Stomach disorders are a group of medical conditions that affect the digestive system. ULCER is a common stomach disorder which is caused by an imbalance in the digestive system, resulting in the formation of sores or lesions in the lining of the stomach or small intestine. DYSPEPSIA is another stomach disorder which is characterized by symptoms such as bloating, nausea, and heartburn. Gastritis is a condition in which the stomach lining becomes inflamed, leading to pain and discomfort. All three of these conditions can be treated with lifestyle changes, medications, and dietary modifications.
