The numbness of the feet after hospitalization for gastric bleeding may be related to excessive bleeding, causing blood clots and other factors. 1. Excessive bleeding: If the bleeding volume of stomach bleeding patients is relatively large, it may cause low capacitance, resulting in numbness and weakness of limbs due to ischemia of blood vessels in the limbs. 2. cause thrombosis: if the amount of gastric bleeding is relatively large, especially the elderly because of the lack of effective circulating blood volume, easy to cause cardiovascular spasm, once the combination of increased blood lipids, will cause venous thrombosis of the lower extremities, resulting in peripheral circulation disorders, causing numbness of the feet. 3. Other factors: we can not rule out the possibility of other factors, such as peripheral circulation disorders, central nervous system disease and diabetes mellitus, etc., may cause numbness of the feet. Therefore, it is recommended that patients need to go to the regular hospital to receive further examination, according to the cause of the treatment.
