Type 2 Diabetes in ChildrenEn Español (Spanish Version)
Glucose is a type of sugar. Under normal conditions, rising glucose levels in the blood cause the pancreas to produce a hormone known as insulin. Insulin allows the glucose in the blood to enter the cells of the body and be converted into energy. Type 2 diabetes
develops when the body loses its ability to respond properly to insulin.
In type 2 diabetes, the body’s cells become less sensitive to insulin. As a result, large amounts are required for glucose control. Unfortunately, the pancreas cannot maintain this high level of insulin production indefinitely, and eventually the body loses the ability to produce all the insulin it needs. At this point, blood sugar levels rise. Despite these high blood sugar levels, symptoms of diabetes may either be absent or mild.
type 1 diabetes
occurs only after the pancreas is severely damaged by the body’s immune system. The damaged pancreas can no longer produce enough insulin. Instead of the high levels of insulin and insulin resistance seen in type 2 diabetes, very low levels of insulin occur in type 1 diabetes. As a result, sudden serious illness requiring emergency insulin treatment is common in type 1 diabetes.
is the major cause of most type 2 diabetes. The tissue of overweight people often becomes resistant to insulin. Since physical activity improves tissue sensitivity to insulin, physically inactive people may also have tissues that are more insulin resistant.
The short-term effects of type 2 diabetes include:
- Frequent urination
- Increased thirst
Possible long-term effects of type 2 diabetes include:
- Eye disease and vision problems
- Kidney disease
Heart disease and circulatory problems,
Nerve damage, neuropathy
- Problems with wound healing
- Reduced life expectancy
According to the American Diabetes Association (ADA), doctors should begin to screen children for diabetes at age 10 or puberty if they are overweight and have at least two other risk factors for diabetes. Screening should be repeated every 3 years. In addition to obesity, other risk factors for type 2 diabetes include:
- Family history: a close relative with type 2 diabetes, including mothers having diabetes or gestational diabetes
- Other conditions associated with insulin resistance, such as:
The risk of type 2 diabetes is higher in children of African American, Asian American, Native American, and Pacific Islander descent.
A blood test is done for screening and diagnosis. The most commonly used test is the fasting plasma glucose, a blood test done after a person has fasted for eight hours. A fasting plasma glucose (blood sugar) level of 126 milligrams per deciliter or greater on two separate occasions is diagnostic of diabetes. Other tests, like a hemoglobin A1c (HbA1c)
test or a two-hour glucose tolerance test, can also be done to diagnose diabetes.
Managing blood sugar levels requires major lifestyle changes for children. To succeed, children need adult supervision and support. The entire family should work with a diabetes team (doctor, nurse, social worker, dietitian, and exercise counselor) to develop a healthy lifestyle.
Children living with type 2 diabetes need daily strategies to maintain normal blood sugar levels. These include:
Planning healthy meals
- Eliminate regular sodas, limit carbohydrates and sugar-sweetened fruit juice, and have your child eat whole grains and vegetables.
- Count grams of carbohydrates and read food labels.
Increasing physical activity
- Encourage your child to get plenty of active play time every day.
- Plan for periods of low blood sugar caused by activity. Carry short-acting glucose or carbohydrates.
Monitoring and taking medications
- Check your child's blood sugar levels throughout the day if directed. There are different ways to check blood sugar levels. Some methods involve pricking the finger or arm and applying a drop of blood to a meter with a glucose-sensitive strip.
- Schedule regular eye and foot exams to detect and treat early vision and circulatory problems.
- Have your child's blood pressure and cholesterol levels monitored.
- To control blood sugar, have your child take medications and/or insulin injections as prescribed.
The primary preventive measures for type 2 diabetes are maintaining a healthy weight and getting regular exercise. A diet with age appropriate calorie intake and plenty of fruits and vegetables is ideal for diabetes prevention. Active daily play should also be encouraged in school and at home. Children should have fun exercising instead of spending a lot of time online, watching TV, or playing video games.
