Carpal Tunnel Syndrome Causes

The following are risk factors associated with the development of carpal tunnel syndrome:

• Pregnancy
  
  
• Rheumatoid arthritis and other causes of inflammation of the wrist
  
  
• Endocrine disorders such as diabetes and hypothyroidism
  
  
• Wrist fracture
  
  
• Alcoholism

The relationship between work and carpal tunnel syndrome is unclear. Positions of extreme wrist flexion and extension are known to increase pressures within the carpal canal and apply pressure on the nerve. Intensity, frequency, and duration of work activity and their relationship to carpal tunnel syndrome are unknown. Some specialists believe that activity may contribute to the development of carpal tunnel syndrome to some extent.
