Diabetes is a chronic disease affecting the blood sugar levels and it has the risk of affecting eyes, heart and kidneys. It has the power to reduce the immune system of your body and hence foot problems develop commonly in people with diabetes. Owing to the damaged nerves, the individual may fail to notice his feet and gradually it may turn into serious problem causing sores. There will be intense pressure on the foot when the normal lubrication is disturbed and this may cause pressure on the joints of the foot.
Since the blood vessels are already damaged even a small wound in any part of the body may take time to heal in diabetes patient. Due to the bacterial infection on the muscles and tissues even antibiotics may not help in controlling the disease. If the condition becomes severe the only option left is to amputate the foot or toe which is severely damaged.
There are several factors which causes diabetes foot. Improper footwear like tight fitting shoes can increase the chance of infection. The diabetes patient should take enough care in using right pair of shoes or slippers and should regularly examine his or her foot for any changes or sores. Individuals who cannot control their diabetes problem will often be having damaged nerve cells in their feet. This condition is called peripheral neuropathy and he may not be able to sense any pain or rubbing action on his feet. This is one of the major causes for diabetes foot since the patient will fail to notice any sores, blisters or minor injuries on his feet. The blood flow is affected you cannot expect the area to heal quickly. Smoking is also another important cause for the development of damaged blood vessels which in turn causes diabetes foot.
There may be blisters, sores, and injuries on the leg of feet. Sometimes the patient may feel intense pain in the areas surrounding the wound. The entire area which is infected develops inflammation. Swelling of the feet is a definite sign of damaged blood vessels or infection. Due to reduced nerve functions, hair may not grow on the area. You can observe pus or liquid discharge from the wound suggesting infection. Some persons may have difficulty in walking which indicates that infection has become serious.
The doctor examines the condition of the infected wound and prescribes antibiotics to kill the bacteria and to control the infection. If needed, he may refer the case to orthopedic surgeon for correcting the bone related problems. In some cases surgery may be done for removing the wound and for facilitating improved blood flow. If the infection is very serious and spreading to other parts then amputation is the only option for diabetes foot.
