Type 2 diabetes occurs when cells resist the effects of insulin, and the pancreas isn't functioning properly.he cells are resistant to the action of insulin requiring the pancreas to make more insulin to get cells to respond. Eventually, the pancreas becomes fatigued and can't keep up with the demand and blood sugar rises. This continual cycle leads to an increase in blood sugar levels, sometimes to a dangerous or risky point.
Insulin is a hormone produced by the pancreas to help sugar enter the cells in your body for use as energy. In Type 2 DM, the cells are resistant to the action of insulin requiring the pancreas to make more insulin to get cells to respond. Eventually, the pancreas becomes fatigued and can't keep up with the demand and your blood sugar rises.
The longer someone is living with any type of undiagnosed diabetes, the greater the chance of serious health problems, such as heart disease, vision loss, and kidney disease due to the high sugar level in the body.
