Disclosed is a method for preventing and treating diabetic gangrenous extremities. A decisive factor of occurrence of diabetic gangrenous extremities is lower limb venous backflow obstruction rather than diabetes. An important adverse factor of frequent lower limb venous backflow obstruction is that lower limb venous blood needs to flow back for more than one meter, which magnifies or even intensifies other adverse factors and makes an original delicate physiological balance difficult to maintain. The important adverse factor is a reality that a person has to face when lower limbs are located in the natural lowest body position. The method for preventing and treating diabetic gangrenous extremities includes temporarily reversing body positions of lower limbs to the highest body position of a human body and implementing exercises so that the vinous blood flows back downwards, original negative factors are temporally converted into positive factors, lower limb venous blood backflow can achieve good effects of upper limb (or even the brain) blood flow, and self-repairing capability of the human body itself can be fully utilized so as to achieve the effect of preventing and treating diseases.
