Risk Factors for Carpal Tunnel Syndrome

Job tasks that require a combination of repetitive, forceful and awkward or stressed motions of your hands and wrists can put you at risk for carpal tunnel syndrome.

Examples of these include using power tools — such as chippers, grinders, chain saws or jackhammers — and heavy assembly line work, such as occurs in a meatpacking plant.

Although repetitive computer use is commonly assumed to cause carpal tunnel syndrome, the scientific evidence for this association is weak.

Other risk factors include:

  • Sex. Women are three times as likely as men are to develop carpal tunnel syndrome.
  • Certain health conditions, such as:
  • some thyroid problems
  • diabetes
  • obesity and rheumatoid arthritis
  • Women who are pregnant, taking oral contraceptives or going through menopause, due to hormonal changes
  • Fluid retention may be a cause of carpal tunnel syndrome during pregnancy
  • People who smoke cigarettes may experience worse symptoms and slower recovery from carpal tunnel syndrome than nonsmokers do
