(CNN) - New Jersey Gov. Chris Christie is in good health, his cardiologist certified Friday.
Thought to be mulling a 2016 Presidential run, Christie’s health has been a constant subplot of discussions around the Republican’s political future.
Up for reelection next month, he is currently far ahead in opinion polls over his Democratic challenger, state Sen. Barbara Buono.
Battling weight problems for years, Christie surprised the political establishment when he revealed in May that he’d undergone lap band surgery three months earlier and had been losing weight since.
Now, Christie appears to be preempting any concerns over his health with the political equivalent of a note from his doctor.
“Governor Christie has normal blood work, normal cardiovascular test results and good functional capacity,” concludes Dr. Rachana Kulkarni.
Kulkarni, who heads the cardiology department at Somerset Medical Center in New Jersey, reports that Christie has been under her care since January 2012.
She last saw the Governor on October 19, an exam Kulkarni calls “unremarkable.” Christie’s blood pressure at the time was 110 over 70 and his heart rate was 68 beats per minute, both well within acceptable norms.
“After he turned 50, Governor Christie has taken a very proactive role in his health,” Kulkarni writes.
“He is aware of being overweight and has taken several measures to address this issue.”
Among Christie’s efforts, Kulkarni certifies, is a healthy diet and regular exercise, doing aerobic and resistance-training exercise four days a week for an hour at a time.
After the February lap band surgery, Christie “has been losing weight steadily,” according to Kulkarni.
“He has been very compliant with his treatment and follow-ups and has taken all the measures towards primary prevention of cardiovascular diseases by aggressive management of his risk factors,” Kulkarni writes.
All this leads to one conclusion.
“Governor Christie has no medical limitations and is fit to serve as the Governor of the state of New Jersey.”
