Quite often, a diabetic patient takes no notice of small scratches, small blisters, injuries which do occur to the leg in day-to-day life. This small scratches gets converted into full-fledged ulcer if not treated properly in time. Normally in a non-diabetic person these ulcers heal well after repeated dressings and antibiotic applications.
But in a diabetic patient, these ulcers generally do not respond to such treatment. Because of ignorance of this fact, a diabetic patient does not take the leg ulcer, which otherwise looks simple, seriously and this result in a serious complicated condition of the leg.
Due to diabetic neuropathy, in diabetic patients the sensitivity of leg and foot skin is considerably decreased. Because of reduced skin sensitivity, a diabetic patient never feels the sensation of pain, which a normal non-diabetic person otherwise feels in case of pressure abrasion and superficial simple injury. One more reason for the development of pus and gangrene in the foot ulcer of a diabetic person is the inadequate blood supply to the foot due to a narrowing of arteries of the lower limbs, which carry pure blood to the feet.
Must do-s to prevent foot ulcers in a diabetic patient:
Get your legs and feet checked up once by a vascular or a cardiovascular surgeon for evaluation of leg arteries and its blood supply, even if you have no complaints. Keep your blood sugar under control either by insulin injection or oral anti-diabetic drugs, under strict guidance of a diabetologist or your own local doctor.
Never walk barefoot, even inside your house. Avoid wearing chappals, slippers and sandals. Never expose your feet and toes to outside injuries and to extreme cold during winters. Keep your feet warm and covered with socks. Keep your feet dry and clean. Never allow moisture or water to stay inside the spaces between the toes.
Avoid wet and sweaty socks. Clean your feet, toes and toe-spaces twice daily with methylated spirit and then sprinkle Neosporin powder on toes and in the spaces between the toes. Inspect your feet daily, look for abrasions, blisters, raw area and thickened skin. Consult your surgeon and seek his advice.
Avoid tight and uncomfortable shoes. Discard the shoes immediately, which bite your feet. Never smoke, because tobacco in any form is injurious to your diabetic feet. Keep your weight under check. Obesity is very harmful to your legs. Lastly, never shave off any corn developed on your feet.
