1. Mustard is an irritating food. After eating mustard, it will produce a strong irritation to the gastric mucosa, which may cause stomach discomfort or even stomach pain. When this happens, you can eat some easy-to-digest foods appropriately, such as millet porridge, noodle soup, yogurt, etc. to protect the gastric mucosa, which will have a certain effect on alleviating symptoms.

2. If necessary, drugs to protect the gastric mucosa can be taken orally. However, if the symptoms are still not relieved after taking the medicine, you need to go to the hospital for a gastroscopy for a clear diagnosis.
