Type 1 Diabetes (People with Type 1 diabetes are insulin dependent and only account for 5 to 10% of all people with diabetes.)

Type 1 diabetes is when the auto-immune system causes the destruction of insulin producing cells (beta cells) in the pancreas. Scientific research has not yet found why this body self-destruction occurs. Type 1 diabetes is usually diagnosed under the age of 30. Its incidence rate is highest in ages 12-14, but it can happen at any age. You did not do anything to get the disease and it is not contagious.

A person developing Type 1 diabetes will usually experience a sudden onset of classic diabetes symptoms:

  • Frequent thirst (polydypsia)
  • Frequent urination (polyuria)
  • Excessive hunger (polyphagia)
  • Unexpected weight loss
  • Fatigue
  • Fruity smelling breath

These may lead to nausea, vomiting, and a serious and life threatening condition called ketoacidosis.

Although research points to hereditary factors being involved with developing this type of diabetes, frequently there is no known family history.

Type 2 Diabetes (around 90% of all people with diabetes )

Alarming new data from the Centers for Disease Control and Prevention's diabetes division shows that in the past 8 years the rate of diabetes has jumped 70% among people in their 30s.

A one-third jump in the rate of any disease in just eight years is unheard of and represents a national crisis. Because diabetes tends to be a silent disease, this disturbing trend hasn't gotten the attention it should.

The experts state the factors leading to this incredible increase in diabetes among such a young group could possibly be:

  • a national problem with obesity
  • lack of exercise
  • stressful jobs and schedules that lead to improper eating - eating too much fast food or fatty food.

Type 2 diabetes occurs in people who for a variety of reasons have experienced:

  • decreased insulin sensitivity or
  • decreased insulin production
  • or both of the above

With Type 2, a family history is usually present and African Americans, Hispanic, Pacific Islanders and Native Americans are at greatest risk.

Frequently with Type 2 diabetes symptoms don't occur for years even if you have the disease and certain factors put some people at more risk:

Risk Factors for Type 2 Diabetes:

  • Increased weight
  • Family history of diabetes
  • History of gestational diabetes or of a having a baby over 9 pounds at birth
  • High blood pressure
  • High risk populations (see above)
  • Increased age

People with Type 2 Diabetes are treated with diet, oral medications and/or insulin.

Gestational Diabetes (About 2 to 5 % of all pregnant women develop gestational diabetes.)

Gestational diabetes is a special type of diabetes that develops during a pregnancy and usually disappears after the baby is born. These women are at a high risk for developing Type 2 diabetes later in life.

Risks for gestational diabetes include:

  • increased weight
  • family history of diabetes
  • high risk ethnic group - African American, Hispanic, Pacific Islander and Native American
  • having had a previous child that weighed over 9 lbs. at birth
  • increased age at time of pregnancy

The Mercy Diabetes Team works closely with Mercy's Department of Obstetrics and Gynecology to provide resources for mothers-to-be with gestational diabetes.

Other causes of Diabetes (this amounts for only a very small percentage of all diabetes)

  • Diabetes can also be caused by traumas ( for example - an auto accident severely injuring the pancreas)
  • Cancer necessitating the removal of the pancreas
  • Certain medications such as steroids and chemotherapy medications
  • Other endocrine diseases
  • Many other obscure causes.
