Borderline diabetes is not a type of diabetes, but can be a precursor to the condition. Borderline diabetes is essentially an impaired glucose tolerance, which occurs when the blood sugar levels are above normal but short of the diabetic cut-off range. The symptoms can potentially indicate type 1 or type 2 diabetes. Severe symptoms tend to be similar to type 1 diabetes; commonly including: thirst, excessive urination, tiredness/general weakness, diabetic coma, increased hunger and unexplained weight loss. Although borderline diabetes is not classed as diabetes the risk of developing other diabetic complications such as coronary heart disease is equal to that of any patient in the diabetic category. It is therefore recommended that they adopt the lifestyle changes advised for diabetics, and keep in regular contact with their doctor.
