Study of Helicobacter Pylori Infection and How Treatment Affects Dyspepsia Symptoms in Adults Aged 18 to 80

What this Trial Is About

Researchers are conducting a multicenter, prospective observational study to investigate how often patients with Helicobacter pylori infection experience dyspeptic symptoms, such as indigestion. The study also aims to follow these patients after they undergo treatment to eradicate H. pylori to see how their dyspeptic symptoms improve over time. This research intends to guide better diagnosis and treatment strategies for patients with H. pylori infection and related digestive discomfort. Participants diagnosed with H. pylori infection confirmed by breath tests or gastroscopy will complete an epidemiological questionnaire and a Functional Dyspepsia Symptom Diary FDSD to record their symptoms. Patients who have dyspepsia and successfully clear the infection will be followed up at 2 months and again at 6 months to assess if their symptoms have improved. The study does not involve any experimental drugs or treatments but focuses on observation and symptom tracking. During the study, patients will provide basic health information and record their digestive symptoms in the diary. Researchers will track the occurrence of dyspepsia at the start and monitor symptom relief after treatment. The follow-up periods at 2 and 6 months after eradication therapy will help measure symptom changes. Participants may be involved for several months, contributing to a better understanding of the natural history of H. pylori-related dyspepsia and treatment outcomes.
