Type 1 diabetes is also known as insulin-dependent diabetes mellitus. It is the most common type of diabetes found in children and young adults. When a child has Type 1 diabetes, his pancreas can no longer make insulin. The immune system gets confused, and attacks and kills the pancreas cells that make insulin, rather than recognizing them as a normal part of the body.

About 1 in 7 people with Type 1 diabetes have a family member who also has Type 1 diabetes. Children who have Type 1 diabetes can stay healthy by taking insulin injections every day. They can become very sick and even die if they cannot get insulin.

Type 2 diabetes is sometimes called non-insulin-dependent diabetes mellitus. And until recently, it has mainly affected only adults. Today, however, Type 2 diabetes is becoming more common in children. Most kids with Type 2 diabetes have a family member with Type 2 diabetes. Unlike Type 1 diabetes, the immune system has nothing to do with Type 2 diabetes.

Type 2 diabetes means your child’s body has a resistance to insulin, and his body doesn’t use insulin in the right way. Even though many children take medication or insulin injections to treat Type 2 diabetes, the most important part of treatment is to eat right and be active.

Cystic fibrosis is an inherited disease that affects the lungs and also causes pancreas problems. If the pancreas does not make enough insulin, diabetes may develop. Your child’s body may develop a resistance to insulin, which means it doesn't use insulin in the right way. Even though cystic fibrosis-related diabetes does not always cause symptoms, it usually needs to be treated with insulin injections.

Some medications, such as steroids, can temporarily raise blood glucose levels. People with diabetes will almost always need to change their diabetes treatment when they take steroid medications.

Diabetes insipidus occurs when a hormone that controls urine production cannot be made or cannot work in the kidneys. The hormone is called anti-diuretic hormone and is made in the pituitary gland. Diabetes insipidus can cause many symptoms of other forms of diabetes, but blood sugar levels are normal, and the pancreas is not involved.

A woman is diagnosed with this type of diabetes when her blood glucose is too high during pregnancy. This can cause complications for the baby, including the baby being bigger than usual at birth, weighing more than 10 pounds at times.

Mothers who have gestational diabetes are at a high risk for getting Type 2 diabetes later in life. Children who are born to a mother with gestational diabetes are also at higher risk for being overweight and getting Type 2 diabetes when they are adults.

The immune system of children with Type 1 diabetes sometimes attacks other organs besides the pancreas. Immune cell reactions against the thyroid gland are the most common, and they can cause the gland to become overactive or underactive. The thyroid is a butterfly-shaped organ in the neck that controls the speed of everything in your body. When a child’s thyroid hormone is too low, things move too slowly. When it is too high, things move too quickly.

Celiac disease causes the intestines to react against proteins in grains, including wheat, rye and barley. Children with Type 1 diabetes are at high risk for having celiac disease. Symptoms can be severe, including slow growth and diarrhea. Some children with celiac disease do not know they have symptoms until after they are treated and realize how much better they feel.

Cholesterol and triglycerides are types of fat that travel in the blood to all the cells of the body. Children with Type 1 and Type 2 diabetes are at risk of having high levels of cholesterol and triglycerides. If these levels are high for many years, they can raise the risk of heart attack or stroke. Usually, the only way to know if cholesterol and triglycerides are too high is to do a blood test. Some children need to take medication to keep their levels safe.

Some children and families have a hard time coping after a diabetes diagnosis. Counseling and other steps can help. Talk to your doctor about options to get support.
