Daily inspection, protective footwear and early clinical attention can help people with diabetes
prevent small injuries from becoming serious complications.
A small blister can become a serious health problem when diabetes has damaged the nerves or
narrowed the blood vessels that supply the feet. That is why clinicians urge people living with
diabetes to make foot checks part of their everyday routine and to seek help early when something
changes. At the Diabetes Center, protecting a patient’s foot begins with education and regular
assessment, with prompt clinical care when a concern appears.
The risk is easy to underestimate because diabetic foot problems may develop without the warning
signs people expect. Nerve damage, called peripheral neuropathy, can reduce the ability to feel pain,
heat, cold or pressure. A pebble in a shoe, a blister from a new pair of sandals or a small cut may go
unnoticed. The skin can break down while a person continues walking on the injured area.
Circulation can also be affected. Diabetes may damage blood vessels and reduce blood flow to the
legs and feet. With less blood reaching an injury, the body may have greater difficulty healing it.
When reduced sensation and poor circulation occur together, a minor wound can become an ulcer
and can become infected. In severe cases, infection or tissue damage may lead to surgery, including
amputation. Early care can interrupt that progression and may preserve mobility and independence.
These complications are not inevitable. CDC guidance says most people with diabetes can prevent
serious foot problems through regular care at home and routine health appointments. Good diabetes
management, including keeping blood glucose within an agreed target, taking prescribed medicines
and not smoking, can support overall foot health. Patients should discuss their individual risks and
care plan with their clinician, because needs differ from person to person.
A daily check is one of the simplest protective habits. Look at the tops, soles, heels and sides of both
feet, as well as between the toes and around the nails. Check for cuts, blisters, redness, swelling,
drainage, cracks, unusual warmth, new discoloration, corns or changes in nail shape. A mirror can
help with the soles; a family member or caregiver can help if bending or seeing is difficult. The
point is to notice a change before it becomes harder to treat.
Wash feet each day in warm, not hot, water and dry them carefully, especially between the toes. People with reduced sensation may not notice water that is hot enough to burn, so test it with a hand
or elbow. Moisturizer can help dry skin, but it should not be put between the toes, where excess
moisture may encourage infection. Avoid soaking in the feet, which can dry or damage the skin.
Shoes and socks are part of prevention, too. Wear properly fitting shoes and clean socks, even
indoors; walking barefoot increases the chance of stepping on something or scraping the skin.
Before putting shoes on, check inside for stones, rough seams or other objects. Break in new shoes
gradually and stop wearing them if they rub. Patients with deformities, previous ulcers or other highrisk features may need specialized footwear, which a care team can assess.
Toenails should generally be trimmed straight across and filed smooth. People who cannot see or
safely reach their feet should ask a trained health professional for help. Do not cut corners or
calluses yourself, use razor blades, or apply over-the-counter chemical removers; these can injure
skin. A clinician can recommend safe treatment. Small acts of caution matter because a wound may
not hurt when sensation is reduced.
Patients should contact their health care team promptly about a blister, open sore, cut that is not
healing, ingrown nail, swelling, redness, drainage, or a change in color or temperature. New
numbness, burning, tingling, pain, a change in foot shape, or calf pain during activity also deserves
assessment. A wound with spreading redness, pus, fever or rapidly worsening symptoms needs
urgent medical attention. Patients should not wait for a scheduled visit or try to treat a concerning
wound on their own.
The Diabetes Centers’ role is to help people recognize risk and act early. At routine appointments,
clinicians can ask about symptoms and self-care, examine the feet and identify changes that might
otherwise be missed. A comprehensive foot assessment may include checking skin, nails, foot shape,
protective sensation and circulation. The frequency and depth of follow-up depend on a patient’s
risk history, including past ulcers, neuropathy and circulation problems.
Education is another core part of prevention. Patients and caregivers can learn what to look for, how
to choose and inspect footwear, when to call the clinic and how blood glucose management fits into
foot health. A clear plan helps patients act without panic: know who to call, report a new wound
quickly and keep follow-up appointments. For people who have trouble inspecting their own feet,
involving a trusted family member can turn advice into a practical daily habit.
When a problem is found, timely assessment can guide the next step. Depending on the concern,
care may involve wound treatment, pressure relief, infection evaluation, footwear changes or referral
to a foot, vascular or surgical specialist. The International Working Group on Diabetic Foot
recommends organized, multidisciplinary care for prevention and management. That approach
brings relevant expertise together so the wound, circulation, infection risk and the person’s
broader diabetes care can be considered in one plan.
Clinical foot checks can detect changes patients may not feel. CDC recommends that people with
diabetes ask for basic foot checks at health care visits and have a comprehensive exam at least once
a year, with more frequent assessment for some people. During an exam, a clinician may test
protective sensation and circulation, inspect the skin and nails, and look for pressure points or
structural changes. A history of an ulcer or amputation raises concern and should be shared with
every member of the care team. The check is a chance to update prevention advice and agree on
when to return. Do not assume that feet are healthy simply because they do not hurt; reduced feeling
can hide a problem.
The protective routine should fit daily life. Some people examine their feet before bed; others pair
the check with getting dressed or removing shoes after work. Consistency matters more than the
hour. People who have lost sensation should avoid heating pads and hot water bottles on their feet
because burns may go unnoticed. They should also protect feet from very cold conditions and avoid
tight socks that leave marks. Gentle movement and putting feet up when sitting may support
circulation, but patients with pain, ulcers or significant circulation problems should ask their
clinician which activities are appropriate.
Patients also have an important role. They can bring concerns to appointments, remove shoes and
socks when asked, mention previous wounds or amputations, and tell clinicians if shoes cause
rubbing or if daily checks are difficult. If cost, mobility, vision or access to care makes foot care
harder, saying so gives the team a chance to discuss practical support. No concern is too small to
report when it involves a foot at risk.
Foot care is not a cosmetic extra; it is part of diabetes care that protects movement, comfort and
independence. One daily inspection, protective footwear and quick contact with a clinician when
something changes can make a meaningful difference. The Diabetes Centers prevention effort
depends on partnership: patients watch their feet at home, and the care team helps assess risk,
provide guidance and respond early. Together, these steps give a small problem the best chance of
staying small.
