Ulcers are open sores that can develop on the skin or mucous membranes of the body. They commonly occur in the stomach, known as gastric ulcers, or in the small intestine, referred to as duodenal ulcers. These sores can cause pain, discomfort, and other digestive issues, often resulting from factors like bacterial infections, excessive use of nonsteroidal anti-inflammatory drugs (NSAIDs), or high levels of stress. Treatment for ulcers typically involves medications to reduce stomach acid and promote healing. In some cases, antibiotics may be prescribed to eliminate Helicobacter pylori, the bacteria often responsible for many ulcers. Lifestyle changes, such as avoiding spicy foods and reducing stress, can also help manage symptoms and prevent recurrence.
