Type 1 diabetes
Medically reviewed on Aug 7, 2017
Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy.
Different factors, including genetics and some viruses, may contribute to type 1 diabetes. Although type 1 diabetes usually appears during childhood or adolescence, it can develop in adults.
Despite active research, type 1 diabetes has no cure. Treatment focuses on managing blood sugar levels with insulin, diet and lifestyle to prevent complications.
Type 1 diabetes signs and symptoms can appear relatively suddenly and may include:
- Increased thirst
- Frequent urination
- Bed-wetting in children who previously didn't wet the bed during the night
- Extreme hunger
- Unintended weight loss
- Irritability and other mood changes
- Fatigue and weakness
- Blurred vision
When to see a doctor
Consult your doctor if you notice any of the above signs and symptoms in you or your child.
The exact cause of type 1 diabetes is unknown. Usually, the body's own immune system — which normally fights harmful bacteria and viruses — mistakenly destroys the insulin-producing (islet, or islets of Langerhans) cells in the pancreas. Other possible causes include:
- Exposure to viruses and other environmental factors
The role of insulin
Once a significant number of islet cells are destroyed, you'll produce little or no insulin. Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).
- The pancreas secretes insulin into the bloodstream.
- Insulin circulates, allowing sugar to enter your cells.
- Insulin lowers the amount of sugar in your bloodstream.
- As your blood sugar level drops, so does the secretion of insulin from your pancreas.
The role of glucose
Glucose — a sugar — is a main source of energy for the cells that make up muscles and other tissues.
- Glucose comes from two major sources: food and your liver.
- Sugar is absorbed into the bloodstream, where it enters cells with the help of insulin.
- Your liver stores glucose as glycogen.
- When your glucose levels are low, such as when you haven't eaten in a while, the liver breaks down the stored glycogen into glucose to keep your glucose levels within a normal range.
In type 1 diabetes, there's no insulin to let glucose into the cells, so sugar builds up in your bloodstream. This can cause life-threatening complications.
Some known risk factors for type 1 diabetes include:
- Family history. Anyone with a parent or sibling with type 1 diabetes has a slightly increased risk of developing the condition.
- Genetics. The presence of certain genes indicates an increased risk of developing type 1 diabetes.
- Geography. The incidence of type 1 diabetes tends to increase as you travel away from the equator.
- Age. Although type 1 diabetes can appear at any age, it appears at two noticeable peaks. The first peak occurs in children between 4 and 7 years old, and the second is in children between 10 and 14 years old.
Over time, type 1 diabetes complications can affect major organs in your body, including heart, blood vessels, nerves, eyes and kidneys. Maintaining a normal blood sugar level can dramatically reduce the risk of many complications.
Eventually, diabetes complications may be disabling or even life-threatening.
- Heart and blood vessel disease. Diabetes dramatically increases your risk of various cardiovascular problems, including coronary artery disease with chest pain (angina), heart attack, stroke, narrowing of the arteries (atherosclerosis) and high blood pressure.
Nerve damage (neuropathy). Excess sugar can injure the walls of the tiny blood vessels (capillaries) that nourish your nerves, especially in the legs. This can cause tingling, numbness, burning or pain that usually begins at the tips of the toes or fingers and gradually spreads upward. Poorly controlled blood sugar could cause you to eventually lose all sense of feeling in the affected limbs.
Damage to the nerves that affect the gastrointestinal tract can cause problems with nausea, vomiting, diarrhea or constipation. For men, erectile dysfunction may be an issue.
- Kidney damage (nephropathy). The kidneys contain millions of tiny blood vessel clusters that filter waste from your blood. Diabetes can damage this delicate filtering system. Severe damage can lead to kidney failure or irreversible end-stage kidney disease, which requires dialysis or a kidney transplant.
- Eye damage. Diabetes can damage the blood vessels of the retina (diabetic retinopathy), potentially causing blindness. Diabetes also increases the risk of other serious vision conditions, such as cataracts and glaucoma.
- Foot damage. Nerve damage in the feet or poor blood flow to the feet increases the risk of various foot complications. Left untreated, cuts and blisters can become serious infections that may ultimately require toe, foot or leg amputation.
- Skin and mouth conditions. Diabetes may leave you more susceptible to infections of the skin and mouth, including bacterial and fungal infections. Gum disease and dry mouth also are more likely.
