Diabetes and Foot Health: Prevention, Risks, and Care
Diabetes can have significant effects on the feet due to two prominent complications: diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy results from nerve damage in the legs and feet, reducing the ability to feel heat, cold, or pain. As a result, even a minor cut or sore may go unnoticed and can become infected, leading to ulcers—the main culprit in diabetic foot wounds. Peripheral vascular disease causes reduced blood flow, slowing the healing of sores and cuts and increasing the risk of ulcers and gangrene if wounds do not heal properly.
Common Foot Problems in Diabetics
People with diabetes are more likely to experience foot issues such as athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These problems can lead to infections and severe complications, including amputation. Additionally, neuropathy can also mask the pain of sores and ulcers, making daily self-inspection critical. Risk factors for diabetic foot complications include poor fitting footwear, being overweight, and existing comorbidities such as neuropathy or vascular disease.
Daily Foot Care for Diabetics
- Wash your feet daily using warm (not hot) water and mild soap. Dry carefully, especially between the toes.
- Inspect your feet and toes every day for signs of redness, blisters, sores, calluses, or any changes in skin color or temperature—even if you do not feel pain.
- Use a mirror to check the bottoms of your feet, or ask for help if needed.
- Always wear closed-toe shoes or slippers to protect your feet.
- Avoid walking barefoot and avoid shoes/socks that can cause friction or moisture buildup. Well-fitting socks are highly recommended.
- Use creams or ointments to relieve dry heels—but avoid lotion between the toes.
Professional Care and Medical Monitoring
Regular monitoring of blood sugar levels is vital for all people with diabetes. Your doctor may recommend medications for neuropathy or blood sugar control. Annual podiatric exams, and more frequent visits if changes occur, are also advised. Diabetics should contact their podiatrist immediately if they notice any of the following foot symptoms:
- Changes in skin color
- Corns or calluses
- Open sores that heal slowly
- Unusual and persistent odor
- Changes in skin temperature
Complications and When to Seek Help
Diabetic wounds should always be taken seriously. Even minor wounds can become infected, and serious infections may result in sepsis or amputation if not treated early. Gangrene and ulcers are significant risks that can be prevented with vigilant daily inspection and early intervention. Do not hesitate to call your podiatrist if you suspect an issue or if home care does not lead to improvement.
Summary
Daily foot care, proper shoe choices, self-examination, and prompt professional attention are the best lines of defense for diabetic patients to prevent and manage complications. Following your healthcare professional’s advice and attending regular medical checkups are keys to maintaining foot health and overall well-being.
