The high content of irritating substances in raw onions will stimulate the gastric mucosa and cause gastrointestinal discomfort. Therefore, patients with gastritis, gastric ulcers and duodenal ulcers are not recommended to eat raw onions.
Raw onions are irritating to the stomach, but that doesn’t mean eating cooked onions is fine. Regardless of whether it is raw or cooked, the stomach is prone to gas production after eating onions, causing abdominal distension and abdominal pain. Therefore, it is not recommended for patients with gastrointestinal surgery to eat onions.
In addition, people who are prone to allergies and those suffering from itchy skin diseases are not recommended to eat onions.