- Pregnancy complications. High blood sugar levels can be dangerous for both the mother and the baby. The risk of miscarriage, stillbirth and birth defects increases when diabetes isn't well-controlled. For the mother, diabetes increases the risk of diabetic ketoacidosis, diabetic eye problems (retinopathy), pregnancy-induced high blood pressure and preeclampsia.
There's no known way to prevent type 1 diabetes. But researchers are working on preventing the disease or further destruction of the islet cells in people who are newly diagnosed.
Ask your doctor if you might be eligible for one of these clinical trials, but carefully weigh the risks and benefits of any treatment available in a trial.
Diagnostic tests include:
- Glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. It measures the percentage of blood sugar attached to the oxygen-carrying protein in red blood cells (hemoglobin). 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 diabetes.
If the A1C test isn't available, or if you have certain conditions that can make the A1C test inaccurate — such as pregnancy or an uncommon form of hemoglobin (hemoglobin variant) — your doctor may use these tests:
- Random blood sugar test. A blood sample will be taken at a random time and may be confirmed by repeat testing. Blood sugar values are expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Regardless of when you last ate, a random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially when coupled with any of the signs and symptoms of diabetes, such as frequent urination and extreme thirst.
- Fasting blood sugar test. A blood sample will be taken after an overnight fast. A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.
If you're diagnosed with diabetes, your doctor may also run blood tests to check for autoantibodies that are common in type 1 diabetes. These tests help your doctor distinguish between type 1 and type 2 diabetes when the diagnosis is uncertain. The presence of ketones — byproducts from the breakdown of fat — in your urine also suggests type 1 diabetes, rather than type 2.
After the diagnosis
You'll regularly visit your doctor to discuss diabetes management. During these visits, the doctor will check your A1C levels. Your target A1C goal may vary depending on your age and various other factors, but the American Diabetes Association generally recommends that A1C levels be below 7 percent, which translates to an estimated average glucose of 154 mg/dL (8.5 mmol/L).
Compared with repeated daily blood sugar tests, A1C testing better indicates how well your diabetes treatment plan is working. An elevated A1C level may signal the need for a change in your insulin regimen, meal plan or both.
In addition to the A1C test, the doctor will also take blood and urine samples periodically to check your cholesterol levels, thyroid function, liver function and kidney function. The doctor will also examine you to assess your blood pressure and will check the sites where you test your blood sugar and deliver insulin.
Treatment for type 1 diabetes includes:
- Taking insulin
- Carbohydrate, fat and protein counting
- Frequent blood sugar monitoring
- Eating healthy foods
- Exercising regularly and maintaining a healthy weight
The goal is to keep your blood sugar level as close to normal as possible to delay or prevent complications. Generally, the goal is to keep your daytime blood sugar levels before meals between 80 and 130 mg/dL (4.44 to 7.2 mmol/L) and your after-meal numbers no higher than 180 mg/dL (10 mmol/L) two hours after eating.
Insulin and other medications
Anyone who has type 1 diabetes needs lifelong insulin therapy.
Types of insulin are many and include:
- Short-acting (regular) insulin
- Rapid-acting insulin
- Intermediate-acting (NPH) insulin
- Long-acting insulin
Examples of short-acting (regular) insulin include Humulin R and Novolin R. Rapid-acting insulin examples are insulin glulisine (Apidra), insulin lispro (Humalog) and insulin aspart (Novolog). Long-acting insulins include insulin glargine (Lantus, Toujeo Solostar), insulin detemir (Levemir) and insulin degludec (Tresiba). Intermediate-acting insulins include insulin NPH (Novolin N, Humulin N).
Insulin can't be taken orally to lower blood sugar because stomach enzymes will break down the insulin, preventing its action. You'll need to receive it either through injections or an insulin pump.
Injections. You can use a fine needle and syringe or an insulin pen to inject insulin under your skin. Insulin pens look similar to ink pens and are available in disposable or refillable varieties.
If you choose injections, you'll likely need a mixture of insulin types to use throughout the day and night. Multiple daily injections that include a combination of a long-acting insulin combined with a rapid-acting insulin more closely mimic the body's normal use of insulin than do older insulin regimens that only required one or two shots a day. A regimen of three or more insulin injections a day has been shown to improve blood sugar levels.
