Factors that may increase your risk of muscle cramps include:

  • Age. Older people lose muscle mass, so the remaining muscle may get overstressed more easily. This may increase the risk for muscle cramps.
  • Dehydration. Athletes who become fatigued and dehydrated while participating in warm-weather sports frequently develop muscle cramps.
  • Pregnancy. Muscle cramps also are more common during pregnancy.
  • Medical conditions. You may be at higher risk of muscle cramps if you have diabetes, or nerve, liver or thyroid disorders.
