Stomach pain at midnight after eating raw onions

Generally, stomach pain at night after eating raw onions may be caused by non-pathological factors, or it could result from pathological conditions such as allergies or chronic gastritis. The specific analysis is as follows:

I. Non-Pathological Factors

Raw onions are irritating foods that can stimulate the stomach lining and cause gastric spasms, leading to stomach pain. This is a physiological phenomenon, and symptoms usually resolve on their own after some time. Patients can drink a moderate amount of warm water or honey water, which may help alleviate the discomfort.

II. Pathological Factors

1. Allergy

Certain substances in onions may trigger allergic reactions in some individuals, particularly causing gastrointestinal symptoms such as diarrhea, stomach pain, and nausea. Patients should immediately stop consuming onions. Under medical guidance, antihistamines such as diphenhydramine hydrochloride tablets, loratadine tablets, or cetirizine hydrochloride tablets may be taken orally to relieve symptoms.

2. Chronic Gastritis

Patients with pre-existing chronic gastritis may experience stomach pain after eating raw onions due to irritation of the gastrointestinal mucosa. Treatment may include medications such as omeprazole enteric-coated capsules, metronidazole tablets, or amoxicillin capsules, used according to medical advice.

In addition to the above three causes, other conditions such as colitis, gastric ulcers, or stomach cancer could also be responsible. It is recommended to seek timely medical evaluation and receive symptomatic treatment under the guidance of a physician.
