Type 1 diabetes (T1D), formerly known as juvenile diabetes, is an autoimmune disease that occurs when the body's immune system destroys pancreatic cells (beta cells). [5] In healthy persons, beta cells produce insulin. Insulin is a hormone required by the body to store and convert blood sugar into energy. [6]
Gestational diabetes – Gestational diabetes, is a temporary condition that is first diagnosed during pregnancy. Like type 1 and type 2 diabetes, gestational diabetes causes blood sugar levels to become too high. It involves an increased risk of developing diabetes for both mother and child.
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 ...
A summary of the pathophysiology of a type 1 hypersensitivity reaction. Type I hypersensitivity can be further classified into immediate and late-phase reactions. Within minutes of exposure to an antigen, the immediate hypersensitivity occurs, releasing histamines and lipid mediators which are responsible for the initial allergic reaction response.
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
Most young Type 1 diabetic patients experience glomerular hyperfiltration, a typical functional deviation in insulin-dependent diabetes mellitus. [4] A meta-analysis of research done on Type 1 diabetic subjects found that people with glomerular hyperfiltration have a higher chance of developing albuminuria and seeing their diabetic nephropathy worsen. [5]
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 ...
The mean age at presentation is thirty-seven years with a reported range of nineteen to sixty-four years. The mean age of onset since diagnosis of diabetes is fifteen years. The female:male ratio is 1.3:1. Other diabetic complications such as nephropathy, neuropathy, retinopathy and hypertension are usually present. Its major symptom is the ...
