What is the disease of severe redness of the mouth and lips that many people do not know. It is an acute febrile illness with typical symptoms of persistent fever, conjunctival congestion, and flushing of the lips, palms, and feet in children under 5 years of age. Currently, the incidence of severe redness of the lips and mouth is increasing in several countries and is causing widespread concern. Regarding the treatment of severe redness of the lips and mouth, there are even cases of life-threatening complications of acquired cardiovascular disease due to improper treatment. As a result, many people want to know how to treat and prevent severe redness of the lips and mouth. The following is a list of ways to prevent and treat severe redness of the lips and mouth, which we hope will be useful. The main symptoms are commonly persistent fever for 5 to 11 days or longer (2 weeks to 1 month), often with a temperature of 39°C or higher, and ineffective antibiotic treatment. Bilateral conjunctival congestion, flushed mouth and lips with chapped or bleeding, and a prune-like tongue are commonly seen. In addition to symptomatic and supportive therapy, the main focus is to counteract vascular inflammation and counteract platelet agglutination, with aspirin and pentoxifylline commonly used. High-dose gammaglobulin drip within 10 days of onset is effective in preventing coronary artery aneurysms. There are more treatment options for severe red congestion of the mouth and lips, but the most common clinical method is pharmacological treatment. Gammaglobulin is usually administered to a patient with a persistent high fever. This drug improves the efficacy against bacterial infectious diseases and brings down the patient’s temperature quickly. Once a patient is diagnosed, he should be treated with medication early, otherwise high fever lasting for many days can easily burn the brain tissue and affect the development of the child later. It is best to use the medication for 4-5 days in a row, depending on the patient’s condition. In general, it is not recommended to use large doses of medication, and each dose should be controlled at 2g/kg/day. After the patient’s body temperature drops, the drug can be discontinued as appropriate. In addition to gammaglobulin, aspirin can also treat severe redness of the lips and mouth. However, aspirin has certain side effects and should not be administered in large doses. The dosage for children should be controlled in a certain range so as to treat the disease without causing side effects. After the temperature of the child drops, the dosage dose should be reduced from the original 30-50mg to 10-30mg. When the dosage is reduced to 3-5mg, and then continue to use the medicine for two months, the child’s disease will be cured. Another point to note when using aspirin is that aspirin is not good for liver function. When taking it, observe the condition of the person using it and check whether the patient has any abnormalities such as bleeding or nosebleeds. If abnormalities occur, the drug should be stopped immediately. Can severe congestion of the lip with red color be cured? Under normal circumstances, severe red congestion of the lip can be cured, but it may recur, and patients should take preventive measures after being cured. Patients should pay attention to diet, rest and proper hydration in daily life. When one’s resistance decreases, exercise and supplementation are needed to enhance physical fitness. If the disease relapses, it is best not to exercise, and should rest in bed and ensure sufficient sleep. Work, also pay attention to the combination of work and rest, do not often work overtime and stay up late, overthinking.
