Type 2 diabetes is the most common type of diabetes. Historically, it has occurred mostly in adults, but in the past few decades has increasingly become apparent in children and adolescents. In type 2 diabetes, the body is able to produce insulin but it is either not sufficient or the body is not responding to its effects, leading to a build-up of glucose in the blood.
People with type 2 diabetes may remain unaware of their illness for a long time because symptoms may take years to appear or be recognized, during which time the body is being damaged by excess glucose in the blood stream. Many people are diagnosed only when complications of diabetes become evident.
Similar to type 1, the warning signs are a mix of immediate warning signs as well as more subtle indicators. It is therefore important for people, including the family of possible diabetics to understand what the symptoms are. Some of the symptoms include:
Fortunately, type 2 diabetes can be prevented by taking conscious measures to tackle the risk factors. Self-screening of blood glucose levels periodically can help notify those at risk of their impending condition. In addition, maintaining a healthy weight through a healthy diet, and being physically active can help prevent the onset of diabetes even in persons who have a history of diabetes in the family.
Not all cases of obesity lead to type 2 diabetes but studies have shown consistently that the correlation between the two is very high. In addition, high blood pressure, high-fat and carbohydrate diets, high alcohol intake, smoking and sedentary lifestyles are risk factors to the development of type 2 diabetes.
