There are complications

Another main aspect of treatment is the use of insulin injections. When insulin was developed over years ago, it was lifesaving for many diabetics. And later development of once a day shots was initially perceived as a great advantage.
Though the daily injections are more convenient, there is some concern about possible long-term complications, such as hardening of the arteries. Thus, some physicans are recommending more frequent injections of short-acting insulin to control the blood sugar more tightly during the course of the day. Several recent developments have made this not only possible but also practical. Because of the complications, many diabetics have considered natural cures for diabetes and other serious illnesses.
