Type 2 Diabetes
Type 1 and type 2 diabetes cause high blood sugar levels in different ways.
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. Glucose stays in the blood. This makes the blood sugar level very high.
Type 2 diabetes is different. With type 2, the pancreas still makes insulin. But the insulin doesn't do its job as well in the body. Glucose just hangs around and builds up in the blood. The pancreas makes even more insulin to get glucose to go into the cells, but eventually gets worn out from working so hard. As a result, the blood sugar levels rise too high.
Most people who have type 2 diabetes are overweight. In the past, mainly overweight adults got type 2 diabetes. Today, more kids are being diagnosed with type 2 diabetes, probably because more kids are overweight.
Experts think that the tendency to get it is probably passed down through families. Kids with family members who have type 2 diabetes get diabetes more often. Also, kids from Native American, African American, Hispanic/Latino, or Asian/Pacific Island backgrounds are also more likely to get type 2 diabetes. Kids older than 10 are more likely to get type 2 diabetes than younger kids.
How Do People Know if They Have Type 2 Diabetes?
Some kids can have type 2 diabetes without knowing it. Some of the signs aren't easy to spot and can take a long time to develop. And a lot of kids don't have any symptoms at all.
But when a person first gets type 2 diabetes, he or she usually:
- feels tired a lot because the body can't use sugar for energy properly
- pees a lot because the body tries to get rid of the extra blood sugar by passing it out of the body in the urine (pee)
- drinks a lot to make up for all that peeing
The skin can look different in some kids with type 2 diabetes. They may notice a dark ring around their necks that doesn't wash off. They may also see thick, dark, velvety skin under the arms, between the legs, between fingers and toes, or on elbows and knees.
How do you find out whether you have diabetes? Doctors can say for sure if a person has diabetes by testing blood samples for glucose. Even if a kid doesn't have any symptoms of type 2 diabetes, doctors may use blood tests to check for it in kids who are more likely to get it — like those who are overweight.
If you have type 2 diabetes, you may visit a doctor called a pediatric endocrinologist (say: pee-dee-ah-trik en-doh-krih-nah-leh-jist). A pediatric endocrinologist helps kids with diabetes, growth problems, and more.
