditions include problems with your pancreas or adrenal glands. Hypoglycemia , also called low blood glucose, happens when your blood glucose level drops below what is healthy for you.
Your number might be different, so check with your health care team to find out what blood glucose level is low for you. Symptoms of low blood glucose tend to come on quickly. The symptoms can be different for everyone, but they may include:. Drugs — such as metformin, statins and high blood pressure medications — may be an option for some people with prediabetes and other conditions such as heart disease.
Many factors can affect your blood sugar. Problems may sometimes come up that need care right away. High blood sugar hyperglycemia in diabetes can occur for many reasons, including eating too much, being sick or not taking enough glucose-lowering medication.
Check your blood sugar level as directed by your provider. And watch for symptoms of high blood sugar, including:. Diabetic ketoacidosis is a serious complication of diabetes.
If your cells are starved for energy, your body may begin to break down fat. This makes toxic acids known as ketones, which can build up in the blood. Watch for the following symptoms:. You can check your urine for excess ketones with a ketones test kit that you can get without a prescription.
If you have excess ketones in your urine, talk with your provider right away or seek emergency care. This condition is more common in people with type 1 diabetes. This condition is seen in people with type 2 diabetes. It often happens after an illness.
Call your provider or seek medical care right away if you have symptoms of this condition. If your blood sugar level drops below your target range, it's known as low blood sugar diabetic hypoglycemia. If you're taking drugs that lower your blood sugar, including insulin, your blood sugar level can drop for many reasons.
These include skipping a meal and getting more physical activity than normal. Low blood sugar also occurs if you take too much insulin or too much of a glucose-lowering medication that causes the pancreas to hold insulin.
Low blood sugar is best treated with carbohydrates that your body can absorb quickly, such as fruit juice or glucose tablets. There is a problem with information submitted for this request.

Following your diabetes treatment plan takes total commitment. Careful management of diabetes can lower your risk of serious or life-threatening complications.
Make physical activity part of your daily routine. Regular physical activity can help prevent prediabetes and type 2 diabetes. It can also help those who already have diabetes to maintain better blood sugar control. A minimum of 30 minutes of moderate physical activity — such as brisk walking — most days of the week is recommended.
Aim for at least minutes of moderate aerobic physical activity a week. Getting regular aerobic exercise along with getting at least two days a week of strength training exercises can help control blood sugar more effectively than does either type of exercise alone.
Aerobic exercises can include walking, biking or dancing. Resistance training can include weight training and body weight exercises. Also try to spend less time sitting still. Try to get up and move around for a few minutes at least every 30 minutes or so when you're awake.
Keep your vaccinations up to date. High blood sugar can weaken your immune system. Get a flu shot every year. Your provider may recommend the pneumonia and COVID vaccines, as well.
The Centers for Disease Control and Prevention CDC also currently recommends hepatitis B vaccination if you haven't previously had it and you're an adult ages 19 to 59 with type 1 or type 2 diabetes. The most recent CDC guidelines suggest vaccination as soon as possible after diagnosis with type 1 or type 2 diabetes.
If you are age 60 or older, have been diagnosed with diabetes, and haven't previously received the vaccine, talk to your provider about whether it's right for you.
If you drink alcohol, do so responsibly. Alcohol can cause either high or low blood sugar. This depends on how much you drink and if you eat at the same time. If you choose to drink, do so only in moderation — one drink a day for women and up to two drinks a day for men — and always with food.
Remember to include the carbohydrates from any alcohol you drink in your daily carbohydrate count. And check your blood sugar levels before going to bed.
Many substances have been shown to improve the body's ability to process insulin in some studies. Other studies fail to find any benefit for blood sugar control or in lowering A1C levels. Because of the conflicting findings, there aren't any alternative therapies that are currently recommended to help everyone to manage blood sugar.
If you decide to try any type of alternative therapy, don't stop taking the drugs that your provider has prescribed. Be sure to discuss the use of any of these therapies with your provider.
Make sure that they won't cause bad reactions or interact with your current therapy. Also, no treatments — alternative or conventional — can cure diabetes. If you're using insulin therapy for diabetes, never stop using insulin unless directed to do so by your provider.
Living with diabetes can be difficult and frustrating. Sometimes, even when you've done everything right, your blood sugar levels may rise. But stick with your diabetes management plan and you'll likely see a positive difference in your A1C when you visit your provider.
Good diabetes management can take a great deal of time and feel overwhelming. Some people find that it helps to talk to someone. Your provider can probably recommend a mental health professional for you to speak with. Or you may want to try a support group. Sharing your frustrations and triumphs with people who understand what you're going through can be very helpful.
And you may find that others have great tips to share about diabetes management. Your provider may know of a local support group. You can also call the American Diabetes Association at DIABETES or the Juvenile Diabetes Research Foundation at CURE You're likely to start by seeing your health care provider if you're having diabetes symptoms.
If your child is having diabetes symptoms, you might see your child's health care provider. If blood sugar levels are very high, you'll likely be sent to the emergency room.
If blood sugar levels aren't high enough to put you or your child immediately at risk, you may be referred to a provider trained in diagnosing and treating diabetes endocrinologist.
Soon after diagnosis, you'll also likely meet with a diabetes educator and a registered dietitian to get more information on managing your diabetes.

