All About Bed Sores: Causes, Prevention, and Healing

October 17, 2025

Bed sores, also known as pressure ulcers or pressure injuries, are a painful and common condition that occurs when skin and the underlying tissue are damaged due to prolonged pressure. They often develop when a person stays in one position for too long, preventing proper blood flow to certain areas of the body. Over time, the lack of circulation causes the skin to break down, leading to redness, irritation, and eventually open wounds.These sores most commonly appear on bony parts of the body such as the heels, hips, tailbone, and elbows, where pressure is highest. People who spend long periods in bed or in a wheelchair are especially vulnerable, particularly if they have limited mobility, weakened muscles, or health conditions that affect sensation or healing. Without proper prevention and care, bed sores can become infected and lead to serious complications that impact overall health and quality of life.

What Causes Bed Sores?

Bed sores develop when there is continuous pressure on a specific part of the body, which cuts off blood flow to the skin and underlying tissue. When circulation is restricted for too long, cells are deprived of oxygen and essential nutrients, causing the affected area to weaken and eventually break down. This process can begin within just a few hours of unrelieved pressure, especially in individuals who have limited mobility or are confined to a bed or wheelchair.

Common areas where bed sores form include the tailbone, heels, hips, shoulders, and elbows, as these are points where bones are close to the surface of the skin and receive the most pressure. The risk is even higher if the person lies or sits in the same position for extended periods without shifting their weight.

In addition to pressure, friction and shear forces play a significant role in worsening the condition. Friction occurs when the skin rubs against bedding or clothing, while shear happens when the skin moves in one direction and the bone beneath it moves in another, such as when sliding down in a bed or chair. Moisture from sweat, urine, or wounds can further weaken the skin’s protective barrier, making it more prone to tears and infection. Even small or repeated movements without adequate support can cause irritation, which may progress into painful sores if not addressed early.

Who Is Most at Risk?

Anyone with limited mobility can develop bed sores, especially if they are unable to change positions regularly or require assistance to move. Certain groups of people face a higher risk due to medical, age-related, or environmental factors. These include:

People who are bedridden or use wheelchairs: Individuals who spend most of their time lying down or sitting experience constant pressure on specific areas of the body. Without frequent repositioning or pressure relief, the skin and tissue can begin to deteriorate.
Older adults with fragile or thinner skin: As we age, the skin naturally loses elasticity, collagen, and moisture, making it more prone to damage. Older adults may also have reduced muscle mass and circulation, which slows healing and increases the likelihood of developing sores.
Patients recovering from surgery or severe illness: After surgery or during recovery from illness, people may be required to stay in bed for extended periods. Limited mobility, combined with the body’s focus on healing other areas, can make the skin more vulnerable to pressure-related injuries.
Those with spinal cord injuries or neurological conditions: Conditions that affect nerve function, such as spinal cord injuries, multiple sclerosis, or paralysis, reduce the ability to feel pain or discomfort. Because these individuals may not notice early warning signs like tingling or redness, sores can form and progress quickly without being detected.

Other contributing factors include poor nutrition, dehydration, incontinence, and certain chronic diseases like diabetes, which can slow down the healing process and weaken skin integrity. Understanding who is most at risk is the first step in preventing bed sores before they start.

Early Signs of Bed Sores

Identifying bed sores early can prevent serious complications and make treatment much easier. Catching the first signs allows caregivers and patients to take action before the sores progress into deeper wounds. Bed sores typically develop in stages, starting with subtle skin changes and, if left untreated, advancing to severe tissue damage.

Common early signs include:

Red or discolored patches that do not fade after pressure is relieved: This is often the first indication that a sore is developing. In people with lighter skin tones, the area may appear red, while in darker skin tones, it can look purple, blue, or shiny. The skin may also feel unusually firm or soft to the touch.
Warm, tender, or swollen skin: Increased warmth or tenderness in one area can signal inflammation or poor circulation. If the skin feels different compared to surrounding areas, it’s important to reduce pressure immediately.
Blisters or open wounds in more advanced stages: If pressure continues, the skin can begin to blister or tear, creating shallow open sores. In severe cases, the ulcer can deepen into the muscle or bone, leading to infections that may require medical or surgical treatment.

