Diagnosis

Symptoms of type 1 diabetes often appear 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 evident, the American Diabetes Association (ADA) has recommended screening guidelines. The ADA recommends that the following people be screened for diabetes:

Glycated hemoglobin (A1C) test. This blood test, which doesn't require fasting, indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to hemoglobin, the oxygen-carrying protein in red blood cells.

The higher your blood sugar levels, the more hemoglobin you'll have with sugar attached. An A1C level of 6.5 percent or higher on two separate tests indicates that you have diabetes. An A1C between 5.7 and 6.4 percent indicates prediabetes. Below 5.7 is considered normal.

If the A1C test results aren't consistent, the test isn't available, or you have certain conditions that can make the A1C test inaccurate such as if you're pregnant or have an uncommon form of hemoglobin (known as a hemoglobin variant) your doctor may use the following tests to diagnose diabetes:

Oral glucose tolerance test. For this test, you fast overnight, and the fasting blood sugar level is measured. Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours.

A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.

If type 1 diabetes is suspected, your urine will be tested to look for the presence of a byproduct produced when muscle and fat tissue are used for energy because the body doesn't have enough insulin to use the available glucose (ketones). Your doctor will also likely run a test to see if you have the destructive immune system cells associated with type 1 diabetes called autoantibodies.

Your doctor will likely evaluate your risk factors for gestational diabetes early in your pregnancy:

Your doctor may use the following screening tests:

Initial glucose challenge test. You'll begin the glucose challenge test by drinking a syrupy glucose solution. One hour later, you'll have a blood test to measure your blood sugar level. A blood sugar level below 140 mg/dL (7.8 mmol/L) is usually considered normal on a glucose challenge test, although this may vary at specific clinics or labs.

If your blood sugar level is higher than normal, it only means you have a higher risk of gestational diabetes. Your doctor will order a follow-up test to determine if you have gestational diabetes.

Follow-up glucose tolerance testing. For the follow-up test, you'll be asked to fast overnight and then have your fasting blood sugar level measured. Then you'll drink another sweet solution this one containing a higher concentration of glucose and your blood sugar level will be checked every hour for a period of three hours.

If at least two of the blood sugar readings are higher than the normal values established for each of the three hours of the test, you'll be diagnosed with gestational diabetes.

Depending on what type of diabetes you have, blood sugar monitoring, insulin and oral medications may play a role in your treatment. Eating a healthy diet, maintaining a healthy weight and participating in regular activity also are important factors in managing diabetes.

An important part of managing diabetes as well as your overall health is maintaining a healthy weight through a healthy diet and exercise plan:

Healthy eating. Contrary to popular perception, there's no specific diabetes diet. You'll need to center your diet on more fruits, vegetables, lean proteins and whole grains foods that are high in nutrition and fiber and low in fat and calories and 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, as long as they're counted as part of your meal plan.

Yet 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.

Physical activity. Everyone needs regular aerobic exercise, and people who have diabetes are no exception. Exercise lowers your blood sugar level by moving sugar into your cells, where it's used for energy. Exercise also increases your sensitivity to insulin, which means your body needs less insulin to transport sugar to your cells.

Get your doctor'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 aerobic exercise most days of the week. Bouts of activity can be as brief as 10 minutes, three times a day. If you haven't been active for a while, start slowly and build up gradually.

Treatment for type 1 diabetes involves insulin injections or the use of an insulin pump, frequent blood sugar checks, and carbohydrate counting. Treatment of type 2 diabetes primarily involves lifestyle changes, monitoring of your blood sugar, along with diabetes medications, insulin or both.

Monitoring your blood sugar. 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 monitoring 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 frequently.

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 meter, it can significantly reduce 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, stress and for women, fluctuations in hormone levels.

In addition to daily blood sugar monitoring, your doctor will likely recommend regular A1C testing to measure your average blood sugar level for the past two to three months.

Compared with repeated daily blood sugar tests, A1C testing better indicates how well your diabetes treatment plan is working overall. An elevated A1C level may signal the need for a change in your oral medication, 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. However, for most people with diabetes, the American Diabetes Association recommends an A1C of below 7 percent. Ask your doctor what your A1C target is.

