What can cause carcopenia with aging?

ANSWER

Although sarcopenia is seen mostly in people who are inactive, the fact that it also happens to people who stay physically active suggests there are other things that cause it. Researchers believe these include:

  • Fewer nerve cells are responsible for sending signals from the brain to the muscles
  • Lower concentrations of some hormones, including growth hormone, testosterone, and insulin-like growth factor
  • Less ability to turn protein into energy
  • Not enough calories or protein each day to keep muscle mass
