What Causes Foot Ulcers?

Diabetes can damage the nerves and blood vessels in your feet. This damage can cause numbness and reduce feeling in your feet. As a result, your feet are more likely to get injured and may not heal well if they are injured. If you get a blister, you may not notice and it may get worse.

If you have developed an ulcer, follow your health care provider’s instructions on how to treat the ulcer. Also follow instructions on how to take care of your feet to prevent ulcers in the future. Use the information below as a reminder.

The Top 4 Causes Of Dangerous Foot Ulcers

There are several medical conditions in podiatry that can result in frequent or non-healing wounds to the feet . Diabetes is one of the most common, but there are others, such as peripheral neuropathy, atherosclerosis, and Raynaud’s phenomenon. Without going into the scientific differences of these medical issues, there are four main reasons that ulcers form and get worse.

From Injury Or Blister To Ulcer

If a person with decreased sensation gets a blister or other injury, they may not notice it and it can develop into an ulcer.

Neuropathy:Neuropathy is a general term for nerve dysfunction. Peripheral neuropathy is the most common type of neuropathy in people with diabetes and typically affects the nerves of the feet, legs, and sometimes the arms and hands.

People with diabetes are at increased risk for peripheral neuropathy if they have a history of hyperglycemia and have had diabetes for a long time. Other risk factors for neuropathy include smoking and genetic predisposition.

Over time elevated blood sugar levels can affect nerve functioning and nerve signaling. Small nerve dysfunction results in the inability to feel pain, and large fiber dysfunction causes disturbances in balance, which can increase the risk of falls.

If a person has neuropathy and injures their foot without feeling it, they may not notice it until it gets much worse. Recurrent, unnoticed injuries to the foot can increase the risk of Charcot foot, in which progressive destruction of the bones and joints leads to foot deformity.

Autonomic neuropathy can cause a decrease in sweating, resulting in dry feet. Having dry feet can increase the risk of developing calluses. While calluses are healthy, if you have lost sensation, they can grow deeper cause damage to the skin surface known as breakdown, putting the foot at risk of blisters or ulcers.
