As the title indicates, this is the stage before developing diabetes. People in this condition have blood sugar levels significantly above normal. It may be hard to believe, but the statistics show that around a quarter of Americans are at this pre-diabetes stage. It is far from inevitable that someone with pre-diabetes is going to become a diabetic. With changes in diet and exercise, and if necessary, certain medications, it is possible to prevent people with diabetes developing. Given the serious health risks that people with diabetes poses it is well worthwhile to keep a look out for pre-diabetic signs and take the necessary action.

1. Blood sugar levels

These are the prime indicator of whether or not a person has pre-diabetics. The American Diabetes Association (ADA) defines a pre-diabetic as someone with a blood sugar level of 100-125 mg/dl (measured after fasting). Some experts argue that it is possible to detect signs of pre-diabetics even in blood sugar levels below 100 mg/dl. Someone who is overweight or has a history of diabetics in their family should regularly take blood tests. Research proves that overweight people are more at risk and there is also a strong genetic element.
