In Type 1 diabetes, the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas, causing the body to produce little or no insulin. This in turn leads to glucose build-up in the bloodstream instead of going intoth

Type 2 diabetes typically begins with insulin resistance and is usually associated with obesity. Insulin resistance occurs when the body cells do not respond well to insulin and glucose does not enter the cells from the bloodstream. As a result, the body needs more insulin to help glucose to enter the cells. The pancreas would first produce more insulin to keep up with the demands. But over time, the pancreas will not be able to produce sufficient insulin and blood glucose levels goes up. 

Excessive consumption of carbohydrate would increase the risk of type 2 diabetes. As carbohydrate consumption increases blood sugar levels, excessive carbohydrate can cause problems for people with diabetes. There is no known cure for type 1 and type 2 diabetes. Nonetheless, it can be controlled by reducing sugary foods, observing healthy weight management and keeping active.
