Each year in the U.S. diabetes results in the amputation of about 65,700 legs or feet. About 85% of those began with a diabetic foot ulcer. And for Dr. David Schwegman, the mission to educate people about the issue is personal.
His father, a diabetic, had a foot ulcer that resulted in the amputation of his left leg, which contributed to his death, his son said.
"He became a statistic," Schwegman said. "He was one of the 50% of people that died within five years after having an amputation."
The meta-analysis included data from eight observational cohort studies and 11 randomized controlled trials that involved diabetes and measuring vitamin D. The investigators, who were from Tufts Medical Center and Carney Hospital in Massachusetts, found that overall, individuals who consumed more than 500 International Units (IUs) per day of vitamin D had a 13 percent reduced risk of type 2 diabetes when compared with those who consumed less than 200 IU per day.
