The main reason for discomfort in the stomach and intestines after treatment for Helicobacter pylori might very likely be due to the consumption of clarithromycin, metronidazole, etc., as metronidazole, clarithromycin, and others can also irritate the gastrointestinal tract. Therefore, it is recommended to take metronidazole, clarithromycin, and other similar medications about half an hour after meals to reduce their side effects. If the patient experiences gastrointestinal discomfort, consider using medications that regulate the gut flora for treatment, such as compounded lactobacillus, bifidobacterium triple live bacteria, and bacillus coagulans, etc.

If the stomach discomfort is quite severe, medications that protect the gastric mucosa, such as magnesium trisilicate or vitamin B6, may be taken. These medications can help alleviate the side effects of other drugs and reduce symptoms of nausea and vomiting.

Discomfort might also be due to incomplete healing. First, it is necessary to return to a regular hospital for a follow-up consultation. If the symptoms have not worsened, it is important to continue taking the prescribed medications as advised by the doctor. Recent dietary habits should include eating regularly, having smaller, more frequent meals, and avoiding spicy, stimulating, and greasy foods. Rest should also be prioritized.
