Lichen planus is an autoimmune disorder. It develops when white blood cells activate for no apparent reason, triggering an inflammatory response in the body. The inflammation causes small lesions to form on the skin or inside the mouth. Treatment often involves medications that minimize inflammation, which can help to relieve symptoms and heal lesions. While dietary changes aren’t usually part of most treatment plans, they can sometimes prevent a flare-up.
Diet
It appears that certain foods can trigger oral lichen planus, particularly when you have a history of the disorder. Both acidic and spicy foods are known to cause lesions, but only those that develop in the mouth, according to the Mayo Clinic website. Avoiding these foods, however, will not prevent flare-ups of lesions that develop on the skin. Another form of treatment is necessary to manage this form of the condition.
Development
Although the cause of lichen planus isn’t well understood, medications and medical conditions are thought to contribute to its development, so other dietary changes aren’t likely to help. Medications used to prevent or treat high blood pressure, heart disease, arthritis, hepatitis B, pain and influenza have been linked to this condition. If a medication is the cause, you should see an improvement if the drug is eliminated. Allergens and hepatitis C have also been known to trigger lichen planus. Talk to your doctor to determine the best course of treatment.
Treatment
Corticosteroids are often the first line of defense. These medications can reduce inflammation, thereby relieving symptoms. They can be administered topically, orally or intravenously, depending on the form of lichen planus. You may also see an improvement in lesions with retinoids, antihistamines, immune-suppressing medications and nonsteroidal ointments. Some people respond favorably to phototherapy, as well.
Warning
Although lichen planus isn’t usually harmful, it can lead to some serious complications, especially when left untreated. Oral lichen planus can narrow the esophagus, whereas the epidermal variety can damage vulvovaginal tissue if the lesions form within the vagina.
