After treatment, the symptoms of functional dyspepsia can be relieved quickly, but it will recur and whether it can be cured varies from person to person, mainly related to personal eating habits, etc. There is no exact time. Functional dyspepsia often manifests as epigastric distension, belching, loss of appetite, nausea, vomiting and other symptoms. Patients with mild cases can gradually relieve symptoms through regular diet and emotional regulation. If the symptoms are more pronounced, the cause needs to be actively sought. If it is caused by Helicobacter pylori infection, firstly, the bacterial infection needs to be eradicated through a combination of drugs, so the treatment time will be extended. Secondly, the period of treatment will be prolonged for those who frequently drink alcohol or enjoy spicy food. Therefore, once the diagnosis of functional dyspepsia is confirmed, it is necessary to cooperate with the doctor for timely treatment, and at the same time to establish good living habits and quit smoking and drinking. If there is obvious nausea, vomiting, blood in the stool, etc., you need to go to the hospital for gastroscopy or colonoscopy in time.
