Type 1 Diabetes
When the immune system destroys its own beta cells--insulin-producing cells of the pancreas-- a shortage or lack of insulin results, leading to type 1 diabetes. Without insulin, sugar collects in the blood instead of entering cells to provide energy and nutrients.
Formerly known as juvenile diabetes or insulin-dependence, only about five percent of the diabetic community has this form of the disease. While type 1 diabetes generally appears in childhood or adolescence, it can also appear in adults. Factors contributing to type 1 diabetes include inheritance of certain genes and exposure to certain viral infections.
Untreated or poorly managed type 1 diabetes can lead to more serious conditions, including:
- Diabetic ketoacidosis: The body breaks down fat cells to get ketones—an acidic chemical—for energy. As the ketones collect, the blood becomes more acidic. The liver releases its stored sugar to compensate, but without insulin to metabolize the sugar, acid buildup becomes life-threatening.
- Dehydration: The body tries to eliminate excess sugar by urination, taking large amounts of water from the system with it, causing dehydration
- Diabetic coma: This can occur with extreme dehydration when patients are ill and incapable of taking in enough fluids to compensate for fluid loss.
- Weight loss: Excess sugars are eliminated instead of being used for energy or stored in cells, causing weight loss
- Body injury/damage: Prolonged hyperglycemia (high sugar levels in the blood) increases the risk of heart attacks and strokes. The buildup eventually can lead to damage of nerves, large blood vessels, eyes, kidney and heart.
