Psoriasis, commonly known as “psoriasis”, has a complex etiology that is related to susceptibility genes, environment, diet, poor lifestyle habits, mood and so on. Most people have a history of upper respiratory tract infections (including tonsillitis and laryngitis) before the onset of the disease. In the initial stage, if the disease is acute psoriasis, it can be cured in part and turned into chronic psoriasis in part by standardized treatment and correct health guidance. If acute punctate psoriasis recurs and the tonsils are often inflamed, tonsillectomy can be considered. Other types of psoriasis, often prone to recurrence, vary in frequency, duration and severity from person to person. Patients with psoriasis, in addition to standardized treatment in regular hospitals, should also strive to avoid cold and flu, avoid smoking, alcohol, spicy and stimulating food, try not to eat seafood, beef and mutton and other hairy products, regular life, avoid staying up late and straining, maintain a relaxed mood, relaxed spirit, appropriate more sunshine, perseverance and persistence to adhere to treatment can achieve relatively ideal results.
