What is Diabetic Foot?
The face, being the most exposed part of the body, plays an important role in determining an individual’s beauty and confidence. Unfortunately, facial injuries resulting from accidents or violence can have devastating effects, not only physically but also emotionally.

It occurs when high blood sugar levels damage the nerves and blood vessels in the feet, making it difficult to feel sensations such as pain, heat, or cold.
Causes and Risk Factors
- High blood sugar levels: Uncontrolled diabetes can damage the nerves and blood vessels in the feet.
- Nerve damage (neuropathy): Damaged nerves can make it difficult to feel sensations in the feet.
- Poor blood circulation: Reduced blood flow to the feet can make it harder for wounds to heal.
- Foot deformities: Conditions like hammertoes, bunions, or Charcot foot can increase the risk of foot ulcers.
- Smoking: Smoking can damage blood vessels and reduce blood flow to the feet.
- Kidney disease: People with kidney disease are more likely to develop diabetic foot.
Symptoms
- Foot ulcers: Open sores on the feet that can be painful or painless.
- Infections: Bacterial, fungal, or viral infections can occur in the feet.
- Swollen or red feet: Increased blood flow or infection can cause swelling or redness.
