Causes of Diabetes

Diabetes mellitus occurs when the pancreas doesn't make enough or any of the hormone insulin, or when the insulin produced doesn't work effectively. In diabetes, this causes the level of glucose in the blood to be too high.

In Type 1 diabetes the cells in the pancreas that make insulin are destroyed, causing a severe lack of insulin. This is thought to be the result of the body attacking and destroying its own cells in the pancreas - known as an autoimmune reaction.

It's not clear why this happens, but a number of explanations and possible triggers of this reaction have been proposed. These include:

infection with a specific virus or bacteria;
exposure to food-borne chemical toxins; and
exposure as a very young infant to cow's milk, where an as yet unidentified component of this triggers the autoimmune reaction in the body.
However, these are only hypotheses and are by no means proven causes.

Type 2 diabetes is believed to develop when:

the receptors on cells in the body that normally respond to the action of insulin fail to be stimulated by it - this is known as insulin resistance. In response to this more insulin may be produced, and this over-production exhausts the insulin-manufacturing cells in the pancreas;
there is simply insufficient insulin available; and
the insulin that is available may be abnormal and therefore doesn't work properly.
The following risk factors increase the chances of someone developing Type 2 diabetes:

Increasing age;
obesity; and
physical inactivity.
Rarer causes of diabetes include:

Certain medicines;
pregnancy (gestational diabetes); and
any illness or disease that damages the pancreas and affects its ability to produce insulin e.g. pancreatitis.
What doesn't cause diabetes
It's important to also be aware of the different myths that over the years have arisen about the causes of diabetes.

Eating sweets or the wrong kind of food does not cause diabetes. However, it may cause obesity and this is associated with people developing Type 2 diabetes.

Stress does not cause diabetes, although it may be a trigger for the body turning on itself as in the case of Type 1 diabetes. It does, however, make the symptoms worse for those who already have diabetes.

Diabetes is not contagious. Someone with diabetes cannot pass it on to anyone else.

Causes of Diabetes

Drugs such as steroids, Dilantin, and others may elevate the blood sugar through a variety of mechanisms. Certain other drugs, such as alloxan, streptozocin, and thiazide diuretics, are toxic to the beta cells of the pancreas and can cause diabetes. Certain syndromes (for example, Prader-Willi, Down's, Progeria, and Turner's) may result in a hyperglycemic state; if this state is prolonged, the result can be permanent diabetes.

Diabetes resulting in an insulin-dependent state is classified as Type 1 diabetes. While Type 1 diabetes affects only between 5 to10 percent of the diabetic population, its effects on the body can be worse than other forms of diabetes. In the past, Type 1 has been known as juvenile or juvenile-onset diabetes (because it is usually diagnosed in those under thirty), brittle diabetes, unstable diabetes, and ketosis-prone diabetes. People in this classification more frequently exhibit the classic symptoms, usually with ketones present in blood and urine. A blood-sugar level of 800 mg/dl (44 mmol) or more, especially if ketones are not present, indicates a diagnosis of hyperglycemic hyperosmolar nonketotic syndrome (a state in which the body is extremely dry (dehydrated), the chemicals in the body are concentrated, and the blood sugar is high).

As stated before, diabetes is a syndrome or group of diseases (rather than one disease), leading to the prolonged hyperglycemic state. Type 1 is most associated with the killing of the beta cells, most likely by the body's own immune system. Either the immune system cannot kill an infecting agent, which then kills the beta cells, or the immune system itself goes "wild," attacking the body's own tissue and destroying the beta cells. The cells of the islets of Langerhans are inflamed, resulting from an infectious-disease process (for example, mumps) or, more commonly, from an autoimmune (allergic to self) response.

The autoimmune process results in the circulation of antibodies that may either cause or be caused by beta-cell death. If it is found that the antibodies cause beta-cell destruction (the body fighting what it now considers foreign to itself), the body's response to the Type 1 diabetes is much less severe (i.e., easier to control) with treatment. Until then, the outcome is a lack of available insulin. While the onset is said to be sudden, changes resulting in decreased insulin availability may have occurred over a longer period of time. In short, insulin-dependent diabetes mellitus is an inherited defect of the body's immune system, resulting in destruction of the insulin-producing beta cells of the pancreas.

