How Type 2 Diabetes Develops
Type 2 diabetes is different. The autoimmune systems of people with type 2 diabetes dont attack beta cells. Instead, type 2 diabetes is characterised by the body losing its ability to respond to insulin. This is known as insulin resistance
The body compensates for the ineffectiveness of its insulin by producing more, but it cant always produce enough. Over time, the strain placed on the beta cells by this level of insulin production can destroy them, diminishing insulin production.
What Is Type 1 Diabetes
People of all ages can develop type 1 diabetes.
If you have type 1 diabetes, your pancreas doesnt make insulin or makes very little insulin. Insulin is a hormone that helps blood sugar enter the cells in your body where it can be used for energy. Without insulin, blood sugar cant get into cells and builds up in the bloodstream. High blood sugar is damaging to the body and causes many of the symptoms and complications of diabetes.
Type 1 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 2approximately 5-10% of people with diabetes have type 1. Currently, no one knows how to prevent type 1 diabetes, but it can be managed by following your doctors recommendations for living a healthy lifestyle, managing your blood sugar, getting regular health checkups, and getting diabetes self-management education and support.
Type 2 Diabetes Risk Factors
A number of factors my increase your risk of type 2 diabetes:
- If other members of your family have Type 2 diabetes, this increases your risk of getting the condition.
- If you are overweight you will significantly increase your risk of developing Type 2 diabetes. Almost all those affected by this condition are overweight. Your waist measurement is a good yardstick of your weight.
- If you have high blood pressure or increased amounts of lipids in the blood.
- If youve had a blood clot in the arteries supplying the heart or a stroke.
- If youre on certain types of medications, especially corticosteroids or diuretics.
- If you are South Asian or African Caribbean.

Bdiseases With An Immune Component
The immune disorders encompass arthritis, psoriasis, inflammatory bowel disease , systemic lupus erythematosus , chronic obstructive pulmonary disease , asthma, allergies, and atopic dermatitis.
Insulin-dependent diabetes mellitus , atherosclerosis, and cancer also have an immune component. Type 1 diabetes arises from the destruction of beta cells of the pancreas by white blood cells . In atherosclerosis, the infiltration of macrophages in the coronary artery results in atherosclerotic plaques .
A distinguishing feature of cancer, on the other hand, is absence of an immune response, where this absence results from the fact that antigens of tumor cells are identical to, or have structures very similar to, antigens of normal host cells.
Immune disorders such as multiple sclerosis and rheumatoid arthritis are classified as autoimmune diseases because pathological lesions result from immune attack against the hosts own antigens. Other immune disorders, such as asthma and allergies, are merely classed as inflammatory disorders, because the pathology does not involve attack against specific host antigens. Inflammatory disorders also encompass collateral damage to the liver from an overly active immune system during immune response against hepatitis C virus.

Allele Sharing By Affected Sibpairs
A microsatellite marker in the 3 untranslated region and the +49 A/G polymorphism in exon 1 of CTLA4 were genotyped for all French, Spanish and Caucasian-American families with two affected siblings . Gene sharing by affected sibpairs was calculated using the haplotype data derived from the CTLA4 A/G and n polymorphisms. Analysis of these families revealed a slight increase in haplotype sharing by affected sibpairs compared to the randomly expected 50% distribution . The increase was, however, not statistically significant.
Diabetes: Facts Statistics And You
Diabetes mellitus is a term for a group of disorders that cause elevated blood sugar levels in the body.
Glucose is a critical source of energy for your:
When you eat, your body breaks down carbohydrates into glucose. This triggers the pancreas to release a hormone called insulin, which acts as a key that allows glucose to enter the cells from the blood.
If your body doesnt produce enough insulin to effectively manage glucose, it cant function or perform properly. This leads to symptoms of diabetes.
Diabetes thats not well managed can cause serious complications by damaging blood vessels and organs. It can increase the risk of:

