How does obesity cause diabetes

The evolution from obesity to type 2 diabetes is due to a progressive failure of insulin production that matches with a progressive increase in insulin resistance:. Insulin production failure: When a person is overweight or obese, their body needs to produce more insulin to bring glucose into the cells that make up their adipose tissue, which can lead to a failure in insulin production. This is how the amount of glucose in the blood increases and the pancreas must work hard to produce more insulin to try to keep blood glucose levels within normal levels.

This overexertion causes e pancreas fatigue and consequent reduction of insulin production capacity. Insulin resistance: Excess weight can produce insulin resistance, cells reduce sensitivity, do not respond, to insulin and glucose cannot enter them.

In a normal state, the glucose produced from these digestive processes enters our cells to help with other metabolic processes. The metabolic process is the making and breaking down of food. Insulin acts as a key that unlocks the door to let glucose in to feed our cells. When insulin is present, it also turns off the process of using glycogen from the liver.

This ensures that the glucose levels do not rise further after a meal. Insulin reduces blood glucose by collecting any excess glucose that is present in the bloodstream so that it can be stored as glycogen for future use.

However, if not enough insulin is available, then this glucose is unable to enter cells. Instead, the glucose remains in the bloodstream in a higher than usual amount. This condition is referred to as elevated blood glucose or hyperglycemia.
