Bruising or ecchymosis is caused by burst capillaries beneath the skin's surface, resulting in trapped blood and discoloration. While it can happen to anyone at any age, older adults are more likely to develop bruises. Another cause is exercise, especially during weight training, where repetitive movements can cause minor bruising. In these cases, resting, hydration, and time help the injury to heal on its own. However, sometimes unexplained, random bruising is due to serious conditions that require in-depth diagnosis and specialized treatment.

1. Chemotherapy

Chemotherapy is the use of chemicals to treat the rapid growth and division of cells that cause cancer. The solution works its way throughout the body and doesn't discriminate in what it affects, including the healthy parts. As a result, it can lower blood platelet count, reducing the body's ability to clot. People undergoing chemo are advised to stop taking certain medicines, such as over-the-counter painkillers that thin the blood. They are also warned to prevent bleeding by moisturizing chapped skin and using softer toothbrushes.
