The most obvious signs of diabetes include the following:

? Frequent thirst (polydipsia)

? Constant urination (polyuria)

? Rapid loss of weight

? Unusual hunger

? Obvious weakness and fatigue

How is it Diagnosed?

There are many methods by which diabetes is diagnosed, but doctors commonly use the following approaches:

? Health screening

? Detection of hyperglycemia

? New signs and symptoms attributable to diabetes

Diagnosis is often prompted with the onset of the symptoms. Patients often undergo a diabetes screening test, the particulars of which often vary according to circumstances and local policy. Some may be made to undergo random glucose testing, fasting glucose and insulin, or glucose two hours after 75g of glucose. Sometimes, doctors diagnose the disease through a formal glucose tolerance test.

For adults aged 40-50, health caregivers recognize universal screening tests for diabetes with earlier screening tests for those with potential risk factors, such as obesity, family history of diabetes, and high risk ethnicity (Hispanic, American Indian, African, American, Pacific Island, and South Asian).

What are the Risk Factors?

There are many risk factors that, when combined, could increase the probability scale in developing diabetes. However, the real cause of the disease remains unknown. Below are a few of the most common risk factors associated with diabetes:

? Obesity ? One of the strongest risk factors identified for diabetes is being overweight. Most cases of Type 2 diabetes have a Body Mass Index (BMI) that is greater than the normal 25, which led scientists to conclude that weight plays a significant role in preventing the onset of the symptoms.

? Waist Size ? Another factor that is somewhat related to obesity is waist size. In fact, research shows that waistline may be a better predicator of diabetes risk. People who have the so-called ?apple-shaped? figure (much of their weight is in the waist and upper abdomen) are more likely to develop diabetes than persons with larger hips, buttocks, and thighs (or the ?pear-shaped? figure).

? Sedentary Lifestyle ? Exercise correlates with weight and waist circumference. As such, lack of adequate exercise is also a risk factor for diabetes.

? Age ? Although some types of diabetes occur even in children, the risk for diabetes increases as the person's age also increases. The average age of persons diagnosed with diabetes is 40 years.

? Background ? This includes family history and ethnic background. Scientists have yet to discover a direct hereditary pattern for diabetes, but several studies show that you have a greater risk of developing the disease if you have a family member diagnosed with diabetes. As for ethnicity, diabetes is found to be more common among African-Americans, Hispanics, Native Americans, Asians, and Pacific Islanders.

How Can You Prevent it?

Knowing what are the risk factors involved in diabetes is already the first step to its prevention. However, knowing is different from doing. You may know a lot about the disease now but if you do not use this new knowledge you garnered in order to protect yourself from the ravages of diabetes, then that knowledge is useless. Now, therefore, is the time for you to take action ? do something.

The good news is that the most common type of diabetes, Type 2, is easily manageable by maintaining a proper diet and exercising regularly. The Diabetes Prevention Program, a study conducted by the American Diabetes Association, has just been completed and the findings showed that people with pre-diabetes (those that exhibit the risk factors as well as increased blood sugar levels in the blood but without the actual onset of the disease) can prevent the development of Type 2 diabetes through diet change and exercise. Proponents say that the patients? blood glucose levels may even return to normal as a result of proper diet and regular exercise.

The study also showed that medications can significantly delay the development of diabetes. However, diet and exercise worked better in preventing the full onset of the symptoms.

The American Diabetes Association recommends 30 minutes a day of moderate physical activity, coupled with a five to ten percent reduction in body weight.