The Difference Between Type 1 And Type 2
30.3 million people have diabetes , in one type or another. 84.1 million adults aged 18 years or older have prediabetes (33.9% of the adult US population. But what exactly is Diabetes? There are a lot of myths and misunderstandings surrounding the disease, particularly when it comes to type 1 versus type 2.
So lets start with the basics.
The two main types of diabetes are type 1 and type 2. In type 1 diabetes , the body completely stops making insulin. People with type 1 diabetes must take daily insulin injections to survive. This form of diabetes usually develops in children or young adults, but can occur at any age.In type 2 diabetes the body produces insulin, but the cells dont respond to insulin the way they should. This is called insulin resistance. In response to this insulin resistance, the pancreas should make more insulin, but in the case of type 2 diabetes, this does not happen. Because of these two problems, insulin resistance and trouble making extra insulin, there is not enough of an insulin effect to move the glucose from the blood into the cells. Type 2 diabetes is more likely to occur in people who are over the age of 40, overweight, and have a family history of diabetes, although more and more younger people, including adolescents, are developing type 2 diabetes.
Its important to know a few things about how your body works before you can take the best care of your diabetes.

Signs And Symptoms Of Type 2 Diabetes
When you have type 2 diabetes your body cant get enough glucose into your cells, so a common symptom is feeling very tired. There are also other symptoms to look out for. These include feeling thirsty, going to the toilet a lot and losing weight without trying to.
The symptoms of type 2 diabetes can develop more slowly than the symptoms of type 1 diabetes, making the condition harder to spot. Thats why a lot of people dont get any symptoms, or dont notice them.
Some people also dont think the symptoms are important, so dont ask for help. This means some people can live for up to 10 years with type 2 diabetes before being diagnosed.

Animal Models In Dm Type 1 Research
Animal models are used in autoimmune diabetes research to understand the pathogenesis and etiology of this disease, and to find and test predictive biomarkers and therapeutic interventions. Currently available models of T1D can be divided into spontaneously autoimmune, chemically induced, virus induced and genetically induced.
- Non-obese diabetic mouse
The NOD mouse is the best known and most widely used animal model for type 1 DM research. It is an inbred, genetically well characterized mouse strain that spontaneously develops T1D. The onset of insulitis occurs at 3â4 weeks of age. The islets of Langerhans are infiltrated by CD4+, CD8+ T lymphocytes, NK cells, B lymphocytes, dendritic cells, macrophages and neutrophils, similar to the disease process in humans. Insulitis leads to destruction of Î²-cells, resulting in the apparent occurrence of T1D, which varies by sex. The incidence is about 60-80% in females and 10-30% in males. In addition to sex, breeding conditions, gut microbiome composition or diet also influence the onset of T1D. NOD Mice are used to understand the pathogenesis and etiology of the disease, to identify novel autoantigens and biomarkers or to test new intervention strategies.

Type I Diabetes: Insulin
Type I diabetes is also known as insulin-dependent diabetes or juvenile diabetes. This form of diabetes is mainly found in children. The primary problem in all forms of diabetes, regardless if it is Type I or Type II is that the glucose levels of the body are too high.
In a healthy person, the beta cells in the pancreas produce a hormone called insulin in response to sugar in the blood. The sugar gets there through the food and drinks we consume. Normally, the insulin helps to move the sugar from the bloodstream and into the cells of the body where it can be used for cellular processes. The insulin triggers gates located in the membranes of the cells to open, allowing the sugar to flow in.
A person with Type I diabetes can not make enough or any insulin. This produces the abnormally high levels of glucose in the bloodstream seen in these patients.
The question begs to be asked, Why doesnt the body produce insulin? In Type I diabetes the culprit is the immune system. Something, whether it be genetic or environmental is still not clear, triggers the immune system to malfunction. Instead of viewing the beta cells of the pancreas as self, the immune system sees the beta cells as foreign invaders. Doing what its supposed to do, which is attack and destroy invading cells, the immune system in error attacks the beta cells.

What Happens In Type 1 Diabetes
The cause of diabetes is not known. Some experts believe diabetes is inherited , but the genetics are not clearly understood. Diabetes does not always run in families. The body mistakes the cells that produce insulin for foreign cells. The body then destroys these cells. This is called an auto-immune process. Although something in the environment may trigger the disease, there are no known ways to prevent type 1 diabetes in children.

What Causes Glucose In The Urine
The kidneys filter waste products and excess water out of the blood. When the glucose in the blood is above normal level, the kidneys cant hold it all. The glucose then shows up in the urine. The glucose in the urine causes the urine output to increase in frequency and amount. This increase causes you to be thirstier.

