Thank you. I understand now :)

Hi Elizabeth,

Type 1 Diabetes occurs when the cells in the pancreas which produce insulin are completely destroyed and cannot make insulin anymore. The most commonly cited cause is related to certain environmental conditions which contribute to cell damage. Insulin helps to transport sugars so that the sugars can be converted into energy and used by your body's tissues. In people who do not make insulin, the sugar just hangs out and is virtually unusable by the body. This is why when you check a diabetic's blood sugar, who is untreated, it can be exceptionally high depending on their diet.

Type 2 Diabetes occurs when your pancreas does not produce enough insulin to keep up with your body's demands - or - your cells aren't as responsive to your natural insulin - or - both. The same sorts of issues tend to occur in Type 2 diabetics, in that the sugars build up but are not able to be used. In the case of Type 2 Diabetes, injectable insulin is not always the best option. Often oral glucose lowering agents are used first.

I am guessing you meant Type-1 and Type-2 diabetes, type one diabetics cannot produce insulin within their pancreas and must utilize injectable insulin to remove glucose (sugar) from their blood.  Type-2 diabetics can produce insulin from their pancreas however, sometime it is not enough or it is insensitive and does not clear out the glucose from the blood and these type-2 diabetics usually take oral drugs such as sulfonylurias to increase insulin from tour pancreas.
