When a child has recurrent colds, the main consideration is the child’s poor immune system or other abnormalities in the child’s respiratory tract, such as tonsillar hyperplasia and adenoid hypertrophy. Poor immune resistance can be enhanced by taking drugs, such as the most common dried jelly powder of spleen aminopeptide, which can significantly enhance immunity. If your child has tonsillar hyperplasia, which often leads to colds due to inflammation of the tonsils, you can go to the hospital to have the tonsils removed. If the child has snoring and breathing difficulties at night and wakes up suddenly due to breath-holding during sleep, consider respiratory diseases caused by adenoid hypertrophy with recurrent respiratory infections. You can go to the ENT department of the hospital for examination and surgical removal if necessary. The most effective way to prevent the disease is to let your child drink more water and strengthen exercise and nutrition.
