Patients with type 2 diabetes mellitus who quit smoking see a temporary deterioration in glycemic control that may last up to three years, according to a recent study published in The Lancet Diabetes & Endocrinology.
Researchers led by Deborah Lycett, PhD, of Convetry University studied primary care records of 10,692 adult smokers with type 2 diabetes mellitus over six years to see if there was any association between diabetes control and smoking cessation.
They found that in 3,131 people (29 percent) who had quit for at least one year, HbA1c increased by 2.3 mmol/mol before gradually decreasing as abstinence continued.
During the same amount of time, 5,831 (55 percent) of patients who continually smoked experienced a more gradual increase in HbA1c. Those who quit saw comparable HbA1c levels with continual smokers after three years of quitting.
“Knowing that deterioration in blood glucose control occurs around the time of stopping smoking helps to prepare those with diabetes and their clinicians to be proactive in tightening their glycemic control during this time,” Dr. Lycett concluded.
Sufferers of type 2 diabetes mellitus (T2DM) who quit smoking are likely to see a temporary deterioration in their glycaemic control which could last up to three years
