The animations below depict how diabetes affects a person’s bloodstream; the animations compare the bloodstreams of a person with Type 1 diabetes, Type 2 diabetes, and a healthy body.

What is Type 1 diabetes?

  • In Type 1 diabetes, the body is unable to produce enough insulin, a hormone produced by cells in the pancreas. Insulin is needed to move blood sugar (glucose) into cells for energy use.
  • Glucose is necessary to provide a person’s body with energy.
  • This inability to move blood sugar into cells results in a high build-up of glucose in the bloodstream called hyperglycemia.
  • Normal blood sugar levels range from about 70 to 140 mg/dL (milligrams per deciliter).
  • However, a diabetic person can experience either a drop or rise in blood sugar beyond healthy levels, which can affect mental and physical functions.
  • Type 1 diabetes is thought to be an autoimmune disease where the body mistakenly attacks the pancreatic cells that make insulin.
  • Formerly known as juvenile diabetes, Type 1 diabetes is most often diagnosed in children and young adults. It can be passed down in families.
  • Type 1 diabetes develops quickly (in weeks and even days) as the pancreas stops producing insulin.
  • It can be treated with insulin injections and a healthy diet and lifestyle.

What is Type 2 diabetes?

  • Type 2 diabetes, or adult-onset diabetes, is the most common form of diabetes; around 90 percent of diabetics are diagnosed with this type.
  • It tends to occur in overweight or obese adults, who live an unhealthy lifestyle.
  • It is often diagnosed at mid age.
  • In Type 2 diabetes, the body either does not produce enough insulin or the body’s cells become insulin resistant, meaning the cells ignore the insulin the body produces.
  • Some people can be genetically predisposed to developing Type 2 diabetes.
  • It is more common in certain ethnic groups such as those of African, Native American, Hispanic, and Pacific Island decent.

What happens in Type 2 diabetes?

Although people with Type 2 diabetes can produce insulin (unlike those with Type 1 diabetes), their muscle and fat cells are unable to use it properly. This often occurs in the obese because excess fat prevents a person’s body from properly using insulin. Additionally, the pancreas has difficulty producing more insulin to counter the insulin resistance. Because people with Type 2 diabetes still produce insulin, the disease and its symptoms tend to develop gradually, unlike in Type 1 diabetes. Many overweight individuals are unaware that they are at risk of developing or have already developed the disease.

This is how a healthy person’s bloodstream should function:
