Neuropatías en el embarazo

Neuropathies in pregnancy, although not very frequent, do generate a great impact on the quality of life when diagnosis and timely treatment are not established. There are several physiopathological mechanisms such as those of mechanical, hormonal and immunological origin. The location of the neuronal lesion will depend on the mechanism and therefore has a direct relationship with the trimester of pregnancy. Thus, the neuropathies of hormonal and mechanical origin associated with pregnancy, such as the carpal tunnel that is the most frequent, occur more in the second and third trimesters, while those of strict mechanical appearance such as those involving the lower limbs, They occur especially during childbirth. Other neuropathies such as cranial neuropathies are infrequent and oblige to rule out secondary etiologies. Polyneuropathies, more than being related to pregnancy, are precipitated or can be expressed during this condition. The following narrative review describes the most common neuropathies during pregnancy according to location, symptomatology, clinical findings, trimester of onset and presumed pathophysiological origin.
