Hi, Psoriasis is over active defense mechanism of the body (The T cells production) that supersedes perishing/shedding off of the older cells on external skin thus allowing overgrowth on the skin surface making it irritated, itchy & inflamed. This growth is triggered by many things (given below) which are to be presented on a personal level to avoid triggering of the disease symptoms. Triggering factors are- - Streptococcal throat infection, - Avoid exposure to the infection/infected persons (by using a mask in crowded places/meeting a throat infected person), try to enhance resistance by a healthy diet with vitamins, minerals & proteins. Exposure to moderate sunlight daily. - Avoid exposure to cold. - Avoid allergic rash (recognize allergens and avoid them). - Keep the skin clean & well moisturized. - Give emotional support to the child. A positive approach of father & mother is imparted to child & it helps in psoriasis management. Take help of a psychological therapist as per need. * Remember apart from moisturizers/creams with vitamin D & prescribed steroids used as per need /shampoos with coal tar & salicylates. Avoiding triggers takes a major part in psoriasis management. The disease is known to vanish over the time so give patience & go on managing & avoiding it till it vanishes. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Vasudha Jayant Athavale, General & Family Physician
