What is Diabetic Foot Ulcer? Why Does it Happen?

Diabetic foot ulcers are usually caused due to uncontrolled Type 1 or Type 2 Diabetes. Roughly 15% of diabetics worldwide suffer from diabetic foot ulcers. Ulcers develop due to any trivial injury breaking the integrity of the skin, exposing the layers underneath.

 

Symptoms of Diabetic Foot Ulcer

Before a visual diagnosis by a doctor confirms the presence of a diabetic foot ulcer, there are a few symptoms that are noticeable at home.

  • Discharge of fluid, blood or pus
  • Skin Changes
  • Skin discolouration
  • Pain
  • Altered sensation
  • Odour

 

Causes Of Diabetic Foot

Understanding the causes of a diabetic foot can help prevent foot ulcers:

 

1. Diabetic Neuropathy

  • Excessive thirst or hunger
  • Unexplained tiredness and fatigue
  • Frequent urination
  • Weight loss
  • Severe diaper rash in babies (maybe due to diabetes)

 

2. Sensory Neuropathy

In the long run, the sensory nerves of a diabetic person suffer damage. So, they do not feel heat, cold, or pain in their feet.

 

3. Peripheral Neuropathy

Muscle weakness and loss of reflexes, especially at the ankle caused by peripheral neuropathy. This changes the walking pattern and leads to foot anomalies increasing the risk of injury. 

 

4. Peripheral Artery Disease

Diabetes damages blood vessels by hardening and narrowing the arteries. The damage restricts blood supply to the feet and increases the risk of an ulcer infection.

 

Risk Factors of Diabetic Foot Ulcer

The pathophysiology of diabetic foot ulcers shows a correlation between the following factors and foot ulcers:

 

Treatment for Diabetic Foot Ulcers

The treatment of non-healing diabetic ulcers can vary from medications to surgical treatment. Even before the treatment for the diabetic foot ulcer begins, it is imperative to get the blood glucose levels under control. Without proper control of diabetes, diabetic foot ulcer treatment will be ineffective.

Medication For Diabetic Foot Ulcer

The foremost objective in managing foot ulcers in diabetes is to heal the ulcer before it gets infected. Diabetic foot ulcer treatment needs antibiotics. 

 

To prevent infection, cleanse the wound of debris. To enhance the healing process, before dressing, topical medication should be applied.

 

Surgical Procedure For Diabetic Foot Ulcer

When conservative treatment fails, your doctor may suggest a surgical procedure. Surgical management includes the excision of bones, correction of deformities and amputation when tissue damage is irreversible.

 

Prevention of Diabetic Foot Ulcer

The ideal way to treat a diabetic foot ulcer is to prevent its formation in the first place. 

  • Learning how to examine your feet is vital in determining a potential problem in the early phase. Carefully inspect your feet every day.
  • Wearing the right size shoes and socks will go a long way in lowering risks. 
  • Have a regular check on blood sugar and blood pressure levels. 
  • Avoid other predisposing risk factors like smoking and alcohol consumption.

 

When to See a Doctor?

  • Once you notice a foot wound, ulcer or foul-smelling discharge coming from an open sore, seek the help of your diabetologist immediately.
  • Diagnosis and treatment in the initial phase would result in faster healing with a good prognosis.
