Introduction

Viral and bacterial infections are the most common causes of tonsillitis, with bacterial infections being the most frequent. When the body’s immune resistance is low, the tonsils—whose inherent resistance is relatively weak—become susceptible to invasion by bacteria and viruses, leading to inflammation. Tonsillar infection may also occur during “heatiness” (a traditional Chinese medicine concept referring to internal heat or inflammatory conditions). In modern society, many people enjoy consuming spicy and stimulating foods.

The tonsils remain critically important to the human body, helping defend the mouth and nose against invading bacteria and viruses. However, due to their unique anatomical location, they are also particularly susceptible to external pathogens. So, what causes tonsillitis?

Causes of Tonsillitis

Viral and bacterial infections are the most common causes of tonsillitis, with bacterial infection being the most frequent. When the body’s immune defenses are weakened, the tonsils—whose inherent resistance is relatively low—become vulnerable to invasion by bacteria and viruses, leading to inflammation. Tonsillitis may also occur during “heatiness” (a traditional Chinese medicine concept referring to internal heat or inflammatory conditions). In modern society, many people enjoy spicy and stimulating foods, which can easily trigger tonsillitis. Therefore, a light, mild diet is generally recommended. If tonsillitis results from “heatiness,” drinking warm water and cooling herbal teas may help reduce inflammation and effectively alleviate symptoms. When overall immunity is compromised, various viruses and bacteria can invade the body, resulting in tonsillar inflammation.

In treating tonsillitis, antibiotics such as erythromycin, penicillin, and lincomycin are indicated when the condition is caused by bacterial infection. If fever accompanies the infection, aspirin may be used for symptomatic relief. After approximately three days of treatment, clinical progress should be assessed. If no improvement is observed, corticosteroids—such as prednisone, dexamethasone, or hydrocortisone sulfate—may be required. During pharmacological treatment, it is essential to strictly follow the physician’s instructions and administer adequate dosages. Medication must not be discontinued prematurely upon symptom relief, as this significantly increases the risk of recurrent tonsillitis.

Regular rest is essential to prevent tonsillitis triggered by overwork; consistent physical exercise is also recommended to strengthen the body’s natural immunity. We hope this information proves helpful to you.

What Causes Tonsillitis?

Tonsillitis is primarily caused by infections—either bacterial or viral. Common precipitating factors include prolonged fatigue, consumption of large amounts of spicy foods, excessive smoking and alcohol intake, and the common cold. For treatment, mild cases may be managed with oral medications; however, if obvious symptoms such as purulent tonsillar exudates or high fever are present, more aggressive intervention may be required.

What Causes Tonsillitis?

Tonsillitis may be caused by infection with beta-hemolytic streptococcus. However, other pathogens—including *Staphylococcus*, *Streptococcus pneumoniae*, and adenovirus—can also cause tonsillitis. In clinical practice, mixed bacterial and viral infections are relatively common, and even anaerobic infections have been reported. Risk factors include exposure to cold temperatures, high ambient humidity, excessive fatigue, heavy smoking or alcohol consumption, or inhalation of toxic or harmful gases.
