Chronic tonsillitis often comes as a result of an acute onset that is not systematically treated, and the incidence of this disease is about 22% in adolescents aged 6 – 15 years. In fact, chronic tonsillitis often appears as an acute attack, which not only affects learning and life, but also the bacteria and toxins in the tonsillar crypts can form focal infections and metaplasia, producing various complications, such as rheumatoid arthritis, rheumatic fever, heart disease, acute nephritis, etc.; some children with tonsillar and proliferative hypertrophy may develop upper respiratory obstruction, causing obstructive sleep apnea, which seriously affects children The growth and development of children, and even cause facial changes, such as high arched hard palate, uneven teeth, shortened upper lip, small jaw, etc.. The danger cannot be ignored. Therefore, it is important to detect and treat tonsillitis as early as possible to avoid some serious complications. Chronic tonsillitis usually does not have serious symptoms, but if you pay close attention, you can still find the following symptoms: discomfort in the throat, dryness, itching or mild pain, etc.; repeated cold and flu or acute attack of tonsils, which can occur 1 or 2 times in a month or two. Bad breath when speaking and a feeling of swelling and pain in the tonsillar area. There is often an irritating cough and a feeling of foreign body obstruction; some feel difficulty in swallowing and speaking because the tonsils are particularly enlarged. Due to frequent swallowing of tonsillar secretions, stimulation of the intestines and stomach can lead to indigestion and nutritional disorders. Due to the absorption of bacteria and toxins in the niche by the blood, symptoms such as low fever, headache, fatigue, and weakness of the limbs may occur. Parents should take their children to the doctor in time if they have the above symptoms. For the treatment of chronic tonsillitis, surgical removal was advocated in the past, but because the tonsils have a certain immune function, a cautious attitude is taken, especially in children and young people with simple chronic tonsillitis, conservative treatment is appropriate. However, if the tonsils are often repeatedly inflamed and affect work and study, or if they have become foci of infection, they need to be surgically removed as soon as possible.