An insulin pump. You wear this device, which is about the size of a cellphone, on the outside of your body. A tube connects a reservoir of insulin to a catheter that's inserted under the skin of your abdomen. This type of pump can be worn in a variety of ways, such as on your waistband, in your pocket or with specially designed pump belts.
There's also a wireless pump option. You wear a pod that houses the insulin reservoir on your body that has a tiny catheter that's inserted under your skin. The insulin pod can be worn on your abdomen, lower back, or on a leg or an arm. The programming is done with a wireless device that communicates with the pod.
Pumps are programmed to dispense specific amounts of rapid-acting insulin automatically. This steady dose of insulin is known as your basal rate, and it replaces whatever long-acting insulin you were using.
When you eat, you program the pump with the amount of carbohydrates you're eating and your current blood sugar, and it will give you what's called a bolus dose of insulin to cover your meal and to correct your blood sugar if it's elevated. Some research has found that in some people an insulin pump can be more effective at controlling blood sugar levels than injections. But many people achieve good blood sugar levels with injections, too. An insulin pump combined with a continuous glucose monitoring (CGM) device may provide even tighter blood sugar control.
In September 2016, the Food and Drug Administration approved the first artificial pancreas for people with type 1 diabetes who are age 14 and older. It's also called closed-loop insulin delivery. The implanted device links a continuous glucose monitor, which checks blood sugar levels every five minutes, to an insulin pump. The device automatically delivers the correct amount of insulin when the monitor indicates it's needed.
There are more artificial pancreas (closed loop) systems currently in clinical trials.
Additional medications also may be prescribed for people with type 1 diabetes, such as:
- High blood pressure medications. Your doctor may prescribe angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) to help keep your kidneys healthy. These medications are recommended for people with diabetes who have blood pressures above 140/90 millimeters of mercury (mm Hg).
- Aspirin. Your doctor may recommend you take baby or regular aspirin daily to protect your heart.
- Cholesterol-lowering drugs. Cholesterol guidelines tend to be more aggressive for people with diabetes because of the elevated risk of heart disease. The American Diabetes Association recommends that low-density lipoprotein (LDL, or "bad") cholesterol be below 100 mg/dL (2.6 mmol/L). Your high-density lipoprotein (HDL, or "good") cholesterol is recommended to be over 50 mg/dL (1.3 mmol/L) in women and over 40 mg/dL (1 mmol/L) in men. Triglycerides, another type of blood fat, are ideal when they're less than 150 mg/dL (1.7 mmol/L).
Blood sugar monitoring
Depending on what type of insulin therapy you select or require, you may need to check and record your blood sugar level at least four times a day.
The American Diabetes Association recommends testing blood sugar levels before meals and snacks, before bed, before exercising or driving, and if you suspect you have low blood sugar. Careful monitoring is the only way to make sure that your blood sugar level remains within your target range — and more frequent monitoring can lower A1C levels.
Even if you take insulin and eat on a rigid schedule, blood sugar levels can change unpredictably. You'll learn how your blood sugar level changes in response to food, activity, illness, medications, stress, hormonal changes and alcohol.
Continuous glucose monitoring (CGM) is the newest way to monitor blood sugar levels, and may be especially helpful for preventing hypoglycemia. When used by people older than 25, the devices have been shown to lower A1C.
Continuous glucose monitors attach to the body using a fine needle just under the skin that checks blood glucose level every few minutes. CGM isn't yet considered as accurate as standard blood sugar monitoring, so at this time it's still important to check your blood sugar levels manually.
Healthy eating and monitoring carbohydrates
There's no such thing as a diabetes diet. However, it's important to center your diet on nutritious, low-fat, high-fiber foods such as:
- Whole grains
Your dietitian will recommend that you eat fewer animal products and refined carbohydrates, such as white bread and sweets. This healthy-eating plan is recommended even for people without diabetes.
You'll need to learn how to count the amount of carbohydrates in the foods you eat so that you can give yourself enough insulin to properly metabolize those carbohydrates. A registered dietitian can help you create a meal plan that fits your needs.
