Foot Care for Dialysis Patients 2026 | Podiatrist

Patients receiving dialysis for end-stage kidney disease (ESKD) have a constellation of systemic abnormalities that make the foot uniquely vulnerable — the foot is often the first organ system where the combined effects of uremia, diabetes, peripheral arterial disease, and neuropathy manifest as catastrophic complications. The disease burden that targets the foot: diabetes is the leading cause of ESKD in the United States, accounting for approximately 38% of dialysis patients; diabetic patients on dialysis have simultaneously: peripheral arterial disease (PAD): the combination of diabetes and uremia accelerates atherosclerosis; PAD is present in 30–50% of dialysis patients; the foot is at the end of the arterial tree and receives the least collateral blood flow when proximal vessels narrow; diabetic peripheral neuropathy: loss of protective sensation; uremic neuropathy (from the toxin accumulation of kidney failure): even non-diabetic ESKD patients develop peripheral neuropathy from uremic toxins; this creates a neuropathic foot in dialysis patients without diabetes; impaired immune function: uremia suppresses neutrophil chemotaxis and phagocytosis; infections in dialysis patients spread faster, respond more slowly to antibiotics, and produce tissue destruction at a rate that overwhelms the limited healing capacity; calciphylaxis (vascular calcification of small vessels): a specific complication of ESKD where calcium deposits occlude small arterioles in the skin and subcutaneous tissue; produces extremely painful, necrotic skin ulcers that are very difficult to treat; the skin overlying the foot and lower leg is a common site. The result of this disease burden: dialysis patients have a risk of lower extremity amputation that is 7–10 times higher than non-dialysis patients with diabetes; foot ulcers in dialysis patients heal significantly more slowly and have substantially higher amputation rates than ulcers in diabetics without kidney disease.

Dialysis patients require a systematic, daily foot care protocol — the impaired healing, infection risk, and sensory loss that characterize ESKD make missed findings and delayed treatment catastrophic. The daily foot inspection protocol: the single most important foot care behavior; inspect ALL surfaces of both feet every day without exception; the plantar surface must be examined — place a mirror on the floor or use a handheld mirror to see under the foot; look for: any new break in the skin (any size — even a 2mm wound is significant); blisters from shoe friction (a blister that pops becomes an open wound in this patient population); areas of redness or increased skin warmth (indicating inflammation or infection); callus buildup (a precursor to ulceration); nail changes (discoloration, subungual hematoma indicating pressure, nail bed separation); a spouse, family member, or home health aide should perform or assist with the inspection; self-inspection is unreliable in patients with visual impairment or limited mobility. Daily foot hygiene: wash feet in lukewarm water (never hot — neuropathy prevents sensing scalding temperatures); water temperature should be tested with the elbow before placing the foot in water; dry feet thoroughly, paying particular attention to between the toes — moisture retention between the toes promotes fungal infection and skin maceration; apply a fragrance-free, lanolin-based moisturizer to the entire foot (except between the toes) to prevent dryness, fissuring, and cracking; Eucerin, Aquaphor, or urea-based creams are appropriate choices; dry, cracked heel fissures in dialysis patients can become entry points for infection — consistent moisturizing prevents this. Nail care: trim nails straight across, never at the corners — this prevents ingrown toenails; use clean nail clippers; do not cut deeply into the corners; if vision, dexterity, or sensation impairment makes self-care risky, professional nail care by a podiatrist every 6–8 weeks is safer than self-care; never use scissors or knives on diabetic or dialysis patient nails.

Footwear selection is a primary preventive intervention for dialysis patients — the right shoe and sock combination dramatically reduces the pressure, friction, and shear forces that initiate skin breakdown in feet with impaired healing capacity. Shoe requirements for dialysis patients: the therapeutic shoe is not optional for dialysis patients with neuropathy — it is a medical necessity; key features: extra depth: the toe box must be deep enough to accommodate hammertoe deformity without dorsal toe contact; a 3/8-inch deeper toe box than a standard shoe accommodates typical hammertoe deformities; wide toe box: wide and extra-wide sizing accommodates forefoot edema (swelling), which is particularly common in dialysis patients due to fluid shifts; seam-free interior: internal shoe seams can create pressure points that are invisible to the neuropathic patient but produce pressure necrosis over days to weeks; seamless or minimal-seam interiors are essential; cushioned, shock-absorbing insole: reduces peak plantar pressure at the metatarsal heads; accommodative custom insoles with pressure relief cut-outs over callus and high-pressure areas are ideal; firm, structured heel counter: prevents pronation-related rubbing at the medial heel; closures: Velcro or adjustable closures accommodate the fluctuating foot swelling that dialysis patients experience day-to-day (feet are larger post-dialysis, smaller on non-dialysis days); Medicare coverage: Medicare Part B covers one pair of therapeutic diabetic shoes and three pairs of custom insoles per calendar year for diabetic patients with documented neuropathy — dialysis patients with diabetes should utilize this benefit. Sock requirements: seamless socks (no toe seams — conventional socks' toe seams can cause pressure necrosis in neuropathic patients); moisture-wicking material (wool or synthetic blends — not cotton, which retains moisture); white socks: allows detection of wound drainage (dark sock colors obscure drainage that would alert the patient to a wound); non-constrictive band: the sock's top band must not indent the lower leg (creating a tourniquet effect that worsens venous return in patients who already have vascular compromise).

Podiatric visit frequency for dialysis patients should be more aggressive than for diabetics without kidney disease — the compounded risk of PAD, neuropathy, uremic immune suppression, and impaired healing makes early detection and prevention a life-and-limb-saving priority. Recommended visit frequency by risk level: all dialysis patients should see a podiatrist at least every 2–3 months; this frequency applies even to patients without active foot problems — the visit is a proactive surveillance tool; for dialysis patients with any of the following high-risk features, monthly visits are appropriate: prior foot ulceration (the single strongest predictor of future ulceration); partial foot amputation (altered biomechanics create new pressure points at the residual foot); active PAD with documented reduced toe pressures or ankle-brachial index below 0.6; active hammertoe or bunion deformity with areas of shoe pressure; chronic kidney disease patients approaching dialysis initiation should begin establishing podiatric care before reaching ESKD. What the podiatric visit accomplishes: nail and callus management: regular professional nail trimming and callus debridement eliminates the most common ulcer precursors; a podiatrist can safely perform these services on a vascular-compromised foot; callus debridement (shaving off the hyperkeratotic skin) removes the rigid skin that concentrates plantar pressure and produces subcallus hemorrhage (the immediate ulcer precursor); Doppler assessment: noninvasive assessment of pedal blood flow at each visit provides early warning of PAD progression; shoe and insole evaluation: the podiatrist can identify where the shoe is contacting the foot abnormally before a wound develops; wound surveillance: any minor skin break, blister, or fissure is treated at the visit rather than being managed (or mismanaged) by the patient at home; coordination: the podiatrist serves as the first responder for foot complications in dialysis patients and must have clear communication pathways to vascular surgery, infectious disease, and the patient's nephrologist.
