The terms bed sores and pressure ulcers are often used interchangeably, creating confusion for older adults and their families. While they refer to the same underlying type of skin injury, the terminology reflects different levels of medical precision.
Understanding the distinction and the similarities helps clarify risks, recognize early signs, and appreciate why these wounds require careful attention, particularly in older adults.
Two Terms, One Condition

At their core, bed sores and pressure ulcers describe damage to the skin and underlying tissue caused by prolonged pressure.
The term bed sores is informal and commonly used in everyday language. It suggests wounds associated with long periods spent in bed. Pressure ulcers is the medical term used by healthcare professionals and reflects a broader understanding of how these injuries develop.
The condition is the same; the language differs.
Why “Pressure Ulcer” Is the Preferred Term
Pressure ulcers can occur anywhere prolonged pressure restricts blood flow not only in bed.
They may develop on heels, hips, lower back, elbows, or shoulders, whether a person is lying down or sitting for extended periods. The medical term emphasizes the cause pressure rather than the setting. Using precise terminology helps ensure accurate assessment and appropriate care.
How These Wounds Develop
Pressure reduces blood flow to the skin and underlying tissues. Without adequate oxygen and nutrients, cells become damaged and eventually die.
In older adults, thinner skin, reduced circulation, and slower healing accelerate this process. What begins as mild redness can progress to deeper tissue injury if pressure is not relieved.
Time and immobility are key factors.
Early Signs Are Often Overlooked
Early-stage pressure-related injuries may be subtle.
The skin may appear red, warm, or slightly discolored and may not blanch when pressed. Because discomfort may be mild or absent, early warning signs are often missed.
Recognizing early changes is critical to preventing progression.
Why Older Adults Are at Higher Risk
Aging skin is less resilient and recovers more slowly from stress.
Reduced fat padding, weaker skin structure, and diminished sensation increase vulnerability. Even short periods of pressure can cause damage when the skin’s tolerance is reduced.
Risk increases with limited mobility, but vulnerability exists even without complete immobility.
Why Terminology Matters for Prevention
Understanding that bed sores and pressure ulcers are the same condition reinforces the importance of prevention beyond the bed.
Pressure relief, skin monitoring, and position changes matter in all daily situations. Accurate language helps shift focus from location to cause pressure itself. Prevention begins with awareness.
Bed Sores vs Pressure Ulcers: Key Differences Explained
| Term | Meaning | Why It’s Used |
|---|---|---|
| Bed sores | Informal term | Common language |
| Pressure ulcers | Medical term | Clinical accuracy |
| Cause | Prolonged pressure | Reduced blood flow |
| Common locations | Bony areas | High-pressure zones |
| Risk in older adults | Higher vulnerability | Fragile skin |
One Condition, Many Misunderstandings
Bed sores and pressure ulcers are not separate conditions, they are two names for the same type of injury. The difference lies in how the condition is described, not in how it develops.
Clear understanding of terminology supports earlier recognition, better prevention, and more effective care for aging skin.
FAQ – Bed Sores and Pressure Ulcers
Are bed sores and pressure ulcers the same thing?
Yes. They refer to the same pressure-related skin injury.
Why do professionals say “pressure ulcers”?
It accurately describes the cause rather than the setting.
Can pressure ulcers occur without being in bed?
Yes. They can develop from prolonged sitting or pressure in any position.
Are early pressure ulcers painful?
Not always. Early signs may be painless and easy to miss.
Why are older adults more at risk?
Thinner skin, reduced circulation, and slower healing increase vulnerability.
