Pressure injuries, also known as pressure ulcers, sores or bedsores, are caused by prolonged pressure on the skin, which reduces blood flow and causes the skin to die. They most commonly occur on the buttocks, elbows, hips, heels, ankles, shoulders, back and the back of the head. Nutritional deprivation and insufficient dietary intake are key risk factors for the development of pressure injuries and impaired wound healing. Therefore, maintaining a healthy weight and eating a balanced diet with adequate nutrients can help to prevent and treat pressure injuries.
| Characteristics | Values |
|---|---|
| Body Weight | Maintaining a healthy weight can reduce the risk of developing pressure injuries and support wound healing. Being underweight can mean there is less natural padding on bony areas, while being overweight can reduce mobility and increase weight on pressure areas. |
| Diet | Eating a balanced and varied diet with adequate nutrients, vitamins, and minerals can help prevent and treat pressure injuries by supporting wound healing. |
| Nutritional Status | Proper nutrition keeps the skin healthy and aids in repair. Consuming sufficient protein, zinc, and vitamin C is especially important for pressure ulcer healing. |
| Weight Loss | Unplanned weight loss is a risk factor for pressure ulcer development as it can indicate malnutrition and impair wound healing. |
| Supplements | Vitamin and mineral supplements can be beneficial for those with poor food intake or unable to maintain a varied diet. Oral nutritional supplements may be recommended by a dietitian for those unable to meet their nutritional needs through diet alone. |

What You'll Learn
Maintaining a healthy weight
Eat a Balanced Diet
A balanced diet is crucial for maintaining a healthy weight and reducing the risk of pressure injuries. Ensure you eat a variety of healthy foods, including fruits, vegetables, whole grains, low-fat dairy, and lean proteins. If you are living with overweight and have a pressure injury, it is important to continue eating a balanced diet to provide your body with the nutrients it needs for healing.
Manage Your Calorie Intake
To maintain a healthy weight, it is important to manage your calorie intake. If you need to lose weight, eat fewer calories than recommended for your activity level. Conversely, if you need to gain weight, increase your calorie intake while maintaining a moderate activity level. Limiting portion sizes can help control your calorie intake.
Stay Active
Physical activity is essential for maintaining a healthy weight and reducing the risk of pressure injuries. Aim to be as physically active as possible. Walking is a great way to add more physical activity to your lifestyle. Regular moderate or vigorous exercise provides immediate and long-term health benefits and can help you maintain a healthy weight as you age.
Get Enough Sleep and Manage Stress
Optimal sleep and stress reduction are important factors in maintaining a healthy weight. Make sure you are getting sufficient sleep and finding healthy ways to manage stress.
Consult a Healthcare Professional
Before starting any weight loss or gain journey, it is important to consult your doctor or a healthcare professional. They can provide guidance and advice tailored to your specific needs and help you make healthy changes in a safe and sustainable way.

Eating a balanced diet
Maintaining a healthy weight through a balanced diet is crucial in reducing the risk of pressure injuries. Being underweight increases the risk due to reduced natural padding in bony areas like the hips and bottom. On the other hand, being overweight can reduce mobility and increase pressure on these areas. Therefore, a balanced diet that provides adequate nutrition is vital to maintaining a healthy weight and reducing the likelihood of developing pressure injuries.
A balanced diet ensures the body receives all the necessary nutrients for wound healing. Nutrient-rich foods, including proteins, vitamins, minerals, and zinc, are particularly important. For instance, protein is crucial in maintaining a positive nitrogen balance and promoting wound healing through collagen synthesis and immune function. Additionally, vitamin C and zinc are known to support skin health and aid in the healing process.
To enhance the nutritional content of meals, nutrient-rich ingredients can be added. For example, skimmed milk powder, cheese, eggs, or nut spread can be incorporated into various dishes. Consuming a full and varied diet ensures the body receives a diverse range of nutrients, reducing the need for additional vitamin and mineral supplements to aid wound healing. However, in cases of poor food intake or an inability to maintain a varied diet, vitamin and mineral supplements can be beneficial.
Overall, eating a balanced diet supports a healthy weight and provides the body with the necessary tools for wound healing, thereby reducing the risk of developing pressure injuries and promoting recovery.

