Quitting smoking briefly deteriorates diabetes control
"Knowing that deterioration in blood glucose control occurs around
the time of quitting smoking helps to prepare those with diabetes and their
clinicians become proactive in tightening their glycaemic control during this
time," said principal investigator Deborah Lycett from Coventry
University.
The research team examined the primary care records of 10,692 adult
smokers with Type-2 diabetes over six years to investigate whether or not
quitting was associated with altered diabetes control.
The study found that in the 3,131 (29 percent) people who quit and
remained abstinent for at least one year, HbA1c which is an average measurement
indicating how well the body is controlling blood glucose levels increased by
2.3mmol/mol (millimoles/moles) or 0.21 percent before decreasing gradually as
abstinence continued.In the same period, 5,831 (55 percent) continual smokers
who did not change their smoking status during the study experienced a more
gradual increase in HbA1c
