Borderline, or prediabetes, is a condition defined by the presence high blood sugar and predisposition to the disease. According the the American Heart Association, borderline diabetes is determined by higher than normal levels on impaired fasting glucose or impaired glucose tolerance tests. Nearly 60 million adults in the United States have borderline diabetes, a risk factor that doubles the likelihood of developing heart disease. This is a serious medical condition that can be controlled by diet, exercise and making healthy lifestyle choices.
Thirst
For the borderline diabetic, excessive thirst is often one of the first symptoms they experience. Insatiable thirst, is defined by the Medline Plus Medical Encyclopedia as the increased need for fluid intake that is not satisfied despite attempts to curb it. In borderline diabetics, this can be a clear indication that blood sugar is a problem. The levels of blood sugar have surged too high, resulting in a condition called hyperglycemia. With the increased fluid intake, so too is the need to urinate more frequently.
Hunger
Insatiable hunger is also a symptom of borderline diabetes. In borderline diabetics, the impairments to blood sugar processing can trigger this response. When the hunger is satisfied, the body floods with glucose. When the hunger is not satisfied, it can lead to intolerance and unintentional weight loss. Peace Health defines a positive score on the hemoglobin A1c test as ranging between 5.7 percent and 6.4 percent while the fasting blood glucose score between 100 to 125 mg./dl and the oral glucose tolerance test score between 140 and 199 mg./dl. after two hours.
Blurred Vision
Blurred, or a change in vision could be indicative of prediabetes. The United Project suggests that if an individual suspects blurred vision, to visit a licensed health professional or opthalmalogist to get a diagnosis. The treating physician may collect information on other medical problems, medications currently being taken; and ask about headaches, allergies or colorblindness. Additional tests may include: glaucoma testing, blood tests and urinalysis for glucose. If the physician suspects borderline diabetes, a referral may be made to a specialist in that field.
