Signs and symptoms of type 2 diabetes often develop slowly. In fact, you may have type 2 diabetes for years and do not know it. Search:

When you see a doctor
Consult your doctor if you notice type 2 diabetes.
Type 2 diabetes develops when the body becomes insulin-resistant or when the pancreas can not produce enough insulin. The exact cause of this is unknown, although genetic and environmental factors, such as weight gain and inactivity, seem to be contributing factors.
How Insulin works
Insulin is a hormone that comes from the gland located behind and under the stomach (pancreas).
The pancreas secrete insulin in the bloodstream.
Insulin circulates and allows sugar to enter the cells.
Insulin reduces the amount of sugar in the bloodstream.
With low blood sugar, the secretion of insulin from the pancreas is diminished.
The role of glucose.
Glucose, sugar, is a major source of energy for the cells that make up the muscles and other tissues.
Glucose comes from two main sources: food and liver.
Sugar is absorbed into the blood stream, where it enters cells with the help of insulin.
The liver stores and produces glucose.
When glucose levels are low, such as not eaten for a long time, the glycogen-stored liver breaks down in glucose to maintain a normal glucose level.
In type 2 diabetes, this process does not work well. Instead of moving to cells, sugar accumulates in the bloodstream. As blood sugar levels rise, insulin-producing beta cells in the pancreas release more insulin, but eventually these cells deteriorate and can not produce enough insulin to meet the body's requirements.
In the first type of diabetes, which is less common, the immune system mistakenly destroys beta cells, leaves the body without insulin or does not contain any type of insulin.
Factors that may increase the risk of type 2 diabetes include:
the weight. Weight gain is a major risk factor for type 2 diabetes. However, you do not have to be overweight to develop type 2 diabetes.
Fat distribution. If you store fat mainly in the abdomen, you have a risk of type 2 diabetes compared to storing fat elsewhere, such as hips and thighs. The risk of type 2 diabetes increases if you are a man with a circumference of more than 40 inches (101.6 centimeters) or a woman with a waist greater than 35 inches (88.9 centimeters).
Idle. The lower your activity, the higher your risk of type 2 diabetes. Physical activity helps you control your weight, uses glucose as energy and makes your cells more sensitive to insulin.
Family history The risk of type 2 diabetes increases if your father or brother has type 2 diabetes.
Profession. Although it is not clear why, people of certain races, including blacks, Latins, American Indians and Asian Americans, are more likely to develop type 2 diabetes than whites.
Years. The risk of developing type 2 diabetes increases with age, especially after the age of 45. This may be because people tend to exercise less, lose muscle mass and gain weight as they get older. However, type 2 diabetes is increasing significantly among children, adolescents and young people.
Introduction to diabetes. Prediabetes is a condition in which your blood sugar level is higher than normal, but not high enough to be labeled as diabetes. If left untreated,
