There are several possibilities for foot swelling after cerebral hemorrhage: first, deep vein thrombosis. Patients with cerebral hemorrhage need to rest in bed while the affected limb is paralyzed and cannot move. If there is no passive activity for a long time, or if family members help massage to promote blood circulation, deep vein thrombosis in the lower limbs may occur. This creates an obstruction to blood return to the distal end, resulting in significant edema. There is usually increased skin tone and bruising, and the skin temperature will be elevated. Second, hypoproteinemia. The poor nutritional status of patients after cerebral hemorrhage often leads to hypoproteinemia if they do not eat enough protein, causing generalized edema, which is most obvious in the low hanging parts of the lower limbs. Thirdly, edema of the paralyzed limb, because of reduced activity and impaired blood return, even without hypoproteinemia and deep vein thrombosis of the lower limb, edema is often produced. This is also related to the autonomic nerve damage of the limb, which generally requires elevation of the affected limb so that it is slightly above the heart position.
