Having Helicobacter pylori regardless is a no-no. Helicobacter pylori is a class of bacteria that can colonize the human stomach and cause gastritis, gastric ulcers, gastric cancer and other diseases with a spiral or curved, bluntly rounded end, and can be divided into type I and type II strains. Type I strains are pathogenic and contain the toxin-producing factors cytotoxin-associated protein A and vacuolar toxin A, which are highly virulent, and infection with this type of strain requires regular eradication therapy (a quadruple therapy of two antibiotics, such as amoxicillin and metronidazole, combined with a proton pump inhibitor, such as omeprazole, and a bismuth agent is commonly used at present). Type II strains do not contain the toxin-producing factors cytotoxin-associated protein A and vacuolar toxin A, which are less toxic, but they still require attention to dietary hygiene in daily life and avoiding spicy and irritating foods such as chili peppers, peppercorns, alcohol, ice cream and fried chicken. Helicobacter pylori is contagious and is prevalent in childhood. Infected individuals may experience symptoms such as abdominal pain, nausea, loss of appetite, acid reflux, heartburn, belching (hiccups), and so on. It is recommended to consult a doctor for a clear diagnosis and targeted treatment under the doctor’s guidance.
