Diabetic Foot Care Specialist in Hyderabad

Not every diabetic foot wound carries the same risk, and grading helps decide the urgency of treatment. The Wagner classification, used widely by vascular surgeons, runs from Grade 0 (an at-risk foot with no open wound) to Grade 5 (extensive gangrene of the whole foot). Grade 1 is a superficial ulcer, Grade 2 extends to tendon or joint, Grade 3 involves deep abscess or bone infection, and Grade 4 has localised gangrene of a toe or forefoot.

Dr. Sharma explains grading to every patient in plain language because it changes decisions immediately. A Grade 1 wound may heal with dressings and offloading alone, while a Grade 3 or 4 wound almost always needs urgent imaging of the arteries, surgical debridement and sometimes revascularisation before the wound will even begin to close.

Grading is repeated at every visit, not just once, because a wound can worsen quickly if blood supply is poor or infection is missed. This staged approach avoids two extremes — under-treating a dangerous wound, or rushing to amputation when the tissue could still be saved with proper blood flow and wound care.

A diabetic foot infection can spread from skin to bone within days because high blood sugar weakens the immune response and reduces the body's ability to fight bacteria locally. Redness spreading up the leg, fever, or a foul smell are signs the infection has moved beyond the wound itself and needs urgent hospital-based treatment, not outpatient dressing changes.

Treatment usually combines surgical drainage of any pus or abscess with intravenous antibiotics chosen based on deep tissue culture, not a guess. Superficial swabs are avoided because they often grow skin bacteria that are not actually causing the deep infection, leading to the wrong antibiotic being prescribed for weeks.

When bone is infected (osteomyelitis), a longer course of antibiotics is needed, and sometimes the infected piece of bone must be surgically removed. Controlling infection early, before it undermines the whole foot, is one of the most time-critical steps in preventing amputation.

A wound in a foot with poor blood supply will not heal no matter how good the dressings are — this is the single most under-appreciated fact in diabetic foot care. Many patients spend months on dressings at home before someone checks whether the artery itself is blocked, losing precious time.

Angioplasty (balloon widening of the narrowed artery, often with a stent) is now possible even in the smallest arteries below the knee and in the foot itself, performed as a day-care, pinhole procedure under local anaesthesia. In more extensive blockages, a bypass using the patient's own vein may be required to reroute blood around the blockage.

Once blood flow is restored, the same wound that looked static for months often begins visibly healing within two to three weeks. This is why every non-healing diabetic wound deserves a vascular assessment early, rather than as a last resort.

Most diabetic foot ulcers occur on weight-bearing points of the sole, and continued walking on the wound mechanically prevents it from closing, however good the medical treatment. Offloading means redistributing pressure away from the ulcer during daily activity.

Options range from a total contact cast (a close-fitting cast that transfers pressure away from the wound) to removable cast walkers, felt padding, and custom moulded diabetic footwear once healed. The right choice depends on wound location, patient mobility and home circumstances.

Patients are often surprised that a wound they have nursed for months heals within weeks once pressure is properly offloaded alongside good blood supply — offloading is not optional add-on advice, it is core treatment.

Surgical debridement — removing dead, infected or non-viable tissue — is usually done first, because no dressing can heal a wound bed full of dead tissue. This is performed under anaesthesia in theatre for deeper wounds, or at the bedside for smaller ones.

Once the wound bed is clean, dressing choice is tailored to the wound: negative pressure wound therapy (VAC) draws out excess fluid and promotes new tissue growth in larger cavities; antimicrobial dressings control bacterial load; and growth-factor or skin-substitute dressings are used selectively for slow-healing wounds with good blood supply.

Dressings are reviewed and changed on a planned schedule, and the wound is re-measured and re-graded at each visit so that a stalled wound is identified quickly and re-investigated rather than dressed indefinitely.

The goal of every diabetic foot programme is limb salvage — saving as much of the foot as possible while keeping it functional and infection-free. Amputation is considered only when tissue is truly dead beyond recovery, when infection is life-threatening despite treatment, or when the limb cannot be made to bear weight even after all salvage options are exhausted.

When some tissue loss is unavoidable, the principle is the smallest possible amputation — for example, a single toe rather than the forefoot, or the forefoot rather than below-knee — chosen specifically to preserve a foot that can still bear weight and fit into footwear with orthotic support.

This decision is never made in isolation. It follows a full vascular work-up, an honest assessment of how much blood supply can realistically be restored, and a discussion with the patient and family about function, rehabilitation and quality of life, not just wound closure.

Diabetic foot disease sits at the intersection of vascular surgery, infection management, diabetology, podiatry and rehabilitation — no single specialty can manage it alone. A patient who sees a vascular surgeon but never gets sugar control optimised, or gets dressings without ever having the artery checked, is set up to fail.

At Renova Century Hospital, Dr. Sharma's programme brings vascular imaging, cath-lab access, surgical debridement, diabetology input and structured wound-care nursing together for the same patient, avoiding the delays and repeated referrals that cost precious healing time in a fragile foot.

This integrated approach is particularly valuable for patients travelling from outside Hyderabad, who cannot afford multiple separate hospital visits across specialities and need decisions made efficiently in one place.

The highest risk of a new ulcer or amputation on the same or opposite foot is in the first two years after a wound has healed — recurrence, not the first wound, is often what ultimately costs a patient their limb. Structured follow-up is therefore not optional after discharge.

This includes periodic vascular review, foot examination for pressure points or callus build-up, footwear checks, and reinforcement of daily self-care habits. Patients who continue diabetologist care for tight sugar control alongside podiatry review have meaningfully lower rates of new ulceration.

Every healed patient is counselled that a healed foot is not a cured foot — it remains a high-risk foot for life, and the daily habits that prevented the first wound remain the best protection against a second one.
