Most foot ulcers are found under the big toes or the balls of the feet. Foot ulcers can affect the skin at the bottom of the foot down to the inner bones. If it is not timely treated, the patient could be infected and could lead to lower-extremity amputations.

Causes of diabetic foot ulcers

Every patient with diabetes has a higher risk of developing foot ulcers. There are several factors that could lead to foot ulcers.

  • Poor circulation of blood could lead to foot ulcers. It can also make it difficult for the ulcer to heal. Vascular disease can lead to poor circulation of blood to the foot.
  • Patients with diabetes can develop neuropathy. Neuropathy is the inability to feel pain in the feet due to nerve damage caused by an increased level of blood sugar. This condition could lead to foot ulcer. High glucose levels can slow down the healing process of the foot ulcers which could lead to infection.

Other causes of foot ulcers include:

  • Foot deformities
  • Irritation
  • Trauma 

Risk factors for developing foot ulcers

The most well-known risk factors that cause foot ulcers include diabetic neuropathy, auxiliary foot disfigurement, and peripheral arterial occlusive disease. A cautious physical examination, followed by monofilament testing for neuropathy and non-invasive testing for blood vessel inadequacy, can identify patients susceptible to foot ulcers, and also identify patients who already have ulcers or other diabetic foot diseases.

Proper education regarding foot hygiene, nail care and footwear are significant so as to reduce the risk of sustaining an injury that could lead to the formation of foot ulcers. Diabetic foot complexities are the most widely recognized reason for non-traumatic lower extremity amputations. The risk of lower extremity amputations is 15 to 46 times higher in diabetic patients than in people who don’t have diabetes mellitus.

The risk factors of diabetic foot ulcers include:

  • Race – African-Americans, native Americans and Hispanics are at higher risk of developing diabetic foot ulcers.
  • Age – Aging adults, especially older men are at higher risk of developing diabetic foot ulcers.

Treatment of diabetic foot ulcer

The appropriate treatment methods for Diabetic foot and wound care include:

Managing blood glucose and other related health problems

Keep your blood glucose under control and ensure that you treat every health condition as early as possible.

Preventing the ulcer from getting infected

Taking pressure off the area (Off-loading)

Take pressure off your feet by sitting or lying down. Taking pressure off your foot helps to lessen the stress exerted on the affected foot. When the pressure is too much on the foot, it can make the ulcer expand and lead to infection. If you are overweight, it is recommended that you take necessary measures to lose excess weight. Also, do not stand on your feet for a long period of time.

Debridement is the removal of dead skin tissue from the surface of the wound. Removing the dead skin and other foreign substances helps to prevent infection and allows for a faster healing process.

Applying medication and dressing the ulcer

After the dead skin tissue is removed, the wound will be cleaned and the necessary medications will be applied before it will be dressed and bandaged.

You may be given antibiotics, anti-platelets, or anti-clotting medications to prevent infection and facilitate the healing process.

You may also need to apply over-the-counter medications and creams such as silver sulphadiazine cream, polyhexamethylene biguanide gel or solutions, iodine, and medical-grade honey in ointment or gel form.


Surgery is the last resort when all other conservative treatment methods have failed. You may undergo surgery to take pressure off the affected area like shaving down the bone or removing foot deformities such as hammertoes, bunions, or bumps. 

In extreme cases where the ulcer has gotten infected and refused to heal, your doctor may suggest amputation to prevent the infection from spreading to other parts of the body.
