If you are experiencing heartburn and bloating, it could be due to an H. pylori bacterial infection. H. pylori is a common cause of ulcers and gastritis. Symptoms include heartburn, bloating, nausea, and fatigue. To diagnose H. pylori, your doctor may conduct a stool, blood, or breath test. Natural remedies like probiotics, green tea, and olive oil can help fight the infection. To prevent H. pylori, avoid raw meat, wash hands frequently, and eat plenty of fruits and vegetables. Consult a medical professional if you suspect you have an H. pylori infection. Remember to seek professional medical advice before trying any home remedies.
