- Type 1 diabetes accounts for approximately 5-10% of people with diabetes.
Type 1 diabetes is also known as juvenile or insulin dependent diabetes. It usually develops in children and young adults but can appear at any age. Type 1 diabetes is an autoimmune disease (when the body's system for fighting infection, otherwise known as the immune system, turns against a part of your body). With diabetes, your immune system attacks the insulin-producing beta cells in your pancreas. When that happens, your pancreas produces little to no insulin. A person who has type 1 diabetes must take a regular amount of insulin daily to live- either by injection or by insulin pump.
Science has yet to determine what causes the body's immune system to attack these beta cells. Research suggests many influences could be involved, some of which include: autoimmune, genetic, and environmental factors, possibly viruses.
Symptoms of type 1 diabetes usually develop without warning. Symptoms include increased thirst and urination, continuous hunger, sudden weight loss, blurry vision, and extreme fatigue. If not diagnosed and properly treated with insulin, a person with type 1 diabetes can lapse into what's called a diabetic ketoacidosis, also called a life-threatening diabetic coma.
- Type 2 diabetes accounts for approximately 90% of people diagnosed with diabetes.
Type 2 diabetes is known as adult on-set or noninsulin-dependent diabetes. About 80 percent of people with type 2 diabetes are considered overweight. This form of diabetes is associated with older age, obesity, a family history of diabetes, previous history of gestational diabetes, physical inactivity, and certain ethnicities.
Type 2 diabetes is increasingly being diagnosed in children and young adults, especially among African American, Mexican American, and Pacific Islander youth.
When type 2 diabetes is diagnosed, the pancreas is producing enough insulin, but for some reason the body cannot use the insulin effectively. This is a condition called insulin resistance. Symptoms may not show for many years and by the time they appear, significant problems may already have developed. People with type 2 diabetes are twice as likely to suffer cardiovascular disease. Type 2 diabetes may be treated through dietary changes, exercise and/or tablets. Insulin injections may be required later on because over time, insulin production decreases. The result is the same as for type 1 diabetes. Glucose builds up in the bloodstream and the body simply cannot make good use of its main source of energy.
The symptoms of type 2 diabetes develop more gradually. Symptoms include fatigue, frequent urination, increased thirst and hunger, weight loss, blurred vision, and slow healing of wounds or sores. Some people never show symptoms.
- Gestational Diabetes accounts for 3-8 percent of pregnant woman.
Otherwise known as GDM or carbohydrate intolerance, Gestational diabetes is first diagnosed during pregnancy through an oral glucose tolerance test. Some women develop GDM late in the pregnancy. This form of diabetes usually disappears after the birth of the baby. However, women who develop gestational diabetes have a 40 to 60 percent chance of getting type 2 diabetes within the following 5 to 10 years. Research suggest that maintaining a reasonable body weight and being physically active may help prevent the development of type 2 diabetes.
Women who are diagnosed with GDM typically have a family history of diabetes, increased maternal age, are considered obsese or are a member of a community or ethnic group with a high risk of developing type 2 diabetes.