Heredity is a major cause of diabetes. If both parents have Type 2 diabetes, there is a chance that nearly all of their children will have diabetes. If both parents have Type 1 diabetes, fewer than 20 percent of their children will develop Type 1 diabetes. In identical twins, if one twin develops Type 2 diabetes, the chance is nearly 100 percent that the other twin will also develop it. In Type 1 diabetes, however, only 40 to 50 percent of the second twins will develop the disease, indicating that while inheritance is important, environmental factors (for example, too much food, too much stress, viral infection, and so forth) are also involved in the development of Type 1 diabetes.

I am writing to tell you what an incredible impact these methods had on my life! I have had type 2 diabetes for 27 years. For me, the worst part of this horrible disease is the severe pain I constantly get in my feet. The pain is so bad that I avoid standing and walking as much as possible. I've got to tell you that within the first month, my feet stopped hurting altogether and I can now walk totally pain free.

Believe it or not, I even danced at my niece's wedding last month, something I have not done in a many years. I've been following the book for six months now and my blood sugar is well within normal range. I feel great!

Answer 6

there are 2 different kinds of diabetes, type 1 and type 2.

Type 1 diabetes occurs when the body's own immune system destroys the insulin-producing cells of the pancreas (called beta cells).

Normally, the body's immune system fights off foreign invaders like viruses or bacteria. But for unknown reasons, in people with type 1 diabetes, the immune system attacks various cells in the body. This results in a complete deficiency of the insulin hormone.

Some people develop a type of diabetes – called secondary diabetes -- which is similar to type 1 diabetes, but the beta cells are not destroyed by the immune system but by some other factor, such as cystic fibrosis or pancreatic surgery.

Type 2 diabetes, often called non-insulin dependant diabetes, is the most common form of diabetes, affecting 90% - 95% of the 18.2 million people with diabetes.

Unlike people with type 1 diabetes, people with type 2 diabetes produce insulin; however, the insulin their pancreas secretes is either not enough or the body is unable to recognize the insulin and use it properly. This is called insulin-resistance. When there isn't enough insulin or the insulin is not used as it should be, glucose (sugar) can't get into the body's cells. When glucose builds up in the blood instead of going into cells, the body's cells are not able to function properly.

Answer 8

There is only a 3-5% chance of a type 1 diabetic having a family member also with type 1. Type 2 is genetic and preventable. With type 2 there is a 30+ % chance.

Answer 9

High blood levels of glucose can cause several problems, including frequent urination, excessive thirst, hunger, fatigue, weight loss, and blurry vision. However, because type 2 diabetes develops slowly, some people with high blood sugar experience no symptoms at all. How to treat diabetes naturally https://tr.im/VSmAq

Symptoms of type 1 diabetes:

Increased thirst
Increased urination
Weight loss in spite of increased appetite
Fatigue
Nausea
Vomiting

Patients with type 1 diabetes usually develop symptoms over a short period of time, and the condition is often diagnosed in an emergency setting.

Symptoms of type 2 diabetes:

Increased thirst
Increased urination
Increased appetite
Fatigue
Blurred vision
Slow-healing infections
Impotence in men



If you think you have diabetes i think you should have a checkup and speak with your doctor just in case.

Answer 10

It could be a genetic predisposition to it (one of your parents or siblings had it, it runs in your family), of course that's typically type 1. Type 2 is usually a result of diet (and not a bunch of sugars and stuff although that doesn't help) and exercise (lack there of). Diabetes is not enough insulin in the body to process the sugar in the blood, which diabetics have too much of even before you consider diet. For further information go here:

Answer 11

diabetes is sometimes hereditary,most people get the disease when pancreas does not produce enough insulin.type 1 diabetes needs insulin injections and rigorous weight control and dietary restrictions.Actually type 2 diabetes can be controlled by exercise and diet.smoking must be stopped.Alcohol in moderation and also watch for lipids level because diabetes affects heart also.wounds don't heal in the normal way.Foot-care is most essential.
