Garlic is not allowed to be eaten by patients with laryngitis. Laryngitis can lead to congestion and swelling of the mucous membrane in the throat, and garlic is a strong stimulant, so the stimulation of the mucous membrane in the throat will be aggravated after eating garlic, causing more congestion and swelling of the mucous membrane, thus aggravating the condition of laryngitis. Laryngitis is mostly caused by bacterial infection, which can cause congestion and swelling of the mucous membrane in the throat, resulting in pain, foreign body sensation, and fever in the throat. Patients need to eat a light diet, avoid spicy and irritating food, and give antibiotics such as cefprozil, amoxicillin clavulanate potassium, metronidazole, etc. The course of treatment is usually one week. During the period of the disease, it is necessary to take more rest and avoid overexertion.
