Carpal tunnel syndrome in females: pregnancy and lactation the major risk factors

Background Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy. CTS is more common in the age group of 45-65 years and more common in women than men.  Several factors cause CTS, including pregnancy and lactation.

Methods The study was conducted on 60 females with carpal tunnel syndrome. Each patient was subjected to detailed history and relevant clinical examination with emphasis on elaborate neurological examination. Informed consent regarding participation into the study was taken from the patients. Patients suspected of suffering from carpal tunnel syndrome were subjected to nerve conduction study. Patients were classified into mild- moderate and severe carpal tunnel syndrome according to clinical and nerve conduction grading.

Results Out of 60 females, 21 were pregnant (35%) and 19 were lactating (31.7%).  The mean age of presentation was 44.6±14.14 years with range from 22 to 63 years. Causes were attributed to Pregnancy (35%) lactation (31.7%), hypothyroidism (18.3%), occupational risk factors (15.85%) and gout (2.4%).

Conclusions Carpal tunnel syndrome has a high incidence in females. Sensory symptoms (paresthesia, numbness and nocturnal pain) were more common than symptoms of motor weakness. Dominant hand involvement was more common.
