Carpal Tunnel Syndrome: Part 2 - Risk Factors
There are factors associated with a higher risk of developing carpal tunnel syndrome:
Women are at higher risk than men: some suggest that this is due to the smaller cross sectional area of the carpal tunnel; another theory is related to hormonal differences
Older age: some suggest that the changes to the blood supply of the nerve as people age may make the nerve more susceptible to the pressure within the carpal tunnel
Obesity: increased fatty tissue may be responsible by taking up more space within the confined space of the carpal tunnel;
Diabetes mellitus: it is well known that people with diabetes are more at risk for developing peripheral neuropathy – damage to the nerve that reduces its ability to receive sensation information and send signals to our muscles. It is thought that this same metabolic process may make the nerve more susceptible to pressure causing carpal tunnel syndrome. Perhaps the nerve’s threshold for withstanding the pressure is reduced.
Pregnancy: hormonal changes during pregnancy may cause swelling within the carpal tunnel
Occupational risks: repetitive forceful use of the hand, repetitive awkward hand positions and repetitive exposure to vibration – these repetitive stresses may cause swelling that puts pressure on the nerve