Insulin. People with type 1 diabetes need insulin therapy to survive. Many people with type 2 diabetes or gestational diabetes also need insulin therapy.

Many types of insulin are available, including rapid-acting insulin, long-acting insulin and intermediate options. Depending on your needs, your doctor may prescribe a mixture of insulin types to use throughout the day and night.

Insulin can't be taken orally to lower blood sugar because stomach enzymes interfere with insulin's action. Often insulin is 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 cellphone worn on the outside of your body. A tube connects the reservoir of insulin to a catheter that's inserted under the skin of your abdomen.

A tubeless pump that works wirelessly also is now available. You program an insulin pump to dispense specific amounts of insulin. It can be adjusted to deliver more or less insulin depending on meals, activity level and blood sugar level.

An emerging treatment approach, not yet available, is closed loop insulin delivery, also known as the artificial pancreas. It links a continuous glucose monitor to an insulin pump, and automatically delivers the correct amount of insulin when needed.

There are a number of versions of the artificial pancreas, and clinical trials have had encouraging results. More research needs to be done before a fully functional artificial pancreas receives regulatory approval.

However, progress has been made toward an artificial pancreas. In 2016, an insulin pump combined with a continuous glucose monitor and a computer algorithm was approved by the Food and Drug Administration. However, the user still needs to tell the machine how many carbohydrates will be eaten.

Oral or other medications. Sometimes other oral or injected medications are prescribed as well. Some diabetes medications stimulate your pancreas to produce and release more insulin. Others inhibit the production and release of glucose from your liver, which means you need less insulin to transport sugar into your cells.

Still others block the action of stomach or intestinal enzymes that break down carbohydrates or make your tissues more sensitive to insulin. Metformin (Glucophage, Glumetza, others) is generally the first medication prescribed for type 2 diabetes.

Transplantation. 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, which is why transplants are usually reserved for people whose diabetes can't be controlled or those who also need a kidney transplant.

Bariatric surgery. Although it is not specifically considered a treatment for type 2 diabetes, people with type 2 diabetes who are obese and have a body mass index higher than 35 may benefit from this type of surgery. People who've undergone gastric bypass have seen significant improvements in their blood sugar levels. However, 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 and avoiding complications during delivery. In addition to maintaining a healthy diet and exercising, your treatment plan may include monitoring your blood sugar and, in some cases, using insulin or oral medications.

Your doctor also will monitor your blood sugar level during labor. If your blood sugar rises, your baby may release high levels of insulin which can lead to low blood sugar right after birth.

If you have prediabetes, healthy lifestyle choices can help you bring your blood sugar level back to normal or at least keep it from rising toward the levels seen in type 2 diabetes. Maintaining a healthy weight through exercise and healthy eating can help. Exercising at least 150 minutes a week and losing about 7 percent of your body weight may prevent or delay type 2 diabetes.

Sometimes medications such as metformin (Glucophage, Glumetza, others) also are an option if you're at high risk of diabetes, including when your prediabetes is worsening or if you have cardiovascular disease, fatty liver disease or polycystic ovary syndrome.

In other cases, medications to control cholesterol statins, in particular and high blood pressure medications are needed. Your doctor might prescribe low-dose aspirin therapy to help prevent cardiovascular disease if you're at high risk. However, healthy lifestyle choices remain key.

Because so many factors can affect your blood sugar, problems may sometimes arise that require immediate care, such as:

Increased ketones in your urine (diabetic ketoacidosis). If your cells are starved for energy, your body may begin to break down fat. This produces toxic acids known as ketones. Watch for loss of appetite, weakness, vomiting, fever, stomach pain and a sweet, fruity breath.

You can check your urine for excess ketones with an over-the-counter ketones test kit. If you have excess ketones in your urine, consult your doctor right away or seek emergency care. This condition is more common in people with type 1 diabetes.

