Chapter 2: Common Causes of Unexplained Bruising
Many everyday factors can make bruising more likely. Aging naturally causes the skin to become thinner, making blood vessels more vulnerable to damage. Certain medications, including blood thinners and some anti-inflammatory drugs, may also increase bruising.
Nutritional deficiencies can sometimes play a role as well. Low levels of vitamins such as vitamin C or vitamin K may affect the body's ability to repair blood vessels and support normal clotting functions.
Physical activity is another common cause. People who exercise regularly may experience small injuries they do not immediately notice. By the time a bruise appears, the original cause may have been forgotten.
Because bruising can result from so many factors, medical professionals generally avoid making assumptions based on appearance alone. A careful assessment of symptoms and medical history provides a much clearer understanding of what may be happening.
Chapter 3: When Bruises May Require Medical Attention
Although most bruises are harmless, there are situations where medical evaluation may be appropriate. Experts often recommend paying attention if bruises appear frequently without injury, become unusually large, or are accompanied by other symptoms.
