A small blister, a split in the skin or a nail you cannot safely reach may seem minor. With diabetes, however, changes in feeling and circulation can mean a problem develops quietly before it becomes painful. A diabetic foot risk assessment gives you a clear picture of what is happening with your feet, what level of risk you have and what practical care will help protect them.
The purpose is not to alarm you. It is to spot preventable problems early, explain the findings in plain language and make sure your foot care is appropriate for you. For many people, an assessment brings welcome reassurance. For others, it creates a sensible plan for monitoring, professional treatment and knowing when to act quickly.
Why diabetes can affect your feet
Over time, raised blood glucose can affect the nerves and blood vessels that supply the feet. Not everyone with diabetes develops these complications, and good diabetes management can reduce the likelihood. But regular checks remain worthwhile because the early changes are not always obvious.
Nerve damage, often called peripheral neuropathy, can reduce sensation. You may not feel rubbing from a shoe, a sharp edge on a nail or a small stone in your sock. It can also cause burning, tingling, numbness or altered sensitivity, particularly at night.
Reduced circulation can slow healing and make the skin more vulnerable. Diabetes can also make infections harder to manage. When reduced feeling, pressure from footwear, hard skin and poor circulation occur together, the chance of a foot ulcer increases. An ulcer is a break in the skin that needs prompt clinical attention, even if it does not hurt.
Your risk is individual. It is shaped not only by diabetes itself, but by previous ulcers or amputation, changes in foot shape, kidney disease, smoking, sight problems, mobility, how well you can inspect your feet and the footwear you rely on each day.
What happens during a diabetic foot risk assessment?
A podiatry assessment is calm, straightforward and tailored to your needs. We begin by listening. You may be asked about your type of diabetes, how long you have had it, recent changes to your health, previous foot wounds, pain, numbness, medication and the footwear you wear for work, exercise and everyday walking.
Looking closely at skin, nails and pressure areas
Your podiatrist will examine both feet, including the soles, heels and spaces between the toes. They will look for dry or cracked skin, corns, callus, blisters, fungal infection, ingrown nails, redness, swelling and any breaks in the skin.
Hard skin is not always harmless. In a person with reduced sensation, callus can hide pressure and tissue damage underneath. The assessment also considers whether toes are clawed, prominent or crowded, whether there are bunions or other shape changes, and whether a particular area is taking too much load when you walk.
Checking sensation and nerve function
Sensation is usually assessed with a soft monofilament, a fine device that touches selected points on the foot. You will be asked whether you can feel it. This is not a painful test, and it helps identify areas where protective sensation may be reduced.
Other tests may be used as appropriate, such as checking vibration sensation or reflexes. Feeling tingling does not automatically mean you are at high risk, and having no symptoms does not rule out nerve changes. The test results, rather than symptoms alone, guide the assessment.
Assessing circulation
Your podiatrist will check the colour and temperature of your skin, look for swelling or signs of reduced blood flow, and feel for pulses at the feet where appropriate. A vascular assessment may also include Doppler testing, which uses sound waves to help assess blood flow.
Cold feet alone do not confirm poor circulation, especially in a chilly Scottish winter. Equally, warm feet do not guarantee circulation is normal. Looking at the whole clinical picture is more useful than relying on one sign.
Considering footwear, walking and self-care
The shoes you actually wear matter as much as the pair you buy for special occasions. Tight toe boxes, seams over prominent toes, loose slippers and worn soles can all create friction or instability. Bringing your usual footwear to an appointment can make the discussion more practical.
If pain, foot shape or the way you walk is increasing pressure in one area, a biomechanical assessment may be useful. Advice may include footwear changes, padding, pressure relief or orthoses where clinically appropriate. Orthoses are not necessary for everyone, but they can be valuable when they improve comfort and redistribute harmful pressure.
Understanding your foot risk level
Following the assessment, you should be told your risk category and what it means for you. In UK diabetes foot-care pathways, this is commonly described as low, moderate or high risk. A separate category, an active diabetic foot problem, is used when there is an ulcer, suspected infection, unexplained hot swollen foot, gangrene or another urgent concern.
Low risk generally means pulses and sensation are present, with no major foot deformity or history of ulceration. Regular self-checks and routine diabetes reviews still matter.
Moderate risk can include reduced sensation, reduced circulation or changes in foot shape. High risk may involve a previous ulcer or amputation, kidney replacement therapy, or a combination of reduced sensation, poor circulation and deformity. The more risk factors present, the more closely your feet should be monitored.
The category is not a judgement on how well you have looked after yourself. It is a clinical tool that helps determine how often you need review and what preventive care is sensible. Risk can change over time, so a previous low-risk result should not lead to complacency if new symptoms appear.
Everyday foot care that makes a difference
A daily check is one of the most effective habits you can build. Look at the tops, soles, heels and between the toes in good light. A mirror can help, or a family member may be able to assist if bending or sight is difficult. Look for redness, swelling, cracks, cuts, blisters, colour change or fluid on socks.
Wash and dry your feet carefully, especially between the toes. Use moisturiser for dry skin, but avoid applying it between the toes where excess moisture can encourage skin problems. Choose clean, well-fitting socks without tight elastic, and inspect the inside of shoes before putting them on.
Avoid walking barefoot, even indoors or on holiday. Do not use corn plasters, acid-based corn treatments or sharp tools to remove hard skin yourself. These can damage healthy skin, particularly when sensation is reduced. Nail cutting can also become unsafe if nails are thick, curved, difficult to reach or if you cannot clearly see what you are doing. Professional routine foot care can remove these risks while keeping you comfortable.
When to seek urgent help
Contact your GP, diabetes foot team, NHS 111 or urgent care service without delay if you notice a new wound, ulcer, spreading redness, heat, swelling, discharge, a change in colour, or a foot that becomes suddenly hot and swollen. A hot, red, swollen foot needs urgent assessment even when there is little pain, as this can sometimes indicate Charcot foot, a serious condition affecting the bones and joints.
Do not wait for a routine appointment if an infection is suspected or a wound is not healing. Early treatment can make a significant difference. If you feel generally unwell alongside a foot problem, seek urgent medical advice straight away.
A plan built around your feet and your life
A useful assessment should leave you knowing more than a risk label. You should understand what was found, which changes to watch for, how frequently you should be reviewed and what support is available for nails, corns, callus, footwear or pressure-related pain.
At 1st Foot Podiatry, diabetic foot care is approached with the same care and respect as every other foot concern: listening first, explaining clearly and tailoring treatment around your mobility, health and daily routine. If you have diabetes and have not had your feet checked recently, arranging an assessment is a practical step towards protecting the comfort and confidence that keep you moving.
