Pressure ulcers, also known as bed sores, are damaged areas of skin or tissue caused by reduced blood flow, which can significantly affect the health and quality of life of patients with chronic diseases or limited mobility. Bed sores are complex and painful to treat, and if left untreated, can cause serious health complications. This article explores what bed sores are, the reasons for their occurrence, how they progress, and effective treatment and preventive strategies.
Bedsores are injuries to the skin or underlying tissue caused by prolonged pressure, particularly over bony areas such as the elbow tips, shoulders, heels, hips, or tailbone. These injuries are commonly seen in people who spend extended time in bed or in a wheelchair without frequently shifting their position.
Reduced blood flow to the skin and deeper tissues is the main cause of their formation. Continuous pressure limits circulation, preventing oxygen and nutrients from reaching the tissues. Over time, this causes cell death and leads to open wounds or ulcers. Bed sores are a nemesis for people with chronic conditions, which are associated with loss of sensation, prolonged immobility, age-associated skin fragility, and malnutrition.
The vulnerable population at the highest risk of developing bed sores includes the following:
Young people can also develop bed sores; however, older adults and those with chronic illnesses are affected more due to limited mobility.
The risk of bed sores is assessed using the Braden Scale, which evaluates six factors: sensory perception, mobility, moisture, nutrition, activity, and friction/shear. Except for friction/shear, which is rated on a scale of 1 to 3, the remaining five factors are assessed on a scale of 1 to 4. The lower the number, the higher the impairment.
Classification of bed sores is based on the degree of severity:
When intact skin is pressed, it results in a non-blanchable (does not turn white) persistent area of redness. This is an early warning sign of tissue damage.
Partial-thickness loss of skin, and the ulcer looks like an abrasion, blister, or shallow crater.
Full-thickness skin loss that involves subcutaneous fat, forming a deeper crater.
Widespread tissue damage down to muscle, bone, or tendons, increasing the risk of serious infections.
In some cases, a wound may be unstageable as dead tissue covers the damage, thereby requiring clinical intervention before a proper assessment.
Deep tissue pressure injury is another stage in which a dark red or purple-colored area on the skin does not disappear when pressed.
Initially, a bedsore might seem like a surface irritation, but it can cause serious health issues:
Infection: A broken skin barrier is an entry point for bacteria, leading to cellulitis or deeper infections.
Osteomyelitis: A very severe bone infection.
Sepsis: A life-threatening complication when the infection enters the bloodstream and requires urgent attention.
Delayed healing: Malnutrition, poor circulation, and chronic illnesses slow recovery.
Reduced quality of life: The pain, foul odor, frequent dressing changes, and limited mobility associated with bed sores can cause emotional distress.
For patients with chronic diseases, bed sores are not just a wound; they are an independent chronic condition that requires continued management and treatment.
Preventing the development of bed sores is far better than treating them once they develop. The strategies include the following:
Regular repositioning: The position of individuals who are bedridden should be changed every 1 to 2 hours to relieve pressure. Wheelchair users should shift their weight with the help of a caregiver every 15-30 minutes.
Skin care and hygiene: Using gentle cleansers minimizes skin irritation. Avoid cleansers with harsh chemicals that can cause dry skin. Apply barrier creams when needed.
Nutrition and hydration: Following a healthy diet rich in protein, vitamins (especially C and E), and zinc, and staying adequately hydrated promotes skin integrity and healing. Patients with limited oral intake may require nutritional supplements.
Pressure-relieving devices: Mattresses, cushions, and foam overlays that redistribute pressure and enhance blood flow can be used. High-risk patients are recommended to use alternating-pressure mattresses.
Attention to moisture: Sweating and incontinence increase the risk of skin breakdown. Thus, bedding and clothing must be changed regularly. The use of absorbent products aids in moisture reduction.
Education and assessment: Healthcare providers and caregivers should inspect the skin daily and assess risk using structured tools.
