Bruises occur when something bumps into the skin of an individual or they bump into it. This causes rapture to tiny capillaries beneath the skin. The area affected by the rapture is usually darkened. There are individuals whose skins are easily bruised than others. This could be due to poor health, fragile capillaries or inability of such skins to produce collage. For such people, bruises may appear without any apparent cause. Studies also reveal that individuals with frequent bruising could be lacking some nutrients. These could be Vitamin C, E and K. Lack of bioflavonoid and also Zinc may cause easy bruising.
Nevertheless, there are major causes of bruises that are common in many people.
- Bruising may occur in some individuals who engage in rigorous exercising. These include weight lifters and athletes. Such bruises may be as a result of microscopic tears that occur in blood capillaries beneath the skin. In athletes, bruising can occur due to direct trauma or impact and hematoma might accompany it.
- Bleeding disorder can be another cause of bruising in some individuals. This is a form of bruising that does not have any apparent cause. It is caused by blood-thinning medications also called anticoagulants. These bruises are usually accompanied by bleeding gums and nosebleeds.
- There are cases when bruises results from bumping into objects or a bedpost. This may cause a bruise on the thigh or shin.
- In aged persons, bruising may result from thinning of the skin. This usually happens as someone age and the skin is usually left without the ability to support blood capillaries beneath it. These capillaries are also fragile and a minor injury can easily cause damage on them resulting to internal bleeding.
- Bruising may also be an indication of child physical abuse.
