Foot problems in people with
diabetes are usually treated by keeping blood sugar levels in a target blood sugar range and by using medicine, surgery, and other types of treatment.
When foot problems develop, those problems need
prompt treatment so that serious complications don't develop. Even problems
that seem minor—like calluses, blisters, cracked or peeling skin, and
athlete's foot—need to be checked by a doctor. These
problems frequently occur as a result of reduced sensitivity in the feet and may precede
more serious infections or foot ulcers if the cause (poorly fitted shoes,
excessive weight-bearing, or dry skin) isn't identified and corrected.
After a foot ulcer has formed, it will not heal as long as weight-bearing
on the area continues. Unless your foot ulcer is infected, your doctor may put
a cast on your leg to help the ulcer heal. Keeping your weight off your injured
foot is very important. Even when you are at home, be careful to stay off that
foot. Cushioned shoes, orthotic inserts, support with a cane or crutches, and—in extreme cases—a wheelchair and bed rest may be used to reduce weight and
pressure on the feet. Foot infections need to be treated with antibiotics.
If an ulcer or infection becomes severe and the tissue in the
foot dies (gangrene), one or more of the toes, part or all of the
foot, and sometimes part of the leg may have to be removed (amputated).
Bone and joint deformities can develop on the
feet, such as
toe joint deformities (hammer toe, claw toe, mallet toe) or
Charcot foot. Surgery may sometimes be needed to remove bone that is causing a
All people with diabetes should check their feet regularly for problems. Regular foot exams by health professionals are also important.
