Diabetic Foot Care in HSR Layout, Bangalore

Why are feet at risk in diabetes?

Long-standing high blood sugar damages nerves (peripheral neuropathy), so a person may not feel a stone in the shoe, a blister from new chappals, a burn from a hot floor or a cut from trimming nails. Diabetes also narrows the arteries of the legs (peripheral arterial disease), so wounds receive less oxygen and heal slowly. Changes in foot shape, dry cracked skin, thick calluses and reduced resistance to infection add to the risk.

Everyday habits matter in India. Walking barefoot at home, on terraces or in places of worship, applying home remedies or hot-water fomentation to numb feet, cutting corns with blades and wearing ill-fitting footwear are frequent starting points for ulcers. Smoking, kidney disease, poor eyesight and previous ulcers raise the risk further.

• Numbness, tingling or burning in the feet
• Weak or absent foot pulses, cold feet or calf pain on walking
• Calluses, corns, cracked heels or deformed toes
• A previous ulcer or amputation
• Smoking, kidney disease or poor vision

What does a diabetic foot ulcer look like, and when is it an emergency?

An ulcer is a break in the skin that does not heal normally, often on the sole under the ball of the foot, on the toes or at the heel. It may start under a callus and cause no pain because of nerve damage. Infection can spread quickly and silently in diabetes, sometimes deep into tendons and bone.

Seek same-day care if a foot wound becomes red, hot, swollen or smelly, discharges pus, turns black, or if you develop fever, shivering or very high or unpredictable sugars. A suddenly cold, pale and painful foot may mean a blocked artery and is an emergency. A hot, swollen foot without a wound can be acute Charcot foot, a condition that weakens the bones and needs urgent offloading.

• Spreading redness, swelling or warmth
• Pus, foul smell or a wound that is deepening
• Black or blue skin, suggesting gangrene
• Fever, chills or sugar levels out of control
• Sudden cold, pale, painful foot
• Hot, swollen foot without injury

How is a diabetic foot assessed? Tests for nerves, blood flow and infection

A thorough assessment looks at nerves, circulation, skin, foot shape, footwear and the wound itself. Sensation is tested with a monofilament and a tuning fork. Pulses are felt and the ankle-brachial index (ABI) compares blood pressure at the ankle and arm; in diabetes the arteries can be stiff and give falsely normal readings, so toe pressures or Doppler waveforms may be added. If circulation is reduced, a duplex ultrasound or CT angiography maps the blockages.

For a wound, the clinician measures its size and depth and checks whether a sterile probe reaches bone, which suggests osteomyelitis. X-rays and sometimes MRI look for bone infection or Charcot changes. Samples for culture are more reliable when taken from deep tissue after cleaning rather than surface swabs. Blood tests include HbA1c, kidney function and markers of infection. These findings are combined into a risk grade that guides treatment and follow-up.

• Monofilament and vibration testing
• Pulses, ABI, toe pressures or Doppler
• Duplex ultrasound or angiography if circulation is poor
• X-ray or MRI for bone infection
• Deep tissue culture
• HbA1c, kidney function and infection markers

Why is offloading the most important treatment for a foot ulcer?

Most plantar ulcers form because of repeated pressure on an area the person cannot feel. If pressure continues, no dressing alone can heal the wound. Offloading removes that pressure. International Working Group on the Diabetic Foot (IWGDF) guidelines recommend a non-removable knee-high device, such as a total contact cast or a removable walker made non-removable, as first choice for suitable plantar ulcers, with removable devices or special footwear where those are not appropriate.

Offloading only works if it is used for every step, including the short walk to the bathroom at night. Crutches, a wheelchair for longer distances and planning around stairs help. Once the ulcer heals, custom footwear and insoles reduce the chance of it returning.

• Total contact cast or knee-high walker for plantar ulcers
• Use the device for every step
• Limit walking and standing while the ulcer heals
• Custom footwear and insoles after healing

How are infected diabetic foot wounds treated? Debridement and antibiotics

Debridement means removing dead tissue, callus and debris so the wound can heal and its true depth is visible. It is often done in clinic with a scalpel and repeated at visits. Deep abscesses, spreading infection or wet gangrene need surgical debridement and drainage in theatre, sometimes urgently.

Antibiotics are chosen according to the severity of infection and culture results. Mild infections may be treated with tablets; moderate and severe infections often need hospital admission and intravenous antibiotics. Bone infection usually requires a longer course, often around six weeks, or removal of the infected bone. Antibiotics do not treat a wound that is not infected, and using them without need encourages resistance. Glucose control is tightened during infection, sometimes with insulin.

