Diabetic Foot Wound Care for Older Adults: Daily Foot Checks, What Not to Do, and When to See a Doctor

How should you care for a diabetic foot wound? Find it early and get it seen early. People with diabetes often have numb feet, so a small wound may not hurt and can be left until it spreads. Families can do three things that genuinely help: check your parent's feet every day, care for skin that has no wound yet in the right way, and have any new wound assessed by a doctor within the next working day. A wound with swelling, redness and heat, pus, toes turning dusky, or a fever needs hospital care today, not a wait-and-see approach.

A situation home-visit nurses see often: a mother has had diabetes for years and wears flip-flops around the house. One day her daughter notices a fluid stain on her sock and finds a coin-sized wound on the sole. "But it doesn't hurt at all," her mother says, even though the wound may have been there for days. This guide is for adult children caring for a parent with diabetes at home: what to check, what you can do yourself, what to avoid, and when to hand over to a doctor or nurse.

Quick answer

• Diabetes can cause numbness and reduced blood flow in the feet, especially in people who have had it for many years or have other risk factors, so wounds may not hurt, may heal slowly and can get infected easily. No pain does not mean a wound is minor.
• Check both feet every day: the tops, soles, heels, between the toes and the nails. Use a mirror or ask a family member if the soles are hard to see.
• Never soak the feet, use hot-water bottles, cut calluses or trim a wound with anything sharp, or put creams or herbal remedies on a wound without advice.
• A new wound, blister or crack, even a small painless one, should be assessed by a doctor or diabetic foot clinic within the next working day.
• A wound with fever, chills or drowsiness, or toes turning dusky or black, spreading redness and heat, pus or a bad smell, needs hospital care immediately.
• Once a doctor has set a wound-care plan, the family can follow it, or a registered nurse can dress the wound at home according to the doctor's treatment plan.

1. Why diabetic foot wounds spread faster than ordinary wounds

Diabetic foot wounds can spread quickly because up to three problems may overlap: numbness, poor blood supply and a higher risk of infection. Not everyone with diabetes has all of them, but the longer someone has had diabetes, or the less well controlled it is, the more likely they are. When they are present, a wound that would heal in days for most people can become a long-lasting one. The US Centers for Disease Control and Prevention (CDC) says about half of all people with diabetes have some kind of nerve damage, which is why the doctor needs to assess each person's foot risk individually.

• Numbness (nerve damage). Years of high blood glucose can damage the nerves in the feet, so your parent may not feel a tight shoe, a pebble inside it, or water that is too hot. Numbness, tingling, or burning pain in the feet are worth telling the doctor about.
• Poor blood supply. When the arteries to the legs are narrowed, wounds heal poorly. Doctors often check the foot pulses or order a circulation test before planning wound care.
• Infection. Germs can enter through tiny cracks. In older adults, infection may not cause much pain; sometimes the first sign the family notices is drowsiness, poor appetite or unusual swings in blood glucose.
• Repeated pressure on the same spot. The ball of the foot, the heel and deformed toes take weight with every step. Thick callus there signals high pressure and is a common place for wounds to start.

Blood glucose control, medicines and insulin are covered in our guide on diabetes and insulin care for older adults at home. This article focuses only on the feet and wounds.

2. A step-by-step daily diabetic foot check in under two minutes

A daily foot check is the most effective thing a family can do, because a wound found on day one is far easier to manage than one found a week later. Thailand's diabetes clinical practice guideline and the US Centers for Disease Control and Prevention (CDC) both recommend checking the feet every day.

How to check

1. Choose the same time each day, such as after the evening shower or before bed, in good light.
2. Have your parent sit on a chair with a backrest rather than stand on one leg.
3. Look at the tops of both feet and ankles for redness, swelling, scrapes or shoe-pressure marks.
4. Look at the soles, the ball of the foot and the heels. If your parent cannot bend or see well, use a mirror or look for them.
5. Spread the toes one gap at a time and look for white, soggy skin, cracks or fungal infection.
6. Look at the nails for ingrown, thickened nails or red, swollen skin around them.
7. Compare both feet with the back of your hand. If one foot is clearly warmer or more swollen, tell the doctor.
8. Feel inside each shoe before your parent puts it on, because they may not feel a pebble or hard object.

