Drinking prune juice causes constant flatulence.

Passion fruit juice consumption followed by continuous flatulence is preliminarily diagnosed as being caused by allergic gastroenteritis. Patients can receive symptomatic management through general measures and medication.

In individuals with allergic predisposition, certain components in passion fruit juice may act as allergens. Upon exposure to these allergens, gastrointestinal tissues such as the stomach and intestines may trigger a local non-specific immune response, leading to symptoms including abdominal pain, diarrhea, nausea, and vomiting.

If patients experience the above adverse reactions, they may, under medical guidance, use medications such as promethazine hydrochloride tablets, cortisone acetate tablets, or enteritis relief capsules to reduce the severity of gastrointestinal allergic reactions and alleviate symptoms like diarrhea and abdominal pain. Additionally, supportive measures including a bland diet, adequate rest, and avoiding re-exposure to allergenic foods can help prevent recurrence or worsening of the condition.