Other symptoms to watch for include pain, unusual odor, drainage, or discoloration around the wound edges. Regularly checking the skin, especially over bony areas like the tailbone, heels, and hips, can help detect changes early. For people with limited sensation or mobility, caregivers should perform daily skin inspections as part of a consistent care routine.

Recognizing these warning signs early and relieving pressure right away can prevent small irritations from becoming serious wounds that are painful and difficult to heal.

How to Prevent Bed Sores

Preventing bed sores involves relieving pressure, improving blood flow, and keeping the skin healthy. The key is to be proactive rather than reactive, since early prevention is much easier than treating advanced wounds. Consistent daily care routines and the right supportive equipment can make a huge difference in protecting the skin and promoting comfort.

Here are some effective methods to prevent bed sores:

Reposition regularly: Shifting positions every 1–2 hours helps reduce constant pressure on one area. For people who are bedridden, caregivers can gently turn them from side to side or adjust the bed’s angle to relieve pressure on the tailbone and hips. For wheelchair users, leaning forward or side-to-side for a few minutes several times a day can also improve circulation.
Use pressure-relieving surfaces: Specialized products like air mattresses, gel cushions, and adjustable beds help distribute weight evenly and minimize the buildup of pressure points. These surfaces adapt to the body’s shape, reducing friction and shear that often lead to skin damage. Investing in high-quality support surfaces can significantly lower the risk of developing sores, especially for long-term care patients.
Maintain skin hygiene: Keeping the skin clean, dry, and moisturized helps preserve its natural protective barrier. Gently cleanse the skin with mild soap and water, then pat dry instead of rubbing. For those prone to sweating or incontinence, using moisture-wicking pads or protective creams can reduce irritation and bacterial growth.
Stay nourished and hydrated: Proper nutrition plays a major role in skin health and healing. Diets rich in protein, vitamins A and C, zinc, and antioxidants help the body repair tissue and maintain elasticity. Staying hydrated keeps the skin supple and less prone to cracking. For individuals who have trouble eating or drinking enough, caregivers may need to monitor fluid and nutrient intake closely.
Encourage gentle movement and exercise: Even small leg lifts, arm stretches, or range-of-motion exercises can boost circulation and strengthen muscles. For bedridden individuals, assisted movement helps keep blood flowing and reduces the risk of stiffness and pressure injuries.
Inspect the skin daily: Early detection is key. Regularly check high-risk areas such as the heels, hips, shoulders, and lower back for redness, discoloration, or swelling. Addressing these signs right away can prevent sores from forming or worsening.

By following these preventive measures, caregivers and patients can work together to reduce discomfort, promote independence, and improve overall quality of life.

Healing and Recovery

If bed sores do appear, treatment focuses on cleaning the wound, relieving pressure, and promoting skin repair. The goal is to stop further tissue damage, prevent infection, and create the right environment for healing. The treatment plan depends on how advanced the sore is, as pressure injuries range from mild redness to deep wounds that expose muscle or bone.

In the early stages, treatment usually involves gently cleaning the area, keeping the wound dry, and using specialized dressings or barrier creams that protect the skin from moisture and bacteria. Repositioning is also essential, as reducing pressure allows blood to flow back to the affected area and speeds up recovery.

For more advanced sores, medical professionals may prescribe antibiotics to treat or prevent infection. In some cases, a wound care specialist may use techniques such as debridement, which removes dead or infected tissue so healthy skin can grow. Severe ulcers that extend into deeper layers of tissue might require surgical repair or skin grafts to close the wound and restore function.

Alongside medical treatment, nutrition and hydration play an important role in recovery. A diet high in protein, vitamins, and minerals helps rebuild damaged skin and strengthen the immune system. Physical therapy may also be recommended to improve circulation, mobility, and flexibility, especially for patients who spend long hours in bed or a wheelchair.

It is important to monitor bed sores closely throughout the healing process. Changes in color, swelling, odor, or pain can be signs of infection or delayed healing and should be evaluated by a healthcare provider right away. The sooner bed sores are identified and treated, the faster the healing process begins, reducing discomfort and the risk of complications.
