Crohn's disease is a chronic non-specific inflammatory disease of the digestive tract, primarily characterized by symptoms such as abdominal pain, diarrhea, weight loss, and abdominal masses. Sometimes, symptoms of vomiting may also occur. This disease is difficult to cure and shows signs of lifetime recurrence, making the treatment of this disease particularly challenging. In cases of vomiting associated with Crohn's disease, oral prokinetic drugs such as mosapride can be used to alleviate the symptoms. Additionally, traditional Chinese medicine can also be taken. By adopting the differential diagnosis and treatment approach of traditional Chinese medicine, oral administration of Chinese herbal medicine can also effectively relieve symptoms.
