Quitting Smoking Deteriorates Diabetes Control

According to new research, type 2 diabetes patients who quit smoking are likely to see a temporary deterioration in their glycemic control which could last up to three years. They examined the primary care records of 10,692 adult smokers with T2DM over six years to investigate whether or not quitting was associated with altered diabetes control. The study found that in the 3,131 (29%) people who quit and remained abstinent for at least one year, HbA1c increased by 0.21% before decreasing gradually as abstinence continued. — The Lancet April 2015
