During the 1980s, the Diabetes Control & Complications Trial (DCCT)
began, seeking to determine whether intensive blood sugar control would help reduce long-term complications such as vision loss, kidney failure, nerve damage, and heart disease. According to Dr. David M. Nathan
, director, Diabetes Center at Massachusetts General Hospital, tighter diabetes control can reduce these risks by as much as 60-70 percent. In addition, a study published in JAMA
revealed that type 1 diabetes patients who have undergone intensive therapy early on successfully reduced the risk of mortality by 33 percent.
