Helicobacter Pylori Infection, Causes, Signs and Symptoms, Diagnosis and Treatment.

Summary

This video discusses Helicobacter pylori (H. pylori), a bacteria that can infect the digestive tract and lead to ulcers, gastritis, and even stomach cancer. The infection is common worldwide, though many people show no symptoms. Those who do may experience abdominal pain, nausea, bloating, and unintentional weight loss. H. pylori is spread through saliva, vomit, fecal matter, or contaminated food and water, and the risk is higher in crowded, unsanitary environments. Treatment involves antibiotics, acid-reducing medications, and other drugs to kill the bacteria and promote healing.
