During the treatment process for Helicobacter pylori, it is permissible to eat cake, as there are no specific dietary restrictions. However, it is important to avoid spicy and stimulating foods, as well as strong liquor, strong tea, coffee, etc. Treatment for Helicobacter pylori infection may include the use of proton pump inhibitors such as omeprazole and lansoprazole combined with antibiotics like amoxicillin, clarithromycin, and metronidazole, often in a quadruple therapy regimen with bismuth citrate for two weeks aimed at eradicating the infection. Patients with Helicobacter pylori infection should consume easy-to-digest, bland foods and avoid overly spicy and stimulating foods. (Please follow your doctor's prescription when using medications.)
