A foot ulcer is a breakdown of the skin that exposes the underlying tissue. It can range from a shallow red sore to a deep wound that may expose the bones or tendons. The ulcer can be caused from pressure, friction, trauma or inadequate blood flow due to Peripheral Artery Disease (PAD). In diabetic patients, it can easily go unnoticed due to reduced pain sensation, which can lead to further complications.
Diabetic foot ulcer complications:
- Infection:
Foot ulcers are nothing but open wounds, they can easily become infected and the infection may spread to soft tissues, bones or even bloodstream, which can be fatal if left untreated.
- Gangrene (tissue death):
If the blood flow to the ulcer area is severely reduced, tissue death can occur, this can even lead to the amputation of the affected area to prevent the spread of infection.
- Amputation:
In certain cases when the ulcer doesn’t heal or if it becomes critically infected, partial or full foot amputation might be necessary.
- Chronic wounds:
Non-healing ulcers can become chronic, leading to constant pain, limited mobility and decreased quality of life.
- Bone infection:
If the infection spreads to the bone, it can cause long term issues which requires aggressive treatment, including surgery.
Why do diabetic patients develop foot ulcer?
- Peripheral neuropathy:
Diabetic neuropathy is one of the primary reasons for foot ulcer in people with diabetes. When nerves are damages, the patient may lose the ability to feel pain, heat or cold. As a result, minor cuts, blisters or injuries can often go unnoticed. Since the sense of pain is lost, the patients may continue to put pressure on the injured area, worsening the wound. Neuropathy can also lead to muscle weakness and imbalance in feet which can cause deformities. These deformities apply pressure on certain parts of foot making it prone to foot ulcer. Autonomic neuropathy, this can affect the nerves of the foot, reducing its ability to sweat. Without normal sweating, skin can become dry and cracked, providing an entry point for infections.
- Peripheral Artery Disease (PAD):
PAD is a condition where the blood vessels in the legs and feet become narrowed due to the build-up of fatty deposits in the arteries. People with diabetes are at a higher risk of developing PAD. Since the blood circulation to the foot is reduced, the oxygen supply is also reduced, impairing the ability to heal. This can increase the chance of developing foot ulcer.
- Hyper-glycemia (high blood sugar):
Overtime, diabetes can cause the blood vessels to thicken, which restricts the delivery of essential nutrients and oxygen to skin, hindering the body’s ability to heal minor injuries causing infections. It may also affect the immune system, making it harder to fight off infections.
- Pressure and trauma:
Foot ulcers in diabetics are often caused by repeated trauma or pressure to the skin. This can happen due to several reasons which includes wearing ill-fitted shoes, which can cause friction or excessive pressure in the same point of the skin, leading to blisters, corns or calluses. These minor injuries might go unnoticed, causing ulcers.
- Calluses:
People with diabetes are more likely to develop calluses (thickened areas of skin) on the bottom of the feet due to neuropathy and abnormal foot pressure. These can build up and cause extra pressure eventually leading to skin breakdown and ulceration.
- Foot deformities:
Diabetes can cause Charcot foot, a condition where the bones of the feet weaken and shift due to poor circulation, nerve damage and trauma. This can make the shape of the foot abnormal, increasing pressure points leading to ulceration.
Foot Ulcer Treatment:
The wound is cleaned regularly to remove tissue and prevent infections. After cleaning, it is dressed to keep the wound moist and protected, which promotes healing. After dressing, the foot is offloaded by reducing the pressure on the wound using specialized shoes or braces.
- Infection control:
If the ulcer becomes infected, antibiotics are prescribed to be consumed orally. Sometimes, antimicrobials are used on the wound to combat infections.
- Blood sugar control:
Controlling blood sugar levels through medication, diet and exercises can promote healing and prevents new ulcers from forming.
- Improving circulation:
For patients with poor circulation, procedures like angioplasty or bypass surgery may be recommended to restore blood flow to that area.
- Advanced therapies:
In some cases of chronic non-healing ulcers, doctors might use growth factors to accelerate the skin’s healing process.
- Surgical intervention:
Removing dead or infected tissue is a key part of ulcer treatment. In some extreme cases where ulcers cannot heal and infection spreads, partial or full amputation of foot may be necessary
Early and aggressive treatment is essential to promote healing and prevent serious complications like infections or amputations.
