If you have a foot amputation to get rid of gangrene, will you later need a leg amputation?

You should not: Predicting a more proximal leg amputation depends on how well the 1st amputation level was determined to optmize healing & function, aggressive treatment of the cause of amputation (control diabetes, resolve infection, maintain or improving blood flow, stop smoking, normalize cholesterol & triglycerides ) and early identifcation of any new problem. Continued follow up with you doctor is mandatory.

Maybe: Depending on whether the factors that led to the gangrene are well controlled may determine whether you have more progression of disease, and eventually need a higher amputation. Not smoking, controlling diabetes tightly, controlling cholesterol, wearing proper shoewear, and exercising, are all things you can do to decrease your risk of a second surgery.

It is possible.: Sometime people go on to have a higher level amputation if the infection is not controlled or if the circulation is not adequate for healing to take place.
