Being bedridden means being confined to bed, unable to get up or walk without help, because of illness, injury, surgery or frailty. Lying still for long periods affects almost every part of the body: in a study of 20,515 bedridden hospital patients, 12.7% developed at least one major complication of immobility, most often pneumonia, pressure injuries, blood clots or urinary tract infections. Down-Under Wool has supplied families caring for a bed-confined person since 1988, and this guide explains the main complications of being bedridden, why they happen, and the everyday steps caregivers can take to lower the risk.
What does bedridden mean?
Bedridden means a person spends all or most of the day in bed and cannot get up without help. "Bed confined", "bedbound" and "bedridden" are used for much the same thing, and a 2025 scoping review of research on bedriddenness found there is still no agreed definition. One formal definition comes from Medicare: under 42 CFR 410.40, a person is "bed confined" only if they are unable to get up from bed without assistance, unable to walk, and unable to sit in a chair or wheelchair.
What causes someone to become bedridden?
People usually become bedridden after a serious illness, an injury or an operation, or gradually as a long-term illness or frailty progresses. A hospital stay is a common turning point: about one in three patients over 70 leave hospital less able to manage everyday activities than before, even when the illness that brought them in was treated successfully. The same scoping review notes that bedriddenness mainly affects older people, particularly in nursing homes, and that mobility usually declines step by step, so keeping someone moving, as far as their doctor allows, matters from the first day.
What are the complications of being bedridden?
The main complications of being bedridden are pressure injuries, muscle and bone loss, stiff joints, blood clots, chest infections, urinary tract infections, constipation and low mood. In the study of 20,515 bedridden patients in Chinese hospitals, pneumonia affected 8.2%, pressure ulcers 2.6%, deep vein thrombosis 1.7% and urinary tract infections 1.3% during their stay, and patients with any of these reported a lower quality of life after discharge.
| Complication | Why bed rest causes it | What caregivers can do |
|---|---|---|
| Pressure injuries (bed sores) | constant pressure on bony areas reduces blood flow to the skin | change position every 1 to 2 hours; check the skin daily; use a pressure-reducing surface |
| Muscle loss and weakness | muscles that aren't used shrink, starting within the first week | keep up any exercises and movement the care team recommends |
| Stiff joints (contractures) | joints held still tighten and lose their range | ask a physical therapist for daily range-of-motion exercises |
| Bone loss | bones that don't bear weight lose density | sit up, stand or bear weight when allowed |
| Blood clots (deep vein thrombosis) | being confined to bed for 3 days or more raises the risk | fluids, leg movement, and any stockings or medicine the doctor prescribes |
| Pneumonia (chest infection) | the longer someone stays in bed, the higher the odds of a lung infection | ask about breathing exercises; report a cough, fever or breathlessness |
| Urinary tract infection | seen in 1.3% of bedridden hospital patients in the study above | keep skin clean and dry; report a new fever or change in urine to the doctor |
| Constipation | lying down for long periods slows the bowel | fluids, fiber, a regular toilet routine |
| Low mood and poor sleep | illness, pain, boredom and loneliness | company, a daily routine, and telling the doctor about low mood |
Muscle, bone and joint changes
Muscle and bone start to change quickly. A review of bed rest research describes rapid reductions in muscle mass and bone mineral density within the first week of bed rest, made worse by critical illness. In healthy volunteers with an average age of 67, just 10 days of bed rest reduced knee strength by about 13%, stair-climbing power by 14% and aerobic capacity by 12%. A review in Critical Care Medicine adds joint contractures and blood clots to the complications that can delay recovery.
Blood clots
Being confined to bed for 3 days or more raises the risk of deep vein thrombosis (DVT), a blood clot in a vein, usually in the leg, according to the NHS. Hospital teams assess this risk and may prescribe medicine or compression stockings, sometimes continued at home.
Chest infections
Lung infections are the most common of these complications. A meta-analysis of 13 studies (10,182 long-term bedridden patients) found that a longer time in bed raised the odds of a lung infection (odds ratio 2.69), with tube feeding and ventilator use carrying even higher risk.
Constipation and low mood
The NHS lists not moving enough and spending long periods sitting or lying down among the causes of constipation, along with some medicines, too little fluid and too little fiber. Low mood is common too: the NHS says a longstanding or life-threatening illness and feeling lonely or cut off from family and friends both raise the risk of depression.
How do you prevent bed sores in a bedridden person?
You prevent bed sores in a bedridden person by moving their weight off bony areas often, checking their skin every day and giving them a pressure-reducing surface to lie on. MedlinePlus advises changing position every 1 to 2 hours in bed, keeping sheets dry and free of wrinkles, lifting the person or using a draw sheet rather than dragging them, and putting a pillow under the calves so the heels lift clear. Our guide to care of pressure points shows which areas to protect in each position, and the full prevention plan is on our bedsore prevention page.
