Gastric ulcers are open sores that develop on the lining of the stomach. They occur when the protective mucus layer is weakened, often due to excessive stomach acid, Helicobacter pylori infection, or the long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Symptoms may include stomach pain, bloating, and indigestion. Treatment for gastric ulcers typically involves medications to reduce stomach acid and promote healing. In some cases, antibiotics may be prescribed to eliminate H. pylori. Lifestyle changes, such as avoiding spicy foods and reducing stress, can also help manage symptoms and prevent recurrence.
