The treatment of flat warts mainly includes several aspects: physical therapy, topical medication therapy, and systemic medication therapy. Physical therapy for local application includes methods such as laser, cryotherapy, and microwave. This is mainly suitable when there are few skin rashes, as fewer lesions do not cause much trauma. If there are many lesions, it is recommended to use topical medication therapy and oral or injectable medication therapy. Topical medication therapy includes antiviral medications like acyclovir and penciclovir, topical immunomodulatory drugs like interferon, which also have antiviral effects, as well as topical fluorouracil and topical retinoids. Additionally, there is oral medication therapy, which includes oral antiviral drugs such as acyclovir, as well as oral retinoids. There are also medications available to boost immunity and modulate the immune system, such as thymosin and interferon. However, all these treatments should be carried out under the guidance of a doctor.

How to deal with flat warts on the eyes?

Flat warts are caused by infection with the Human Papillomavirus, also commonly known as HPV. This disease is highly contagious and recurrent, and it is somewhat related to reduced immunity. If they appear near the eyes, it is advisable to go to the dermatology department of a regular hospital and use laser treatment, followed by the external application of antiviral ointment. Regular exercise should be enhanced to boost immunity. If there are many warts around the eyes, and they have been there for a long time with poor treatment outcomes, one can consider using wart immunization implantation. After removing the wart tissue, it is made into an antigen vaccine and implanted subcutaneously, allowing the body to produce antibodies to fight the virus. This method causes minimal trauma and is quite effective.

Can people with flat warts eat eggs?

Flat warts can be eaten with eggs. Eggs are to be avoided by some patients with allergic diseases who are sensitive to eggs; some people are allergic to egg whites, while others may react to egg yolks. However, the pathogenesis of flat warts is not related to allergies. It is a viral disease caused by infection with HPV type 3 virus, commonly found on the face and forearms. The typical skin lesions are rice grain or soybean-sized, flat, elevated papules that are round or oval-shaped. The surface is smooth and hard, with a normal skin color or light brown, often appearing suddenly in large, dense numbers. After scratching, the lesions can appear bead-like, arranged along the direction of scratching, forming an autoinoculation reaction. Thus, the worsening of flat warts is due to scratching and self-spreading; the more one scratches, the more warts appear. The condition of flat warts is related to the individual's immunity. When immunity is low, it’s easier to be infected. When immunity is high, resistance is stronger, and some patients may see the warts resolve on their own, although a few may relapse. Therefore, eating eggs is unrelated to flat warts.

Is flat wart serious?

Flat warts are caused by an infection with the human papillomavirus, commonly known as HPV. This disease currently has a particularly high incidence rate, with most people having one or more flat warts on their skin. Once they appear, they can be completely cured with proper treatment. This condition is not considered particularly severe, but it is highly contagious and recurrent. When bathing at home, it's important to use separate towels or washcloths from other family members to prevent cross-infection. It is also advisable to avoid spicy and irritating foods, avoid staying up late, exercise regularly, and strengthen the immune system for a faster recovery from the disease.

Can flat warts heal on their own?

Flat warts are caused by an infection with the papillomavirus. This disease has a very low rate of self-healing and generally requires treatment to resolve because flat warts have strong contagiousness and recurrence. Once they appear, it is imperative to seek formal treatment immediately; waiting until they multiply will only increase the difficulty of treatment. Common treatments include laser or cryotherapy. Conventional oral and topical medications are particularly slow in effect, and most patients do not have very good outcomes. Immunotherapy for warts can also be used. These treatments are available in the dermatology departments of standard hospitals. It is crucial to avoid spicy and irritating foods, not to stay up late, and to refrain from repeatedly scratching when itching occurs. Scratching can cause wounds where the virus implants and proliferates, leading to the development of linear or band-like clusters of flat warts.
