foot care in diabetes.pngOne in 100 persons with diabetes faces risk of developing foot ulcer in his/her lifetime. Hence, a careful inspection of the feet should be done by a qualified podiatrist for all diabetics at every 6 months interval. Routine foot checks should include examination of the bare feet for signs of bruises, deformities or loss of sensation. If abnormalities are present, more frequent evaluation of the diabetic foot is recommended depending on risk category.

Patient education for foot care at home is also plays a very vital role in prevention of foot ulcers. Simple guidelines regarding use of right footwear, walking techniques, use of cosmetics, trimming nails, etc can ensure that the patient is well-informed and cautious about their feet.
