Bruising in older adults

Overview

A bruise is a mark on your skin caused by blood leaking from tiny blood vessels under the surface. In older adults, this happens more easily because the skin gets thinner and blood vessels become more fragile.

Yes, bruising is very common in older adults. Up to 1 in 3 older people will have bruises regularly.

It mainly affects adults over 65, especially those on blood‑thinning medicines or with fragile skin.

Symptoms

Common symptoms

• Black‑and‑blue or purple marks on the skin
• Tenderness or mild pain in the bruised area
• Swelling around the bruise

Symptoms in older adults

• Bruises often appear on the arms, hands, legs and back
• Bruises can be larger and take more than two weeks to fade
• Skin may feel thin or papery around the bruise

Causes

Main causes

• Thinning of the skin and weakening of blood vessels due to ageing
• Medicines that affect blood clotting, such as blood thinners or anti‑inflammatory drugs
• Vitamin C or Vitamin K deficiency
• Liver disease or blood disorders that affect clotting

Risk factors

• Being over 65 years old
• Taking medicines like aspirin, warfarin, or clopidogrel
• Sun‑damaged skin from years of sun exposure
• Poor nutrition or unintended weight loss

When to see a doctor

See a doctor urgently if:

• If you have a large, painful bruise that appears without injury
• If you have easy bruising with bleeding from other parts of the body

Book a routine appointment if:

• If you notice new, frequent bruises and want to check what is normal
• If you are on a blood‑thinning medicine and are concerned about your bruising pattern
• If you have symptoms of a vitamin deficiency, like tiredness or pale skin

Diagnosis

Your doctor will examine the bruises and ask about your medical history, medicines, and any recent injuries. They may also take a small blood sample to check your blood clotting and vitamin levels.

Tests that may be done

• Blood test to measure bleeding time and platelet count
• Vitamin C and Vitamin K level tests
• Liver function tests if other signs are present

What to expect at your appointment

The doctor will listen to your concerns and explain likely causes. Usually no treatment is needed, but if an underlying condition is found, they will discuss next steps with you.

Treatment

For most older adults, treatment is not needed. Proper self‑care and avoiding further bumps is enough. If a cause is found, treatment will focus on that.

Self-care at home

• Apply a cold pack (wrapped in a cloth) to the bruise for 10–20 minutes to reduce swelling
• Elevate the bruised area if possible
• Keep the skin moisturised with a gentle cream to reduce fragility
• Avoid activities that might cause more bumps or falls

Medical treatments

If bruising is linked to a medicine, your doctor may adjust the dose or suggest a different option. For vitamin deficiencies, supplements may be recommended. Any treatment will be tailored to your individual situation – always follow your healthcare provider’s advice.

When is surgery considered?

Surgery is not a treatment for ordinary bruising. Rarely, if a large bruise becomes very swollen and painful (a haematoma), a doctor may need to drain it. This is uncommon.

Living with this condition

You can manage bruising by being mindful of your surroundings. Use rails, keep floors clear of clutter, and wear long sleeves or trousers to protect your skin. Check your skin after any bump to see if a bruise forms.

Lifestyle tips

• Stay active with gentle exercises like walking or swimming to keep muscles strong and reduce fall risk
• Wear well‑fitting shoes with non‑slip soles
• Use good lighting at night

Diet and exercise

A balanced diet with plenty of fruits and vegetables – especially those rich in vitamin C (oranges, strawberries, broccoli) and vitamin K (leafy greens like spinach and kale) – may help your skin stay healthy. Gentle exercise improves circulation and strength.

Mental health and emotional wellbeing

Seeing new bruises can be worrying and may cause you to feel anxious about your health or appearance. It is normal to feel this way. Remind yourself that most bruises are harmless, but speaking with your doctor can ease your mind.

Prevention

You cannot fully prevent bruises as you age, but you can lower your risk. Protect your skin, avoid bumping into furniture, and use padding (like elbow or knee pads) during activities. Keep your home free of tripping hazards.

Complications

If left untreated

• If underlying bleeding or clotting problems are missed, they could become more serious
• Severe vitamin deficiencies can lead to anaemia or poor wound healing
• A large collection of blood (haematoma) may need medical drainage

Long-term outlook

For the vast majority of older adults, bruising is a normal part of ageing and does not cause any long‑term problems. If a cause is found, it can usually be treated or managed. Taking simple precautions can help you stay active and independent.
