cellulitis diet considerations

Overview

Cellulitis is a bacterial infection of the deeper layers of your skin and the tissue just beneath it. It usually starts as a red, swollen, tender area that feels hot to the touch, often on the leg. The infection happens when bacteria enter through a cut, crack, or break in your skin.

Yes, cellulitis is a common skin infection. In the UK, many people are treated for cellulitis each year, and it is a frequent reason for GP visits and hospital stays.

Anyone can get cellulitis, but it is more likely if you have a break in your skin, a weakened immune system, diabetes, poor circulation, or swelling in your arms or legs. Older adults and people with long-term skin conditions are also at higher risk.

Symptoms

Common symptoms

• A red, swollen area of skin that feels tender and warmer than the skin around it
• The red area can spread quickly
• Pain or soreness in the affected area
• The skin may look shiny or feel tight
• A fever, chills, or generally feeling unwell

Symptoms in children

• Cellulitis in children often appears on the face or around the anus (from strep bacteria)
• The skin may be red, swollen, and painful
• Children may be fussy, have a fever, or refuse to move the affected limb

Symptoms in older adults

• Symptoms can be more subtle or appear suddenly
• Confusion or drowsiness may be the first sign of an infection
• Swelling and redness may be less noticeable but still present
• The infection can worsen more quickly, so early medical advice is very important

Causes

Main causes

• Bacteria, usually strep or staph, entering through a break in your skin
• Cracks in the skin from athlete's foot, eczema, or dry skin
• Insect bites, cuts, scrapes, burns, or surgical wounds
• Skin ulcers or a previous injury that did not heal cleanly

Risk factors

• Diabetes, especially if blood sugar levels are not well controlled
• Swelling in your limbs (lymphoedema) or poor blood flow
• A weakened immune system from illness or certain medicines
• A history of cellulitis before
• Overweight or obesity

When to see a doctor

See a doctor urgently if:

• Any red, swollen, or painful area of skin that is spreading or getting worse
• A fever or feeling hot and shivery
• Cellulitis on your face or near your eyes
• If you have diabetes or a weakened immune system

Book a routine appointment if:

• If you have had cellulitis more than once, ask your doctor about ways to reduce future episodes
• If you have ongoing skin conditions like eczema or athlete's foot, seek advice on controlling them

Diagnosis

A doctor will look at your skin and ask about your symptoms and recent injuries. They will usually be able to diagnose cellulitis from the appearance and feel of the area.

Tests that may be done

• In most cases, no tests are needed
• If the infection is serious or unusual, a doctor may take a swab or small sample from the affected area
• Blood tests can help check how severe the infection is
• In rare cases, an ultrasound or other scan may be used to look for abscesses or deep infection

What to expect at your appointment

Your doctor will likely prescribe antibiotics and ask you to take the full course, even if you start to feel better. They may also suggest raising the affected limb and taking over-the-counter pain relief. Follow up if things do not improve within 48 hours or if symptoms get worse.

Treatment

Cellulitis is usually treated with oral antibiotics. Most people start to feel better within 24 to 48 hours. It is essential to complete the entire antibiotic course and to keep the affected area clean and rested.

Self-care at home

• Finish the full course of antibiotics exactly as prescribed
• Rest and raise the affected limb to help reduce swelling
• Drink plenty of fluids to stay hydrated
• Use a clean, dry dressing if the area is open or weeping
• Avoid scratching or picking at the skin

Medical treatments

Doctors typically prescribe antibiotic tablets or liquid. For more serious infections, you may need antibiotics given through a drip in the hospital. Pain relief such as paracetamol or ibuprofen may be recommended — ask your pharmacist which is suitable for you. Never share antibiotics or use leftover medicines.

When is surgery considered?

Surgery is rarely needed for cellulitis. It may be required if a collection of pus (an abscess) forms under the skin, which would need to be drained by a healthcare professional.

Living with this condition

During recovery, take it easy. Rest the affected area, keep it clean, and watch for any signs of the infection getting worse. It can take a week or more for the redness and swelling to fully go down, even after you start feeling better.

Lifestyle tips

• Moisturise your skin daily to prevent cracks and dryness
• Treat any underlying conditions, like athlete's foot, promptly
• Wear protective footwear when outdoors to avoid cuts
• If you have diabetes, keep your blood sugar levels within your target range

Diet and exercise

A balanced diet supports your immune system and helps your body heal. Include plenty of fruits, vegetables, whole grains, and lean proteins. Foods rich in vitamin C (like oranges and berries) and zinc (like nuts and seeds) can support wound healing. Stay well hydrated. Gentle movement, such as walking, is usually fine once you feel able, but keep the affected limb raised when resting. Talk to your doctor before starting any new exercise, especially if you have heart or circulation problems.

Mental health and emotional wellbeing

Having cellulitis can be uncomfortable and may disrupt your daily routine. It is normal to feel anxious or frustrated while waiting to get better. Reach out to people close to you, and if you notice persistent low mood or worry, mention it to your GP or practice nurse.

Prevention

You can lower your chances of getting cellulitis by looking after your skin and treating any breaks or injuries quickly. Keep your skin clean, use moisturiser, and manage conditions like eczema or dry skin. If you have athlete's foot, treat it early to avoid cracks between your toes.

Vaccines

There is no vaccine to prevent cellulitis itself. However, keeping up to date with routine vaccines, including the flu, pneumonia, and other recommended jabs, can help reduce your risk of infections overall. Ask your doctor what is right for your health.

Screening programmes

There is no routine screening for cellulitis. Regular check-ups for conditions like diabetes are important because controlling blood sugar helps prevent skin infections.

Complications

If left untreated

• The infection can spread deeper into the skin and tissue
• It can enter the bloodstream and cause a serious whole-body infection (sepsis)
• A pocket of pus (abscess) may form and need draining
• Sometimes the underlying skin is damaged, leading to permanent swelling (lymphoedema)

Long-term outlook

With prompt treatment, most people with cellulitis make a full recovery within a week or two. Even if you need hospital care, the outlook is generally very good. Following your treatment plan and looking after your skin are the best ways to ensure a smooth recovery and reduce the chance of it returning.
