Laryngitis can be treated by eating watermelon, which is completely fine. Laryngitis refers to an acute inflammatory infection of the throat, often caused by the invasion of Staphylococcus aureus or Streptococcus hemolyticus, and it commonly occurs in infants and young children. Due to the loose mucous membranes in the throats of infants and young children, once an inflammatory infection occurs, it can easily cause the patient to have fever, voice changes, hoarseness, a bark-like cough, and the patient may also experience breathing difficulties. In severe cases, it may lead to suffocation or even death. In terms of treatment, patients with laryngitis must receive symptomatic anti-inflammatory treatment, and can take oral or intravenous antibiotics, such as cephalosporin antibiotics, which are effective. Patients also need to use corticosteroids to reduce acute congestion and swelling in the throat, adhere to a light diet, avoid spicy and irritating foods, and eat more vegetables and fruit to gradually improve. (Please use medication under the guidance of a professional doctor.)
