What causes fever every time after eating pomegranate?

Fever, also known as pyrexia, may occur after eating pomegranate due to various factors such as pomegranate allergy, excessive consumption, ingestion of spoiled pomegranate, chronic gastritis, or gastric ulcer. Patients should promptly visit a正规 hospital to determine the underlying cause and receive targeted treatment. The specific causes are analyzed as follows:

1. Pomegranate Allergy

If a patient is allergic to certain components in pomegranate, an allergic reaction may occur, leading to symptoms such as fever, rash, and rapid breathing. Patients should follow medical advice and take antihistamines such as loratadine tablets, cetirizine hydrochloride tablets, or chlorpheniramine maleate tablets for treatment.

2. Excessive Consumption

Pomegranates contain high levels of tannic acid. Consuming large amounts may increase gastrointestinal burden, potentially causing indigestion, bloating, and fever in severe cases. In such situations, gentle abdominal massage may help improve blood circulation and alleviate symptoms.

3. Consuming Spoiled Pomegranate

Spoiled pomegranates may be contaminated with bacteria, mold, or other harmful microorganisms. Ingesting them can irritate the gastrointestinal tract, possibly resulting in fever. Some patients may also experience vomiting, diarrhea, or abdominal pain. Drinking warm water is recommended. If ingestion was recent, induced vomiting under medical guidance—such as using a tongue depressor to stimulate the back of the throat—may help expel the spoiled substance.

4. Chronic Gastritis

Chronic gastritis involves long-term inflammation of the gastric mucosa, which may lead to stomach discomfort, pain, and digestive issues. In such cases, consuming pomegranate may further irritate the stomach, causing diarrhea, bloating, or fever. Under medical supervision, patients may use medications such as omeprazole enteric-coated tablets, lansoprazole enteric-coated tablets, or Xiangsha Yangwei Granules to relieve symptoms.

5. Gastric Ulcer

Gastric ulcers are often caused by poor dietary habits. The acidic juice of pomegranate may irritate the ulcer site, leading to abdominal pain, fever, nausea, and other discomforts. It is advisable to drink warm water and avoid irritating foods such as chili peppers and grilled foods. For more severe cases, medications such as famotidine tablets, ranitidine hydrochloride capsules, or colloidal bismuth pectin capsules may be used under medical guidance.

During treatment, it is important to maintain a balanced and nutritious diet and practice good food hygiene. Avoid consuming spoiled, unclean, or undercooked foods.
