A stomach bacterial is caused by pathogenic bacteria. These bacteria invade the stomach wall, damaging it and causing inflammatory diseases such as peptic ulcers and Crohn’s disease. These bacteria which can cause peptic ulcers are called Heliobacter pylori(H. pylori).
A stomach bacterial infection can be very painful. To alleviate the pain, over-the-counter medications such as Zantac can be used.
Amoxicillin or another antibiotic is also given, to help kill the H. pylori bacteria. Antibiotics are usually taken for about 2 weeks.
