Introduction

Reasons why plums should not be consumed when having a cough include acidic irritation, increased mucus secretion, increased gastrointestinal burden, possible allergic reactions, and interference with medication absorption. If you have any concerns, it is recommended to seek timely medical advice. To alleviate cough symptoms and avoid unnecessary health risks, it is advised to avoid eating plums and other acidic fruits during a cough.

Coughing individuals should avoid eating plums due to reasons including acidic irritation, increased phlegm secretion, increased gastrointestinal burden, potential allergic reactions, interference with medication absorption, and more. If concerned, it is recommended to seek timely medical consultation. Detailed explanations are as follows:

1. Acidic irritation: Plums are acidic fruits; their acidic components may irritate the throat and trachea, worsening cough symptoms. This irritation may be more pronounced in patients with existing respiratory inflammation.

2. Increased phlegm secretion: Certain components in plums may promote phlegm secretion, exacerbating cough symptoms. Excessive phlegm not only worsens coughing but may also cause breathing difficulties.

3. Increased gastrointestinal burden: Plums contain significant amounts of fiber and fruit acids, which may irritate the gastrointestinal tract, causing indigestion or diarrhea. Patients experiencing coughs along with gastrointestinal discomfort may find their gastrointestinal burden worsened by eating plums.

4. Potential allergic reactions: Some people may be allergic to plums or other fruits, with symptoms such as skin itching, swelling, or more severe allergic reactions. During a coughing episode, the body's immunity is weaker, making allergic reactions more likely.

5. Interference with medication absorption: Certain components in plums may interact with cough medications being taken, affecting drug absorption and effectiveness. Therefore, during medication, plum consumption should be avoided to ensure drug efficacy.

To alleviate cough symptoms and avoid unnecessary health risks, it is recommended to avoid consuming plums and other acidic fruits during a coughing episode. Choose mild, easily digestible foods, maintain adequate hydration, and follow medical advice for treatment.
