Some people have a spicy diet and heavy taste, and patients have severe stomach pain after eating spicy food, mainly because capsaicin stimulates the gastrointestinal tract leading to increased intestinal peristalsis. Stop eating particularly spicy food, change to light food, take gastric mucosa-protective drugs, or even apply active bacteria that increase gastrointestinal peristalsis. Patients can help pain relief by adjusting themselves. If the pain persists without relief, they can infuse topical sugar saline and adjust their metabolism, and the pain will be relieved naturally. There are clear triggers for the presence of pain after eating spicy food, so rejecting the triggers is the most crucial factor, and attention should be paid to protecting the gastric mucosa and regulating the dysbiosis of flora.
