Prolonged blood sugar extremes â blood sugar that's either too high or too low for too long â may cause various conditions, all of which can lead to a diabetic coma. 1  Diabetic ketoacidosis. If your muscle cells become starved for energy, your body may respond by breaking down fat stores. 2  Diabetic hyperosmolar syndrome. If your blood sugar level tops 600 milligrams per deciliter (mg/dL), or 33.3 millimoles per liter (mmol/L), the condition is known as diabetic hyperosmolar syndrome. When your blood sugar gets this high, your blood becomes thick and syrupy.
High pre-meal blood sugar levels could indicate a health problem. Whether youâve been diagnosed with diabetes or simply monitor your blood sugar levels to track your health, fasting and postprandial blood glucose levels are frequently measured.ccording to the ADA, fasting blood sugar should fall between 70 to 130 milligrams per deciliter of blood. After you eat, this number should increase as your body absorbs sugar molecules from food. However, the ADA recommends that the postprandial blood glucose level stays at or below 180 milligrams per deciliter.
