Type 1 diabetes in children is a condition in which your child’s body no longer produces an important hormone (insulin).

Type 1 diabetes in children and Parental Responsibility

Your child needs insulin to survive, so the missing insulin needs to be replaced with injections or with an insulin pump.

Type 1 diabetes in children used to be known as juvenile diabetes or insulin-dependent diabetes.

The diagnosis of type 1 diabetes in children can be overwhelming, especially in the beginning. Suddenly you and your child — depending on his or her age — must learn how to give injections, count carbohydrates and monitor blood sugar.

There’s no cure for type 1 diabetes in children, but it can be managed. Advances in blood sugar monitoring and insulin delivery have improved blood sugar management and quality of life for children with type 1 diabetes.


The signs and symptoms of type 1 diabetes in children usually develop quickly, and may include:

  • Increased thirst
  • Frequent urination, possibly bed-wetting in a toilet-trained child
  • Extreme hunger
  • Unintentional weight loss
  • Fatigue
  • Irritability or behavior changes
  • Fruity-smelling breath

When to see a doctor

See your child’s doctor if you notice any of the signs or symptoms of Type 1 diabetes in children.


The exact cause of type 1 diabetes is unknown. But in most people with type 1 diabetes, the body’s immune system — which normally fights harmful bacteria and viruses — mistakenly destroys insulin-producing (islet) cells in the pancreas. Genetics and environmental factors appear to play a role in this process.

Once the islet cells of the pancreas are destroyed, your child produces little or no insulin. Insulin performs the critical job of moving sugar (glucose) from the bloodstream to the body’s cells. Sugar enters the bloodstream when food is digested.

Without enough insulin, sugar builds up in your child’s bloodstream, where it can cause life-threatening complications if left untreated.

Risk factors

Risk factors for type 1 diabetes in children include:

  • Family history. Anyone with a parent or siblings with type 1 diabetes has a slightly increased risk of developing the condition.
  • Certain genes indicate an increased risk of type 1 diabetes.
  • In the United States, type 1 diabetes is more common among white children of non-Hispanic descent than among children of other races.
  • Certain viruses. Exposure to various viruses may trigger the autoimmune destruction of the islet cells.


Type 1 diabetes can affect the major organs in your body. Keeping your blood sugar level close to normal most of the time can dramatically reduce the risk of many complications.

Complications can include:

  • Heart and blood vessel disease. Diabetes increases your child’s risk of developing conditions such as narrowed blood vessels, high blood pressure, heart disease and stroke later in life.
  • Nerve damage. Excess sugar can injure the walls of the tiny blood vessels that nourish your child’s nerves. This can cause tingling, numbness, burning or pain. Nerve damage usually happens gradually over a long period of time.
  • Kidney damage. Diabetes can damage the numerous tiny blood vessel clusters that filter waste from your child’s blood.
  • Eye damage. Diabetes can damage the blood vessels of the retina, which may lead to vision problems.
  • Diabetes may lead to lower than normal bone mineral density, increasing your child’s risk of osteoporosis as an adult.


There’s currently no known way to prevent type 1 diabetes, but this is a very active area of research. Researchers are working on:

  • Preventing type 1 diabetes in people who have a high risk of the disease, and recently identified at least one drug that may slow down the development of the condition.
  • Preventing further destruction of the islet cells in people who are newly diagnosed.

Doctors can detect the antibodies associated with type 1 diabetes in children who have a high risk of the disorder. These antibodies can be detected months or even years before the first symptoms of type 1 diabetes appear, but there’s currently no known way to slow or prevent the disease when antibodies are found. It’s also important to know that not everyone with these antibodies goes on to develop type 1 diabetes.

While there’s nothing you could have done to prevent your child’s type 1 diabetes, you can help your child prevent its complications by:

  • Helping your child maintain good blood sugar control as much as possible
  • Teaching your child the importance of eating a healthy diet and participating in regular physical activity

Scheduling regular visits with your child’s diabetes doctor and a yearly eye exam beginning no more than five years after the initial diabetes diagnosis or by age 10.
