Many people are alarmed when they have bruises even if they know why they have them. So much more when they don’t know what caused the bruising. Unexplained bruising is as common as any other type of bruises and it could affect children and adults. Bruises can appear anywhere in the body. More often, the location can help explain why a person has an unexplained bruise.
Bruises are a result of blood coming from damaged blood vessels that rise to the skin surface. They may appear as black, blue or a combination of both colors. Generally, it takes about two to four weeks before a bruise can completely heal. During healing time, it could also change in color from reddish blue to yellowish green or brown in appearance.
One of the most common parts of the body where bruises frequently occur is the legs. A lot of factors may cause a person to have unexplained bruises in the legs and some of them are more serious than others. If the bruising is caused by a serious health condition, early detection could be life-saving.
For athletes such as those involved in track and field, unexplained bruises could be a result of several factors. One of them is injury during practice. Minor injuries that go unnoticed sometimes result to bruising after a few days and the person concerned may have already forgotten what has caused it. Sometimes, strenuous activities can also damage the blood vessels, resulting to bruising.
Among elderly people who like to run, a common cause of unexplained bruising is too much exposure to direct sunlight. UV rays can damage blood vessels resulting in skin redness or bruises. Also, as a person ages, the connective tissues become weaker such that even minor trauma can result to bruises.
Certain medications such as ibuprofen and aspirin affect the ability of the blood to clot, thereby producing bruises. Corticosteroids and birth control pills also cause inflammation in blood vessels and tissues resulting in leakage of blood that appears on the surface of the skin as bruises.
There are also underlying health conditions that can lead the body to produce bruises. One of them is deficiencies in Vitamins C, K and B12 and folic acid. People with longstanding diabetes are also more prone to developing bruises which are normally dark-colored and usually appear around the neck and other body folds. A blood disease such as sepsis, hemophilia, Hodgkin’s disease, leukemia, platelet dysfunction and blood cancers may also result to excessive bruising. Other medical conditions that can cause bruising are Graves’ disease, Ehlers-Danlos syndrome, and lupus. More often, a person is not aware of his more serious health condition and it is only diagnosed after testing for unexplained bruises.
Unexplained bruises in the legs for track and field athletes may be caused by various factors. Some of them are really serious and deserve immediate medical attention. If you constantly have bruises on the legs and you cannot explain why, it is best to let your doctor examine you for proper diagnosis.
