Patients have mucous phlegm in their throat after eating, often due to the influence of factors that patients eat. For example, if patients eat spicy food or overly salty or hot food, it may lead to congestion and inflammation of the mucous membrane of the pharyngeal cavity or tonsils, which will form inflammatory exudates leading to mucus formation, and patients will have an obvious feeling of foreign body in the throat. It is recommended that patients must chew and swallow slowly, avoid overly spicy and salty food, and at the same time must strengthen the mouth rinsing after meals to avoid the retention of food residues, which may aggravate the infection. If there is mucous phlegm in the throat, you can consider applying Throat Sword spray or containing iron flute tablets to treat the condition.
