Living with diabetes means paying attention to more than your blood sugar. Your foot health deserves the same level of care. Over time, diabetes can damage the nerves and blood vessels that help keep your feet healthy. When that happens, a small blister, cut, or pressure point can develop into a serious wound that threatens your mobility and, in severe cases, may lead to amputation.
As a foot and ankle surgeon, I believe that protecting your ability to move starts with prevention, early detection, and the right medical care. Many serious diabetic foot complications can be prevented or addressed more effectively when problems are recognized early.
My goal is to help patients understand their risks, recognize warning signs, and take practical steps to protect their long-term quality of life.
Diabetes can affect your feet in two particularly important ways: nerve damage and reduced blood flow.
Diabetic neuropathy occurs when high blood sugar damages nerves, often affecting sensation in the feet and lower legs. You may experience tingling, burning, or numbness. In some cases, you may lose enough sensation that you no longer notice an injury when it happens.
Imagine walking around with a small stone inside your shoe. If you have normal sensation, discomfort will usually prompt you to remove it. If nerve damage has reduced your ability to feel pressure or pain, you may continue walking until the friction creates a blister or open wound.
Diabetes can also contribute to peripheral artery disease, which reduces blood flow to the legs and feet. When circulation is compromised, the body may have greater difficulty healing wounds and fighting infection.
These problems can become especially dangerous when they occur together. An unnoticed injury can develop into an ulcer, the wound may become infected, and poor circulation can make healing more difficult. In severe cases, tissue damage or an uncontrolled infection can lead to amputation.
The good news is that daily foot care, routine medical examinations, and prompt treatment can help reduce these risks. (CDC)
Preventing diabetic foot complications does not require a complicated routine. It does require consistency.
One of the simplest and most important habits is checking your feet daily, even when they feel completely normal.
Look for:
Pay attention to the soles of your feet, your heels, and the spaces between your toes. Use a mirror if you cannot see the bottoms of your feet easily, or ask someone you trust to help.
I encourage patients to make this a regular part of their daily routine, such as checking their feet when they get ready for bed. A few minutes of prevention can help identify a problem before it becomes more serious.
Footwear plays a significant role in preventing injuries. Shoes that rub, pinch, or place excessive pressure on certain areas can create blisters and ulcers, particularly when sensation is reduced.
Choose shoes that fit comfortably, provide adequate support, and leave enough room for your toes. Wear clean socks, and check the inside of your shoes for small objects, rough seams, or anything that could irritate your skin.
I also advise patients with diabetes to avoid walking barefoot, even indoors. Stepping on a sharp object or stubbing a toe can cause an injury you may not immediately feel.
If you have foot deformities, a history of ulcers, or areas of persistent pressure, ask your healthcare provider whether therapeutic footwear, custom inserts, or other protective measures would be appropriate.
Healthy skin provides an important barrier against infection. Wash your feet daily with warm, not hot, water and dry them carefully, especially between your toes.
If your skin is dry, apply moisturizer to help prevent cracking. Avoid applying lotion between your toes, where excess moisture can encourage skin problems.
Trim your toenails straight across and smooth any sharp edges. If your nails are thick, difficult to reach, or difficult to see, ask a qualified foot care professional for assistance.
Be particularly cautious with corns and calluses. Do not cut them yourself or use over-the-counter chemical removal products without medical guidance. These treatments can injure the skin and create an opening for infection.
Foot care is only one part of preventing complications. Managing diabetes and other conditions that affect circulation is equally important.
Work with your healthcare team to manage your blood glucose, blood pressure, and cholesterol. Take prescribed medications as directed, follow an appropriate nutrition plan, and discuss safe physical activity with your clinician.
If you smoke, ask about support for quitting. Smoking can further impair circulation and make it harder for wounds to heal.
Movement remains important, but the right type and amount of activity depend on your individual foot health. If you have an active ulcer, significant numbness, or a suspected injury, seek medical advice before continuing activities that place pressure on the affected foot.
Protecting your mobility means finding ways to stay active without exposing your feet to unnecessary risk.
Daily self-checks are valuable, but they do not replace a professional examination.
