Understanding Bruising in Elderly Skin - Causes, Pictures, Prevention

Understanding Bruising in the Elderly

As we age, our skin undergoes natural changes that can make it more susceptible to bruising. Bruising occurs when small blood vessels under the skin rupture, allowing blood to pool and cause discoloration. For the elderly, bruising may occur more frequently and take longer to heal.

There are several reasons why seniors bruise more easily. With advanced age, the skin becomes thinner and loses some of its protective fatty layer. Veins and tiny capillaries under the skin become more fragile. Seniors also have decreased muscle mass, which means there is less cushioning to protect blood vessels if bumped or knocked.

Certain medications commonly used by older adults, such as blood thinners, aspirin, and steroids, can also interfere with blood clotting and lead to increased bruising. Chronic health conditions like diabetes, kidney disease, and autoimmune disorders may also contribute.

Common Locations for Bruising in the Elderly

Bruises can occur anywhere on the body, but there are several key areas where seniors tend to develop bruises most frequently:

• Arms - Age-related loss of fat and muscle tone in the arms means impacts cause easier bruising.
• Legs - Bruises are common on older legs, especially around the shins and knees.
• Hands - Prominent veins and thinning skin on the hands lead to noticeable bruises from minor bumps.
• Feet - Bruises often develop across the tops of feet or heels in the elderly.

Bruising may also frequently occur in areas that receive regular pressure or impact like the hips, tailbone, elbows, and shoulders. Seniors are also prone to bruising during blood drawing or injections in their hands, arms, and feet.

Signs and Symptoms of Bruising

Bruises can range in severity but often share the same basic signs and symptoms:

• Discolored or darkened patch of skin
• Skin tenderness, soreness, or pain
• Swollen or raised area
• Visible bleeding under skin

The discoloration reflects bleeding under the skin in shades of blue, purple, yellow, green, or brown. More severe bruises may be accompanied by significant swelling, hard knots, or pain.

Causes and Risk Factors for Bruising

Common causes and risk factors for bruising in seniors include:

• Falls or impacts
• Medications - Blood thinners, aspirin, steroids
• Thinning skin
• Sun damage
• Dehydration
• Poor nutrition - Vitamin C, Vitamin K deficiency
• Leukemia or blood disorders
• Unexplained bruising - Signs of abuse or neglect

Minor bumps and knocks that previously would not have caused bruising may now leave discoloration and swelling. Activities like gardening, cooking, cleaning, and dressing may lead to small bruises, especially on the hands and arms.

When to See a Doctor

Occasional minor bruising is normal, but seniors should seek medical care if they experience:

• Bruising without an apparent cause
• Extensive or large bruises
• Bruises accompanied by bleeding
• Repeated bruises over time
• Bruises that do not improve with standard care

Unexplained bruising or bruising that seems excessive for an injury may indicate an underlying medical condition requiring treatment. Bleeding disorders, blood cancers like leukemia, blood clotting issues, and certain medications can increase bruising risk.

What Do Bruises Look Like on Elderly Skin?

Bruises often appear differently on an older person’s body compared to a younger person. Some key characteristics of bruises in the elderly include:

• Color - Bruises may appear darker and more purple-blue because the skin is thinner.
• Size - Bruises often appear larger on older individuals.
• Shape - Bruises can take on irregular shapes and appear in clusters.
• Location - Develops easily on exposed areas like hands, arms, legs, feet.
• Healing time - Bruises tend to take longer to fully heal and fade.

Colors and Stages of Bruise Healing

Like bruises on younger individuals, bruises on seniors go through color changes during the healing process:

• Reddish - Fresh bleeding under skin.
• Blue or purple - One to five days old.
• Green or brown - Five to ten days old.
• Yellow - Ten to fourteen days old.
• Fading yellow or brown - Two weeks old and healing.

However, each phase may last longer in an aging body. For example, purplish discoloration can persist for up to two weeks before fading to green.

