Acute tonsillitis is a relatively common throat disease, primarily caused by acute bacterial infection. It leads to redness and pain in the tonsil area. If the inflammatory response is severe, it can also affect normal breathing and swallowing, particularly in cases where the body's resistance is weakened or when accompanied by other diseases, making it easier to trigger tonsillitis. In terms of treatment, antibiotics are generally used to combat the infection, and nebulization and oral traditional Chinese medicine can be considered for auxiliary treatment. The treatment and recovery period is about a week. If the inflammation is mild, recovery may take about five days, but if the inflammation is particularly severe, it might take more than a week. If oral medications are ineffective, intravenous therapy might need to be considered. (Medication should be used under the guidance of a doctor.)

How to treat acute tonsillitis

Acute tonsillitis is a relatively common otolaryngological disease, mainly caused by acute bacterial infection. In terms of treatment, it is first necessary to conduct routine blood tests and indirect laryngoscopy to assess the specific extent of the inflammatory response. Generally, most patients can consider oral medication, commonly used are cephalosporin or penicillin antibiotics. It is also possible to consider combining oral traditional Chinese medicine and nebulization therapy. The general treatment period is about one week, after which most patients will gradually recover and alleviate. If oral medication is ineffective, some patients may need to consider infusion therapy. (Please use medication under the guidance of a doctor)

Is acute tonsillitis contagious?

Acute tonsillitis is an acute infectious inflammation of the tonsils, primarily caused by bacterial infection, though it often also involves viral infection. Acute tonsillitis is mildly contagious; the contagion is not severe or serious, and general isolation is not necessary. It is sufficient to take some precautions in daily life, such as avoiding kissing and the mouth-to-mouth transfer of food. Generally speaking, the contagiousness of acute tonsillitis is relatively weak. Appropriate use of a mask for local isolation, such as wearing a mask to prevent transmission, is sufficient without the need for other special treatments.

How to completely cure chronic tonsillitis?

The definitive treatment for chronic tonsillitis mainly involves surgical removal. Before undertaking the surgery, doctors will conduct a strict assessment to see if there are indications for surgery. Common indications include repeated episodes of chronic tonsillitis, acute outbreaks, or the formation of a peritonsillar abscess, under which circumstances surgery is strongly recommended. Repeated episodes are defined as more than four occurrences per year, at which point surgery should be considered. Furthermore, if the tonsils are so large that they interfere with swallowing, speech, or breathing, such as causing snoring or unclear speech, surgery should also be considered. Moreover, chronic tonsillitis can lead to other diseases since the tonsils are an immune organ, and prolonged chronic inflammation might trigger certain immune-related diseases, such as chronic nephritis, skin diseases, and psoriasis. In such cases, the relevant departments will advise patients to first visit an otolaryngology (ENT) department to have the tonsils removed, which is beneficial for further treatment of the related diseases. Additionally, if the tonsils exhibit signs of benign growths with chronic inflammation leading to lymphatic tissue hyperplasia and cyst formation, surgical removal is recommended to achieve a definitive cure.

How to treat acute tonsillitis?

Acute tonsillitis is mainly caused by an acute bacterial infection, with the most common symptoms being sudden throat pain, and significant redness and congestion of the tonsils, which may also include pus formation if severe. In terms of treatment, oral medication is primarily preferred, generally focusing on antibiotics, and may include nebulization as well as traditional Chinese oral medications. If inflammation is particularly severe and oral medications are ineffective, infusion therapy may be considered. Some patients may also experience fever, thus requiring physical cooling methods, and if the temperature exceeds 38.5 degrees Celsius, antipyretic medications should be considered, along with regular blood tests.

How long to receive IV therapy for acute tonsillitis?

Acute tonsillitis is an acute infectious inflammation of the tonsils, primarily caused by bacterial infection. Therefore, intravenous therapy is required for acute tonsillitis, which indicates that the symptoms of the tonsillitis are severe, often being suppurative tonsillitis. The duration of intravenous treatment generally lasts about three to five days, but it specifically depends on the patient's condition, and can even last longer. After the infection is controlled and symptoms are alleviated, treatment can switch to oral medications for anti-infection. Overall, there is no specific time rule for how long the infusion should last; it is often determined based on the specific condition of the patient.
