NORMAL or DANGEROUS    Type Your Blood sugar Level:    mg/dl

Blood sugar level over 400mg/dl is classified as severe diabetes. It is a condition which seeks immediate treatment.

Among the classic symptoms of diabetes, such as fatigue, increased thirst, increased urination, fatigue, blurred vision, drowsiness etc, these levels of blood sugar can develop two serious, life-threatening complications such are DKA (diabetic ketoacidosis) and HHS (hyperosmolar hyperglycemic state).

The treatment of such hyperglycemia is immediate rehydration and administration of rapid insulin in order to lower the levels of glucose as soon as possible.

Prevention includes lifestyle changes, drinking water and continuous measurement of blood glucose and ketones in the urine.

Most of the times, blood sugar level over 400 mg/dl is due to uncontrolled diabetes, in people who are unaware that suffer from diabetes.

But, blood glucose level over 400 mg/dl can also be due to extreme stress or intake of certain medications.


Blood sugar level over 400 mg/dl - Prevention.

Patients who have experienced blood sugar level over 400 mg/dl should drink plenty of water, check their urine for ketones and talk to their doctor to take precautions in order to prevent a further increase of the blood sugar level.

The lifestyle changes are very important. The following lifestyle changes will help keep blood glucose within the normal range:


1.    Eating a healthy diet - this means cutting off fat and caloric foods, and eating fiber-rich foods instead, such as legumes, whole grain products, all kind of vegetables and fruits.

2.    Weight loss - Losing weight lowers your glucose levels. A loss of only 7 % of your total body weight significantly decreases glucose levels.

3.    Exercising - Exercising not only lowers your glucose levels, but it also improves blood circulation and lowers fats in the bloodstream. Exercise at least 45-60 min every day. Consider brisk walking, bike riding, swimming laps, playing your favorite sport etc. DO NOT exercise if you have ketones in the urine.

4.    Quitting smoking and alcohol
