Frequent numbness and weakness of hands and feet after cesarean section may be caused by postpartum rheumatism, hypocalcemia, local compression and other reasons, which need to be analyzed specifically. 1. postpartum rheumatism: pregnant women who are exposed to cold after delivery are prone to postpartum rheumatism, which manifests the symptoms of numbness of hands and feet. 2. Hypocalcemia: If there is frequent numbness and weakness of hands and feet, it can be considered to be related to hypocalcemia after cesarean section. Calcium ions are involved in many metabolic processes in the body, and hypocalcemia may lead to increased excitability of the local muscles, which will manifest the symptoms of numbness of hands and feet. 3. Localized compression: after cesarean section, women need to rest in bed and cannot move freely, when the limbs are compressed, the blood circulation of the limbs will be blocked, and the symptoms of numbness, pain and weakness of the hands and feet will be manifested as well. If the numbness and weakness of the hands and feet after cesarean section is often unrelieved for a long time, it is necessary to go to the hospital to improve the relevant examination and diagnosis and treatment under the guidance of the doctor.
