During pregnancy, fluid retention in the body can lead to pressure on the median nerve within the carpal tunnel. This condition causes symptoms such as numbness, pain, and tingling in the hand and fingers. Carpal tunnel syndrome is quite common in pregnant women, affecting approximately one in three pregnancies. Symptoms usually resolve spontaneously after childbirth. For pregnant women experiencing severe symptoms, treatment options include avoiding strenuous movements of the hand and wrist, using a resting splint, managing weight by controlling salt and water intake, and performing specific wrist exercises.