Dressings are chosen to keep the wound moist but not soggy, protect surrounding skin and suit the amount of discharge; no single dressing heals ulcers faster in every case. Once infection is controlled, larger wounds may be closed with stitches, skin grafts or local flaps. Negative pressure wound therapy can help some wounds after surgical debridement. Other advanced therapies are sometimes considered when good standard care has not worked, and the evidence for each varies, so ask what benefit is expected before agreeing to one.

• Regular sharp debridement of callus and dead tissue
• Surgical drainage for abscess or deep infection
• Antibiotics guided by severity and culture
• Longer treatment or bone removal for osteomyelitis
• Close sugar control during infection

Can blocked leg arteries be treated? Vascular assessment and revascularisation

If blood flow to the foot is poor, a wound may not heal however well it is dressed and offloaded. The vascular surgeon assesses whether circulation can be improved. Options include angioplasty, in which a balloon, sometimes with a stent, opens narrowed arteries from inside, and bypass surgery, which uses a vein or graft to route blood around a blockage. The choice depends on the pattern of disease, the patient’s health and kidney function.

Improving circulation is often the step that allows a wound to heal or a minor amputation site to close. Smoking cessation, blood pressure and cholesterol treatment, and medicines that reduce clotting are also part of long-term care for the arteries.

• Duplex or angiography to map blockages
• Angioplasty, with or without a stent
• Bypass surgery for selected patients
• Lifelong risk-factor treatment

Can amputation be avoided?

Many amputations can be prevented by early recognition, prompt offloading, timely treatment of infection and restoring blood flow, delivered by a coordinated team. Sometimes removing a single toe or part of the foot (a minor amputation) removes dead or infected tissue and saves the rest of the limb. A major amputation below or above the knee is considered when infection threatens life, pain cannot be controlled, or the foot cannot be saved.

These decisions are difficult, and patients and families should be told honestly about the options, risks and likely function with each. Rehabilitation, prosthetic fitting and protection of the other foot are planned whenever amputation is needed.

• Early review of any new foot wound
• Team care across medicine, surgery and wound care
• Minor amputation can sometimes save the limb
• Protect the other foot after any amputation

How long does a diabetic foot ulcer take to heal? Week by week

Healing time varies with depth, infection, circulation and how consistently the ulcer is offloaded. A shallow ulcer with good blood flow may heal in a few weeks; deep or infected wounds can take months. A typical pathway is shown below. Missing dressing visits, walking without the offloading device and uncontrolled sugar are the most common reasons for slow progress, so it helps to plan transport and a family member’s support for regular visits from the start.

• Week 0–1: assessment, debridement, offloading device, infection treatment, sugar review
• Weeks 1–4: regular dressings and debridement; wound measured to check it is shrinking
• Weeks 4–6: if the wound has not reduced meaningfully, the plan is reviewed, including circulation and bone infection
• Weeks 6–12: many uncomplicated ulcers close; skin is fragile, so offloading continues
• After healing: custom footwear, foot checks and podiatry reviews, because ulcers often recur

How much does diabetic foot treatment cost in Bangalore? Insurance and cashless

Costs vary greatly between a small ulcer treated in clinic and an infected foot needing surgery, so Lotus provides an itemised estimate for the recommended plan. The main drivers are listed below.

Hospital admission for foot infection, debridement, amputation or revascularisation is usually covered by Indian health policies, but diabetes is often a declared pre-existing condition with its own waiting period, so check your policy. Outpatient dressings and footwear are frequently not covered unless your policy includes outpatient benefits. For planned procedures, the hospital’s insurance desk seeks pre-authorisation from your insurer or third-party administrator (TPA); for emergency admissions, it notifies them promptly. Ask what the package includes, such as dressings, antibiotics and offloading devices.

• Outpatient wound care versus hospital admission
• Number of debridements and dressing materials
• Offloading devices and custom footwear
• Imaging such as MRI, duplex or angiography
• Angioplasty, stents or bypass
• Duration of intravenous antibiotics
• Kidney, heart or other conditions needing extra care

Daily foot care at home and questions to ask

Most diabetic foot problems begin with small, preventable injuries, so daily care matters as much as hospital treatment. Ask your team about your foot risk level, how often your feet should be examined, whether your circulation needs testing, what footwear is suitable, and whom to contact the same day if a wound appears.

• Check both feet every day, using a mirror or a family member’s help
• Wash in lukewarm water, testing the temperature with your elbow, and dry between the toes
• Moisturise dry skin but not between the toes
• Cut nails straight across and do not cut corns or calluses yourself
• Never walk barefoot, including indoors, and take extra care where footwear is removed
• Check inside shoes before wearing them; avoid tight or rough-seamed footwear
• Keep blood sugar, blood pressure and cholesterol in target and stop smoking
