Blood Sugar Level Chart

Blood glucose refers to the amount of glucose present in the human blood. The normal glucose level should range between 70 to 99mg/dl at early morning in empty stomach. The level gradually varies after consumption of food. Outside the normal blood sugar level is treated as a medical condition, which is referred as Diabetes mellitus. Here in this blood sugar level chart we have provided the blood glucose level in terms of mg/dl under three categories: normal, per-diabetics and post-diabetics.
