Diabetes Warning Signs

Hyperglycemia and Diabetes

In this health topic, we explain the dangers of hyperglycemia, or high blood sugar levels, and diabetes. Hyperglycemia causes many of the warning signs of diabetes listed above. Hyperglycemia may be caused by skipping or forgetting your insulin or diabetes medicine, eating too many grams of carbs for the amount of insulin administered, simply eating too many grams of carbs in general, or from stress or infections.

For more detail, see WebMD's article Hyperglycemia and Diabetes.

Diabetic Coma in Type 2 Diabetes

In this health topic, we discuss hyperglycemic hyperosmolar nonketotic syndrome (HHNS), an extremely serious complication that can lead to diabetic coma and even death in type 2 diabetes. This serious condition occurs when the blood sugar gets too high and the body becomes severely dehydrated. To prevent HHNS and diabetic coma in type 2 diabetes, check your blood sugar regularly as recommended by your health care provider; check your blood sugar more frequently when you are sick, drink plenty of fluids, and watch for signs of dehydration.

For more detail, see WebMD's article Diabetic Coma in Type 2 Diabetes.

Other Warning Signs of Diabetes Complications

Other warning signs of type 2 diabetes' complications may include:

Contact your health care provider right away so you can have a diabetes test if you have any of these diabetes warning signs. Even people with pre-diabetes can have the increased risk of heart disease seen in people with type 1 or type 2 diabetes.