I encourage patients with diabetes to discuss foot health at routine medical appointments and receive a comprehensive foot examination at least annually. Depending on your circulation, sensation, foot structure, and medical history, you may need more frequent evaluations.
A clinician can assess sensation, circulation, skin condition, deformities, and other risk factors that may not be obvious at home.
If you have previously had a foot ulcer or amputation, or if you have significant neuropathy or circulation problems, ongoing specialist care is particularly important.
The goal is to identify risks before they lead to a wound, infection, or loss of function.
One of the biggest mistakes a person with diabetes can make is assuming that a foot problem is harmless because it does not hurt.
Nerve damage can reduce pain sensation, so the absence of pain does not necessarily mean the absence of injury.
Contact a healthcare professional promptly if you notice a blister, cut, sore, or ulcer that is not healing, or if you develop new swelling, redness, warmth, discoloration, or drainage.
Seek urgent medical attention for signs of a potentially serious infection, including rapidly worsening redness or swelling, spreading discoloration, pus, fever, or blackened tissue. Do not wait for your next scheduled appointment if you suspect an infection is progressing.
If you discover a wound, avoid putting unnecessary pressure on it and arrange prompt medical assessment. Do not attempt to remove damaged tissue or treat a deep wound yourself.
Early evaluation can help determine what treatment is needed and whether additional testing or specialist care is appropriate. (NIDDK)
A diabetic foot ulcer is an open wound that can develop when repeated pressure, friction, injury, or other damage breaks down the skin.
Some ulcers begin as small blisters or calluses. Others develop beneath areas of pressure that are difficult to see. When reduced sensation prevents you from recognizing the injury, everyday activities can continue to aggravate it.
Treatment depends on the wound's depth, location, circulation, and whether infection is present. Care may include relieving pressure on the affected area, specialized wound care, treatment for infection when indicated, and evaluation of blood flow.
In some cases, additional procedures are needed to improve circulation or remove infected or nonviable tissue. Severe infections may require surgery, including amputation when necessary to control the infection and protect the patient's overall health.
However, an ulcer does not automatically mean amputation is inevitable.
My priority is to help patients receive appropriate care as early as possible, address the factors preventing healing, and preserve a functional foot whenever medically feasible. The right treatment depends on the individual situation, which is why an examination matters.
Diabetic foot complications can involve several interconnected problems, including nerve damage, circulation changes, skin breakdown, infection, and structural deformities.
Managing these issues sometimes requires coordinated care among a primary care clinician, diabetes specialist, vascular specialist, podiatrist, wound care team, and orthopedic foot and ankle surgeon.
As one of the ankle surgeons treating complex foot and ankle conditions, I look at more than the immediate injury. I want to understand how the foot functions, whether its structure is contributing to pressure or instability, and what factors may interfere with healing.
For selected patients, advanced imaging, surgical planning, reconstructive techniques, and minimally invasive approaches may play a role in treatment. The appropriate approach depends on the patient's condition, overall health, and goals.
Surgery is not necessary for every diabetic foot problem, and it is not a substitute for preventive care. But when a structural problem, severe deformity, or another complex condition threatens function, specialist evaluation can help determine whether an intervention may improve the patient's outlook.
Ultimately, the objective is to control the underlying problem, support healing, and preserve independence whenever possible.
Your feet support nearly everything you do, from walking around your home to exercising, working, traveling, and spending time with family. Protecting them is an important part of protecting your independence.
If you have diabetes, start with the fundamentals: inspect your feet every day, wear protective footwear, manage your blood sugar, attend routine examinations, and seek medical attention when something changes.
You do not need to wait for pain or a serious wound before asking for help. In fact, early evaluation is often the best opportunity to address a developing problem before it threatens your mobility.
I believe that informed patients are better equipped to make decisions about their health. My approach to foot and ankle care centers on understanding each patient's needs, evaluating the available treatment options, and using appropriate techniques and technologies to support the best possible functional outcome.
If you are experiencing a diabetic foot complication, have a history of foot ulcers, or are concerned about a change in your foot's condition, I encourage you to seek an appropriate medical evaluation.