Everyone needs regular aerobic exercise, and people who have type 1 diabetes are no exception. First, get your doctor's OK to exercise. Then choose activities you enjoy, such as walking or swimming, and make them part of your daily routine. Aim for at least 150 minutes of aerobic exercise a week, with no more than two days without any exercise. The goal for children is at least an hour of activity a day.
Remember that physical activity lowers blood sugar. If you begin a new activity, check your blood sugar level more often than usual until you know how that activity affects your blood sugar levels. You might need to adjust your meal plan or insulin doses to compensate for the increased activity.
Certain life circumstances call for different considerations.
- Driving. Hypoglycemia can occur at any time. It's a good idea to check your blood sugar anytime you're getting behind the wheel. If it's below 70 mg/dL (3.9 mmol/L), have a snack with 15 grams of carbohydrates. Retest again in 15 minutes to make sure it has risen to a safe level.
- Working. Type 1 diabetes can pose some challenges in the workplace. For example, if you work in a job that involves driving or operating heavy machinery, hypoglycemia could pose a serious risk to you and those around you. You may need to work with your doctor and your employer to ensure that certain accommodations are made, such as additional breaks for blood sugar testing and fast access to food and drink. There are federal and state laws in place that require employers to make reasonable accommodations for people with diabetes.
Being pregnant. Because the risk of pregnancy complications is higher for women with type 1 diabetes, experts recommend that women have a preconception evaluation and that A1C readings ideally should be less than 6.5 percent before they attempt to get pregnant.
The risk of birth defects is increased for women with type 1 diabetes, particularly when diabetes is poorly controlled during the first six to eight weeks of pregnancy. Careful management of your diabetes during pregnancy can decrease your risk of complications.
- Being older. For those who are frail or sick or have cognitive deficits, tight control of blood sugar may not be practical and could increase the risk of hypoglycemia. For many people with type 1 diabetes, a less stringent A1C goal of less than 8 percent may be appropriate.
Potential future treatments
- Pancreas transplant. With a successful pancreas transplant, you would no longer need insulin. But pancreas transplants aren't always successful — and the procedure poses serious risks. Because these risks can be more dangerous than the diabetes itself, pancreas transplants are generally reserved for those with very difficult-to-manage diabetes, or for people who also need a kidney transplant.
- Islet cell transplantation. Researchers are experimenting with islet cell transplantation, which provides new insulin-producing cells from a donor pancreas. Although this experimental procedure had some problems in the past, new techniques and better drugs to prevent islet cell rejection may improve its future chances of becoming a successful treatment.
Signs of trouble
Despite your best efforts, sometimes problems will arise. Certain short-term complications of type 1 diabetes, such as hypoglycemia, require immediate care.
Low blood sugar (hypoglycemia). This occurs when your blood sugar level drops below your target range. Ask your doctor what's considered a low blood sugar level for you. Blood sugar levels can drop for many reasons, including skipping a meal, eating fewer carbohydrates than called for in your meal plan, getting more physical activity than normal or injecting too much insulin.
Learn the symptoms of hypoglycemia, and test your blood sugar if you think your levels are dropping. When in doubt, always test your blood sugar. Early signs and symptoms of low blood sugar include:
- Dizziness or lightheadedness
- Rapid or irregular heart rate
- Blurred vision
Later signs and symptoms of low blood sugar, which can sometimes be mistaken for alcohol intoxication in teens and adults, include:
- Behavior changes, sometimes dramatic
- Poor coordination
Nighttime hypoglycemia may cause you to wake with sweat-soaked pajamas or a headache. Due to a natural rebound effect, nighttime hypoglycemia sometimes might cause an unusually high blood sugar reading first thing in the morning, also known as Somogyi effect.
If you have a low blood sugar reading:
- Have 15 to 20 grams of a fast-acting carbohydrate, such as fruit juice, glucose tablets, hard candy, regular (not diet) soda or another source of sugar. Avoid foods with added fat, which don't raise blood sugar as quickly because fat slows sugar absorption.
- Retest your blood sugar in about 15 minutes to make sure it's normal.
- If it's still low, have another 15 to 20 grams of carbohydrate and retest in another 15 minutes.
- Repeat until you get a normal reading.
- Eat a mixed food source, such as peanut butter and crackers, to help stabilize your blood sugar.
If a blood glucose meter isn't readily available, treat for low blood sugar anyway if you have symptoms of hypoglycemia, and then test as soon as possible.
