Treatment for H.pylori infection

[Harup]

Hello, my brother is 18 years old, he gets a dull or burning pain in his belly. It comes and goes away, but he feels it most when his stomach is empty, such as between meals or in the middle of the night. The pain lasts for a few minutes or for hours. He feels better after he eats, drinks milk, or takes an antacid. Doctor has diagnosed that he has got H. pylori infection. I would like to understand how H.pylori attacks our body and what is the treatment for this.

@harup H.pylori attacks the lining of stomach, which usually protects you from the acid your body uses to digest food. Once the bacteria have done enough damage, acid can get through the lining, which leads to ulcers. These may bleed, cause infections, or keep food from moving through your digestive tract. doctor will probably tell your brother to take a few different types of drugs. The options include: Antibiotics to kill the bacteria in body, such as amoxicillin, clarithromycin (Biaxin), metronidazole (Flagyl), tetracycline (Sumycin), or tinidazole (Tindamax). Drugs that reduce the amount of acid in stomach by blocking the tiny pumps that produce it. They include dexlansoprazole (Dexilant), esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), or rabeprazole (Aciphex).
Bismuth subsalicylate, which may also help kill H. pylori along with your antibiotics. Medicines that block the chemical histamine, which prompts your stomach to make more acid. These are cimetidine (Tagamet), famotidine Pepcid, Zantac 360), and nizatidine (Axid).