Consuming adequate protein
Protein-calorie malnutrition, for instance, results in a decrease in lean body mass or protein stores, which negatively affects the healing process. To prevent this, it is important to ensure that individuals at risk of developing pressure injuries receive sufficient protein.
However, it is also crucial to consider other nutritional factors, such as energy intake, to ensure that the additional protein can be used effectively for tissue healing. The body's total energy needs must be met, as decreased energy intake results in a decreased nitrogen balance, which is essential for maintaining cell membrane integrity.
Therefore, consuming adequate amounts of carbohydrates and fats is important to prevent the body from using protein as an energy source. Monounsaturated and polyunsaturated fats provide energy for wound healing and help maintain cell membrane integrity.
To summarise, consuming adequate protein is crucial for preventing and treating pressure injuries, but it should be accompanied by a balanced diet that includes sufficient energy, carbohydrates, fats, vitamins, and minerals to optimise the body's healing process.

Importance of vitamins and minerals
A healthy diet and a balanced body weight are key factors in reducing the risk of developing pressure injuries and supporting wound healing. Eating a varied, balanced diet can ensure the body has all the nutrients it needs to enable wound healing. Maintaining a healthy weight can also reduce the risk of developing pressure injuries by reducing the weight on pressure areas of the body, such as the hips and bottom.
Being underweight can increase the risk of developing pressure injuries as there is less natural padding on bony areas. If you have lost weight unintentionally, you may have lost some of your body's nutrient stores, and healing may take longer.
If you are overweight, this can reduce your mobility and increase the weight on pressure areas. However, it is important not to try to lose weight during this time, as this can negatively impact your health. Instead, focus on eating a balanced diet with regular, nutritious meals.
Malnutrition is a significant factor influencing pressure injury risk and wound healing. Micronutrients should be replaced if depleted, but routine supplementation of vitamins and minerals in all pressure ulcer patients is not recommended. However, if dietary intake is poor or deficiencies are confirmed or suspected, vitamin and mineral supplements can be beneficial.
Consuming adequate protein, zinc, and vitamin C can help pressure ulcers heal. Vitamin C may impact collagen formation, immunomodulation, and antioxidant functions, although more research is needed.

Healing and nutrition
Pressure injuries, also known as pressure ulcers, sores or bedsores, are caused by prolonged pressure on the skin, which reduces blood flow and causes the skin to die. These injuries most commonly occur on the buttocks, elbows, hips, heels, ankles, shoulders, back and the back of the head.
Nutrition and weight play a significant role in both the prevention and treatment of pressure injuries. Being underweight increases the risk of developing pressure injuries as there is less natural padding on bony areas. Similarly, being overweight increases the risk as it can reduce mobility and increase pressure on areas like the bottom. In both cases, maintaining a healthy weight and eating a balanced diet can reduce the risk of developing pressure injuries.
Once a pressure injury has developed, nutrition and hydration are vital to the wound healing process. At every stage of healing, the body requires a balance of nutrients. Consuming adequate protein, zinc and vitamin C can aid in healing pressure ulcers. The NPUAP/EPUAP recommends a protein intake of 1.25 to 1.5 g/kg of body weight per day for pressure ulcer healing. For patients with Stage III/IV pressure ulcers, the proposed level is 1.5–2.0 g/kg, depending on the size of the ulcer and the total protein loss from draining wounds.
To increase nutrient intake, nutrient-rich ingredients can be added to meals. For instance, skimmed milk powder, cheese, eggs or nut spread can be included in dishes. It is also important to maintain a balanced diet when injured. This can be achieved by choosing low-fat cooking methods such as grilling, baking, microwaving or steaming, and selecting snacks that are high in protein but low in energy, like yoghurt or boiled eggs. If an individual is unable to eat enough food to meet their body's needs, a dietitian may advise taking an oral nutritional supplement.