Depending on your needs, your provider may prescribe a mixture of insulin types to use during the day and night. Insulin can't be taken orally to lower blood sugar because stomach enzymes interfere with insulin's action. Insulin is often injected using a fine needle and syringe or an insulin pen — a device that looks like a large ink pen.
An insulin pump also may be an option. The pump is a device about the size of a small cellphone worn on the outside of your body. A tube connects the reservoir of insulin to a tube catheter that's inserted under the skin of your abdomen.

Insulin pumps are programmed to deliver specific amounts of insulin automatically and when you eat. A continuous glucose monitor, on the left, is a device that measures blood sugar every few minutes using a sensor inserted under the skin.
Insulin pumps are programmed to deliver specific amounts of insulin continuously and with food. A tubeless pump that works wirelessly is also now available. You program an insulin pump to dispense specific amounts of insulin.
It can be adjusted to give out more or less insulin depending on meals, activity level and blood sugar level. A closed loop system is a device implanted in the body that links a continuous glucose monitor to an insulin pump.
The monitor checks blood sugar levels regularly. The device automatically delivers the right amount of insulin when the monitor shows that it's needed. The Food and Drug Administration has approved several hybrid closed loop systems for type 1 diabetes.
They are called "hybrid" because these systems require some input from the user. For example, you may have to tell the device how many carbohydrates are eaten, or confirm blood sugar levels from time to time. A closed loop system that doesn't need any user input isn't available yet. But more of these systems currently are in clinical trials.
Sometimes your provider may prescribe other oral or injected drugs as well. Some diabetes drugs help your pancreas to release more insulin. Others prevent the production and release of glucose from your liver, which means you need less insulin to move sugar into your cells.
Still others block the action of stomach or intestinal enzymes that break down carbohydrates, slowing their absorption, or make your tissues more sensitive to insulin.
Metformin Glumetza, Fortamet, others is generally the first drug prescribed for type 2 diabetes. Another class of medication called SGLT2 inhibitors may be used. They work by preventing the kidneys from reabsorbing filtered sugar into the blood.
Instead, the sugar is eliminated in the urine. In some people who have type 1 diabetes, a pancreas transplant may be an option. Islet transplants are being studied as well. With a successful pancreas transplant, you would no longer need insulin therapy. But transplants aren't always successful. And these procedures pose serious risks.
You need a lifetime of immune-suppressing drugs to prevent organ rejection. These drugs can have serious side effects. Because of this, transplants are usually reserved for people whose diabetes can't be controlled or those who also need a kidney transplant.
Some people with type 2 diabetes who are obese and have a body mass index higher than 35 may be helped by some types of bariatric surgery. People who've had gastric bypass have seen major improvements in their blood sugar levels.
But this procedure's long-term risks and benefits for type 2 diabetes aren't yet known. Controlling your blood sugar level is essential to keeping your baby healthy. It can also keep you from having complications during delivery. In addition to having a healthy diet and exercising regularly, your treatment plan for gestational diabetes may include monitoring your blood sugar.
In some cases, you may also use insulin or oral drugs. Your provider will monitor your blood sugar level during labor. If your blood sugar rises, your baby may release high levels of insulin.
This can lead to low blood sugar right after birth. Treatment for prediabetes usually involves healthy lifestyle choices.
These habits can help bring your blood sugar level back to normal. Or it could keep it from rising toward the levels seen in type 2 diabetes. Keeping a healthy weight through exercise and healthy eating can help. Drugs — such as metformin, statins and high blood pressure medications — may be an option for some people with prediabetes and other conditions such as heart disease.
Many factors can affect your blood sugar. Problems may sometimes come up that need care right away. High blood sugar hyperglycemia in diabetes can occur for many reasons, including eating too much, being sick or not taking enough glucose-lowering medication.
Check your blood sugar level as directed by your provider. And watch for symptoms of high blood sugar, including:. Diabetic ketoacidosis is a serious complication of diabetes. If your cells are starved for energy, your body may begin to break down fat. This makes toxic acids known as ketones, which can build up in the blood.
Watch for the following symptoms:. You can check your urine for excess ketones with a ketones test kit that you can get without a prescription.
Before people develop type 2 diabetes, they almost always have prediabetes—blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes.
Doctors sometimes refer to prediabetes as impaired glucose tolerance IGT or impaired fasting glucose IFG , depending on what test was used when it was detected. This condition puts you at a higher risk for developing type 2 diabetes and cardiovascular disease.
Some people with prediabetes may have some of the symptoms of diabetes or even problems from diabetes already. You usually find out that you have prediabetes when being tested for diabetes.
You will not develop type 2 diabetes automatically if you have prediabetes. For some people with prediabetes, early treatment can actually return blood glucose levels to the normal range.
Glucose is an Blood glucose levels source of energy for the body. Our bodies make it, glkcose mostly Blood glucose levels comes from the goucose we eat for more information, see Food and type 1 diabetes. Your blood glucose level is the amount of glucose sugar in your blood at a given point in time. Watch our video on Understanding blood glucose blood sugar. Insulin is a hormone made in the pancreas that keeps blood glucose levels in a healthy range.
