Diabetes is a group of metabolic diseases where the body’s pancreas does not produce enough insulin or does not properly respond to insulin produced, resulting in high blood sugar levels over a prolonged period. There are several different types of diabetes, but the most common forms are type 1 and type 2 diabetes. Both impact glucose levels, and if left untreated, can cause many complications
What is type 1 diabetes?
Type 1 diabetes (T1D) can occur at any age, but is most commonly diagnosed from infancy to late 30s. If a person is diagnosed with type 1 diabetes, their pancreas produces little to no insulin, and the body’s immune system destroys the insulin-producing cells in the pancreas. What is type 2 diabetes?
Type 2 diabetes (T2D) typically develops after age 40, but has recently begun to appear with more frequency in children. If a person is diagnosed with type 2 diabetes, their pancreas still produces insulin, but the body does not produce enough or is not able to use it effectively.
What causes diabetes type 1 and type 2?
Diabetes may arise because the pancreatic beta cells, which produce insulin, are destroyed by an autoimmune disorder, giving rise to type I diabetes. Alternatively, the body cells may not respond to insulin that is being made at the proper levels (insulin resistance) resulting in type 2 diabetes, often as a result of obesity, and deficient insulin secretion.
Insulin use not only prevents hyperglycemic emergencies, but also is the best safeguard to prevent the long-term complications of diabetes by correcting fasting and postprandial hyperglycemia.
Both of these major diabetes types are believed to include different stages of disease, ranging from non-insulin-requiring to insulin-requiring for control or survival.
Diabetes type 1
Diabetes type 2
Cause
Beta cells in pancreas are being attacked by body's own cells and therefore can not produce insulin to take sugar out of the blood stream. Insulin is not produced.
