When we talk about tonsils, we often refer to the palatine tonsils, which are a pair of tonsils located deep in the human mouth on both sides of the lateral wall of the isthmus, in the tonsillar fossa between the palatolingual and palatopharyngeal arches, commonly known as the tonsils. The tonsils can produce lymphocytes and antibodies, so they have anti-bacterial and anti-viral immune defense functions. As the tonsils are located in the throat, they are closely related to the outside world, and the temperature and humidity in the tonsils are very suitable for bacterial reproduction, so when the body’s resistance is lowered, it is easy for germs to attack and inflammation. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. As the tonsils of patients with chronic tonsillitis are often enlarged, it can seriously affect breathing (snoring or open-mouth breathing), prevent swallowing, cause slurred speech, and cause the accumulation of inflammatory secretions in the nasopharynx, which can obstruct the pharyngeal opening of the eustachian tube and cause sinusitis, otitis media, or cause a persistent cough. Chronic tonsillitis can not only cause infections in neighboring organs through the spread of inflammation, but more importantly, the bacteria accumulated in the tonsillar crypt continuously secrete toxins and spread to the whole body through the vascular network around the glandular fossa, thus causing many systemic diseases, such as secondary rheumatic fever, rheumatoid arthritis, rheumatic heart disease, acute nephritis and hypothermia without significant cause, which can cause immune damage to organs such as kidney, heart and joints. This can cause immune damage to the kidney, heart and joints. At this point, the tonsils become the “culprit” of the disease. Therefore, the occurrence of chronic tonsillitis should be taken very seriously. The main feature of chronic tonsillitis is the history of repeated acute attacks. Patients usually have no obvious conscious symptoms, but in between attacks, they usually show symptoms such as throat discomfort, foreign body sensation, dryness, itching, irritating cough and bad breath. The typical manifestations of acute attacks include sore throat, bad breath, enlarged tonsils, headache, weakness of limbs, fever, etc. If accompanied by high fever, it may lead to acute myocarditis or even life-threatening. Patients with recurrent chronic tonsillitis or tonsillitis causing complications are recommended for surgical treatment (minimally invasive surgery). However, the most important thing in the prevention and treatment of chronic tonsillitis is prevention: we recommend avoiding colds and strengthening physical fitness with exercise.
