The condition of prediabetes can be determined in one of three ways based on a blood sample. A fasting plasma glucose test that reads between 100 to 125 is considered prediabetic. Scoring between a 149 to 200 blood sugar following an oral glucose tolerance test is within the prediabetic range, according to WebMD.
The third method is a three to four month average of blood sugar levels called a Hemoglobin A1C test. The prediabetic range for this long-term test is an average of 5.7 to 6.4 percent blood sugar.
Prediabetes affects 79 million Americans, putting them at increased risk for diabetes, heart disease and strokes, reports WebMD. The condition is characterized by a lack of insulin being absorbed by the body due to slowed production/absorption rates by the body. The condition can be improved significantly by adhering to a regimen of weight loss, nutrition and exercise.
Obesity is causally linked with diabetes, so even a reduction in weight by 5 to 10 percent could reduce full diabetes onset, says WebMD. Moderate exercise can prevent and manage diabetes, and strengthen key organs such as the heart; 30 minutes a day is sufficient to achieve this effect. Food is a key factor to preventing further complications and improving health. Eating low-fat proteins, vegetables and whole grains provide for optimum health. Avoid sugary and starchy carbohydrate-heavy foods.
