WESTFIELD - Joe Gligora has diabetes, just like 25.8 million other Americans. He was persuaded to come to the new Diabetes Education Program at Westfield Memorial Hospital. Gligora had been reluctant to attend the program, because he thought he would have to make difficult changes in his life. But he worked together with Kim Greiner, registered dietician and certified diabetes educator, to set small, realistic goals. Working toward these goals made a big difference in the way he felt, and his new knowledge empowered him to make healthier choices. The program emphasizes the proper use of insulin as well as better dietary choices.
