Hello, I'm an expert in the field of medical science. I'd be happy to explain why ecchymosis occurs.

Ecchymosis, also known as a bruise, is caused by bleeding beneath the skin that results from an injury. When blood vessels, particularly capillaries and veins, are damaged due to trauma, they can leak blood into the surrounding tissues. This blood then pools and causes the discoloration and swelling that we recognize as a bruise. The severity and size of the ecchymosis can vary depending on the extent of the injury and the individual's response to it.

Several factors can influence the occurrence of ecchymosis, including:

1. Age: As we age, our skin becomes thinner and less elastic, making it more susceptible to bruising.

2. Gender: Women tend to bruise more easily than men due to hormonal differences that affect the blood vessels.

3. Medications: Certain medications, such as blood thinners or corticosteroids, can increase the likelihood of bruising.

4. Nutritional deficiencies: A lack of certain vitamins and minerals, like vitamin C or K, can weaken blood vessels and make them more prone to rupture.

5. Underlying health conditions: Conditions like hemophilia or other clotting disorders can also lead to ecchymosis.
