Factors that may increase your risk of stress fractures include:

  • Certain sports. Stress fractures are more common in people who participate in sports such as track and field, basketball, tennis, or gymnastics.
  • Increased activity. Stress fractures often occur in people who suddenly shift from a sedentary lifestyle to an active training regimen — such as a military recruit subjected to intense marching exercises or an athlete who rapidly increases the intensity, duration or frequency of training sessions.
  • Sex. Women who have abnormal or absent menstrual periods are at higher risk of developing stress fractures.
  • Foot problems. People who have flat feet or high, rigid arches are more likely to develop stress fractures.
  • Weakened bones. Conditions such as osteoporosis can weaken your bones and make it easier for stress fractures to occur.
