Digestive system disorders refer to a range of conditions that affect the organs responsible for digestion, including the stomach, intestines, and liver. Common disorders include gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and ulcers. Symptoms may include abdominal pain, bloating, and changes in bowel habits. These disorders can result from various factors, such as diet, stress, and infections. Diagnosis often involves medical history, physical examinations, and tests like endoscopy or ultrasound. Treatment options may include lifestyle changes, medications, or, in some cases, surgery to alleviate symptoms and improve digestive health.
