There are different types of leg ulcers, and the classifications are based on which blood vessels or nerves suffered damage. Knowing what causes the ulcers on your legs will help you determine whether what you have is a cause for alarm.
Acute vs. Chronic
The acute leg ulcer is often a result of accident, trauma, or surgery. The healing process can last up to four weeks. On the other hand, a chronic leg ulcer does not heal as fast as the acute ones. It is complicated, and the common causes are due to internal problems.
Damage to the veins causes this kind of ulcer. The common reason for this is a blood clot (thrombosis) that leads to the abnormal blood flow in your legs. If your blood flows abnormally in your legs, it will cause high pressure that can damage the skin, causing the ulcer.
People who are at risk are those with varicose veins, thrombosis, and those who are obese.
This type of ulcer is also known as an ischaemic ulcer. From the name itself, the ulcer is caused by problems in the arteries, mainly due to the lipid or cholesterol deposits clogging them. For this reason, the blood and the oxygen cannot flow freely to the tissues, thus causing the ulcer.
People who are at risk are those with diabetes, obesity, rheumatoid arthritis, and arterial diseases. People who smoke are also at risk.
The ulcer is caused by people being unaware that they have an open wound due to the damage to their peripheral nerves. It is the common type of ulcer found in people with diabetes. The symptoms include numbness, pain, or tingling sensation.
People who are at risk are those with diabetes, tumors, and autoimmune diseases.
Leg ulcers may look simple at first, but it may lead to serious complications like gangrene. For this reason, you should have your leg ulcer treated before it becomes worse enough that it already needs to be amputated.
