What Is Bruising?
Bruising, also called a contusion, occurs when small blood vessels beneath the skin break because of an injury or impact. Blood leaks into the surrounding tissues, causing discoloration that typically changes from red or purple to blue, green, yellow, and brown as the bruise heals.
Most bruises are minor and heal on their own within a few weeks, but frequent or unexplained bruising may indicate an underlying medical condition.
Why Bruising Matters
Although bruises are often harmless, they can sometimes signal bleeding disorders, medication side effects, nutritional deficiencies, or more serious injuries. Older adults may bruise more easily because their skin and blood vessels become more fragile with age.
Common Causes of Bruising
- Minor falls or bumps
- Sports injuries
- Blood-thinning medications
- Aging
- Bleeding disorders
- Vitamin C or vitamin K deficiency
- Certain medical conditions affecting blood clotting
Common Symptoms
- Purple, blue, or black skin discoloration
- Tenderness at the affected area
- Mild swelling
- Pain when pressure is applied
- Gradual color changes as healing occurs
How Is Bruising Evaluated?
Healthcare providers usually diagnose bruising through a physical examination and medical history. If bruising is frequent, severe, or unexplained, blood tests or additional evaluations may be recommended to identify underlying causes.
How Is Bruising Treated?
Most bruises improve with rest, ice, compression, and elevation (RICE) during the first 24 to 48 hours. Larger or more painful bruises may require medical evaluation, especially if they are associated with significant swelling or limited movement.
How Home Care Can Help
Home care professionals help reduce fall risks, assist with safe mobility, monitor bruises for changes, encourage proper nutrition, and report unusual or worsening bruising to the healthcare provider.
Home Care Tip
If you take blood-thinning medication, inspect your skin regularly for new bruises and report any unusual or unexplained bruising to your healthcare provider.
Frequently Asked Questions About Bruising
Why do older adults bruise more easily?
As people age, the skin becomes thinner and blood vessels become more fragile, making bruising more common after even minor injuries.
When should bruising be evaluated by a healthcare provider?
Medical evaluation is recommended for frequent unexplained bruising, very large bruises, bruises that do not improve, or bruising accompanied by unusual bleeding.
Can home care professionals help prevent bruising?
Yes. Home care professionals reduce fall risks, assist with mobility, monitor skin health, and help create a safer home environment to minimize injuries.
When to Seek Immediate Medical Care
Seek immediate medical attention if bruising follows a head injury, is associated with severe pain or swelling, occurs with uncontrolled bleeding, or is accompanied by dizziness, confusion, or loss of consciousness.
