Diabetes Causes And Risk Factors

What Are the Causes?

The pancreas produces insulin, which is a hormone that helps the body convert glucose into energy. When the pancreas fails to produce enough insulin, the body cannot adequately break down sugar, and when the body ceases to respond to insulin, an excess of sugar and insulin can build up in the body. Both situations cause a person to develop diabetes.

Type 1 diabetes occurs when the body cannot produce enough insulin. People with type 1 diabetes may produce a small amount of insulin or none at all. As a result, an excess of glucose will build up in the bloodstream since the body cannot sufficiently break it down into energy.

When insulin accumulates in the body, you may feel hungry or thirsty, and you may experience a need to urinate frequently. Your type 1 diabetes might also be causing your fatigue, hunger, weight loss, blurry eyesight, nerve damage, numbness, or tingling in the legs. If your diabetes is left untreated, your symptoms can escalate and become more serious. You may develop permanent complications that include organ failure, severe nerve damage, and even death.

Type 1 diabetes is also known as insulin-dependent and juvenile diabetes. Many people develop type 1 diabetes as children; however, it's possible to develop type 1 diabetes at any age, even as adults. Most people who develop the condition as children will learn how to take insulin injections and monitor their diets.

It is believed that genetics are responsible for causing type 1 diabetes. Environmental factors, viruses, and autoimmune conditions can also trigger the condition to develop. Changes in diet and exercising may help treat symptoms; however, dieting and exercising cannot prevent the condition from developing.

Unlike type 1 diabetes, type 2 diabetes is more closely related to diet and exercise. This type of diabetes causes insulin resistance. When a person becomes resistant to insulin, their liver, fat cells, and muscle cells no longer respond to insulin. As a result, an excess of both insulin and glucose build up in the bloodstream. The pancreas will continue to produce more and more insulin.

Type 2 diabetes will cause you develop symptoms that included blurred vision, erectile dysfunction, exhaustion, increased appetite, thirst, and a frequent urge to urinate.

Type 3 diabetes occurs when the brain stops sending signals for the production of insulin. Because type 3 diabetes was discovered relatively recently in 2005, little is known about the condition. It is believed that type 3 diabetes has a genetic link with Alzheimer's disease.

Both low glucose levels and high glucose levels can cause problems. If your blood sugar is high, you might feel tired, hungry, and thirsty. Your vision might become blurry, and you might experience heart palpitations, stomach pain, flushing in your face, and nausea. If you have low blood sugar, you might develop a headache, feel hungry, start trembling begin sweating, or feel week.

Diabetes can cause a variety of problems including organ failure, shock, and infections that are so severe that amputation is required.

Who's at Risk?

Family history can help predict risk factors for type 1 diabetes. A person with a parent, brother, or sister with type 1 diabetes could develop the condition. Certain genes have also been linked with type 1 diabetes. Certain viruses such as the mumps have been known to trigger type 1 diabetes. Even though type 1 diabetes is difficult to predict, it is believed that genetics are the biggest indicators.

Your diet and lifestyle can influence your type 1 diabetes, but it is unlikely that your diet and lifestyle cause your type 1 diabetes. In any case, if you are obese or if you live a sedentary lifestyle, the possibility that you will develop complications is much higher.

High risk groups for type 2 diabetes include people who are overweight and over 40 years old. A person who consumes excessive amounts of sugar is also likely to develop type 2 diabetes. You don't need to be overweight to develop type 2 diabetes. The condition is common among people who are thin. People with high blood pressure, high cholesterol, and a family history of diabetes are at risk.

Type 3 diabetes was discovered recently, and there is little research available to identify risk factors. It is believed that type 3 diabetes is strongly linked to Alzheimer's.