Size and Shape

Bruises may appear noticeably larger on an elderly person, sometimes spreading or appearing in clusters. Minor impacts can cause bruises of extensive size.

Irregular bruise shapes are also common, appearing discolored and faint in the middle with darker outlining. Bruises may reflect the shape of an object, like a handprint or the pattern of a floor tile.

Location

Areas most vulnerable to bruising tend to be exposed sites with thinner skin and little fat or muscle padding:

• Dorsal hands
• Forearms
• Lower legs
• Feet

Bony areas like knees, elbows, hips, tailbone, and shoulders become more prone to bruising from falls or pressure.

Preventing Bruising in the Elderly

While some bruising may be inevitable, there are ways for older adults to reduce their risk:

• Use walking aids to prevent falls.
• Install grab bars and railings around the home.
• Wear protective gear like knee pads or shin guards.
• Treat and improve balance issues.
• Exercise to build muscle and improve mobility.
• Have vision checked and update prescriptions.
• Improve home lighting.
• Remove fall hazards like loose rugs.

Making adjustments to increase safety and stability can help limit bruising from impacts and falls. Consulting with a doctor to adjust medications that impair coagulation or thin the blood may also reduce bruising potential.

Nutrition and Lifestyle Changes

Eating a balanced diet rich in vitamins and minerals important for skin health can support bruise prevention. Key nutrients include:

• Vitamin C - Helps build collagen to maintain skin integrity.
• Vitamin K - Assists with proper blood clotting.
• Bioflavonoids - Help strengthen blood vessels.
• Zinc - Supports wound healing.

Staying hydrated, quitting smoking, protecting skin from the sun, and avoiding medications like steroid creams can also improve skin's resilience.

Home Treatment for Bruises

To help a bruise heal, standard home care techniques include:

• Resting and icing area to reduce swelling.
• Gentle compression with bandage or wrap.
• Elevating bruised limbs.
• Over-the-counter pain relievers.
• Applying cold compresses.
• Massaging bruise margins to improve circulation.
• Topical arnica cream.

Avoid hot compresses or activities that put strain on the bruised area. See a doctor if bruises do not fade within two weeks or new bruises continue appearing.

When to Worry About Bruising

While minor bruising may not be concerning, it is important for seniors and caregivers to watch for the following warning signs:

• Unexplained bruises - Bruises occurring without an injury or apparent cause.
• Widespread bruising - Extensive or clustered areas of bruising.
• Rapid or excessive bruising - For minor impacts or injuries.
• Bleeding into skin - Blood pooling under skin or leaking from cut.
• Prolonged healing - Bruises staying for weeks without fading.
• Painful bruises - Significant pain, swelling, or hardness.

Unusual bruising patterns like this may reflect an underlying medical condition and warrant evaluation. Bleeding disorders, autoimmune disease, blood cancers, low platelet counts, Von Willebrand disease, or medication side effects can lead to excessive bruising.

Bruising as a Sign of Elder Abuse

Unexplained frequent bruising may also be a red flag for physical elder abuse in the form of attacks, hits, slaps, kicks, or rough handling. Bruises may reflect the shape of an object or human hand.

Abusers often target areas covered by clothing like the torso, back, and upper thighs. Defensive bruises like grab marks on the arms are also common.

Caregivers and family should watch for unexplained bruises that seem inconsistent with an older person’s daily activities. Any suspicious bruising warrants medical evaluation and may need to be reported.

When to See a Doctor

Consult a physician promptly for:

• Unexplained bruising.
• Bruising that seems excessive for an injury.
• Bruises accompanied by bleeding.
• Multiple or recurring bruises.
• Very painful or swollen areas.
• Bruises slow to heal or lasting over two weeks.

A doctor can evaluate for underlying causes and check blood tests related to coagulation and platelets. They may adjust medications, recommend supplements or nutrition changes, or refer to a specialist as needed.

Proper treatment can reduce uncomfortable bruising and help seniors maintain healthy skin and mobility.