What to note and report

Wounds or scrapes, blisters, cracked skin, callus that is discoloured or weeping, ingrown nails, redness that does not fade after shoes come off, one hot swollen foot, toes changing colour, and any unusual smell. Take a dated photo each time, so the doctor or nurse can see how the wound changes.

A nurse's tip: make the foot check part of a routine your parent already has, such as right after putting on lotion or before evening prayers. When it follows something you do every day anyway, the family can keep it up without having to remember an extra task.

Check daily at home, and have professionals check too

The family's check does not replace a foot examination by a doctor or nurse. The UK NICE guideline (NG19) recommends assessing foot risk at least once a year for people at low risk, and more often as risk rises, for example every 3 to 6 months for moderate risk and every 1 to 2 months for high risk. People who already have a wound should be seen as often as the wound-care team arranges. Ask the doctor which risk group your parent is in, and ask for shoes and socks to come off so the feet are examined at every visit.

3. Caring for feet without wounds to prevent diabetic foot ulcers

Feet without wounds need clean, dry, uncracked skin that is protected from pressure and cuts. The points below follow Thailand's 2023 diabetes clinical practice guideline and CDC advice.

Washing and drying

• Wash the feet every day in room-temperature or slightly warm water. Test it with your elbow first; it should not be above 35°C, which feels just lukewarm, because numb feet cannot tell when water is too hot.
• Do not leave the feet soaking. Skin that soaks for long becomes soft and cracks easily.
• Dry the whole foot, especially between the toes, by gently patting with a soft towel.

Moisturising

• Apply lotion to the tops and soles to prevent dry, cracked skin.
• Do not put lotion between the toes, as trapped moisture softens the skin and can lead to infection.

Nails, calluses and corns

• Trim normal nails after a bath when they are soft. Cut straight across along the nail edge, not deep into the corners, then file sharp edges.
• If your parent cannot see or reach their feet, has numb feet, or has thick, yellowed, misshapen or ingrown nails, have a health professional or foot clinic trim them. Family members should not cut these nails with sharp tools at home: thick, hard nails are difficult to cut, a slip can easily nick the skin, and your parent may not feel the wound.
• Do not cut, file or pick at calluses or corns at home, and do not use over-the-counter corn removers. Numb skin can be injured without anyone noticing. Let a doctor or foot clinic handle them.

Shoes and socks

• Never go barefoot, indoors or outdoors. Always wear shoes or closed-heel house shoes with soft soles.
• Choose shoes wide enough for the toes to move, with no seams pressing on the toes. Try new shoes in the afternoon, when feet are slightly swollen, and wear them for short periods at first.
• Wear clean socks without raised seams or tight tops, and change them daily.
• Do not use hot-water bottles, heat pads or warm the feet near a fire, even if your parent complains of cold feet. Use socks instead.

Older adults who are bedbound also face pressure on the heels and ankles. Those are pressure sores rather than diabetic wounds, but they heal just as poorly. See how to prevent pressure sores at home for floating the heels and positioning.

4. When there is already a wound: what you can and cannot do

When a person with diabetes has a foot wound, the first step is for a doctor to assess the type of wound, its depth, any infection and the blood supply before deciding how to dress it. Families should not decide on their own that a wound is "small enough to handle", because numbness hides how deep a wound may be.

While waiting to see the doctor, you can

• Wash your hands before touching the foot.
• Cover it for now with a dry sterile gauze pad (from an unopened pack), placed without wrapping tightly, and do not keep lifting it to look while you wait for the doctor. Do not use gauze from an already-opened pack or ordinary cloth on the wound.
• Do not burst blisters, and do not apply antiseptics unless the doctor has told you to.
• Help your parent keep weight off that foot, sitting or lying with the foot rested more often.
• Photograph the wound and note when it started, any fever, and recent blood glucose readings to show the doctor.

Can your parent shower with a foot wound?

Yes, but never soak the wound, and follow the method set by the doctor or nurse caring for it. In general, keep the dressing dry while showering, for example by sitting on a shower chair with the affected foot kept out of the water, or using a waterproof cover as the nurse advises. If the dressing gets wet or comes off, change it the way the team taught you. If no one has taught you yet, cover it temporarily with dry sterile gauze and call the nurse.

