Unexplained bruises—especially on arms, legs, or torso—can be more than just “aging.” While occasional bruising is normal, sudden or frequent bruises, especially with other symptoms, may signal serious health issues.
Major causes include blood disorders like low platelets or leukemia (large bruises, petechiae, nosebleeds, fatigue), medication side effects (blood thinners, steroids causing easy bruising), vitamin deficiencies (C or K, slow-healing bruises, bleeding gums), autoimmune attacks (lupus, vasculitis causing bruises along vessels, joint pain, rashes), and liver disease (abdominal bruises, jaundice, swelling).
“Natural remedies” like cabbage leaves or arnica may reduce surface bruising but do not address underlying conditions. If you notice unexplained bruises, track them with photos, check for new medications, and request tests including CBC, PT/INR, and liver panels.
Seek immediate care for bruises with petechiae, blood in urine/stool, confusion, or after minor head injury. Protect blood vessels with vitamin C and K, avoid unnecessary blood thinners, and get screened regularly. Dismissing sudden bruising as normal aging can hide serious, treatable conditions—your body is signaling when something is wrong, and early attention can save lives.
