Peripheral Neuropathy:
Diabetes can cause nerve damage, known as peripheral neuropathy, which reduces sensation in the feet. This makes it difficult to notice small injuries, like cuts or blisters, until they become more severe.
Poor Circulation:
Diabetes can also cause poor blood circulation, particularly in the feet. Reduced blood flow slows down the healing process, making it harder for wounds to recover and more likely to become infected.
Impaired Immune System:
High blood sugar levels can weaken the immune system, making it harder for the body to fight off infections. This increases the risk that a minor foot sore could develop into a more serious problem.
Common Causes of Foot Sores in Diabetic Patients
Pressure Areas:
Poorly fitting shoes or socks can create pressure points on the feet, leading to blisters, calluses, or sores.
Injuries:
Small injuries, such as cuts, scrapes, or punctures, can happen easily and may go unnoticed due to reduced sensation in the feet.
Dry Skin:
Diabetes can cause the skin on the feet to become dry and cracked, increasing the risk of sores and infections.
Foot Deformities:
Conditions like bunions and hammertoes are more common in people with diabetes, can lead to areas of excessive pressure, resulting in sores.
Symptoms to Watch For
Redness or Swelling:
Early signs of a developing sore may include redness or swelling, particularly over lumps or bumps like joints, heels or toes, or on areas of injury.
Weeping sores:
If you notice any unusual discharge on your socks or inside your shoes, this could indicate a sore or ulcer that needs attention. Wearing white socks can help you catch this early and get it healed before it becomes a bigger problem.
Visible Wounds:
Any open wound, blister, or ulcer on the foot, no matter how small, should be treated with care to prevent it from worsening. Keeping it clean and dry, and using a sterile bandaid to cover it, is best, If it hasn’t healed after 1 week, then see your medical professional or local podiatrist.
Pain or Discomfort:
While some individuals may not feel pain, others may experience discomfort around a sore or ulcer. Persistent foot pain should be evaluated by a podiatrist.
Prevention and Care of Foot Sores
Daily Foot Inspections:
Check your feet daily for any signs of sores, blisters, or other abnormalities. Ensure you inspect between your toes and on the soles of your feet.
Proper Footwear:
Wear shoes that fit well and provide adequate support to prevent foot sores. Avoid walking barefoot, to reduce the risk of injury.
Moisturise Regularly:
Keep your feet moisturised to prevent dry, cracked skin, but avoid applying lotion between the toes to reduce the risk of fungal infections. Using urea based cream is the best for dry thickened skin on the feet.
Trim Nails Carefully
Cut your toenails straight across to avoid ingrown nails, which can lead to sores. If you have difficulty reaching your feet, seek professional help from a podiatrist.
Seek Help Early
If you notice any signs of a sore or infection, seek a podiatrists advice immediately. Early intervention can prevent the condition from worsening and may avoid more serious complications.
