Diabetes, also known as diabetes mellitus, is a group of common endocrine diseases characterized by sustained high blood sugar levels. [ 10 ] [ 11 ] Diabetes is due to either the pancreas not producing enough insulin , or the cells of the body becoming unresponsive to the hormone's effects. [ 12 ]
Diabetes mellitus type 1 is caused by insufficient or non-existent production of insulin, while type 2 is primarily due to a decreased response to insulin in the tissues of the body (insulin resistance). Both types of diabetes, if untreated, result in too much glucose remaining in the blood (hyperglycemia) and many
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. [6] Common symptoms include increased thirst , frequent urination , fatigue and unexplained weight loss . [ 3 ]
The result of NAFLD is an excessive release of free fatty acids into the bloodstream (due to increased lipolysis), and an increase in hepatic breakdown of glycogen stores into glucose (glycogenolysis), both of which have the effect of exacerbating peripheral insulin resistance and increasing the likelihood of Type 2 diabetes mellitus.
Namely, those counter-regulatory mechanisms are glucagon and epinephrine. The process of the regulation of blood glucose (also known as glucose homeostasis) also exhibits oscillatory behavior. On a pathological basis, this topic is crucial to understanding certain disorders in the body such as diabetes, hyperglycemia and hypoglycemia.
The pancreas is central in the pathophysiology of both major types of diabetes mellitus. In type 1 diabetes mellitus, there is direct damage to the endocrine pancreas that results in insufficient insulin synthesis and secretion. Type 2 diabetes mellitus, which begins with insulin resistance, is characterized by the ultimate failure of ...
Diabetes mellitus is diagnosed when the blood glucose levels get too high, and this is seen among 10% of the world population. There are two types of diabetes - Type 1 and Type 2, and the main difference between them is the underlying mechanism that causes the blood glucose levels to rise.
The polyol pathway is a two-step process that converts glucose to fructose. [1] In this pathway glucose is reduced to sorbitol, which is subsequently oxidized to fructose. It is also called the sorbitol-aldose reductase pathway. The pathway is implicated in diabetic complications, especially in microvascular damage to the retina, [2] kidney, [3 ...