What Causes Type 1 Diabetes
Type 1 diabetes is thought to be caused by an autoimmune reaction that destroys the cells in the pancreas that make insulin, called beta cells. This process can go on for months or years before any symptoms appear.
Some people have certain genes that make them more likely to develop type 1 diabetes, though many wont go on to have type 1 diabetes even if they have the genes. Being exposed to a trigger in the environment, such as a virus, is also thought to play a part in developing type 1 diabetes. Diet and lifestyle habits dont cause type 1 diabetes.
Can Type 2 Diabetes Be Cured
There is no cure for type 2 diabetes, but some people are able to put their diabetes into remission. This means that your blood sugar levels are healthy and you dont need to take diabetes medication any more. Remission can be life-changing, but its not possible for everyone.

What Is Insulin Dependent Diabetes
The blue circle is the international symbol for diabetes, both Type 1 and Type 2. Both are conditions marked by irregular blood sugar as diseases, they live under the same roof but theyre as different as Sherlock and Watson.
Most people with diabetes have Type 2, which typically occurs in adulthood and is often diet related. But 5 to 10 percent of people living with diabetes have Type 1, also called insulin-dependent diabetes. Because it is deadly if untreated and is on the rise worldwide, everyone should know the symptoms and how this autoimmune disease is managed.
Unlike Type 2, which develops over time, the onset of insulin dependent diabetes is sudden.. One day, youre fine the next, youre experiencing fatigue, extreme hunger, frequent urination, blurred vision, tingling and numbness in your feet, and dry skin and mouth. You are nearing or already in the state called hyperglycemia, in which your blood sugar level is too high.
To add insult to injury, your own body has done this to itself, by destroying essential cells.
These cells would be the beta cells of the pancreas, and their job is to make insulin, the hormone that enables sugar to pass from the bloodstream to our cells. Think of insulin as a key that unlocks the door through which sugar passes, and then distributes energy to the millions of cells all over the body.
How is Insulin Dependent Diabetes Treated?
What Is A Diabetes Meal Plan
There’s no “magic” diabetes diet. However, there are dietary recommendations for people with diabetes. Diet methods for managing both type 1 and type 2 diabetes include:
- Carbohydrate counting
Signs and symptoms of diabetes, whether type 1 or type 2, do not differ.
- Early diabetes may not produce any symptoms at all.
- When symptoms do occur, the age of onset is typically different, with type 1 diabetes being diagnosed most often in younger people , while type 2 diabetes is diagnosed more commonly in adults. However, this is not always the case.
- The increasing incidence of obesity among children and adolescents has caused a rise in the development of type 2 diabetes in young people.
- Further, some adults with diabetes may be diagnosed with a form of late-onset type 1 diabetes.

What Causes Insulin Dependent Diabetes Mellitus
Usually, the body’s own immune system which normally fights harmful bacteria and viruses mistakenly destroys the insulin-producing cells in the pancreas. Other possible causes include: Genetics. Exposure to viruses and other environmental factors.
Thereof, what are the causes of diabetes mellitus?
Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally. This is called an autoimmune reaction, or autoimmune cause, because the body is attacking itself.
Beside above, are all diabetics insulin dependent? Insulin dependent diabetes mellitus , also known as type 1 diabetes, usually starts before 15 years of age, but can occur in adults also. Insulin is the key that allows glucose to enter the cells. Without this key, glucose stays in the bloodstream and the cells can’t use it for energy.
Accordingly, why is type 2 diabetes non insulin dependent?
In type 2 diabetes, the glucose is not taken into the cells. This is referred to as insulin resistance. It causes glucose to stay in the blood stream and hyperglycaemia is the result. Type 2 diabetes mellitus was previously called non–insulin dependent diabetes mellitus and late onset diabetes mellitus.

Actions Before Undertaking Any Flight Operations
To ensure safe flight, the insulin-using diabetic aviator must carry:
- two recording devices during flight, preferably a Continuous Glucose Monitoring System and a back-up glucometer
- adequate supplies to obtain blood samples
- an amount of rapidly absorbable glucose in 15 gm portions, appropriate to the planned duration of the flight.
The aviator must discuss this protocol with his treating physician and obtain advice as to the best combination of food intake/ medication that will optimise the glycaemic control without adversely affecting safety.
