The Three Main Types of Diabetes

There are three main types of diabetes: Type 1 diabetes, Type 2 diabetes, and gestational diabetes.

Type 1 Diabetes

Type 1 diabetes is usually diagnosed in young people. It can occur at any age, however.  People with Type 1 diabetes produce no insulin.

Symptoms of Type 1 Diabetes Include:

Type 2 Diabetes

Type 2 diabetes is the most common form of diabetes. People can develop Type 2 diabetes at any age. With Type 2 diabetes, the receptors on the cells become resistant to insulin’s action.  Sometimes a person does not make enough insulin. This also is Type 2 diabetes. Being overweight and inactive increases the risk for Type 2 diabetes.

Not everyone who is obese or overweight will develop diabetes. Genetics, diet, and physical activity all play an important role in how well insulin and glucose interact.

Symptoms of Type 2 Diabetes Include:

  • Frequent urination (polyuria)
  • Thirst (polydipsia)
  • Blurred vision
  • Weight gain, weight loss or no change
  • Being tired
  • Many people have no noticeable symptoms

Gestational Diabetes

Gestational diabetes is a form of diabetes that occurs during pregnancy. When a woman becomes pregnant, there are many hormonal changes. These changes, especially in the later stages of pregnancy, can affect the mother’s sensitivity to insulin. Doctors often check women’s blood glucose levels during their pregnancy. High blood glucose levels can cause complications during the pregnancy or after the baby is born.
