Why HbA1c Below 7% May Not Mean Diabetes Control
HbA1c is a number doctors use to look at blood sugar control.
A result below 7% is often considered a treatment goal for people with diabetes.
But this number is only one part of the picture.
Two people can have the same HbA1c result and still have different blood sugar experiences.
One person may have frequent blood sugar spikes.
Another may have episodes of blood sugar that is too low.
That means a good-looking HbA1c result does not always mean blood sugar is steady.
Doctors say other parts of a person’s glucose pattern also matter.
An HbA1c below 7% is often viewed as a common diabetes treatment goal.
Doctors say HbA1c alone does not show the complete picture of blood sugar control.
People with the same HbA1c can experience very different glucose patterns.
Some may have frequent blood sugar spikes despite a similar HbA1c result.
Others may experience episodes of hypoglycaemia, or unusually low blood sugar.
- Who
- People living with diabetes and their doctors.
- What
- Doctors say an HbA1c below 7% does not always mean diabetes is fully under control.
- Why
- Because HbA1c alone may not reveal blood sugar spikes or episodes of hypoglycaemia.
- Common treatment goal
- An HbA1c below 7% is often considered a goal for many people with diabetes.
- Main limitation
- HbA1c alone does not show the complete story of blood sugar control.
- Different experiences
- Two people can have the same HbA1c while experiencing different blood sugar levels.
- Possible issue
- Frequent glucose spikes may occur despite an HbA1c below 7%.
- Another possible issue
- Episodes of hypoglycaemia may occur even when HbA1c results are similar.