Left untreated, low blood sugar will cause you to lose consciousness. If this occurs, you may need an emergency injection of glucagon — a hormone that stimulates the release of sugar into the blood. Be sure you always have an unexpired glucagon emergency kit available at home, at work and when you're out. Make sure that co-workers, family and friends know how to use the kit in case you are unable to give yourself the injection.
Hypoglycemia unawareness. Some people may lose the ability to sense that their blood sugar levels are getting low, called hypoglycemia unawareness. The body no longer reacts to a low blood sugar level with symptoms such as lightheadedness or headaches. The more you experience low blood sugar, the more likely you are to develop hypoglycemia unawareness. If you can avoid having a hypoglycemic episode for several weeks, you may start to become more aware of impending lows. Sometimes increasing the blood sugar target (for example, from 80 to 120 mg/DL to 100 to 140 mg/DL) at least temporarily can also help improve hypoglycemia awareness.
High blood sugar (hyperglycemia). Your blood sugar can rise for many reasons, including eating too much, eating the wrong types of foods, not taking enough insulin or fighting an illness.
- Frequent urination
- Increased thirst
- Blurred vision
- Difficulty concentrating
If you suspect hyperglycemia, check your blood sugar. If your blood sugar is higher than your target range, you'll likely need to administer a "correction" — an additional dose of insulin that should bring your blood sugar back to normal. High blood sugar levels don't come down as quickly as they go up. Ask your doctor how long to wait until you recheck. If you use an insulin pump, random high blood sugar readings may mean you need to change the pump site.
If you have a blood sugar reading above 240 mg/dL (13.3 mmol/L), test for ketones using a urine test stick. Don't exercise if your blood sugar level is above 240 mg/dL or if ketones are present. If only a trace or small amounts of ketones are present, drink extra fluids to flush out the ketones.
If your blood sugar is persistently above 300 mg/dL (16.7 mmol/L), or if your urine ketones remain high despite taking appropriate correction doses of insulin, call your doctor or seek emergency care.
Increased ketones in your urine (diabetic ketoacidosis). If your cells are starved for energy, your body may begin to break down fat — producing toxic acids known as ketones. Diabetic ketoacidosis is a life-threatening emergency.
Signs and symptoms of this serious condition include:
- Abdominal pain
- A sweet, fruity smell on your breath
- Weight loss
If you suspect ketoacidosis, check your urine for excess ketones with an over-the-counter ketones test kit. If you have large amounts of ketones in your urine, call your doctor right away or seek emergency care. Also, call your doctor if you have vomited more than once and you have ketones in your urine.
An insulin pump is a device about the size of a cellphone that's 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. Insulin pumps are programmed to dispense specific amounts of insulin automatically and when you eat.
Lifestyle and home remedies
Careful management of type 1 diabetes can reduce your risk of serious — even life-threatening — complications. Consider these tips:
- Make a commitment to manage your diabetes. Take your medications as recommended. Learn all you can about type 1 diabetes. Make healthy eating and physical activity part of your daily routine. Establish a relationship with a diabetes educator, and ask your health care team for help.
- Identify yourself. Wear a tag or bracelet that says you have diabetes. Keep a glucagon kit nearby in case of a low blood sugar emergency — and make sure your friends and loved ones know how to use it.
- Schedule a yearly physical exam and regular eye exams. Your regular diabetes checkups aren't meant to replace yearly physicals or routine eye exams. During the physical, your doctor will look for any diabetes-related complications, as well as screen for other medical problems. Your eye care specialist will check for signs of retinal damage, cataracts and glaucoma.
Keep your vaccinations up to date. High blood sugar can weaken your immune system. Get a flu shot every year. Your doctor will likely recommend the pneumonia vaccine, as well.
The Centers for Disease Control and Prevention (CDC) 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 CDC advises vaccination as soon as possible after diagnosis with type 1 or type 2 diabetes. If you are age 60 or older and have diabetes and haven't previously received the vaccine, talk to your doctor about whether it's right for you.
- Pay attention to your feet. Wash your feet daily in lukewarm water. Dry them gently, especially between the toes. Moisturize your feet with lotion. Check your feet every day for blisters, cuts, sores, redness or swelling. Consult your doctor if you have a sore or other foot problem that doesn't heal.
