What causes red and swollen throats in children?

When children are young, some problems will always occur. Because their resistance is relatively weak, whenever they catch a cold, they will always be accompanied by redness and swelling of the throat, and even fever. Many parents will be anxious and at a loss when their children are sick, and always complain that the doctor uses bad medicine. In fact, there are certain reasons for the redness and swelling. Let me introduce them to you!

Children's throat swelling is mainly caused by tonsillitis, the main reasons are:

Pathogens are transmitted through droplets, direct contact, etc., and usually hide in the tonsil pits. When the human body's resistance is weakened due to fatigue, cold or other reasons, the pathogens multiply rapidly and cause illness. The inflammation starts in the tonsils and then spreads throughout the tonsils.

In acute inflammation, the tonsil parenchyma is congested and infiltrated with polymorphonuclear leukocytes, and yellow-white spots can be seen on the mucosal surface. The tonsils are obviously swollen and many small abscesses may form. The purulent exudate composed of cellulose, desquamated epithelium and pus cells in the pits is discharged to the pit openings, so pus spots can be seen at the pit openings of the tonsil.

The pathological changes of chronic inflammation are obvious, with active proliferation of lymphocytes and reticular cells and hypertrophy of tonsils. The mucosal epithelium of the pits is thickened, the surface is hyperkeratotic, or small ulcers form. Keratin, inflammatory exudate, desquamated epithelial cells, leukocytes, bacteria, etc. mix to form a cheesy plug that blocks the opening of the pit. Long-term inflammation can cause occlusion of small blood vessels in the tonsils and degeneration of lymphatic tissue, which is gradually replaced by connective tissue. After that, the tonsils will gradually shrink and finally lead to tonsil fibrosis. The opening of the pit is narrowed due to scarring, and its contents are difficult to expel, often becoming a lesion.

After reading these introductions, you may have a certain understanding of the redness and swelling of your child's throat. Children's illness is not accidental. You can only pay more attention to your child's diet, let your child maintain good hygiene habits, wash hands before eating, and let your child exercise more, which can greatly improve your child's resistance.
