Treatment for type 1 diabetes includes:
fat and protein counting
blood sugar monitoring
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:
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
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:
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
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
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:
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
Certain life circumstances call for different
- 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
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.
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
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.
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:
or irregular heart rate
Later signs and symptoms of low blood sugar, which can
sometimes be mistaken for alcohol intoxication in teens and adults, include:
changes, sometimes dramatic
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:
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.
your blood sugar in about 15 minutes to make sure it's normal.
it's still low, have another 15 to 20 grams of carbohydrate and retest in
another 15 minutes.
until you get a normal reading.
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.
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
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
Signs and symptoms of this serious condition include:
sweet, fruity smell on your breath
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.
