Detailed explanation-1: -Erosive (reactive): Erosive gastritis causes both inflammation and erosion (wearing away) of the stomach lining. This condition is also known as reactive gastritis. Causes include alcohol, smoking, NSAIDs, corticosteroids, viral or bacterial infections and stress from illnesses or injuries.

Detailed explanation-2: -You’ll likely need to take antibiotics for two weeks, as well as additional medications to reduce stomach acid, including a proton pump inhibitor and possibly bismuth subsalicylate (Pepto-Bismol). Medications that block acid production and promote healing.

Detailed explanation-3: -The final and most life threatening stage is a Bleeding Ulcer. This type of ulcer is a partial or complete hole in the stomach tissue causing hemorrhage. This condition is a medical emergency and can cause significant GI complications.

Detailed explanation-4: -Stomach ulcers are usually caused by Helicobacter pylori (H. pylori) bacteria or non-steroidal anti-inflammatory drugs (NSAIDs). These can break down the stomach’s defence against the acid it produces to digest food. The stomach lining then becomes damaged causing an ulcer to form.

Detailed explanation-5: -You may have a repeat gastroscopy after 4 to 6 weeks to check that the ulcer has healed. There aren’t any special lifestyle measures you need to take during treatment, but avoiding stress, alcohol, spicy foods and smoking may reduce your symptoms while your ulcer heals.