Hyperglycemic hyperosmolar nonketotic syndrome. Signs and symptoms of this life-threatening condition include a blood sugar reading over 600 mg/dL (33.3 mmol/L), dry mouth, extreme thirst, fever, drowsiness, confusion, vision loss and hallucinations. Hyperosmolar syndrome is caused by sky-high blood sugar that turns blood thick and syrupy.

It is seen in people with type 2 diabetes, and it's often preceded by an illness. Call your doctor or seek immediate medical care if you have signs or symptoms of this condition.

Low blood sugar (hypoglycemia). If your blood sugar level drops below your target range, it's known as low blood sugar (hypoglycemia). If you're taking medication that lowers your blood sugar, including insulin, your blood sugar level can drop for many reasons, including skipping a meal and getting more physical activity than normal. Low blood sugar also occurs if you take too much insulin or an excess of a glucose-lowering medication that promotes the secretion of insulin by your pancreas.

Check your blood sugar level regularly, and watch for signs and symptoms of low blood sugar sweating, shakiness, weakness, hunger, dizziness, headache, blurred vision, heart palpitations, irritability, slurred speech, drowsiness, confusion, fainting and seizures. Low blood sugar is treated with quickly absorbed carbohydrates, such as fruit juice or glucose tablets.

Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease.

Diabetes is a serious disease. Following your diabetes treatment plan takes round-the-clock commitment. Careful management of diabetes can reduce your risk of serious even life-threatening complications.

Make physical activity part of your daily routine. Regular exercise can help prevent prediabetes and type 2 diabetes, and it can help those who already have diabetes to maintain better blood sugar control. A minimum of 30 minutes of moderate exercise such as brisk walking most days of the week is recommended.

A combination of exercises aerobic exercises, such as walking or dancing on most days, combined with resistance training, such as weightlifting or yoga twice a week often helps control blood sugar more effectively than does either type of exercise alone.

It's also a good idea 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.

In addition, if you have type 1 or type 2 diabetes:

Keep your vaccinations up-to-date. High blood sugar can weaken your immune system. Get a flu shot every year, and your doctor may recommend the pneumonia vaccine, as well. The Centers for Disease Control and Prevention (CDC) also currently recommends hepatitis B vaccination if you haven't previously been vaccinated against hepatitis B and you're an adult ages 19 to 59 with type 1 or type 2 diabetes.

The most recent CDC guidelines advise vaccination as soon as possible after diagnosis with type 1 or type 2 diabetes. If you are age 60 or older, have diabetes, and haven't previously received the vaccine, talk to your doctor about whether it's right for you.

If you drink alcohol, do so responsibly. Alcohol can cause either high or low blood sugar, depending 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 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.

Numerous substances have been shown to improve insulin sensitivity in some studies, while 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 with blood sugar management.

If you decide to try any type of alternative therapy, don't stop taking the medications that your doctor has prescribed. Be sure to discuss the use of any of these therapies with your doctor to make sure that they won't cause adverse reactions or interact with your current therapy.

Additionally, there are no treatments alternative or conventional that can cure diabetes, so it's critical that people who are receiving insulin therapy for diabetes don't stop using insulin unless directed to do so by their physicians.

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 doctor.

Because good diabetes management can be time-consuming, and sometimes overwhelming, some people find it helps to talk to someone. Your doctor 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 your 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 doctor may know of a local support group, or you can call the American Diabetes Association at 800-DIABETES (800-342-2383) or the Juvenile Diabetes Research Foundation at 800-533-CURE (800-533-2873).

You're likely to start by seeing your primary care doctor if you're having diabetes symptoms. If your child is having diabetes symptoms, you might see your child's pediatrician. If blood sugar levels are extremely 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 doctor who specializes in diabetes, among other disorders (endocrinologist). Soon after diagnosis, you'll also likely meet with a diabetes educator and a dietitian to get more information on managing your diabetes.

Here's some information to help you get ready for your appointment and to know what to expect.

Preparing a list of questions can help you make the most of your time with your doctor. For diabetes, some questions to ask include:

Your doctor is likely to ask you a number of questions, such as:
