Diet during the treatment of Helicobacter pylori infection should be careful not to eat unhygienic, indigestible and irritating foods. 1. Unhygienic food: raw water, spoiled or moldy expired food will stimulate the activity of H. pylori, and easily complicate other gastrointestinal diseases to reduce the effect of treatment. 2. Indigestible food: such as rice flour, mochi, konjac and other indigestible food will affect the normal function of the stomach, reduce gastric power, and reduce the efficacy of the drug. 3. Stimulating food: During the treatment of H. pylori infection, avoid the intake of stimulating food such as chili peppers and wine, so as not to stimulate the gastric mucosa and secrete more gastric acid, which will affect the recovery of the disease. Patients should use communal chopsticks during treatment to avoid H. pylori cross-infection. Regular work and rest, do not stay up late, strengthen physical exercise to increase immunity and prevent recurrence. If you experience any discomfort, please consult a doctor for timely examination and treatment.
