Why Do I Bruise So Easy? Understanding the Causes and When to Worry

If you notice bruises appearing more often than usual, and with minimal injury, you may be wondering about the reasons behind it. This article explores the common causes of easy bruising, from aging to medications, and guides you on when it’s important to seek medical advice. By Mayo Clinic Staff

Have you recently spotted a bruise and can’t recall any specific bump or injury that caused it? It might seem like bruises are appearing more frequently lately. Many people experience this, and it leads to questions about whether easy bruising is normal or a sign of an underlying health issue.

Bruising easily is a common experience, particularly as we age. In most cases, these bruises are harmless and will disappear on their own without any treatment. However, it’s important to understand that sometimes, easy bruising can indicate a more serious health concern that requires attention.

Why Does Bruising Happen Easily, Especially as We Age?

Bruises occur when small blood vessels, known as capillaries, located close to the skin’s surface, are damaged. This damage is usually caused by a physical impact or injury, often to the arms or legs. When these capillaries break, blood leaks out into the surrounding tissue. This leaked blood is what initially creates the dark, visible mark of a bruise. Over time, the body naturally reabsorbs this blood, and the bruise gradually fades and disappears.

Generally, the harder the blow, the larger the bruise is likely to be. However, individuals who bruise easily might develop a significant bruise even from a very minor bump or seemingly insignificant injury.

It’s also worth noting that some people are naturally more susceptible to bruising than others. Women, for example, tend to bruise more easily than men. Furthermore, the aging process plays a significant role in easy bruising. As we get older, our skin undergoes changes, becoming thinner and losing some of the protective fatty layer that normally cushions our blood vessels. This reduced cushioning makes the blood vessels more vulnerable to injury, even from minor impacts.

Medications and Supplements: A Hidden Cause of Easy Bruising?

Certain medications can increase your tendency to bruise easily by affecting the blood’s ability to clot properly. These medications include common pain relievers like aspirin, ibuprofen (found in Advil and Motrin IB), and naproxen sodium (Aleve). Anticoagulant medications, often referred to as blood thinners, such as warfarin (Jantoven), dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis), and heparin, also have this effect. Additionally, anti-platelet agents like clopidogrel (Plavix), prasugrel (Effient), and ticagrelor (Brilinta), which prevent blood platelets from sticking together, can contribute to easy bruising. Even some antibiotics and antidepressants have been linked to blood clotting issues. When these medications are involved, even minor damage to small blood vessels near the skin’s surface can result in more blood leakage and a more prominent bruise because the blood takes longer to clot and stop flowing.

Corticosteroids, available in both topical and systemic forms, are used to treat various conditions like allergies, asthma, and eczema. These medications can also lead to easier bruising because they thin the skin, making blood vessels more susceptible to damage. Certain dietary supplements, such as ginkgo biloba, are also known to increase bruising risk due to their blood-thinning effects.

If you notice an increase in bruising, it’s crucial not to stop taking any prescribed medications without consulting your healthcare provider. Instead, discuss your concerns with them. It’s also important to inform your provider about any supplements you are taking, especially if you are also on a blood-thinning medication. Your provider can assess the situation and might advise you to avoid certain nonprescription medications or supplements that could be contributing to the problem.

When Easy Bruising Could Signal a More Serious Health Problem

While most easy bruising is not a cause for alarm, it can sometimes be an indicator of a more serious underlying medical condition. These conditions can include blood-clotting problems or blood diseases. It’s important to consult your healthcare provider if you experience any of the following:

• Frequent, large bruises: Especially if they appear on your trunk, back, or face, or if they seem to develop without any known injury.
• Easy bruising combined with a history of excessive or prolonged bleeding: For instance, prolonged bleeding after a minor cut or during surgical procedures.
• Sudden onset of easy bruising: Particularly if this starts shortly after beginning a new medication.
• Family history of easy bruising or bleeding disorders.

These symptoms might suggest underlying issues such as:

• Low platelet levels: Platelets are essential blood components that help the blood clot after an injury.
• Platelet dysfunction: Problems with how platelets function, even if the levels are normal.
• Clotting protein deficiencies: Issues with proteins that are necessary for proper blood clotting.

Another serious, though often overlooked, cause of unexplained bruising is domestic violence or abuse. If you notice unexplained bruises on a loved one, especially in unusual locations like the face, it is crucial to consider the possibility of abuse.

To determine the cause of your easy bruising, your healthcare provider will likely perform a physical examination and ask detailed questions about your symptoms and medical history. They might also order blood tests to check your platelet levels and assess how long it takes your blood to clot. These tests can help identify any underlying blood disorders or clotting problems.

Preventing Bruises and What to Do When They Occur

For minor bruising, prevention focuses on reducing the risk of falls and injuries. Here are some helpful steps:

• Ensure good lighting at home: Adequate lighting helps prevent accidents and bumps.
• Eliminate clutter and throw rugs: Especially on stairs, as these can be tripping hazards.
• Arrange furniture and electrical cords: Keep walkways clear to avoid tripping.
• Understand medication side effects: Be aware if any medications you take can cause dizziness or sleepiness, and discuss alternatives with your healthcare provider or pharmacist if needed.
• Regular vision and hearing tests: Even slight changes in sight or hearing can increase the risk of falls.

Unfortunately, once a bruise has formed, there isn’t much you can do to make it disappear faster. Most bruises will naturally fade as the body reabsorbs the leaked blood. However, this healing process can take longer as you age. To manage discomfort and potentially reduce swelling, you can try elevating the bruised area and applying ice packs.

For any concerns about easy bruising, especially if accompanied by the symptoms mentioned earlier, consulting a healthcare professional is always the best course of action to ensure your health and well-being.
