Most Alzheimer’s patients are elderly people, and by nature Alzheimer’s itself does not lead to swollen feet. If Alzheimer’s patients have swollen feet, there should be the following reasons: 1, drug reasons: patients with Alzheimer’s disease will eat a variety of drugs, first look at the side effects of drugs that do not cause swollen feet, remove the drugs that cause swollen feet side effects; 2, cardiac insufficiency: such as heart failure; 3, abnormal kidney function; 4, poor venous reflux in the lower extremities, elderly people with swollen feet can be pressed by hand on the ankle to determine whether it is concave or non-concave. If there are pits under pressure, it is generally concave edema. If the swollen feet of the elderly worsen after one day of activity and decrease after rest, it is considered that the venous reflux of the lower extremities may be poor, so we should consult the vascular surgery department for the next step of treatment, and we can wear elastic stockings to reduce the venous reflux of the lower extremities and reduce the swollen feet.
