Causes & Risk Factors
Narrow carpal tunnel: There are patients who, from an anatomical point of view, have a narrow carpal tunnel. These patients are more likely to develop the syndrome. A typical example is women, in whom carpal tunnel syndrome occurs 3 times more often than men.
Hand strain. Manual workers are affected 3-7 times more often by carpal tunnel syndrome. For example, machine workers, cleaners, and those who work with computers for many hours are typical groups of patients with carpal tunnel syndrome.
Injuries: Wrist Injuries, such as a fracture, can cause carpal tunnel syndrome.
Inflammation: Inflammation of the tendons around the nerve can put pressure on it and lead to the syndrome.
Rheumatoid arthritis: Inflammation of the joints and tendons, which appear in patients with rheumatoid arthritis, causes carpal tunnel syndrome in 50% of them.
Renal failure: Patients undergoing haemodialysis are more likely to develop carpal tunnel syndrome.
Metabolic disorders: Patients with diabetes, hyper or hypothyroidism, obesity, or women during pregnancy are at higher risk for developing carpal tunnel syndrome.
