Tonsils play a key role in our immune system by protecting against infections. Common issues include inflammation due to viral or bacterial infections, leading to sore throat, swelling, and difficulty swallowing. Symptoms may also include fever and bad breath. Treatments range from home remedies, like saltwater gargles, to medications or antibiotics for bacterial infections. In severe cases, a tonsillectomy might be recommended. Preventive tips include good hygiene, staying hydrated, and avoiding close contact with infected individuals.
