Risk Factors
Anatomical Factor & Body Fluid Balance Changes
There are several factors [5] that are associated with the development of carpal tunnel syndrome. While these factors by themselves, are not capable of causing the disease, these factors can increase your chances of developing or aggravating damage to the median nerve.
Unusual pressure [6] on the median nerve may be produced by a wrist fracture or dislocation that affects the space inside the carpal tunnel. It could be more likely that people with narrower carpal tunnels could easily develop carpal tunnel syndrome.
Fluid retention [7], which is normal during pregnancy, may increase the pressure in the narrow space of the carpal tunnel, irritating or damaging the median nerve. After birth, pregnancy-associated carpal tunnel syndrome [8] typically recovers naturally.
