Some functional dyspepsia can be cured, while most of the symptoms are long-lasting or recurring, and require medical consultation to follow long-term comprehensive and individualized treatment. Functional dyspepsia is a dysfunction of the stomach and duodenum that leads to the appearance of a series of symptoms without substantial lesions of the organs. It can be categorized into postprandial discomfort syndrome and epigastric pain syndrome according to the clinical symptoms, and the long-term existence of this disease can lead to insomnia, anxiety and other mental symptoms. Some individuals may be cured with formal treatment, but no definitive cure rates have been reported, and most symptoms persist for a long time. The treatment of this disease is individualized and includes general treatment, i.e., lifestyle improvement and dietary modification. Symptomatic medication, such as acid-suppressing drugs such as omeprazole, is used for epigastric burning and pain; gastric stimulants, such as domperidone, is used for postprandial fullness; digestive aids, such as digestive enzyme preparations, improves epigastric bloating and poor appetite; and antidepressants, such as amitriptyline, improves mood disorders. Although the symptoms of this disease may persist for a long time, or recur, it is still recommended that the people concerned should receive individualized and comprehensive treatment after timely consultation, so as to improve the clinical symptoms or even cure the symptoms. All medications should be used under medical supervision.
