Type 2 Diabetes In Children


Type 2 diabetes is a disease that affects how your child's body uses glucose (sugar). Normally, when the blood sugar level increases, the pancreas makes more insulin. Insulin helps move sugar out of the blood so it can be used for energy. Type 2 diabetes develops because either the body cannot make enough insulin, or it cannot use the insulin correctly. After many years, your child's pancreas may stop making insulin.


Return to the emergency department if:

  • Your child has a low blood sugar level and it does not improve with treatment.
  • Your child's blood sugar level is above 240 mg/dL and does not come down after a dose of insulin.
  • Your child has ketones.
  • Your child has a fever.
  • Your child has nausea or is vomiting and cannot keep any food or liquid down.
  • Your child has symptoms of a low blood sugar level, such as trouble thinking, sweating, or a pounding heartbeat.
  • Your child has blurred or double vision.
  • Your child's breath has a fruity, sweet smell, or his breathing is deep and labored.
  • Your child's heartbeat is fast and weak.

Contact your child's healthcare provider if:

  • Your child's blood sugar levels are higher than his or her target goals.
  • Your child often has low blood sugar levels.
  • Your child has abdominal pain, diarrhea, or is vomiting.
  • Your child has numbness in his or her arms or legs.
  • Your child has warm, red patches of skin or a wound that does not heal.
  • Your child gets easily irritated.
  • Your child is anxious or depressed.
  • You have questions or concerns about your child's condition or care.


  • Medicines , such as insulin or medicines by mouth, may be given to decrease the amount of sugar in your child's blood.
  • Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell him or her if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.

Check your child's blood sugar level as directed:

You will be taught how to check a small drop of blood with a glucose monitor. You may need to check your child's blood sugar level at least 3 times each day. Ask your child's healthcare provider when and how often to check during the day or night. Before meals , your child's blood sugar should be between 90 and 130 mg/dL. At bedtime , it should be between 90 and 150 mg/dL. You may need to check for ketones in your child's urine or blood if the level is higher than directed. Write down the results and show them to your child's healthcare provider. The provider may use the results to make changes to your child's medicine, food, or exercise schedules.

How to check your blood sugar

Medical alert identification:

Make sure your child always wears medical alert jewelry or carries a card that says he or she has diabetes. Ask your child's healthcare provider where to get these items.

Medical alert ID bracelet

Give directions to your child's school:

Make sure your child's teachers know he or she has diabetes. Provide written instructions about what to do if your child has symptoms of high or low blood sugar levels at school.

Help your child maintain a healthy weight:

Ask your child's healthcare provider how much your child should weigh. A healthy weight can help control your child's diabetes. Ask your child's healthcare provider to help you create a weight loss plan for your child if he or she is overweight. The provider can help your child set manageable weight loss goals.

Follow your child's meal plan:

A dietitian will help you create a meal plan to keep your child's blood sugar level steady. Do not let your child skip meals. His or her blood sugar level may drop too low if he or she takes insulin and does not eat.

  • Keep track of carbohydrates (sugar and starchy foods). Your child's blood sugar level can get too high if he or she eats too many carbohydrates. His or her dietitian will help you plan meals and snacks that have the right amount of carbohydrates.
  • Give your child low-fat and low-sodium foods. Examples of low-fat foods are lean meat, fish, skinless chicken or turkey, and low-fat milk. Limit high-sodium foods, such as potato chips and soup. Do not add salt to food you cook. Limit your child's use of table salt.
  • Give your child high-fiber foods. Foods that are a good source of fiber include vegetables, whole-grain breads, and beans.

Have your child exercise as directed:

Exercise can help keep your child's blood sugar level steady. Encourage your child to exercise for at least 60 minutes on most days of the week. Help your child include activities 3 days each week that strengthen his or her muscles and bones. Work with your child's healthcare provider to create an exercise plan.

  • Check your child's blood sugar level before and after exercise. Healthcare providers may tell you to change the amount of insulin your child takes or food he or she eats. If the blood sugar level is high, check your child's blood or urine for ketones before you exercise. Do not let your child exercise if the blood sugar level is high and your child has ketones.
  • If your child's blood sugar level is less than 100 mg/dL, have him or her eat a carbohydrate snack before exercise. Examples are 4 to 6 crackers, ½ banana, 8 ounces (1 cup) of milk, or 4 ounces (½ cup) of juice. Have your child drink water or liquids that do not contain sugar before, during, and after exercise. Ask your dietitian or healthcare provider which liquids your child should drink when he or she exercises.

Ask about vaccines:

Your child has a higher risk for serious illness if he or she gets the flu or pneumonia. Ask your child's healthcare provider if your child should get a flu or pneumonia vaccine, and when to get the vaccine.

Foot care:

Check your child's feet each day for sores. Have your child's feet checked at least once each year for problems that may develop if his or her diabetes is not controlled. Make sure his or her shoes and socks fit correctly. Ask your child's healthcare provider for more details about foot care.

Do not smoke around your child:

Do not let others smoke around him or her. Do not let your older child smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung and heart damage. Cigarette smoke can worsen the problems that occur with diabetes. Ask your healthcare provider for information if you or child currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you or your child use these products.

Follow up with your child's healthcare provider as directed:

Your child may need to return to have his or her A1c checked at least twice a year. He or she may also need tests to check his or her blood pressure, cholesterol, eyes, and feet.
