What is the cause of a stomach ulcer? A stomach ulcer, also known as a peptic ulcer, is primarily caused by an infection with Helicobacter pylori (H. pylori) bacteria or prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin. These factors weaken the protective lining of the stomach, allowing stomach acid to create painful sores. Other contributing factors include excessive alcohol consumption, smoking, high stress levels, and spicy foods, though these do not directly cause ulcers. Symptoms may include burning stomach pain, nausea, bloating, and indigestion. Proper diagnosis and treatment, including antibiotics or acid-reducing medications, can help heal the ulcer and prevent complications. Visit : https://www.dosepharmacy.com/aciloc-150mg-tablet
