wart when to seek care

Overview

A wart is a small, rough growth on the skin caused by a virus called human papillomavirus (HPV). Warts are usually harmless and often go away on their own, but some people prefer to have them treated, especially if they are painful or visible.

Yes, warts are extremely common. Most people will get at least one wart at some point in their lives.

Anyone can get warts, but they are most frequent in children and teenagers. People with weakened immune systems, such as those taking certain medicines or with chronic health conditions, may also get more warts or have warts that are harder to treat.

Symptoms

Common symptoms

• A small, raised bump with a rough surface that feels like a very hard pimple
• Skin-colored, pink, or slightly brownish growth
• Tiny black dots inside the wart (these are small clotted blood vessels)
• May appear on hands, fingers, knees, elbows, or the bottom of the feet (plantar warts)
• Usually painless, but warts on the feet may be sore when you walk or stand

Symptoms in children

• Warts in children often look the same as in adults, but they can appear more frequently on the hands, knees, and face because children are more likely to have scrapes and scratches.
• Children may be more prone to warts because their immune systems are still developing.
• Some warts in children may disappear without any treatment, but if they bother the child, a doctor can discuss safe options.

Symptoms in older adults

• Warts in older adults are less common, but they can still appear, especially on the hands and feet.
• Older adults have thinner skin and may have other skin conditions that can make warts look different.
• If you are older and develop a new growth on your skin, it is wise to have it checked by a doctor to rule out other causes.

Causes

Main causes

• Warts are caused by the human papillomavirus (HPV).
• The virus enters the skin through tiny cuts, scrapes, or weak spots.
• It causes the top layer of skin to grow quickly, forming a wart.
• HPV thrives in warm, moist environments, such as shared showers, swimming pools, and damp towels.

Risk factors

• Coming into direct contact with a wart on someone else
• Touching objects that have touched a wart, like towels, razors, or floors in public showers
• Biting your nails or picking at hangnails, which creates openings for the virus
• Having a weakened immune system from illness, medication, or chronic disease

When to see a doctor

See a doctor urgently if:

• A wart on your face, genitals, or mouth (special care needed)
• A wart that is painful, bleeding, or growing quickly
• A wart that has black streaks, an unusual look, or changes in shape or color
• If you have diabetes, poor circulation, or a weak immune system, and you develop a wart on your foot or leg
• If you have tried over-the-counter treatments for several weeks and the wart is not improving

Book a routine appointment if:

• If a wart is causing embarrassment or interfering with daily activities, you can schedule a routine appointment with your doctor.
• If you have multiple warts and want to discuss options for removing them.
• If you want to confirm that a skin growth is really a wart and not something else.

Diagnosis

A doctor can usually tell if you have a wart just by looking at it. They may also use a magnifying lens or a thin blade to gently scrape a bit of the top layer to see the typical pattern of a wart.

Tests that may be done

• Usually no tests are needed.
• In rare cases, if a growth doesn't look like a typical wart, a doctor may take a small sample (biopsy) to send for laboratory testing.

What to expect at your appointment

During an appointment, the doctor will ask about your medical history and examine the growth. They may look at other areas of your skin, especially if you have several warts. The visit is usually quick and painless. Afterward, the doctor will talk with you about whether treatment is needed and what your options are.

Treatment

There are many ways to treat warts, from simple home remedies to procedures performed by a healthcare professional. The goal is to gently remove the wart and let your skin heal. Some treatments work better for certain types of warts, so a doctor can help choose the best approach.

Self-care at home

• Wash your hands regularly and dry them well.
• Avoid picking, scratching, or biting at a wart, as this can spread the virus.
• You can cover a wart with a small bandage to help prevent spreading.
• For plantar warts (on the bottom of your feet), wearing comfortable shoes and using cushioned insoles may help reduce pain.
• Some pharmacy products can be applied at home, but always follow the instructions and stop if the skin becomes very sore.

Medical treatments

A doctor may offer treatments such as freezing the wart with a cold spray, applying prescription creams or solutions, or using lasers or lights. These methods aim to destroy the wart tissue. The doctor will decide which method is safest for your skin type and situation. They may also discuss boosting your immune system's response, sometimes with special therapies. No specific drug names are given here because the right choice is highly individual.

When is surgery considered?

Surgery is rarely needed for warts. It may be considered if a wart is very large, causes persistent pain, or does not respond to other treatments. A minor surgical procedure to remove the wart is usually done under local anesthetic in a doctor's office or clinic.

Living with this condition

For most people, warts are a minor nuisance. You can live normally, but take simple steps to avoid spreading the virus. If a wart is on your hand, try to keep it covered when you touch communal items. If it is on your foot, wear shower shoes in gyms and public pools.

Lifestyle tips

• Practice good hand hygiene to reduce the risk of spreading warts.
• Do not share towels, razors, socks, or other personal items.
• Keep your skin healthy and moisturized to avoid cracks that let the virus in.
• After swimming, dry your feet thoroughly, especially between the toes.

Diet and exercise

Eating a balanced diet with plenty of fruits and vegetables supports your immune system, which helps your body fight off the virus. Regular exercise and good sleep are also beneficial. There is no specific diet that cures warts, but a healthy lifestyle can help your skin recover.

Mental health and emotional wellbeing

Warts can sometimes make people feel self-conscious, especially if they are on visible areas like the face or hands. It is important to remember that warts are very common and not something to be ashamed of. If you feel worried or distressed, talking to a doctor or a trusted person can help. Many treatments are available, and most warts eventually clear.

Prevention

Warts are not always easy to prevent because the virus is widespread. But you can reduce your risk by practicing good hygiene, avoiding direct contact with warts, cleaning cuts well, and drying your skin completely after bathing or swimming.

Vaccines

There is a vaccine for certain types of HPV that can prevent some warts, including genital warts and some types of warts on the hands and feet. This vaccine is usually recommended in childhood or young adulthood. Ask your healthcare provider if it is appropriate for you.

Screening programmes

There is no routine screening test for warts. However, if you notice any new growth or a change in a spot, seeing a doctor is a good idea for peace of mind.

Complications

If left untreated

• Warts may spread to other parts of your body or to other people.
• Warts can become painful, especially on the soles of the feet, and may make walking uncomfortable.
• Rarely, a wart can become infected or bleed, but this is not common.
• In people with weakened immune systems, warts may grow larger, more numerous, and be more difficult to treat.

Long-term outlook

The outlook for warts is very positive. Many warts disappear on their own without treatment. For those that persist, there are many safe and effective options to remove them. With a little patience and guidance from a healthcare professional, most warts can be successfully resolved, and any discomfort is usually temporary. Your skin is remarkable at healing, and you have a wide range of support available.
