People with foot and ankle problems tend to weigh more than people who don't, suggesting that the extra weight may be bad for the feet, according to survey findings released in the July 21 Reuters Health.  Among more than 6,000 people who responded to the survey, those who said they had foot and ankle pain, had undergone foot surgery, or consulted a doctor about foot pain, tended to weigh more than people who did not report similar problems.