The general physician’s initial evaluation should include the duration of hospitalization or immobility; cause of immobility (e.g., trauma, stroke, etc.); ulcer site, duration, and size; history of diabetes, malignancy, or peripheral vascular disease; presence of foul odor or discharge; and patient awareness of ulcer pain.
If a bedsore is suspected, a prompt and thorough clinical assessment is crucial. The doctor examines the wound, determines the stage and depth, and evaluates the cause (e.g., diabetes), location, and size (using photographic evidence). The presence of pus or discharge can indicate a possible infection, so laboratory tests like blood culture are ordered to detect microorganisms. A nutritional assessment is also performed to identify any deficiencies, such as low hemoglobin, indicating anemia.
Pressure reduction: Once a bed sore develops, treatment focuses on reducing pressure on the affected area through repositioning, off-loading devices, and supportive surfaces.
Wound care: Use saline to gently clean the wound. Apply dressings to maintain a moist, protected environment. The choice of dressing depends on the amount of wound exudate and infection status. Foam silicone dressings are commonly recommended. Dead tissue may also need to be removed (debridement).
Pain and infection control: Abscesses may require drainage. Topical antiseptics, such as iodine or hydrogen peroxide, may be used for temporary infection control. Antibiotics are reserved for systemic infections. Pain can be controlled with appropriate analgesics.
Surgical options: Advanced ulcers (Stage III or IV) that fail to respond to conservative care may require surgical intervention. Surgical options include debridement, skin grafting (long-term durability is low; therefore, it is unsuitable for the late stages), and flap reconstruction (healthy and vascularized tissue, such as muscle or skin, is transferred to provide padding to bony areas or fill deep wounds).
Living With and Supporting Chronic Patients -H2
Caring for someone prone to bed sores can be medically and emotionally challenging. Family and professional caregivers should be trained to recognize the warning signs of bedsores, such as skin discoloration, foul odor, discharge, and loss of sensation. Chronic wounds can lead to feelings of helplessness. Emotional support and counseling can help patients cope with the feeling of helplessness associated with chronic wounds. Management of bed sores includes a multidisciplinary team of doctors, nurses, wound care specialists, dietitians, and physical therapists.
Bed sores are a preventable yet persistent challenge in chronic patient care. Prevention of bed sores requires consistency. Not repositioning for a few hours or neglecting skin care allows bed sores to develop. Understanding the causes, recognizing early signs, and implementing proactive care can reduce suffering, prevent complications, and improve quality of life.
For patients with chronic conditions, family members and caregivers must remain vigilant. By combining thoughtful and watchful caregiving with evidence-based prevention and treatment strategies, bed sores can be transformed from an inevitable consequence of immobility into a manageable, and often preventable, condition.
Early recognition and proactive care are essential to preventing and managing bed sores effectively.

Bed sores, also called pressure ulcers, are areas of damaged skin and tissue caused by prolonged pressure that reduces blood flow. They commonly develop in people who are bedridden, use wheelchairs, or have limited mobility.
The earliest sign is usually a persistent red, purple, or discoloured patch of skin that does not fade when pressed. The area may feel warm, painful, tender, itchy, or firmer than the surrounding skin.
People with limited mobility, older adults, individuals with diabetes, stroke, spinal cord injuries, poor nutrition, or reduced sensation are at higher risk. Long hospital stays can also increase the likelihood of developing bed sores.
Regular repositioning, good skin hygiene, proper nutrition, adequate hydration, and pressure-relieving mattresses or cushions can help prevent bed sores. Daily skin checks are especially important for high-risk patients.
Treatment depends on the severity of the ulcer and may include pressure relief, wound cleaning, specialised dressings, infection control, nutritional support, and, in advanced cases, surgery. Early treatment improves healing outcomes and reduces complications.
Seek medical attention if you notice persistent skin redness, swelling, foul-smelling discharge, increasing pain, fever, or an open wound. Early assessment can prevent the ulcer from progressing to deeper tissue damage or infection.
Management often involves a multidisciplinary team that may include general physicians, wound care specialists, surgeons, physiotherapists, nurses, and dietitians. This coordinated approach helps improve healing and prevent recurrence.
