Type 1 diabetes accounts for 5 to 10 percent of diagnosed cases of diabetes.
The risk of developing type 1 diabetes is higher than virtually all other severe chronic diseases of childhood.
Peak incidence occurs during puberty, around 10 to 12 years of age in girls, and 12 to 14 years of age in boys.
The symptoms for type 1 diabetes can mimic the flu in children.

Type 1 diabetes may also be known by a variety of other names, including the following:
There are two forms of type 1 diabetes:
Immune-mediated diabetes is the most common form of type 1 diabetes, and the one generally referred to as type 1 diabetes. The information on this page refers to this form of type 1 diabetes.
Type 1 diabetes accounts for 5 to 10 percent of all diagnosed cases of diabetes in the U.S. Type 1 diabetes usually develops in children or young adults, but can start at any age.
The cause of type 1 diabetes is unknown, but it is believed that genetic and environmental factors (possibly viruses) may be involved. The body's immune system attacks and destroys the insulin producing cells in the pancreas. Insulin allows glucose to enter the cells of the body to provide energy.
When glucose cannot enter the cells, it builds up in the blood, depriving the cells of nutrition. People with type 1 diabetes must take daily insulin injections and regularly monitor their blood sugar levels.
Type 1 diabetes often appears suddenly. The following are the most common symptoms of type 1 diabetes. However, each individual may experience symptoms differently. Symptoms may include:
In children, symptoms may be similar to those of having the flu.
The symptoms of type 1 diabetes may resemble other conditions or medical problems. Always consult your doctor for a diagnosis.
The Diabetes Control and Complications Trial (DCCT), a landmark 10-year study, demonstrated that persons who lowered their blood glucose concentration have a better chance of delaying or preventing diabetes complications that affect the eyes (retinopathy), kidneys (nephropathy), and nerves (neuropathy).
Two groups of patients with type 1 diabetes were studied: one group followed a standard treatment regimen and the other group followed an intensive treatment regimen. Persons who lowered their blood glucose levels practiced the intensive treatment regimens which included careful self-monitoring of glucose, multiple daily insulin injections, and close doctor contact.
Type 1 diabetes may cause the following:
Complications that may result from type 1 diabetes include:
Specific treatment for type 1 diabetes will be determined by your doctor based on:
People with type 1 diabetes must have daily injections of insulin to keep their blood sugar level within normal ranges. Other parts of the treatment protocol may include:
Advances in diabetes research have led to improved methods of managing diabetes and treating its complications. However, scientists continue to explore the causes of diabetes and ways to prevent and treat the disorder. Other methods of administering insulin through inhalers and pills are currently being studied. Scientists are investigating gene involvement in type 1 and type 2 diabetes, and some genetic markers for type 1 diabetes have been identified. Pancreas and islet cell transplants are also being performed.
