is elevated blood sugar thicker
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.
