type 1 diabetes is what type of hypersensitivity?

Management of type 1 diabetes in patients who have insulin hypersensitivity is a clinical challenge and places patients at risk for recurrent diabetic ketoacidosis (DKA). Hypersensitivity reactions can be due to the patient's response to the insulin molecule itself or one of the injection's non-insulin components.

This form is typically caused by an autoimmune disorder, meaning that the body's immune system mistakenly attacks cells that make insulin. In some people, type 1 diabetes may occur after a viral infection, such as cytomegalovirus, encephalitis, Epstein-Barr virus, influenza, measles, mumps, polio, or rubella.

Long-term high blood sugar levels in people with type 1 diabetes appears to result in chronic inflammation, researchers say, which can impair organs, nerves and blood vessels.

The exact cause of type 1 diabetes is unknown. Usually, the body's own immune system — which normally fights harmful bacteria and viruses — mistakenly destroys the insulin-producing (islet, or islets of Langerhans) cells in the pancreas. Other possible causes include: Genetics.

Type 1 diabetes can develop at any age. Adults may develop a specific form of type 1 diabetes known as LADA (latent autoimmune diabetes of adulthood). LADA tends to develop more slowly than type 1 diabetes in children and young adults and people with LADA may sometimes be misdiagnosed as having type 2 diabetes.

Type 1 diabetes is a disorder in which the pancreas fails to produce enough insulin. This can be detected from an early age. It is characterised by uncontrolled high blood glucose levels and it can be controlled by injecting insulin.

Type 1 diabetes occurs when your immune system, the body's system for fighting infection, attacks and destroys the insulin-producing beta cells of the pancreas. Scientists think type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease.

Type I occurs when the pancreas does not make enough insulin, and type II occurs when the body can not respond normally to the amount of insulin made by the pancreas. Although diabetes in pets is sometimes classified as Type I or II, the difference between the types is less clear in pets than it is in humans.

“The autoimmune part of type 1 diabetes is very particular, as only the beta cells in the islets are targeted — not the other cells in the islet, and not the other cells in the pancreas. In all of the usual ways, the immune system is just fine,” he says.

The exact cause of type 1 diabetes is unknown. But in most people with type 1 diabetes, the body's immune system — which normally fights harmful bacteria and viruses — mistakenly destroys insulin-producing (islet) cells in the pancreas. Genetics and environmental factors appear to play a role in this process.

The disruption in glucose metabolism in patient with type 1 diabetes causes skin changes. Type 1 diabetics are at a higher risk for bacterial infections and fungal infections. Poor blood circulation in the skin may also occur.

Quick facts about type 1 diabetes The number of new diagnoses of type 1 diabetes (also known as the incidence) is increasing by about four per cent each year. In children under five, the incidence of type 1 diabetes is rising by five per cent each year.

Type 1 diabetes (previously called insulin-dependent or juvenile diabetes) is usually diagnosed in children, teens, and young adults, but it can develop at any age. Type 1 diabetes is less common than type 2—approximately 5-10% of people with diabetes have type 1.

There are 2 main types of diabetes: type 1 diabetes – where the body's immune system attacks and destroys the cells that produce insulin. type 2 diabetes – where the body does not produce enough insulin, or the body's cells do not react to insulin.

People with type 1 diabetes produce antibodies that destroy their insulin-producing cells, so they need daily insulin injections. There is currently no cure for the condition.

Insulin resistance isn't a cause of type 1 diabetes, but people with type 1 who are insulin resistant will need higher insulin doses to keep their blood glucose under control than those who are more sensitive to insulin. As with type 2, people with type 1 may be genetically predisposed to become insulin resistant.
