Long-term blood sugar (HbA1c) – what do your numbers mean?
Have you had your Long-term blood sugar (HbA1c) level measured and are unsure what the numbers mean? Here you will find a clear explanation of the normal range, what a level that is too high or too low can mean, and when it makes sense to get tested.
What is the normal range for Long-term blood sugar (HbA1c)?
What is the normal range for Long-term blood sugar (HbA1c)?
Long-term blood sugar, also known as HbA1c, is used to assess blood sugar regulation over the past 2-3 months. The normal reference interval for HbA1c generally ranges between 31-44 mmol/mol. For people with diabetes, values below 48 mmol/mol are aimed for, while values between 48-53 mmol/mol may be acceptable depending on individual circumstances. For frail elderly and demented individuals, values between 53-70 mmol/mol may be appropriate. The variation depends on factors such as age, gender, and laboratory methods. Being close to the limit values can indicate a risk of complications or a need for treatment adjustment.
What does a low level mean?
A low level of HbA1c, typically below 31 mmol/mol, can indicate hypoglycemia, which is associated with low blood sugar. Symptoms may include sweating, trembling, confusion, and in severe cases, unconsciousness. Common causes include overdose of insulin or other diabetes medications, insufficient food intake, or intense physical activity. Particularly vulnerable groups are people with diabetes who are undergoing intensive treatment, or elderly people with reduced appetite. It is important to consult a doctor to adjust treatment and avoid further episodes.
What does a high level mean?
A high level of HbA1c, above 48 mmol/mol, indicates poor blood sugar control and may be a sign of diabetes or a risk of complications such as cardiovascular disease, kidney damage, and nerve problems. Symptoms may include increased thirst, frequent urination, and fatigue. Causes can be insufficient medication, poor diet, or lack of physical activity. People with persistently high levels should seek medical attention to adjust their treatment and prevent serious complications.
