Diabetic Foot

A diabetic foot problem may involve reduced sensation, infection, pressure injury and poor arterial blood flow. A coordinated evaluation helps identify what is preventing healing and whether circulation needs to be restored.

Common findings may include foot ulcer or blister, redness, discharge or odour, blackening or colour change, reduced sensation or foot pain. Symptoms vary, and some people have advanced disease without a typical presentation.

A diabetic foot problem usually results from a combination of neuropathy, pressure, deformity, infection and reduced arterial blood flow. Loss of sensation can hide a blister or injury, while high glucose and poor circulation slow healing. Even a small wound can deteriorate when pressure continues during walking.

Long-standing or poorly controlled diabetes, previous ulcer or amputation, neuropathy, kidney disease, smoking, foot deformity, unsuitable footwear and peripheral artery disease increase risk. A person may have serious tissue damage with little pain when sensation is reduced.

Evaluation may include wound and infection assessment, arterial circulation testing, foot pressure and sensation review, blood tests and imaging when indicated. The exact test is selected after reviewing symptoms, medical history and the vascular examination.

An untreated diabetic foot ulcer can deepen, become infected, involve bone or develop gangrene. Delay may narrow the opportunity for infection control and blood-flow restoration. Redness spreading up the foot, fever, discharge, severe pain or blackening requires urgent hospital assessment.

Inspect both feet daily, including the soles and between the toes. Use protective footwear, avoid walking barefoot, control glucose, keep dressings and off-loading devices as prescribed, and never cut callus or apply strong chemicals at home. Report a new blister, colour change or wound early.

Depending on the diagnosis, options may include wound care and pressure off-loading, infection control, angioplasty or bypass when blood flow is poor, diabetes and risk-factor management. A matching symptom does not automatically make a person suitable for a particular procedure.

Rapidly spreading infection, fever, severe pain or blackening of the foot requires urgent hospital care.

Diabetic foot treatment in Hyderabad should include both wound and circulation assessment. Bring glucose records, kidney reports, current antibiotics, wound photographs and earlier Doppler or angiography so infection, pressure and arterial disease can be addressed together. Also bring a current medicine list and any relevant discharge or procedure records.
