Why does my throat hurt when I eat oranges?

Generally, sore throat after eating oranges may be caused by excessive acidity of the oranges, overconsumption, pharyngeal ulcers, acute pharyngitis, reflux laryngitis, or other reasons. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analyses are as follows:

1. Excessive acidity of oranges: Oranges contain large amounts of organic acids. Acidic substances can irritate the pharyngeal mucosa, damage the mucosal barrier, and cause a burning sensation and pain. Stop consuming immediately, rinse mouth with lukewarm water, and drink moderate amounts of warm water or honey water to neutralize the acidity.

2. Overconsumption: Eating too many oranges in a short period leads to prolonged stimulation of the throat by sugar and organic acids in the fruit pulp, resulting in dryness and pain of the mucosa. Control intake—no more than three oranges per day—and consume with warm water; avoid eating oranges on an empty stomach.

3. Pharyngeal ulcer: When there is an ulcerated area on the pharyngeal mucosa, acidic juice from oranges stimulates the exposed nerve endings, worsening pain and possibly causing difficulty swallowing. Follow medical advice to use medications such as watermelon frost spray, compound chlorhexidine mouthwash, or vitamin B2 tablets, and avoid spicy and highly acidic foods.

4. Acute pharyngitis: The pharyngeal mucosa is in an acutely inflamed state, with congestion and swelling. Irritation from oranges aggravates inflammation, leading to significant pain, accompanied by dry throat and cough. Under medical guidance, take medications such as Lanqin Oral Liquid, amoxicillin capsules, or ribavirin granules. Rest the voice and get adequate rest.

5. Reflux laryngitis: Oranges stimulate gastric acid secretion, which may reflux into the throat and irritate the mucosa, intensifying throat pain after consumption, often accompanied by acid regurgitation and heartburn. Use omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated tablets, or domperidone tablets as directed by a physician. Avoid lying down immediately after meals.

In daily life, choose ripe, slightly sweeter oranges and control portion sizes; maintain good oral hygiene by rinsing the mouth after meals; eat a light diet and avoid overly acidic or spicy foods; seek prompt medical attention for persistent throat pain, and receive targeted treatment based on accurate diagnosis.
