Since children have a lower immune system, they are also vulnerable to invasion by pathogens. When children catch a cold, resulting in a cold, and have a weak immune system, pathogens can multiply rapidly in the tonsils. 1. Use antiseptic and anti-inflammatory drugs: It has the advantage of not having to remove the tonsils. The disadvantage is that the pathogens hidden in the tonsils cannot be completely removed. It is likely to appear whenever the immunity of children decreases. When it appears more often, it may form lesions and induce other diseases. 2. Removal of tonsils: Children who have enlarged tonsils for the first time do not need to undergo tonsillectomy. When the tonsils are enlarged and block the breathing passage, resulting in unclear pronunciation and difficulty in swallowing food in children, surgery is required. When the tonsils become inflamed several times and cause other diseases, surgery is also feasible. 3. Prevention: Children are younger and their organs are more fragile, and the use of medication can have some effects on them. Therefore, it is still necessary to focus on prevention. Parents should not develop the habit of picky eating in their children, and all kinds of food should be eaten in order to take in enough nutrition. When the weather and air quality are good, parents can exercise with their children to let them know that exercise can strengthen their body and the importance of strengthening their body, and to cultivate the habit of exercise.
