How do I reduce the risk of ulcers or infections? 

To reduce the risk of ulcers or infections, you must maintain healthy circulation and protect the integrity of your skin, particularly on the lower limbs. Key strategies include daily foot inspections, wearing well-fitting footwear, keeping skin hydrated with emollients, and managing underlying conditions like diabetes or Peripheral Arterial Disease (PAD). Early detection of minor breaks in the skin is essential to prevent them from progressing into chronic ulcers or deep-seated infections. 

Ulcers and skin infections, especially on the legs and feet, are often the result of compromised circulation or nerve damage. When the body cannot deliver enough oxygenated blood to the tissues or efficiently clear waste products, the skin becomes fragile and slow to heal. For individuals with long-term health conditions, a small scratch can quickly escalate into a significant medical concern. 

Prevention is far more effective than treating an established ulcer. By adopting a proactive self-care routine and understanding the factors that put your skin at risk, you can maintain your mobility and avoid the need for intensive clinical interventions. This article explores the daily habits and lifestyle changes that offer the best protection against skin breakdown.

Understanding why ulcers form 

Ulcers typically form when there is a failure in the circulatory system. Venous ulcers occur when blood pools in the legs due to faulty valves, leading to increased pressure and skin breakdown. Arterial ulcers occur when narrowed arteries cannot deliver enough blood to the feet, causing the tissue to die. 

In both cases, the skin loses its natural resilience. In patients with diabetes, nerve damage (neuropathy) may also be present, meaning they might not feel a stone in their shoe or a blister forming until it has already become infected. 

• Venous Ulcers: Usually found above the ankle; often accompanied by swelling and skin staining. 

• Arterial Ulcers: Usually found on the toes or heels; often very painful and look ‘punched out’. 

• Diabetic Ulcers: Frequently located on pressure points on the sole of the foot. 

Daily skincare and inspection 

The most effective way to prevent an ulcer is to catch skin changes before they open. You should perform a daily inspection of your legs and feet, ideally in a well-lit room. If you have limited mobility, use a mirror to see the soles of your feet or ask a family member to help. 

Hydration is equally important. Dry skin is prone to cracking, which creates an entry point for bacteria. Use a fragrance-free emollient daily, but avoid applying it between the toes, as excessive moisture in these gaps can lead to fungal infections. 

Step	Action	Benefit
Inspection	Look for redness, blisters, or swelling	Early detection of pressure points
Cleaning	Wash feet daily in lukewarm water	Reduces bacterial load on the skin
Drying	Pat skin dry, especially between toes	Prevents fungal growth (athlete’s foot)
Moisturising	Apply cream to heels and dry patches	Maintains skin elasticity and prevents cracks

Footwear and protective measures 

Your choice of footwear is a critical factor in ulcer prevention. Shoes that are too tight can cause friction blisters, while shoes that are too loose allow the foot to slide, creating shear forces that damage the skin. 

Always check the inside of your shoes for stones, grit, or torn linings before putting them on. If you have been prescribed compression hosiery for venous issues, ensure you wear it exactly as directed, as this supports your circulation and prevents the fluid buildup that leads to venous ulcers. 

• Avoid Walking Barefoot: Even indoors, wear slippers or shoes to protect against stubs or sharp objects. 

• Cotton Socks: Choose socks with non-binding tops and no prominent seams that could rub against the skin. 

• Professional Fitting: If you have foot deformities or neuropathy, consider specialist orthopedic shoes. 

Lifestyle factors for skin health 

The health of your skin is a reflection of your systemic health. To keep your tissues robust, your body requires a steady supply of nutrients and oxygen. 

Nutrition and Hydration 

A diet rich in protein, Vitamin C, and Zinc is essential for skin repair. Staying well-hydrated ensures that your skin remains supple and that your circulatory system can move blood efficiently. 

Smoking Cessation 

Smoking is one of the single greatest risks for ulcer formation. Nicotine causes blood vessels to constrict, significantly reducing the amount of oxygen reaching your skin. Quitting smoking improves your circulation and dramatically increases your body’s ability to heal minor wounds. 

Identifying the early signs of infection 

If a break in the skin does occur, you must monitor it closely for signs of infection (cellulitis). An infected wound can lead to systemic illness if not treated promptly with antibiotics. 

Seek medical advice if you notice: 

• Increasing Redness: Especially if the redness is spreading away from the wound. 

• Heat: The skin around the area feels hot to the touch. 

• Swelling: New or worsening swelling in the foot or ankle. 

• Discharge: Foul-smelling fluid or pus leaking from the wound. 

• Systemic Symptoms: Feeling shivery, feverish, or generally unwell. 

To Summarise 

Reducing the risk of ulcers and infections requires a combination of daily skin inspections, meticulous foot hygiene, and the management of underlying vascular conditions. By protecting your feet from trauma and keeping your skin hydrated, you can prevent minor issues from becoming chronic wounds. Maintaining a healthy lifestyle and quitting smoking are also vital steps in supporting your body’s natural healing processes. 

If you experience severe, sudden, or worsening symptoms, such as a cold, pale limb or signs of a rapidly spreading skin infection, call 999 immediately.
