Pre-gestational diabetes can be classified as Type 1 or Type 2 depending on the physiological mechanism. Type 1 diabetes mellitus is an autoimmune disorder leading to destruction of insulin-producing cell in the pancreas; type 2 diabetes mellitus is associated with obesity and results from a combination of insulin resistance and insufficient insulin production.
Cardiovascular disease. Improving your diet and exercise habits can also improve your insulin sensitivity. Also, some causes of insulin resistance, like pregnancy, are temporary.
Insulin is a hormone that facilitates the transport of glucose from blood into cells, thereby reducing blood glucose (blood sugar). Insulin is released by the pancreas in response to carbohydrates consumed in the diet. In states of insulin resistance, the same amount of insulin does not have the same effect on glucose transport and blood sugar ...
More insulin is needed to overcome this resistance; about 1.5–2.5 times more insulin is produced than in a normal pregnancy. [27] Insulin resistance is a normal phenomenon emerging in the second trimester of pregnancy, which in cases of GDM progresses thereafter to levels seen in a non-pregnant woman with type 2 diabetes.
Too low a level of blood glucose (i.e., 'sugar') in the blood; also called hypoglycemia. This occurs when a person with diabetes has injected too much insulin, eaten too little food, or exercised without compensating for the increased glucose uptake caused by exercise. The person may feel hungry, nauseated, weak, nervous, shaky, confused, and ...
By far, the most common cause of severe hypoglycemia in this age range is insulin injected for type 1 diabetes. Circumstances should provide clues fairly quickly for the new diseases causing severe hypoglycemia.
Obesity has been found to contribute to approximately 55% of cases of type 2 diabetes; [10] chronic obesity leads to increased insulin resistance that can develop into type 2 diabetes, [11] most likely because adipose tissue (especially that in the abdomen around internal organs) is a source of several chemical signals, hormones and cytokines, to other tissues.
Hyperinsulinemia is a condition in which there are excess levels of insulin circulating in the blood relative to the level of glucose. While it is often mistaken for diabetes or hyperglycaemia, hyperinsulinemia can result from a variety of metabolic diseases and conditions, as well as non-nutritive sugars in the diet.
