Why the sore does not heals in the sugar patients?

Answer:
Diabetes is not just increased blood sugar. IT affects practicaaly all parts of the body! It can cause damage to the nerves so the patient loses feeling in his feet leading to small cuts occuring while walking. Due to the increased blood sugar, the bacteria are provided with a fertile breeding ground. diabetes also leads to accelerated atherosclerosis which causes narrowed blood vessels therby reducing the entry of WBCs, antibodies and antibiotics to the site of infection. Also the nutrients needed for building up new tissue in the healing process is prevented access to the wound site due to the impaired blood supply. Due to all these causes treating a diabetic foot is complicated and may sometimes end in amputation.
