Abdominal pain after eating spicy food can be considered for two reasons, one is food irritation, which is a normal physiological phenomenon, and the other is pathological factors, including intestinal flora disorders, irritable bowel syndrome, chronic gastroenteritis. If the above situation occurs, the causes should be clarified and treated symptomatically. I. Physiological factors: food stimulation: If patients eat too spicy or pepper-containing food, it can cause excessive secretion of gastric acid or lead to damage to the mucous membrane of the stomach, so intestinal peristalsis will speed up to discharge irritating food, which in turn causes diarrhea. Most of the diarrhea can be relieved by itself after stopping eating spicy and irritating food, and generally no special treatment is needed. Second, pathological factors: 1, intestinal flora disorders: chili peppers contain capsaicin, which can stimulate the mucosa of the stomach to cause gastrointestinal tract dysfunction and intestinal flora disorders; patients can protect the mucosa of the stomach by drinking appropriate yogurt, and can also take probiotics and other drugs as prescribed by the doctor to relieve symptoms; 2, irritable bowel syndrome: after eating spicy and stimulating food, food stimulates the intestinal mucosa causing intestinal spasm, which can cause abdominal pain and accompanied by abdominal pain, abdominal distension, change in bowel habits or stool habits. Pivetonium bromide is commonly used clinically to relieve symptoms; 3. Chronic gastroenteritis: chronic gastroenteritis is a chronic inflammation of the gastric and intestinal mucosa, and abdominal pain symptoms may occur after stimulation by spices. Those with severe symptoms should seek medical attention promptly, and atropine can be used to relieve spasm and pain, while irritating food should be avoided. Note: When intolerant to chili peppers, in daily life, you should try to avoid chili peppers, onions and other spicy diets, and choose light, easy-to-digest foods, such as millet porridge. Usually, you should consume more protein and vitamin-rich food, try to choose high-quality protein such as fish, eggs, soy products, and fresh vegetables such as spinach and chrysanthemum. Avoid excessive stress and keep your mood relaxed to promote recovery.
