When it comes to your body, you probably spend more time thinking about your hair
than your hormones. For some people, though, a problem with a hormone
called insulin causes a health condition called type 2 diabetes (pronounced:
What Is Diabetes?
Diabetes is a disease that affects how the body uses glucose
(pronounced: GLOO-kose), a sugar that is the body's main source of fuel. Your body
needs glucose to keep running. Here's how it should work:
Glucose from the food gets into your bloodstream.
Your pancreas makes a hormone called insulin
Insulin helps the glucose get into the body's cells.
Your body gets the energy it needs.
The pancreas is a long, flat
gland in your belly that helps your body digest food. It also makes insulin. Insulin
is like a key that opens the doors to the cells of the body. It lets the glucose in.
Then the glucose can move out of the blood and into the cells.
But if someone has diabetes, either the body can't make insulin or the insulin
doesn't work in the body like it should. The glucose can't get into the cells normally,
so the blood sugar level
gets too high. Lots of sugar in the blood makes people sick if they don't get treatment.
What Is Type 2 Diabetes?
There are two major types of diabetes: type 1 and type 2. Each type causes high
blood sugar levels in a different way.
In type 1 diabetes, the pancreas
can't make insulin. The body can still get glucose from food, but the glucose can't
get into the cells, where it's needed, and glucose stays in the blood. This makes
the blood sugar level very high.
With type 2 diabetes, the body still makes insulin. But a person with type 2 diabetes
doesn't respond normally to the insulin the body makes. So glucose is less able to
enter the cells and do its job of supplying energy.
When glucose can't enter the cells in this way, doctors call it insulin
resistance. Although there's plenty of insulin in the person's body, because it
doesn't work properly, the pancreas still detects high blood sugar levels. This makes
the pancreas produce even more insulin.
The pancreas may eventually wear out from working overtime to produce extra insulin.
When this happens, it may no longer be able to produce enough insulin to keep blood
sugar levels where they should be. In general, when someone's blood sugar levels are
repeatedly high, it's a sign that he or she has diabetes.
Who Gets Type 2 Diabetes?
What makes people more likely to develop type 2 diabetes? No one knows for sure.
But experts have a few ideas about what puts a person at greater risk:
Most people who have type 2 diabetes are overweight.
People with family members who have diabetes get diabetes more often.
People who are older than 10 are more likely to develop type 2 diabetes than younger
What Are the Signs & Symptoms of Type 2 Diabetes?
People who have type 2 diabetes may not know it because the symptoms aren't always
obvious and they can take a long time to develop. Some people don't have any symptoms
But when a person gets type 2 diabetes, he or she may:
pee a lot because the body tries to get rid of the extra blood
sugar by passing it out of the body in the urine
drink a lot to make up for all that peeing
feel tired all the time because the body can't use sugar for
Also, people whose bodies are having problems using insulin or who are overweight
may notice something called acanthosis
nigricans. This can cause a dark ring around the neck that doesn't wash off, as
well as thick, dark, velvety skin under the arms, in between fingers and toes, between
the legs, or on elbows and knees. This skin darkening can lighten over time with improvement
in insulin resistance.
In addition, girls with insulin resistance may have polycystic
ovary syndrome (PCOS). In PCOS, the ovaries get bigger and develop fluid-filled
sacs called cysts. Girls with this condition often have irregular periods or may stop
having periods, and they might have excess facial and body hair.
How Is Type 2 Diabetes Diagnosed?
Doctors can say for sure if a person has diabetes by testing blood samples for
glucose. Even if someone doesn't have any symptoms of type 2 diabetes, doctors may
order blood tests to check
for it if the person has certain risk factors (for instance, being overweight).
Some kids and teens with diabetes may go to a pediatric
endocrinologist — a doctor who specializes in diagnosing and treating children
and teens living with diseases of the endocrine
system, such as diabetes and growth problems.
How Is Type 2 Diabetes Treated?
Sometimes people with type 2 diabetes take pills that help the insulin in their
bodies work better. Some also need insulin
shots or an insulin pump
to control their diabetes.
People with type 2 diabetes have to pay a little more attention to what they're
eating and doing than people who don't have diabetes. They may need to:
Eat a healthy diet, as determined by the care team.
Get regular physical activity to achieve a healthy weight and allow insulin to
work more effectively.
Check their blood sugar levels on a regular basis.
Get treatment for other health problems that can happen more often in people with
type 2 diabetes, like high blood
pressure or problems with the levels of fats in their blood.
Have regular checkups with doctors and other people on their diabetes health care
team so they can stay healthy and get treatment for any diabetes problems.
People with type 2 diabetes might have to eat smaller food portions and less salt
or fat, too. Those who eat healthy foods, stay active, and get to a healthy weight
may bring their blood sugar levels into a healthier range. Their doctors may even
say they don't need to take any medicines at all.
What's it Like for Teens With Type 2 Diabetes?
Sometimes people who have diabetes feel different from their friends because they
need to think about how they eat and how to control their blood sugar levels every
Some teens with diabetes want to deny that they even have it. They might hope that
if they ignore diabetes, it will just go away. They may feel angry, depressed,
or helpless, or think that their parents are constantly worrying about their diabetes
If you've been diagnosed with type 2 diabetes, it's normal to feel like your world
has been turned upside down. Your diabetes care team is there to provide answers and
support. Don't hesitate to ask your doctors, dietitian, and other treatment professionals
for advice and tips. It also can help to find support groups where you can talk about
your feelings and find out how other teens cope.
Diabetes brings challenges, but teens who have it play sports, travel, date, go
to school, and work just like their friends.
