Diabetic Foot Ulcer Prevention in Kathmandu: Daily Checks, Footwear, and Blood Sugar Control

<p>Diabetic foot ulcers are among the most feared complications of diabetes because they can progress from a small blister to deep infection, prolonged healing, hospitalization, and in severe cases limb loss. Global guidance emphasizes that most ulcers are preventable when neuropathy, peripheral arterial disease, and repetitive pressure are recognised and systematically addressed. At orthopedic and diabetic foot care in Kathmandu with Dr. Bodh Raj Gautam (NMC 23071, MBBS KU, MS Orthopedics, Cert. Podiatry & Diabetic Foot), ulcer prevention is built around daily self-checks, footwear, skin and callus management, and vascular and glycaemic optimization, not around any single product.</p> <h2>The triad that creates ulcers</h2> <p>Three factors usually converge. Diabetic peripheral neuropathy dulls protective sensation and proprioception, so friction and pressure go unnoticed, and autonomic neuropathy reduces sweating, leaving skin dry and prone to fissure. Peripheral arterial disease limits oxygen and nutrient delivery needed for tissue integrity and repair, so minor trauma heals slowly. Repetitive mechanical stress over bony prominences, especially the metatarsal heads, heels, and pressure points of deformed toes, then breaks skin that cannot heal efficiently. Hyperglycaemia, smoking, duration of diabetes, foot deformity such as bunion or Charcot changes, and prior ulcer or amputation further raise risk. International Working Group on the Diabetic Foot (IWGDF) risk stratification captures this: no neuropathy equals low risk, neuropathy alone equals moderate risk, neuropathy with deformity or arterial disease equals high risk, and prior ulcer equals very high risk.</p> <h2>Daily checks that take two minutes</h2> <p>Guidelines recommend inspecting both feet daily, including the plantar surface with a mirror or with help from a family member, the interdigital spaces, and under callus. Look for blisters, cuts, red spots that do not blanch, swelling, warmth, or new callus formation signaling repetitive pressure. Technique matters:</p> <ul> <li>Wash with lukewarm water and mild soap, test temperature with the elbow if neuropathy is present, and dry thoroughly between toes.</li> <li>Moisturize dry skin on the dorsum and plantar surface but avoid leaving cream between toes where maceration promotes fungal growth.</li> <li>Trim nails straight across and file gently; do not cut callus or corns at home with blades, and do not use medicated corn plasters that contain caustics near neuropathic skin.</li> <li>Never walk barefoot, even indoors. Check inside shoes for foreign bodies or seams before each use, especially after monsoon dampness.</li> <li>Break in new shoes gradually and inspect feet after the first hours of wear for red areas.</li> </ul> <p>Record findings in a simple diary or phone photo log to show at clinic; early detection days earlier often means a dressing and offloading decision instead of debridement later.</p> <h2>Footwear, callus, and offloading</h2> <p>Offloading removes the repetitive pressure that opens skin. Preventive footwear must accommodate deformity without creating new pressure. Medical consensus supports:</p> <ul> <li>Shoes with adequate length and a wide, deep toe box, cushioned but stable sole, and lacing that prevents sliding. The counter should be firm enough to control hindfoot stability.</li> <li>Seam-free interior and socks that wick moisture; change socks when damp and avoid tight elastic that impairs circulation.</li> <li>For high-risk feet, prefabricated or custom orthoses with metatarsal offloading, and when indicated, molded insoles or rocker soles that redistribute forefoot pressure.</li> <li>Regular professional callus debridement, because thick callus beneath metatarsal heads concentrates pressure and precedes ulceration. Home blade reduction is not recommended.</li> </ul> <p>Once a pre-ulcerative lesion or blister appears, strict offloading with a removable walker, healing sandal, or when indicated a total contact cast as advised by the treating team is more effective than simply changing dressings.</p> <h2>Vascular checks, sugar control, and when to seek care urgently</h2> <p>Control of blood glucose, blood pressure, lipids, and smoking cessation improves microcirculation and wound potential, though glycaemic control alone does not instantly restore lost sensation or arterial flow. Annual comprehensive diabetic foot examination includes 10-g monofilament and vibration perception for neuropathy, palpation of dorsalis pedis and posterior tibial pulses plus ankle-brachial index when indicated, and deformity, callus, and footwear assessment. More frequent follow-up is scheduled for moderate to very high risk categories.</p> <p>Seek same-day care for a blister, crack, or callus that breaks, any wound that does not improve within 24 hours, new redness, swelling, warmth, pus or odor, a swollen warm foot suggestive of Charcot arthropathy without wound, or black or blue discoloration. Fever, pain out of proportion to wound size, or rapidly spreading redness indicates spreading infection and requires urgent evaluation. Bring your shoe and insole, medication and glucose log, and prior foot photos to help localize pressure points.</p> <h2>Surveillance schedule, team roles, and footwear renewal</h2> <p>Prevention succeeds when surveillance intensity matches risk. IWGDF guidance followed in Kathmandu schedules low-risk patients for annual comprehensive foot screening, moderate-risk patients every three to six months, high-risk every one to three months, and very high risk at one- to two-month intervals or more frequently after an ulcer heals. Each visit repeats pulse palpation and monofilament check where indicated, maps callus and pressure points, and reviews shoe interior wear. Family members involved in daily checks receive the same brief teaching as the patient, because the second pair of eyes often spots early change on the plantar surface or between toes where self-inspection is difficult.</p> <p>Footwear renewal deserves its own calendar. Insoles compress and shells deform with heat and monsoon moisture, so orthoses and offloading insoles are assessed for bottoming out, and shoes are replaced before the toe box shortens or the sole becomes slick. Patients who walk long distances for work benefit from two pairs rotated to allow drying, and from a designated indoor pair that is never barefoot contact. Coordination among diabetology for glycaemic, lipid and blood pressure control, vascular surgery when pulses are absent or wound healing stalls, and podiatric or orthotic services for callus and pressure redistribution ensures gaps do not develop between advice and access. Education at every visit revisits hypoglycaemia awareness for those on insulin or sulfonylureas, because undetected low glucose impairs self-care capacity, and smoking cessation support addresses tissue perfusion directly. This longitudinal plan remains educational, evidence-aligned, and adapted to Nepal's walking, climate, and health system realities.</p> <p>Dr. Gautam coordinates screening, footwear prescription, and wound risk counseling, and for established ulcers aligns debridement, offloading, microbiology-guided infection care, and vascular referral pathways as indicated, with education on recurrence prevention at every visit.
