Bedsores in seniors — known medically as pressure ulcers or pressure injuries — are one of the most common, most painful, and most preventable complications of limited mobility. They can develop in as little as two to three hours of unrelieved pressure, and roughly 3 million American adults are affected every year. The encouraging news: with the right repositioning schedule, skin care, nutrition, and support surfaces, the large majority are avoidable. This guide explains the stages, the warning signs, and the proven prevention steps every senior and caregiver should know.

What Are Bedsores and Where They Form
A pressure ulcer is localized damage to the skin and the tissue beneath it, caused when sustained pressure cuts off blood flow. Without oxygen and nutrients, skin cells begin to die. Because older skin is thinner, drier, and less elastic, seniors are especially vulnerable — and the damage can start under intact skin before anything is visible on the surface.
Bedsores form over bony areas where there is little cushioning fat. The most common sites are the tailbone (sacrum), heels, hips, shoulder blades, elbows, the back of the head, and the ears. For someone who sits most of the day, the tailbone and buttocks are the highest-risk zones; for someone confined to bed, heels and the sacrum lead the list.
The 4 Stages of Pressure Ulcers
Clinicians classify pressure injuries by depth. Catching them at Stage 1 is critical, because early sores heal with basic care while advanced ones may require surgery.
| Stage | What You See | Outlook |
|---|---|---|
| Stage 1 | Intact skin with a reddened area that does not turn white when pressed; may feel warm, firm, or painful | Reversible with pressure relief |
| Stage 2 | Partial-thickness loss — a shallow open sore or blister | Heals with proper wound care |
| Stage 3 | Full-thickness loss exposing fat; a deeper crater | Weeks to months; needs clinical care |
| Stage 4 | Deep wound exposing muscle, tendon, or bone | Serious; may need surgery/grafts |
Two additional categories exist: unstageable (the base is covered by dead tissue) and deep tissue injury (a purple or maroon area of intact skin signaling damage underneath). Both require prompt professional evaluation.
Who Is Most at Risk (The Braden Scale)
Nurses assess risk using the Braden Scale, which scores six factors — sensory perception, moisture, activity, mobility, nutrition, and friction/shear. Scores range from 6 to 23, and lower means higher risk. A score of 18 or below flags a senior as at-risk, triggering a formal prevention plan.
Beyond immobility, the biggest contributors are incontinence and moisture (which macerate skin), poor nutrition and low protein, dehydration, diabetes and poor circulation, reduced sensation, and friction from sliding down in a bed or chair. Anyone recovering from surgery, a stroke, or a hip fracture — or receiving home health care — deserves close skin monitoring.
7 Proven Prevention Steps
1. Reposition on a Schedule
The single most effective step. Shift position at least every 2 hours in bed and every 15 minutes in a chair (or every hour if the person can help with a small “pressure-relief lift”). Set a timer so turns are never skipped.
2. Use Pressure-Redistributing Surfaces
Foam or gel cushions, alternating-pressure mattresses, and heel-protector boots spread weight away from bony points. Never use a ring or “donut” cushion — it concentrates pressure around the rim and can cause new sores.
3. Keep Skin Clean and Dry
Cleanse promptly after incontinence, pat (don’t rub) dry, and apply a barrier cream. Manage moisture with breathable, wicking products.
4. Inspect the Skin Daily
Check every high-risk area once a day in good light. Press any red spot: if it does not blanch (turn white), treat it as a Stage 1 sore and relieve all pressure immediately.
5. Reduce Friction and Shear
Use a draw sheet to lift rather than drag, keep the head of the bed at 30 degrees or less when possible, and prevent sliding down in the chair.
6. Keep Moving
Even small, frequent movements help. Gentle range-of-motion activity and, where possible, seated movement improve circulation and reduce continuous pressure.
7. Optimize Nutrition and Hydration
Well-nourished skin resists breakdown and heals faster (covered in detail below).
The Nutrition Connection
Skin is living tissue that needs building blocks to stay intact and to heal. Protein is the most important: seniors at risk generally need 1.0–1.5 grams of protein per kilogram of body weight daily, well above the old 0.8 g/kg standard. Adequate calories, vitamin C, zinc, and fluids also matter. A senior who is losing weight or eating poorly should be evaluated by a clinician or dietitian, because malnutrition is one of the strongest predictors of a sore that will not heal. Our guide to protein needs for seniors breaks down easy ways to hit those targets.
When to Call the Doctor
Contact a healthcare provider promptly if a sore breaks the skin, grows, drains fluid, or smells foul, or if the surrounding skin becomes hot, swollen, or increasingly painful. Fever or confusion can signal a spreading infection (cellulitis or, rarely, sepsis) and warrants urgent care. Medicare covers physician wound care, skilled nursing wound care at home for qualifying homebound patients, and many pressure-relieving support surfaces as durable medical equipment — ask your provider what applies to your situation.
Frequently Asked Questions
How fast can a bedsore develop?
Damage can begin in as little as 2 to 3 hours of unrelieved pressure, and sometimes faster in frail or poorly nourished seniors. That is why the 2-hour repositioning rule exists — the clock resets each time position changes.
Can bedsores heal at home?
Stage 1 and many Stage 2 sores heal at home with consistent pressure relief, clean dressings, and good nutrition. Stage 3 and 4 wounds need professional wound care and should never be managed alone.
What is the first sign of a bedsore?
A patch of skin — often over a bony area — that is reddened, warm, firm, or tender and does not turn white when you press it. On darker skin tones the change may look purple, blue, or shiny rather than red. Relieve pressure from that spot immediately.
Does Medicare cover pressure ulcer treatment?
Yes. Medicare Part B covers medically necessary wound care and many support surfaces as durable medical equipment, and Part A covers wound care during a covered hospital or skilled nursing stay. Home-health wound care is covered for qualifying homebound patients.