Do not

• Do not soak the foot in warm water, salt water or herbal water. King Chulalongkorn Memorial Hospital advises clearly against cleaning a wound by soaking the foot.
• Do not trim the wound, cut the callus around it or pop a blister with anything sharp at home. Dead tissue must only be removed by a doctor or diabetic foot care team.
• Do not choose your own wound products. Do not put alcohol, powders, herbal remedies, balms or self-bought antibiotics on the wound. The cleaning solution and dressing depend on the wound, and a doctor or nurse should decide them.
• Do not wait for pain. A numb foot may not hurt at all, even when the wound is infected.

Once the doctor has set a plan

The doctor will decide what to clean the wound with, which dressing to use, how often to change it, and how to take pressure off the wound, for example with special footwear or devices. Offloading matters as much as the dressing: if your parent keeps walking on the wound every day, it will struggle to heal. Ask the doctor four clear questions before you go home.

1. What do we clean it with, what do we cover it with, and how many times a day?
2. How much can my parent walk, and which shoes or devices are needed?
3. Which signs mean we should come back before the next appointment?
4. When is the next appointment, and whom do we contact out of hours?

If the family is not confident dressing the wound, or nobody is home when it needs changing, a registered nurse can dress it at home according to the doctor's treatment plan. See what a home nurse visit includes.

5. Which diabetic foot wounds need urgent care: a three-level plan

Every diabetic foot wound should be under a doctor's eye, but the urgency differs. This plan draws on the UK NICE guideline NG19, which advises referring people with active diabetic foot problems that are not emergencies to a diabetic foot care team within 1 working day and sending people to hospital immediately when there are life- or limb-threatening signs, together with advice from King Chulalongkorn Memorial Hospital.

Continue care at home, watch closely

• Dry skin or thin callus with no wound, redness or swelling.
• A wound the doctor has already assessed, being dressed to plan and steadily improving, with no spreading redness and less fluid.
• Keep going: daily checks, comparison photos and attending appointments.

Call a nurse today and have a doctor assess within the next working day

• A new wound, blister, crack or scrape, even if small and painless.
• An ingrown nail with red or weeping skin around it.
• An existing wound that is not improving, staying the same size or growing, or producing more fluid.
• One foot that is swollen, red and warmer than the other, or a change in foot shape, even without a wound or pain. This can be Charcot foot, a diabetes-related joint and bone problem. Stop putting weight on that foot straight away, without waiting to be told, by sitting or using a wheelchair as safety allows, and have a doctor assess it within the next working day, because walking on it can make the bones and joints more deformed.

Found a wound on a Friday night, a holiday, or with no diabetic foot clinic nearby? If none of the signs in the next level are present, cover it with dry sterile gauze, keep your parent's weight off that foot and see a doctor at their usual health service, a nearby hospital or an out-of-hours clinic as soon as one is open; you do not need to wait for a specialist clinic. If even one sign in the next level is present, go to the emergency department or call 1669 without waiting for a working day.

Go to hospital or call 1669 immediately

• A wound with fever, chills, drowsiness, confusion or fast breathing, which can mean infection spreading into the blood.
• Toes or skin around the wound turning dusky or black.
• Swelling, redness and heat around the wound spreading quickly, pus, or a bad smell.
• A wound with a cold, pale or very painful foot, which may mean the blood supply is not enough.
• Your parent is hard to wake or has difficulty breathing: call 1669 immediately.

If your parent has a fever or seems drowsy and you are not sure it comes from the wound, read the warning signs in bedridden fever, phlegm and drowsiness.

6. Dividing the work at home

Diabetic foot care at home depends on someone checking the feet every single day, more than on one person who is good at dressings. Sharing the work this way helps make sure no day is missed.

• Your parent, if able, tells you about numbness, tingling, tight shoes or anything unusual, and wears shoes every time they stand up.
• Family members or the main carer do the daily check, washing, drying and lotion, check inside the shoes, and keep photos and notes.
• A caregiver (nursing assistant) helps with daily care, runs through the foot checklist and notes what they see. Simple, shallow wound care of the kind families are taught to do for each other at home is a specially trained care task, done by caregivers trained for that task under the supervision of our registered-nurse team, and only for wounds a doctor or nurse has already assessed and set a dressing plan for.
• A registered nurse dresses diabetic wounds that are deep, infected or complex according to the doctor's treatment plan, assesses the wound at each visit and tells the family if it gets worse.
• The doctor and diabetic foot team assess the wound, order dressings, remove dead tissue, prescribe medicines and decide on offloading devices.

