Diabetic Foot

What is Numbness/Ulceration and How Does It Relate to Diabetic Feet?

Numbness and ulceration are common complications for people with diabetes, particularly when associated with peripheral neuropathy, a condition caused by damage to the nerves that transmit signals from the spinal cord to various parts of the body, especially the extremities. This damage can lead to a variety of symptoms, including:

Pain
Numbness
Tingling
Burning sensations
Weakness

These sensations typically begin in the feet, making them one of the most affected areas. When the nerves in the feet become damaged, people may lose the ability to sense pain or discomfort, which makes it difficult to detect injuries, cuts, or blisters. This lack of sensation can result in untreated injuries, leading to ulceration or open sores on the feet. Over time, these sores can worsen, potentially leading to infections, which may be harder to manage due to poor circulation and weakened immune response in people with diabetes.

Why is This Dangerous for People with Diabetes?

High blood glucose levels associated with diabetes can damage both the nerves and the blood vessels in the feet, impairing circulation and reducing the body’s ability to heal itself.
Neuropathy (nerve damage) and poor circulation can both contribute to an increased risk of ulcerations, which are open wounds that may not heal well and are more prone to infection.
In severe cases, these infections can lead to the amputation of parts of the foot, ankle, or even the leg if not managed properly.

Common Foot Problems in People with Diabetes

Peripheral neuropathy leading to numbness or loss of sensation in the feet.
Poor circulation making it difficult for wounds to heal.
Dry, cracked skin due to lack of moisture, which can lead to skin damage.
Toe deformities such as hammertoes or bunions, which can increase pressure and lead to sores.
Ulcerations (open sores) on the feet that can get infected.
Infection that may spread rapidly if not caught early.

Treatment/ Assessment of the Diabetic foot

Early detection and management are key to preventing serious foot complications. Here are the essential steps for managing diabetic foot health:

Daily Foot Checks:
- Check your feet daily for swelling, redness, or any changes that seem unusual.
- Look for blisters, cuts, or sores that may go unnoticed due to numbness.
Proper Foot Hygiene:
- Wash your feet daily with lukewarm water and gently dry them, especially between the toes.
- Moisturise dry skin, particularly cracked heels, to prevent fissures and wounds from forming.
Look for Signs of Poor Circulation and Nerve Damage:
- If you notice reduced sensation, altered skin color, or temperature changes, this may indicate issues with circulation or nerve damage.
- Your podiatrist can help assess these symptoms and provide a more detailed examination.
Wear Proper Footwear:
- Always wear shoes or supportive sandals to protect your feet from accidental injury. Avoid walking barefoot, as it increases the risk of injury or infection.
- Proper footwear helps distribute pressure evenly across the foot, reducing the risk of developing ulcers.
Regular Diabetic Foot Screenings:
- Regular visits to a podiatrist for diabetic foot screenings can help detect any problems early before they worsen.
- Podiatrists may check for pressure points, skin integrity, and circulation, providing treatment or advice if needed.

Treatment for Diabetic Wounds and Ulceration

When an ulcer or wound occurs, treatment focuses on several steps to ensure proper healing:

Debridement: This involves removing dead tissue and skin around the wound to promote healing.
Medications and Dressings: The wound is dressed and medicated to prevent infection and keep it clean.
Pressure Relief: Special footwear or braces may be used to relieve pressure on the affected area, helping prevent further damage.
