Frequent Checks Linked to Lower A1Cs

Why do some people with diabetes have good blood glucose control while others struggle with too-high A1Cs? That’s the question researchers hoped to answer when they studied nearly 1,900 adults with type 1 diabetes. Participants were divided into two groups: those whose A1Cs (average blood glucose over the past two to three months) were under 6.5 percent (140 mg/dl estimated average glucose) over the previous year and those whose A1Cs were 8.5 percent (197 mg/dl eAG) or more. The group with well-controlled blood glucose levels checked blood glucose more frequently, tested more often before dosing fast-acting insulin, typically injected mealtime insulin before eating instead of during or after a meal, missed insulin doses less often, and exercised more. For instance, while 72 percent of participants with A1Cs under 6.5 percent checked their blood glucose five or more times a day, only 36 percent of people with poor glucose control tested that often. Despite lower A1Cs, people in the well-controlled group weren’t at any greater risk for severe hypoglycemia (low blood glucose).