Medical sheepskin is one of the few bed surfaces with trial evidence. A Cochrane review of three trials found Australian standard medical sheepskins reduce pressure ulcers, and in the largest trial (441 patients) 9.6% of patients on a sheepskin developed one, against 16.6% with usual care. Use it with the skin directly on the wool, and keep turning on schedule; placement tips are in how to use sheepskin for bed sores. If the person already has a sore, ask their nurse or doctor how to care for it.
How can caregivers help prevent the other complications?
Caregivers help most by keeping the person moving as much as their doctor allows, and by looking after fluids, food, skin and company.
- Keep them moving. Sitting up, standing for a moment or moving arms and legs in bed all count. Ask a physical therapist for a daily exercise and stretching routine. Time in a chair helps too; a medical sheepskin for a recliner chair or a wool seat cushion protects the skin while they sit.
- Help them breathe deeply. Ask the nurse or therapist about breathing and coughing exercises, and report a new cough, fever or breathlessness quickly.
- Offer drinks often. The NHS notes DVT is more likely if you're dehydrated, and fluids also help prevent constipation.
- Add fiber gradually and keep a regular, unhurried toilet routine.
- Keep skin clean and dry. Clean right away after any accident with urine or stool and dry well. Washable incontinence bedding makes changes quicker.
- Feed them well. MedlinePlus advises enough calories and protein and plenty of water to protect the skin.
- Keep them company. Visitors, phone calls and familiar routines ease loneliness, which the NHS links to depression.
When should you get medical help?
Get medical help urgently if a bedridden person develops throbbing pain or swelling in one leg, which can be a DVT, and call emergency services if they are short of breath or have chest pain, which can mean a clot has reached the lungs (NHS). Contact their doctor or nurse about redness or any skin change over a bony area that lasts more than a few days, a sore that has pus or is getting more painful, a high temperature, or constipation that is not getting better.
What bedding helps a bedridden person?
The best bedding for a bedridden person is soft, breathable and washable, with a pressure-reducing layer over the mattress. Caregivers most often choose:
- A medical sheepskin or wool overlay under the shoulders, back and hips: the Australian Medical Sheepskin (AS4480.1), about 38 x 24-26 inches, or the 30 x 60 inch Superior Overlay XD, which is machine washable and urine resistant. See all medical sheepskin, or compare surfaces in our guide to the best mattress topper for bed sores.
- A full-mattress wool cover for a hospital bed: the Hospital Bed Nursing Fleece is 35 x 80 inches with an elasticized skirt.
- A urine-resistant pad for someone who is incontinent: the 30 x 60 inch Hospital Wool Fleece Bed Pad can be machine washed and dried.
- Heel and foot protection: the Pressure Care Assistant wool strip at the foot of the bed, a sheepskin heel pad, or our boots and booties for pressure sores; our guide to heel protectors for bed sores compares them.
Our bedsore prevention packages combine a sheepskin with foot protection and Woolskin wash, and all our bed sore prevention products are in one place. For someone coming home from hospital, read hospital to home care with medical sheepskin.
Bedridden FAQs
What is the difference between bedbound and bedridden?
There is no practical difference: both words describe someone who cannot get out of bed without help. Researchers have noted there is no agreed definition of either term, so care teams describe what the person can and can't do instead.
What does bed confined mean for Medicare?
For Medicare ambulance rules, bed confined means the person cannot get up from bed without help, cannot walk, and cannot sit in a chair or wheelchair. All three must apply.
Is bedridden a medical diagnosis?
No. Bedridden describes a person's mobility, not a disease; the cause is the diagnosis. Medical records can still note it with the ICD-10 code Z74.01, bed confinement status.
What illnesses are common in bedridden patients?
Pneumonia, pressure injuries, blood clots and urinary tract infections are the major complications studied in hospital patients. Constipation, muscle weakness, stiff joints and low mood are also common.
How often should a bedridden person be turned?
Every 1 to 2 hours in bed, according to MedlinePlus, unless the care team sets a different schedule.
How quickly do bedridden people lose muscle?
Quickly: research reviews describe measurable loss of muscle mass within the first week of bed rest, and healthy older volunteers lost about 13% of their knee strength in 10 days.
How long can a bedridden person live?
It depends on why they are bedridden and on their overall health, so only their own doctor can answer. Preventing pneumonia, clots and pressure injuries protects their comfort whatever the outlook.
The short version
Being bedridden affects the skin, muscles, bones, blood, lungs, bowel and mood, and the changes start within days. Caregivers make the biggest difference by changing position every 1 to 2 hours, keeping the person moving, offering fluids and fiber, keeping skin dry, and providing a pressure-reducing surface such as a medical sheepskin.
