What causes high HbA1c and low RBC?

High HbA1c and low RBC can be caused by many reasons.

If your HbA1c is in between 4 % and 5.7 % and your RBC is in between 4.5 mil/uL and 5.5 mil/uL then you need not worry as these are the normal ranges for HbA1c and RBC respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Long-term complications of diabetes develop gradually. The longer you have diabetes the higher the risk of complications. Eventually, diabetes complications may be disabling or even life-threatening. Possible complications include:

• Kidney damage
• Eye damage
• Foot damage
• Alzheimer's disease
• Heart and blood vessel disease
