When the above symptoms occur, the first consideration is throat symptoms caused by gastric malfunction, and a combination of laryngoscopy and gastroscopy is needed to assist in the diagnosis. If there is gastroesophageal reflux disease, the contents of the stomach can burn the mucous membrane of the throat during reflux, causing edema, which can easily cause this foreign body sensation when it clings to the surrounding tissues. When treating this type of disease, the first thing to do is to change your eating habits, reduce the consumption of spicy and irritating foods, eat more fresh vegetables and fruits, quit smoking and alcohol, avoid exposure to dust and irritating gases, maintain oral hygiene, and use drugs that inhibit stomach acid and promote gastrointestinal tract dynamics.