- Keep your blood pressure and cholesterol under control. Eating healthy foods and exercising regularly can go a long way toward controlling high blood pressure and cholesterol. Medication may be needed, too.
- If you smoke or use other forms of tobacco, ask your doctor to help you quit. Smoking increases your risk of diabetes complications, including heart attack, stroke, nerve damage and kidney disease. Talk to your doctor about ways to stop smoking or to stop using other types of tobacco.
- 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 and always with a meal. Check your blood sugar levels before going to sleep.
- Take stress seriously. The hormones your body may produce in response to prolonged stress may prevent insulin from working properly, which can stress and frustrate you even more. Take a step back, and set some limits. Prioritize your tasks. Learn relaxation techniques. Get plenty of sleep.
Coping and support
Diabetes can affect your emotions both directly and indirectly. Poorly controlled blood sugar can directly affect your emotions by causing behavior changes, such as irritability. There may be times you feel resentful about your diabetes.
People with diabetes have an increased risk of depression and diabetes-related distress, which may be why many diabetes specialists regularly include a social worker or psychologist as part of their diabetes care team.
You may find that talking to other people with type 1 diabetes is helpful. Support groups are available both online and in person. Group members often know about the latest treatments and tend to share their own experiences or helpful information, such as where to find carbohydrate counts for your favorite takeout restaurant.
If you're interested in a support group, your doctor may be able to recommend one in your area. Or you can visit the websites of the American Diabetes Association (ADA) or the Juvenile Diabetes Research Foundation (JDRF) for support group information and to check out local activities for people with type 1 diabetes. You can also reach the ADA at 800-DIABETES (800-342-2383) or JDRF at 800-533-CURE (800-533-2873).
Preparing for an appointment
If you suspect that you or your child might have type 1 diabetes, get evaluated immediately. A simple blood test can let your doctor know if you need further evaluation and treatment.
After diagnosis, you'll need close medical follow-up until your blood sugar level stabilizes. A doctor who specializes in hormonal disorders (endocrinologist) generally coordinates diabetes care. Your health care team will likely include:
- Certified diabetes educator
- Social worker or mental health professional
- Certified diabetes educator
- Doctor who specializes in eye care (ophthalmologist)
- Doctor who specializes in foot health (podiatrist)
Once you've learned the basics of managing type 1 diabetes, your endocrinologist likely will recommend checkups every few months. A thorough yearly exam and regular foot and eye exams also are important — especially if you're having a hard time managing your diabetes, if you have high blood pressure or kidney disease, or if you're pregnant.
These tips can help you prepare for your appointments and know what to expect from your doctor.
What you can do
- Write down any questions you have as they occur. Once you begin insulin treatment, the initial symptoms of diabetes should go away. However, you may have new issues that you need to address, such as recurring low blood sugar episodes or how to address high blood sugar after eating certain foods.
- Write down key personal information, including any major stresses or recent life changes. Many factors can affect your diabetes control, including stress.
- Make a list of all medications, vitamins and supplements you're taking.
- For your regular checkups, bring a book with your recorded glucose values or your meter to your appointments.
- Write down questions to ask your doctor.
Preparing a list of questions can help you make the most of your time with your doctor and the rest of your health care team. For type 1 diabetes, topics you want to clarify with your doctor, dietitian or diabetes educator include:
- The frequency and timing of blood glucose monitoring
- Insulin therapy — types of insulin used, timing of dosing, amount of dose
- Insulin administration — shots versus a pump
- Low blood sugar — how to recognize and treat
- High blood sugar — how to recognize and treat
- Ketones — testing and treatment
- Nutrition — types of food and their effect on blood sugar
- Carbohydrate counting
- Exercise — adjusting insulin and food intake for activity
- Medical management — how often to visit the doctor and other diabetes care specialists
- Sick day management
What to expect from your doctor
Questions your doctor is likely to ask include:
- How comfortable are you managing your diabetes?
- How frequent are your low blood sugar episodes?
- Are you aware of when your blood sugar is getting low?
- What's a typical day's diet like?
- Are you exercising? If so, how often?
- On average, how much insulin are you using daily?
What you can do in the meantime
If you're having trouble managing your blood sugar or you have questions, don't hesitate to contact your health care team in between appointments.