Common mistakes families make

• Waiting for your parent to say it hurts. Numb feet do not send pain signals. Fix: look every day rather than relying on how your parent feels.
• Soaking the feet in warm or herbal water to "clean" them. The skin softens, wounds spread and burns can happen. Fix: wash, then dry straight away.
• Cutting calluses, picking corns or trimming thick, misshapen nails at home with scissors or blades, creating new wounds no one notices. Fix: let a doctor or foot clinic do it.
• Using wound remedies recommended by friends. Powders, herbs or alcohol can damage tissue and hide infection. Fix: use only what the doctor or nurse prescribes.
• Letting your parent wear flip-flops or go barefoot indoors. Toes are easily knocked and cut. Fix: closed-heel house shoes.
• Skipping appointments because the wound "looks better". Even when the skin on top looks closed, a deeper wound, infection or pressure on the tissue underneath may not have healed. Fix: keep going until the doctor says treatment is complete.

When to bring in professional help

Most families can look after their parent's feet once they know how. But if the doctor orders daily or alternate-day dressings, family members work full time, or everyone is worried about doing it wrong, a professional team can share the load. KIN HomeCare services that fit this situation:

• Registered nurse wound dressing at home according to the doctor's treatment plan, THB 1,200 per visit, with a wound assessment and notes each time for the family to show the doctor.
• Wound-care courses for wounds needing ongoing care: 10 visits THB 10,800 · 20 visits THB 19,200.
• Caregivers at home for daily care, foot checks, footwear and hygiene: 12-hour shift THB 1,800 per day (minimum 3 days). See elderly home care.
• Escort to wound-clinic appointments: a caregiver picks your parent up, stays throughout and brings them home, THB 1,800 for 8 hours, then 200 baht per extra hour; transport is charged separately.

Frequently asked questions

Can I clean a diabetic foot wound with saline at home?

Only once the doctor or nurse caring for the wound has told you to and shown you how. Sterile saline is a commonly used wound-cleaning solution, but how to clean, how often and which dressing to use depend on the type of wound and whether it is infected. While waiting to see the doctor, cover it with dry sterile gauze and do not add alcohol, powders or herbal remedies yourself.

Can a small diabetic foot wound be dressed at home?

Yes, but only after a doctor has assessed it and explained how. A wound that looks small may be deeper than it appears, and your parent may feel no pain. Have it assessed within the next working day, then follow that plan.

Can someone with a diabetic foot wound shower or soak their feet?

They can shower, but should never soak the foot or the wound. Soaking softens the skin, lets the wound spread, and numb feet can be scalded without noticing. Keep the dressing dry while showering as the nurse advises, and if it gets wet or comes off, change it the way the care team taught you.

Which diabetic foot wounds need hospital care right away?

A wound with fever, chills or drowsiness, toes turning dusky or black, rapidly spreading redness and heat, pus or a bad smell, or a cold, pale and very painful foot. Go to hospital that day or call 1669. These signs suggest the wound may be spreading in a way that threatens the toes or leg, so do not wait and see.

How often should a doctor check diabetic feet?

At least once a year for people at low risk, and more often as risk increases. The UK NICE guideline gives examples of every 3 to 6 months for moderate risk and every 1 to 2 months for high risk, while people with an active wound are seen as the wound-care team arranges. Ask the doctor which group your parent is in, and keep checking at home every day as well.

Can someone with a diabetic wound eat eggs?

Yes. There is no evidence that eggs make wounds fill with pus. Wounds need protein and energy to repair, and cutting out eggs, meat or milk because of folk beliefs may slow healing, unless the doctor has restricted certain foods for another reason, such as kidney disease or an allergy. For rice and sweets, follow the doctor's or dietitian's advice on blood glucose control.

Can KIN HomeCare send a nurse to dress a diabetic foot wound at home?

Yes. A registered nurse dresses the wound at home according to the doctor's treatment plan, from THB 1,200 per visit, with courses of 10 visits for THB 10,800 and 20 visits for THB 19,200. Travel costs depend on the area, and staff confirm them before booking.
