H pylery infection. This circumstances!

Second-line treatment” means a different combination of antibiotics and acid-suppressing medication used only if the first H. pylori treatment fails or the infection is still present. Since you completed a 14-day course and your stool antigen test is negative, H. pylori has most likely been eradicated. Occasional symptoms after eradication are common and may be due to gastritis, acid reflux, functional dyspepsia, or another gastrointestinal condition rather than persistent H. pylori. If symptoms continue or worsen, consult a gastroenterologist for evaluation. An upper GI endoscopy may be considered, especially at your age or if you have weight loss, anemia, vomiting, difficulty swallowing, or bleeding. Avoid self-medicating with antibiotics unless repeat testing confirms reinfection.

1. Completed a 14-day H. pylori treatment course. 2. Had a stool antigen test, which came back negative (suggesting the infection was eradicated). 3. Waited about 1.5 years since completing treatment. 4. Had blood tests, which are reported as normal. 5. Still experiences occasional symptoms and is asking what to do next.

Visit a gastroenterologist for reassessment. * If symptoms persist, an upper GI endoscopy may be recommended, especially because the patient is 63 years old and has a low body weight (44 kg). * Consider evaluation for acid reflux, gastritis, functional dyspepsia, or other gastrointestinal conditions, since the H. pylori test is negative. * Avoid taking another course of H. pylori antibiotics unless repeat testing confirms a recurrent infection.
