Warts: Types, Causes, and Effective Removal Methods

Warts: Types, Causes, and Effective Removal Methods

Types of Warts

Common Warts

Common warts, also known as verruca vulgaris, typically appear on the hands, fingers, and around the nails. They have a rough, raised surface and may have tiny black dots, which are blood vessels. Common warts are usually harmless but can spread to other areas if left untreated.

Plantar Warts

On the bottoms of the feet, plantar warts grow, frequently causing pain and discomfort while walking. These flat could contain little black specks in the centre. Plantar warts can grow inward as a result of the pressure placed on the feet, making them challenging to treat.

Flat Warts

Small, smooth, flesh-colored warts known as flat warts frequently develop in groups. They frequently reside on the face, neck, hands, and legs. Flat warts are more common in children and teenagers and are spread easily by touching or shaving.

Filiform Warts

Filiform warts have long, narrow projections that resemble threads or fingers. They typically appear around the mouth, nose, or eyes and can be flesh-colored or slightly darker. Filiform warts can be easily irritated or bleed if scratched.

Genital Warts

A sexually transmitted infection called genital warts is brought on by specific HPV strains. They might be little or huge, flat or cauliflower-shaped, and they can develop on the vaginal and anal sites. Warts on the genital area should not be treated with over-the-counter medications and instead require medical treatment.

Causes of Warts

The HPV virus, which causes warts, enters the body through minute skin breaks or cuts. In warm, damp settings like locker rooms, swimming pools, and public showers, the virus thrives. Certain factors, such as a weakened immune system or direct contact with infected individuals or surfaces, increase the risk of developing warts.

Symptoms of Warts

Warts are usually painless unless they appear on weight-bearing areas like the feet. Common symptoms of warts include:

  • Rough, raised skin growths
  • Small black dots or “seed” spots
  • Clusters or single growths
  • Itching or irritation (especially in filiform warts)
  • Discomfort or pain while walking (in plantar warts)


Cryotherapy involves freezing the wart with liquid nitrogen, causing it to blister and eventually fall off. This procedure is commonly performed by healthcare professionals and may require multiple sessions for complete 脫疣. Cryotherapy can be effective but may cause temporary discomfort and blistering.

Laser Treatment

Laser treatment uses a focused beam of light to target and destroy the wart tissue. It is typically performed by dermatologists and may require local anesthesia. Laser treatment can be an effective option for stubborn or recurrent warts, with minimal scarring as a side effect.

Surgical Removal

In some cases, surgical removal of warts may be necessary. This procedure is performed under local anesthesia, and the warts are cut out or burned off. Surgical removal is usually reserved for large or resistant warts and may result in scarring.

Prevention of Warts

To reduce the risk of developing warts or spreading them to others, it is important to follow these preventive measures:

  • Avoid touching warts on yourself or others.
  • Keep the skin clean and dry.
  • Wear flip-flops or sandals in public showers or pool areas.
  • Avoid biting nails or picking at hangnails.
  • Use condoms and practice safe sex to prevent genital warts.

When to Seek Medical Help

While most warts can be treated at home, there are certain circumstances where medical attention is necessary:

  • Genital warts or suspected sexually transmitted infections.
  • Warts that cause significant pain, discomfort, or interfere with daily activities.
  • Warts that change in color, size, or appearance.
  • Warts that recur despite previous treatment attempts.
  • Warts in individuals with compromised immune systems.

If you experience any of the above, it’s important to consult a healthcare professional for proper evaluation and guidance.


Warts are a common skin condition caused by the human papillomavirus. They can be unsightly and cause discomfort, but with the right treatment approach, they can be effectively removed. Whether using over-the-counter treatments, home remedies, or seeking medical procedures, it’s important to address warts promptly and follow preventive measures to minimize their occurrence.
