Most diabetics are advised to file down their toenails to the desired length, but Dr. Shakula says pedicurists can trim them with care as long as the nails are not misshapen or excessively thickened. And never use a drill on the feet. Do not, however, trim or push back the cuticles, warns Dr. Albreski. Remember, diabetics are more prone to bacterial and fungal infections of the skin and nail. Once present, these types of infections take longer to heal and are more likely to spread and cause a serious health problem.
Poor circulation can also cause problems with healing.
Normally, the body keeps a steady supply of fresh blood flowing to heal damaged tissues. Poor circulation means a poor flow of blood, which slows healing. Even a small cut or ingrown nail may take a long time to heal, which increases the likelihood of an infection. However, the spaces between the toes typically trap moisture, regardless of how dry the rest of the foot is. Applying a cream or lotion between the toes only traps more moisture and may cause the skin to break down, which in turn invites infection.
