Causes of Type 1 and Type 2 Diabetes

The precise cause of type 1 diabetes is not known. What has been determined is that the body’s immune system eliminates it’s own islet cells in the pancreas. The function of the islet cells are to produce insulin. Once the cells are destroyed, the body makes little to no insulin.

Without insulin, the body can’t provide adequate energy to tissues and muscles. When a healthy, non type 1 person eats the pancreas produces normal insulin and it is sent to the bloodstream. From that point, it makes the rounds through the cells in the body and provides the required energy vital for normal function. The liver also plays a vital role in storing and producing insulin. Whenever your insulin levels are running low, the liver will pick up the slack and change stored insulin into back into normal glucose. This lowers the blood sugar and keeps it a normal level.

Because type 1 diabetes there is not enough glucose for the conversion to occur, the normal functions mentioned above do not occur. Rather than being transported back into the bloodstream, the glucose increases to high levels. The high levels of glucose can lead to damaging and potentially fatal consequences. Often, people who have diabetes may have to wear special shoes, such as those found at, to encourage proper circulation and prevent issues related to diabetes.

The most common form of diabetes is type 2. Of all diagnosed cases, only 5 to 10% are non type 2. With this type, the body does produce insulin just not enough for proper use. There can be many causes related to this type of diabetes. It can be a single cause or several factors may contribute to the disease.

Anybody can get type 2 but there are certain factors that may contribute. For example, people who are overweight or morbidly obese are at a high risk for developing type 2 diabetes. Also, people who are inactive or have a genetic predisposition are at risk. Certain ethnic groups are at a higher risk as well. Type 2 diabetes does not form overnight. You will go through an insulin resistant phase, also known as pre-diabetic, prior to full onset diabetes. It can take an individual years to discover that they have type 2 diabetes.
