Bruising easily
Bruises that appear with little or no injury, or seem larger or more frequent than expected — often harmless and related to ageing skin or medicines, but sometimes a sign of a clotting, blood or liver problem that needs checking.
Education and reference only. This explains the common causes of bruising easily and the warning signs that need urgent help, in plain language — it is not a diagnosis or a substitute for advice from a clinician. If you feel very unwell or are worried, seek medical help.
Quick answer
What is bruising easily?
Bruising happens when small blood vessels under the skin leak after a knock, leaving a patch that changes colour as it heals. Bruising more easily than before — getting bruises from minor bumps you cannot even recall, or finding them in unusual places — is common and often harmless.
- Get urgent help: Call 999 if bruising or tiny red or purple spots appear with a fever and a rash that does NOT fade when you press a glass against it — this can be meningococcal infection. Seek urgent same-day help for sudden, widespread or unexplained bruising, especially with pinpoint blood spots, bleeding gums or nosebleeds.
- Self-care: If a clinician has checked you over and found no worrying cause, easy bruising linked to ageing skin or sun damage can be managed with simple, sensible measures.
About bruising easily
Bruising happens when small blood vessels under the skin leak after a knock, leaving a patch that changes colour as it heals. Bruising more easily than before — getting bruises from minor bumps you cannot even recall, or finding them in unusual places — is common and often harmless. Thinner, more fragile skin with age, sun damage over the years, and blood-thinning or steroid treatments all make bruises appear more readily. What matters is spotting the smaller number of cases where easy bruising reflects something deeper. A problem with the platelets or clotting system, a bone-marrow disorder, or liver disease that impairs the production of clotting factors can all show as easy bruising. The pattern to take seriously is bruising that appears suddenly and widely, comes with tiny pinpoint red or purple spots, is joined by bleeding gums or nosebleeds, or arrives with fever or extreme tiredness — and, crucially, a non-blanching rash that does not fade when pressed, which is a medical emergency.
When to get help
Call 999 or go to A&E if bruising easily comes with any of these warning signs:
- Call 999 if bruising or tiny red or purple spots appear with a fever and a rash that does NOT fade when you press a glass against it — this can be meningococcal infection.
- Seek urgent same-day help for sudden, widespread or unexplained bruising, especially with pinpoint blood spots, bleeding gums or nosebleeds.
- Seek urgent help for easy bruising with extreme tiredness, repeated infections, fever or unexplained weight loss — these can point to a blood disorder.
- Seek urgent help for bruising with bleeding that will not stop, blood in the urine or stool, or a very heavy period.
- See a doctor promptly for new easy bruising after starting a medicine, or with yellowing of the skin or eyes.
When to see a doctor
Easy bruising in someone with thin, ageing or sun-damaged skin, or who takes a blood-thinning or steroid treatment, is usually not dangerous but is worth mentioning at a routine appointment. Seek urgent assessment if bruising appears suddenly and widely, comes with pinpoint blood spots, bleeding gums, nosebleeds, fever, repeated infections, extreme tiredness or weight loss, as these can signal a clotting or blood disorder needing a blood test. Yellowing of the skin or eyes alongside bruising points to the liver. And call 999 for any non-blanching rash — spots that do not fade under a pressed glass — especially with a fever, as this can mean meningococcal infection.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
What can cause it
Common causes of bruising easily
Bruising easily has many possible causes. Each links to a full, plain-language guide to that condition — what it is, how it's treated and when to seek help.
What helps
Self-care and what you can do
If a clinician has checked you over and found no worrying cause, easy bruising linked to ageing skin or sun damage can be managed with simple, sensible measures. Protect fragile areas such as the forearms and shins by being careful around furniture, wearing long sleeves and trousers where practical, and arranging the home to reduce knocks. Protect your skin from the sun over the long term to limit further fragility. If you take a blood-thinning or steroid treatment, do not stop it on your own, but do mention increased bruising to your clinician. Eat a balanced diet to support healthy skin and blood. Keep an eye out for the warning features below, as easy bruising sometimes needs a blood test to be sure all is well.
Answers
Bruising easily: frequently asked questions
Why do I bruise more easily than I used to?
Skin becomes thinner and more fragile with age and sun damage, and blood-thinning or steroid treatments make bruises appear more readily. This is usually harmless, but sudden, widespread or unexplained bruising should be checked.
When is easy bruising a sign of something serious?
Be concerned if bruising appears suddenly and widely, comes with pinpoint red or purple spots, bleeding gums or nosebleeds, fever, extreme tiredness or weight loss. This pattern can point to a clotting or blood disorder and needs an urgent blood test.
What is the glass test?
Press a clear glass firmly against a rash or spots. If they fade, it is reassuring; if they do NOT fade under pressure, this is a non-blanching rash that, especially with a fever, can mean meningococcal infection — call 999.
Can liver problems cause bruising?
Yes. The liver makes clotting factors, so liver disease — from heavy alcohol use or hepatitis — can impair clotting and cause easy bruising and bleeding, sometimes with yellowing of the skin or eyes. This needs medical assessment.
