What are the causes of Ulcers?

There are a number of causes, but for the most part ulcers can be categorized into three part
ulcers can be categorized into three major causes.

1. Ulceration due to loss of sensation (neurotropic)

2. Ulceration due to poor circulation entering the foot (arterial) or exiting the foot and leg (venous)
3. Ulceration due to pressure (bed sores)

Ulcers can be the result of any combination of these three major causes. A variety of diseases, such a diabetes, arteriosclerosis, venous disease, leprosy, alcoholism, rheumatoid arthritis, gout, syphilis and strokes, can also cause ulcerations of the foot and leg.

Along with the above causes, presser and injury to the skin can be precipitating factors in ulcer formation. The combination of pressure on an abnormal bony prominence and ill-fitting shoes can result in skin breakdown or ulceration. The problem then becomes the ulcer, opening the door for bacteria to enter the body and trigger infection. In conjunction with poor circulation or diabetes, this skin loss or open area could develop into a limb-threatening infection.
