Factors influencing the tendency to bruise

Several factors contribute to the tendency to bruise, such as age (older people are more prone to bruising as their skin thins and blood vessels become fragile), sex (women may be susceptible to bruising more than men), and individual differences in blood vessel structure and density.

An excessive tendency to bruise, occurring without a clear cause and potentially associated with the sensation that bruises appear spontaneously, can suggest a health issue that requires medical consultation.

Three conditions that a bruising tendency can suggest


Anemia is a condition characterized by an inadequate number of red blood cells or insufficient hemoglobin in these cells, making it challenging to deliver oxygen throughout the body's tissues. People with anemia might find that their bruises seem to appear more quickly or become more noticeable due to pale skin.

Anemia is treated depending on its cause, type, and severity. The most frequent forms of anemia are caused by deficiencies (iron, vitamin B12, folic acid), while hemolytic and aplastic anemia are rarer.


Thrombocytopenia is a condition denoted by a low number of blood platelets. Given that these blood platelets are crucial in blood clotting, a deficiency can lead to easy bruising and bleeding.

Thrombocytopenia could be due to a lack of vitamin B12 and folic acid. Remarkably, it can also be a symptom of leukemia or kidney failure.

Blood clotting disorders

Blood clotting disorders include a group known for increased tendencies to bleed (hemorrhagic diathesis) and conditions where the blood tends to form excessive clots (thromboembolic diathesis).

Hemorrhagic and thromboembolic diathesis can both manifest themselves as a bruising tendency, although the reasoning behind these bruises is different. Both types of bleeding disorders require accurate diagnosis and treatment to mitigate the risk of serious complications.

Medication's impact on bruising

Certain medications can heighten the likelihood of bruising. For instance, anticoagulants (such as warfarin or heparin) and antiplatelet drugs (like aspirin or clopidogrel) decrease the blood's ability to clot, increasing the likelihood of bruising.

Some steroid medications may also augment the tendency to bruise due to their effect of increasing the fragility of blood vessels.

An excessive tendency to bruise, notably when accompanied by other symptoms such as chronic fatigue or bleeding from the nose or gums, should provoke discussion with a doctor. The causes could include the abovementioned conditions and other disorders requiring an accurate diagnosis and treatment.
