Helicobacter pylori infection, if not treated properly, does not necessarily become more severe. However, if treatment fails, it is necessary to undergo re-treatment. It is recommended to visit a hospital and consult with a qualified gastroenterologist to adjust the treatment plan. The choice of specific medications, as well as their dosages and usage, should be carried out according to medical advice. During the treatment of Helicobacter pylori infection, it is important to avoid overeating, maintain regular meal times and portions, consume easily digestible foods, and eat plenty of fresh vegetables and fruits rich in vitamins. Spicy and irritating foods should be avoided.
